Cover Letter Arthur Scott, Senior Purchasing Agent National Grid 175 East Old Country Road. Hicksville, NY 11801-4280 Re: Borrego Solar Proposal for National Grid’s 20MW Solar Phase II Initiative Dear Arthur, Thank you for the opportunity to provide National Grid with a proposal for multiple projects. We are excited by the prospect of being one of National Grid’s partners in construction, and we are confident that the information contained in this proposal will showcase our technical acumen, corporate experience and a wealth of development expertise to execute on these projects. We have thoroughly reviewed the provisions of the RFP and the proposal presented here is in compliance with those specifications. We have specifically used the same outline format as the RFP to make the response easily navigable for National Grid. Additionally we have included an attachment which is a complete written response to your evaluation criteria, point by point, with references to included content of our response. Borrego Solar has developed and installed more PV in the Commonwealth than any other company. To date in MA we have over 50 MW of completed projects and another 40 MW are at various stages of development. We consider ourselves a Developer EPC, and feel that this model is perfect for what National Grid is trying to achieve with the Solar Phase II Initiative. Traditional developers have similar models to Borrego, but they don’t often operate with the mindset of a solar construction company. Borrego Solar has the proven ability to deliver the projects presented in this proposal on time and on budget with over 96 MW of experience in the design and build of commercial solar projects. National Grid will want to have the accountability of a mature developer that can bring realistic projects to closure. In this proposal we assembled a large group of well vetted projects. We’ve also aimed to specifically design a repeatable product offering of viable sites that National Grid can have confidence in successful completion by May 2015. Just as importantly, we have taken great care to work with well-established vendors to provide a state of the art system design that meets National Grid’s advanced inverter control requirements and control systems. This submission includes 38 sites totaling of 29.5 MW for National Grid’s consideration. Interconnection applications and entitlement are already in progress on 10 of the 38 projects. Further, several of our submissions include a 1 MW, 650 kW and a 500 kW option. We understand that National Grid’s objective is to monitor and study various PV project capacities in a variety of interconnection scenarios. Borrego Solar clearly understands this goal and our aim in this proposal was to provide National Grid with a wide spectrum of projects in various areas with various levels of DG saturation.

Site control has been established for all of our proposed sites. The specific form of site control (option to lease or letter of intent) is indicated in the site description attachment for each site. Our landowners are motivated to make these projects a reality, and we will leverage our experience and skills to help NGrid finalize the lease negotiations as needed. As National Grid considers its options for solar development and construction partners, we hope you will take into consideration Borrego Solar’s key strengths:

1. Integrated Development and EPC Services: Borrego Solar offers the full suite of core

competencies necessary to develop and commission large-scale solar PV projects. We have a staff of over 100 full-time employees, including a 19-person engineering team, regional construction managers and site supervisors and a regionally specialized development team. Full-time Borrego staff members will control every stage of the project life cycle – from site feasibility through permitting and. Many solar developers bid on projects before identifying the design and construction resources they will use to execute those projects; this opens the way for schedule delays and cost increases, which might threaten the projects’ funding. Borrego Solar’s all-in-one project approach offers National Grid the opportunity to mitigate construction, budget and timeline risks. Our end-to-end project staff has worked together to commission nearly 100 MW of fully operational solar, and in the process we have created a productive synergy that cannot be reproduced through ad-hoc project teaming arrangements.

2. Policy and Regulatory Expertise: Borrego Solar has been in business for 33 years and building solar in MA for the last seven. We operated profitably through the inception, peak and sunset of numerous incentive programs in many different markets and have flourished in northeast, particularly in Massachusetts. Because solar is still reliant on government funding mechanisms to allow projects to achieve a return that spurs investment, it is essential that responsible solar firms keep abreast of legislative and regulatory developments and develop explicit strategies for taking full advantage of them.

3. Excellence in Corporate Governance: Borrego Solar has grown steadily and profitably year after year, creating a project portfolio of successful solar installations that are completed on time, on budget, and which frequently exceed electricity production goals. Our record is a testament to industry-leading technical expertise, superior construction quality, and sound financial planning. Our in-house quality control department makes certain that we install only the best solar equipment in the industry, complemented by custom warranty terms that reinforce the safety of our clients’ investments. Our operations and maintenance team keeps close tabs on the performance of all the systems in our actively managed portfolio while executing a comprehensive preventive maintenance plan at each site to ensure optimal performance and to minimize down-time.

4. The Ability to Identify and Develop Efficient Projects: We have one of the most experienced project development teams in the Commonwealth. Our team is skilled at



7

identifying and proposing projects that meet and exceed pre-defined goals and criteria. In some cases that criteria is to provide a return on investment and in others, like the case of this RFP it is to provide a platform for research of PV impact on the utility grid. In this case, our development team filtered through hundreds of sites and in this proposal we are presenting National Grid with our 38 sites that best fit the criteria outlined in the NGrid Solar Phase II Initiative with an emphasis on:

a. Limited Civil Expenses – sites are primarily close to the P.O.C., are relatively flat, and require limited clearing, grubbing and grading.

b. Low Utility Upgrade Expenses & a variety of interconnection conditions – We have reviewed screening memos for our sites and have selected sites where we expect low upgrade costs. We have made some exceptions based on NGrid’s request to have some sites on feeders that are heavily loaded already with DG.

c. Entitlement – We have all of the major engineering stamps in house including civil, electrical and structural. We can stamp our own plans and complete the majority of the civil engineering work in house. This means a more efficient project for NGrid and a shorter permitting schedule.

We look forward to the opportunity to work with National Grid to fully develop and construct several projects. Thank you once again for allowing us to participate in your process at this stage.

Sincerely,

TJ Murphy

i) Funding sources

Financing Experience Borrego Solar is one of the most sophisticated and successful developers of solar projects in the United States. We have a history of providing both construction finance and third-party owned finance (PPAs) for our projects. Our strong balance sheet and profitable history allows us to carry significant amounts of capital when called for. Over the past year, we have provided over $15 million in construction financing to our customers. We have over $2.5 million cash on hand and lines of credit totaling $25 million with Bank of the West, Citibank and Taipei Fubon.



10

Over the course of six years of uninterrupted PPA project development we have also secured financing on 64 MW of solar PV projects – an aggregate investment of over $250 million. Our approach to project finance encompasses two commonly used strategies for funding projects, allowing us to have the “best of both worlds” by employing the financing structure that best fits each state, market, project and client. The first strategy involves our own in-house capital leveraged through our sister company, Green Lake Capital (GLC), as an integrated PPA product. GLC is the conduit for sponsor equity contributions to Borrego Solar projects through funding from our mutual parent company, Walsin Lihwa. Lenders and tax equity investors round out the investment structure and bring down the total cost of capital for committed groups of projects, which we call “solar funds.” To date, we have closed five solar funds with our sister company. The second finance strategy is our project development and marketing program, managed by Borrego Solar’s in-house project finance team. This group is tasked with developing the investment plan for each solar project Borrego Solar executes by pairing projects with reliable, market-savvy third-party investors in markets where our sister company does not operate or where there are otherwise benefits of doing so.

Financial Stability Borrego Solar Systems, Inc. has been in the solar electric business since 1980, making us one of the oldest companies in the industry. As a result of the company’s focus on downstream solar project activity in the United States, we have been able to perform very well despite some of the challenges that solar panel manufacturers and European project companies have faced over the last couple years. Our company is profitable by all accounting standards (some solar companies report non-GAAP to avoid showing GAAP losses) and growing. Over the last four years the company has significantly improved virtually every financial metric, including revenues, net profit and shareholder equity. Borrego Solar has demonstrated steady growth throughout the past several years with 2013 being our most successful to date. Our audited financial statements, included within Attachment 1, show $136 million in revenue and $4.2 million in after-tax net profit in 2013. All profits have been reinvested back into the company and Borrego expects to continue to grow profitably. Borrego Solar is a 70% owned subsidiary of the Walsin Lihwa Corporation (Walsin). Walsin is a 55-year-old publicly-traded Taiwanese manufacturing company with over $6 billion (U.S.) in revenue. As a subsidiary, Borrego Solar is audited twice a year to public company standards. Borrego Solar maintains strong banking relationships with multiple financial institutions. The company has lines of credit with Bank of the West, Citibank and Taipei Fubon, totaling $25 million. All lines of credit are in good standing and are within covenant. Additionally, Borrego Solar has procured financing for solar projects from notable institutions including East West Bank, US Bank and National Cooperative Bank.



11

Borrego Solar is fully insured by top rated companies that provide the company with General Liability, Automobile, EPLI, Property and substantial Excess Liability coverage. Borrego Solar is in good standing with our surety companies—Zurich North America (rate A+) and Hanover Insurance Company (rated A)—and has qualified for bonding on projects up to $25,000,000. We have the capacity and ability to support a work program of over $150,000,000. Borrego Solar maintains a D&B rating of 3A1 from Dun & Bradstreet.

j) Audited Financial Statement Copies of Borrego Solar’s confidential 2012-2013 audited financial statements can be found at the end of this proposal within Attachment 1.

k) Pipeline of contracted/anticipated projects Borrego Solar currently has over 58 MW of solar PV array projects under construction on the East Coast, including over 46 MW in Massachusetts alone. Our Operations team is well-equipped to handle 15 jobs any given time. Additionally, our Engineering team typically allows for about 24 projects at a time, or approximately 50 MW. Our engineers can currently take on an additional 25 MW of projects in the design and development phases and are well equipped to meet National Grid’s aggressive timelines for this initiative.

2. Experience and Project References

a) Similar projects for roof-mounted and ground-mounted PV systems

Borrego Solar has over 30 years of experience delivering turnkey solar photovoltaic (PV) solutions. With nearly 100 MW of solar completed or under construction in the Commonwealth, our research indicates we have interconnected more commercial projects in the state than any other provider. A sample list of references is provided below in Section 2.d, and we have included a copy of our Construction & Design set of plans for a 2.6 MW project in Beverly, MA that is finalizing construction now (see Attachment 3). Although no two projects are exactly the same, the sites we’ve identified on our own, along with the National Grid sites provided, mirror the composition of projects we’ve successfully built in the Commonwealth.



13

b) Capability to design, engineer, and construct PV systems

The figure below is a visual representation of Borrego Solar’s approach to solar PV design and development. Borrego personnel control each stage of project execution, from the initial site feasibility to the long term operations and maintenance. As a “one-stop-shop” we are your main point of contact throughout the life of your solar system construction and operation, giving you the best customer service for the long term.

Borrego Solar’s Project Developers and Applications Engineers have in-depth experience with solar in Massachusetts and will move these projects from feasibility to design, determining the most ideal energy producing systems, given the site characteristics and National Grid’s individual project goals. Our Finance team will work with these criteria to determine the best options for minimizing liens on the project when National Grid takes title. Our system designers will then move the projects through permitting and work with our Procurement team to obtain high quality equipment for the installation. All of our engineering is handled in-house, so our team of licensed PEs can quickly and smoothly solve design obstacles and efficiently obtain permits, even for complex projects or those having multiple AHJs. As a technology agnostic PV provider with long standing industry relationships, we source products from a variety of tier one, credit-worthy manufacturers with custom negotiated



14

warranties. All products are vetted and approved by our in-house quality assurance team, known internally as the Resources Group. This team of veterans, in collaboration with our Design and Professional Engineering departments, has established processes to maintain quality control. With their support Borrego Solar has refined production modeling and maintains a historical average of 102% actual production compared to what we model. The Resources Group has also implemented solar design and construction standards that have improved efficiency and reduced installation costs and time. One tool they’ve implemented to improve the quality of our system designs is the creation of a 200-point design checklist that is reviewed and used at three different points throughout the solar design and commissioning process. After the Development and Design phases, the project will be handed off to a single project manager and site superintendent who will direct work at the sites, managing the installation team and controlling the budget. This dedicated team of solar installation experts will partner with qualified, local general and electrical subcontractors during the physical installation of National Grid’s solar power installations. Borrego Solar shall maintain contact through weekly overview meetings with the client and daily site strategy meetings with our subcontractors, project partners and relevant client representatives. Borrego Solar’s Project Managers and Site Superintendents will manage subcontractors before, during and after the installation process and hold them to the same leading safety and quality standards we’ve been known for since 1980. We can provide a copy of our Health and Safety Plan upon request. Once the solar installation is built and is connected to the grid, Borrego Solar can provide additional services both on-site through our Operations and Maintenance plans and within the community through our Marketing team. Our standard O&M offering includes semi-annual site assessments, preventative maintenance checks and round-the-clock monitoring to ensure your system’s continuous operation. This plan can easily be adapted to meet the unique requirements of National Grid and this RFP. Details of our O&M offering can be found later in the proposal within Section 4. Operations and Maintenance (“O&M”). In addition to on-site care, Borrego Solar can work with the National Grid team to develop a full marketing strategy to help the public understand your overall sustainability and energy goals and appreciate how these systems ultimately minimize rate-payer impact in the long-run, by creating local jobs, supporting our nation’s energy independence, and improving the environment for future generations.

c) Capability to construct PV systems (60 kW to 1 MW) Borrego Solar has installed dozens of projects in this size range. Each of Borrego Solar’s installations is overseen by experienced project managers who are assisted by a site superintendent. These individuals are tasked with choosing qualified subcontractors from our preapproved list of electrical and civil construction firms. Our project managers utilize a pre-qualification process to ensure that our subcontractors have extensive experience in their field, offer great quality at competitive prices, and show proof of a stellar OSHA safety record. The site superintendents are Borrego Solar’s quality ambassadors on the job site. They oversee the



15

entire installation process and commission the completed solar array, securing permission to operate from National Grid. Given the tight timelines, regulatory oversight, and catastrophic acceptance clauses contemplated in this RFP, having vast amounts of experience matters. Our project managers participate from the onset of the sales cycle, offering an experienced opinion to our solar design engineers as the project advances through the design stage. This will be especially critical for these projects given some of the non-standard requirements. Construction risks are mitigated from a collaborative, interdepartmental handoff meeting that takes place between the Design, Engineering, Project Management and Operations teams. In addition, while the projects are being built there are regularly scheduled design clarifications and audits that take place between the Construction and Engineering & Design teams. Before commissioning, the project manager and site supervisor review the Quality Assurance log and Construction Control reports (see Attachment 4 and Attachment 4.1) to ensure that the system has been installed in a manner consistent with Borrego Solar’s commitment to excellence in solar design and construction.

3. Construction and Commissioning

a) Description of each proposed PV system We have worked hard to de-risk this whole process for National Grid. By focusing on projects that could be built and financed by Borrego Solar in the event we are unsuccesful in this RFP, we have provided ourselves with a safety net that supports furthering the development of the majority of sites even in the absence of an award. In January of this year, we embarked on a campaign to identify land in the National Grid target areas that met the following criteria:

Parcels of 3 acres or more in one of the 27 named communities

Three – phase lines within 500’ of the array

Minimal tree clearing or grading work required

Easy access from a public way

Neutral impact to abutters and neighbors

No natural heritage issues on-site

Minimal encroachment to wetlands

Solar by-laws or experience permitting in the community was also considered, but not used as a filter

With this set of guideposts, we did a direct mail campaign, enlisted the help of partners, and prospected directly for land-owners that would be interested in entering into a long term lease for their property. Over 150 people expressed interest in this arrangement and we performed a desktop review of each one. For those properties that met our filters we submitted pre-applications to National Grid to better understand the impact an array might have on the local distribution system. For projects that had ‘favorable’ reports from our pre-applications, we executed LOIs with the land-owners and started the process of civil entitlement and interconnection applications. Because we have no assurance from National Grid at this point that these projects will be awarded through this RFP process, we sized each installation to be 650 kW DC to take the most advantage of the ‘unmanaged market’ allocation in the SREC2 program. Knowing that we can build these systems on our own, even in the absence of an award through this RFP, allowed us to take on what would otherwise be an intolerable risk for development spending. While our interconnection applications for most of these projects are submitted with a 684 kW AC / 684 kW DC system in mind, we have been considerate of National Grid’s criteria in our development. In most cases we have presented options in this proposal to construct a system at each site that is either 498 kW AC/DC, 684 kW AC/DC, or a 1 MW AC/DC. While many of the interconnection applications (IAs) we’ve already submitted are only for 684 kW at this point, we reserve the option for submitting an additional IA upon award which would double the size of the system for the purposes of this RFP. Likewise, while our fall-back is to build these sytems on



21

our own, we have initiated civil permitting with the flexibility to build up to 1 MW DC on most sites. For projects with what would conventionallly be considered ‘unfavorable’ interconnection characteristics, but where there was strong interest on the part of the land-owner, we still executed LOIs to define the business terms of the transaction but did not move forward at-risk with submitting IAs or formally initiating the permitting process. Given National Grid’s unique intentions for this soliciation, these sites may in fact offer ideal characteristics for understanding the penetration of distributed PV, but otherwise are not great for private development.

b) Energy production capacity methodology with results in Solar PV Array Info Sheet (see Attachment 2) Production estimates for the project were created using PVSyst, which simulates production for solar generating systems, and weather data from the National Renewable Energy Laboratory (NREL)’s Solar Power Prospector. The weather data includes satellite data from 1998 to 2005, and is available in a resolution of ten-kilometer square grids across the United States. Borrego Solar has created our own module and inverter files to use in the production models. These files have been created through close collaboration with the module manufacturer and an independent engineering firm, and are intended to more accurately represent the real-world performance of the components than the default files that are available with PVSyst. Further, Borrego Solar does not accept PVSyst’s default derate factors. Instead, we specified derate factors based on our experience with real-world systems, internally developed models and algorithms, and strict design standards. These derate factors account for losses such as efficiency loss at high temperatures, reflectivity, soiling, wiring losses, light-induced degradation, low light losses and product deviation from nameplate power. Borrego Solar’s production logic has been validated against actual performance at many locations across the United States. Having been in business for over 30 years and having access to historical production data from our past installations, we have a long track record of accurately predicting PV system performance. Most of our weather data assumptions come from NREL, but we often make adjustments when our real-life production data is not in line. Borrego Solar has applications engineers in every region assigned to validating and fine-tuning our production estimates beyond the data that is available industry-wide. By making our production estimates as precise as possible, we are able to refine our financial models and accurately predict your return on investment. For detailed information on each proposed site’s energy production, please reference Attachment 2.



22

c) Description of proposed site preparation work Identifying sites that required minimal site preparation was a primary driver in our effort. While there is good reason for National Grid to choose sites with diverse interconnection characteristics, positive civil attributes for the system are always in the rate-payers’ interest. Even though each project is unique, we’ve tried to homogenize the starting points through careful selection and vetting. Permitting is, in fact, the first step in defining the required site preparation. Borrego Solar’s team of professional civil and structural engineers have decades of combined experience permitting projects throughout the Commonwealth. We endeavor to be good neighbors and always pay close attention to the potential for abutter concerns and take our responsibilities as stewards of the environment very seriously. Our construction standards are based on years of value engineering experience in every aspect of the construction procces. As noted, we have shepharded nearly 100 MW of systems through the entitlement and permitting process, which drives site preparation and environmental management orders of conditions in each community we work in. As good environmental stewards, we strive to have the least impact on each site we develop by understanding the latest practices in all aspects of civil, electrical, structural and solar construction disciplines. We are experts in land development and siting solar systems with the successful completion of almost 100 MW of construction to date. A summary of required site preperation is described in more detail in Attachment 2 (Solar PV Array Info Sheet) and Attachment 10 (Site Descriptions).

d) Sample for system’s testing and commissioning protocol

Interconnection & Commissioning

Utility grid interconnection constitutes some of the most important and planning-intensive work of a grid-tied PV system. Utility rules for the interconnection of distributed generation (DG) systems are necessarily rigorous in order to ensure both the safe functioning of those systems and the consistent operation of the grid as a whole. In some cases, major on-site and off-site infrastructure upgrades are required in order to accommodate the additional power being fed into the grid. These upgrades can be expensive, and solar developers must make appropriate cost estimates when presenting system pricing to their clients at the time of contract signing. Without a comprehensive understanding and strategic approach to interconnection for each project, solar developers can drastically overshoot their initial budgets and project schedules, costing their clients energy savings. Borrego Solar has successfully interconnected over 1,000 solar PV systems spread across a number of regions and utility territories in California, Massachusetts, New Jersey, Pennsylvania,



23

and Texas. While each electric utility company manages the interconnection of distributed generation in a slightly different way, most institute the same general process, and so every system Borrego designs, builds, and commissions informs the interconnection strategy for the next. When appropriate, Borrego solicits the services of interconnection sub-consultants with deep knowledge of local grid infrastructure and utility policies. Please reference Attachment 5 for our Testing and Commisioning Document for National Grid.

e) Schedule for system’s engineering, procurement, and construction Borrego Solar is accustomed to building projects under aggressive timelines. Working in a subsidized industry we are often faced with deadlines that have catastrophic financial consequences. In addition to all the talent and capacity we’ve already highlighted in our proposal which evidences our throughput, the strategy we’ve employed in submitting sites that otherwise would be financed internally with a Managed Market allocation gives us a distinct advantage when deciding how much risk to take on before and after an award from National Grid. We have considered our methodology carefully. With Interconnection Applications sized to avoid Impact Studies and a streamlined approach to civil entitlement, we are confident we can get all our permissions in place within three months of starting the process. Even with a July starting point for projects initiated upon RFP award, this still provides a reasonable timeline for constructing a significant tranche of projects between 500 - 1,000 kW. Examples of project specific timelines are included in Attachment 2 with each project description.

4. Operations and Maintenance (“O&M”)

a) Capability and cost to provide system’s operation and maintenance Borrego Solar offers a comprehensive O&M plan that gives customers peace of mind that their system is continually performing at its peak capability, and that any system irregularities are quickly and thoroughly addressed.

Borrego Solar’s O&M Director is Matt Murphy, and is stationed in New England and is prepared to address any issues that arise. Our O&M Department has full-time staff who are responsible for monitoring the systems under his management on a daily basis, ensuring that they are producing as expected given real-time seasonal and weather conditions. For more detailed information on our offerings, please refer to O&M Contract within Attachment 6.

Typical site inspection and preventative maintenance

Solar modules are warrantied for 25 years; Borrego Solar believes that your system will produce valuable electricity for longer than that. However, the system will require some maintenance to perform at its peak. Our O&M department will visit your site in the spring to ensure that your system is ready to produce at maximum capacity during the valuable summer months. During this visit, the technician will:

Wash your modules, clearing them of any accumulated dust, which lowers production;

Visually inspect the system for any loose wiring or other safety and performance

hazards, like tree growth;

Log current readings of all of the system’s strings, the instantaneous output of the

inverters, the operating voltage at the inverters, and the cumulative lifetime production

indicated on the inverters;

Check the wires running from the modules to the combiner box to ensure there is no

loose or disconnected wiring, and tighten any loose connections;

Check all of the combiner boxes and replace any blown fuses;

Check that all of the support structures for the equipment, like the array frames, racks

and metal boxes, are securely connected;

Ensure that all labels and safety signs specified in the as-built plans are still in place;

Check that all of the disconnect switches are functional;

Visually inspect the array for cracked or otherwise damaged modules, and record the

location of any that will need to be replaced;



25

Inspect the site for any indications that tree growth may, or may in the future, shade

the array, and notify the customer if any tree maintenance will be required for

maximum production;

Check and confirm the proper torque settings of the wire terminations;

Check and log the voltages of all of the module stringing;

Check the calibration on the weather sensors, which are an important tool in

determining if your system is performing as expected given local conditions;

Check the calibration on the metering equipment;

Visually inspect and plug and receptacle connectors between the modules and panels

to ensure they are fully engaged, and tighten any that are loose;

Check that the strain reliefs/cable clamps are properly installed on all cables and cords

by pulling on them to verify, and tighten any that are loose;

Perform the preventative maintenance recommended by the inverter manufacturer,

including cleaning inverter air filters, verifying up-to-date software releases, and

verifying the system is operating as expected, per the terms of the warranty;

Create and issue a written inspection report.

b) Location of closest PV service and maintenance professionals Our O&M Team, operating out of Lowell, MA, will be responsible for monitoring each solar system on a daily basis, ensuring that it is producing as expected given real-time seasonal and weather conditions. We receive service alerts directly from our chosen data acquisition system, Tri Mark Systems. While these alerts are sometimes notifications that the system isn’t producing electricity, they are more often reflective of system disturbances, communication problems, or lower-than-expected performance from the system. One of the reasons we’ve chosen to use Tri Mark system as our preferred provider is that its monitoring system package includes a full suite of diagnostic tools, which means we can respond more quickly to any problems with your system, including sending a specialist to site with the right equipment for the repair without needing to schedule an initial

26

diagnostic visit. This means less downtime and increased production from your system. Our O&M Team is responsible for handling any alert and communicating a course of action with you. If the alert indicates an outage, we coordinate with you to schedule the arrival of a service technician within 72 hours of the alert.

c) Sample O&M contract Our O&M contract is included within as Attachment 6 and we are provide pricing on the example O&M template provided in the NG RFP as follows:

Legend: Red outline = ground mount array location, Orange circle = interconnection tie-in

System Description: The proposed solar PV array will be installed on a wooded lot located on the southern side of M225. The location is flat and is a great location for the solar PV array. The site host is the Town of Shirley, who is

very progressive and encourages the usage of solar in their community. These parcels of land have been

reviewed for environmental concerns with the local Conservation Commission. The finding are that there

is no concern for endandered species or wildlife. The only potential slow down is the outline of what may be a small creek to the far east of the property. This creek may cause a minor layout change and cause us

to extend the system farther north that it is currently designed.

Site Preparation Work:




The proposed site location will need to be cleared of all trees on the lot, destumped, graded and leveled for a 5% grade to allow for the installation of the racking.

Type: Ground Mounted system utilizing Game Changer Racking. (MA) Module: Jinko - JKM310P-72 (Chinese) Inverter: Solectria - SGI-500XTM-380 (MA) Combiner Boxes: Solectria - ARCCOM-M-PS-24X - arc fault compliant, 1000VDC rated

3 Experience and Project References

Maverick is an experienced, full-service power and communications network utility construction

company. MCC’s construction and project management experience coupled with Petra Systems utility

pole-mount solar experience provide a wealth of capability for the National Grid Solar Phase II Initiative.

3.1 Customer Reference List Customer references for MCC and product/service provider, Petra Systems, have provided reference

lists as attachments to this proposal in the National Grid ARIBA system, per RFP Section 4.2.

3.2 Petra Systems Experience with Contracts of Similar Size and Scope Petra Systems has completed major pole-mount AC module solar projects in New Jersey, California,

Bahrain, Jordan and other locations. Two of Petra Systems’ key projects are described here.

3.2.1 PSE&G Solar 4 All Program – 40MW

In July 2009 the New Jersey Board of Public Utilities approved a 40 megawatt (MW) distributed solar

photovoltaic (PV) project carried out by Public Service Electric & Gas (PSE&G), the largest utility in New

Jersey. The system was deployed and operated by Petra Systems to generate power through smart solar

systems installed on approximately 200,000 utility poles in the more than 300 towns and cities that

PSE&G serves.

Figure 1. Petra Systems Smart Solar Deployed On Utility Poles along Rt. 22 in New Jersey

The pole-mounted solar units provide numerous benefits to PSE&G customers and the State of New

Jersey. The power generated is tied directly into the electric grid to be used by all PSE&G electric

customers. Each pole-mounted solar unit placed in service generates value from:

1) Sale of its electricity and capacity into the wholesale electric grid

2) Solar Renewable Energy Certificates (SRECs) produced

3) Federal investment tax credits

PSE&G monetizes all of this value and the dollars are returned to customers by offsetting the overall

cost of the program. Additionally, the pole-mounted solar units help New Jersey reach its renewable




energy portfolio requirement, which was set in the State Energy Master Plan. PSE&G is taking advantage

of previously untapped resources — space on utility poles — without the cost, permitting and land use.

The project helped to create jobs and drive economic development by making New Jersey a leading

state for solar power.

3.2.2 Bahrain Community Solar — 5MW Project

Let Bahrain Shine is a collaborative project among Petra Systems, Caspian Energy Holdings, the Bahrain

National Oil and Gas Authority (NOGA), Bahrain Petroleum Company (BAPCO), the Bahrain Electricity &

Water Authority (EWA), academia, industry, and government. The deployment builds a foundation for

future smart grid applications such as outage management, AMI, street light control and demand

response. It is the first step in building a smart community with advanced smart energy technologies.

Located in the Awali Community, the University of Bahrain and other locations in Bahrain, the project

provides a 5 MW highly distributed solar power plant with estimated annual energy production of 4.2

million kWh.

Figure 2. Petra Systems Smart Solar Deployed at Awali in Bahrain (Pole and Car Parks)




4 Construction and Commissioning

MCC proposes to develop6.7megawatts (MW) of DC-nameplate solar power generation on National Grid

utility poles in the towns listed in Error! Reference source not found.. The general approach that MCC

proposes is the use of pole-mount solar AC modules directly grid-connected to the 120V distribution

secondary. SunWave AC Modules have been deployed in New Jersey by utility PSE&G providing 40MW

of power on approximately 200,000 utility poles and shown to be extremely flexible for deployment

across a wide variety of conditions

In using these proven and flexible solar solutions, MCC expects to maximize returns for National Grid

while simultaneously providing a model and basis for expansion throughout National Grid territory. The

proposed solution also provides National Grid with significant ancillary benefits including advanced

inverter features in support of Massachusetts DPU and National Grids grid modernization programs.

Installations will be performed by IBEW journeyman linemen provided through Maverick’s affiliate

company, One Source Power (OSP). OSP has a depth of resources in the multiple operational facets

required to complete a construction project of this nature. Depending on the locations awarded under

this proposal, OSP will deploy multiple crews to in order minimize the overall construction timeframe.

Quality Control/Quality Assurance standards will be developed and maintained from initial assembly to

assembly of final as-built documentation.

OSP will strictly adhere to National Grid Safety Standards, as well as their own company safety policies.

Project specific Health and Safety Plan (HASP) and Job Hazard Analysis (JHA) will be developed along

with regular Tailboards completed by each crew. Because on the nature of the install within close

proximity of the general public and vehicular traffic, these specific safety aspects of the work will be

given special attention and closely monitored. One Source Power is also an ISNetworld approved

contractor with an “A’ rating.

4.1 Proposed Sites MCC proposes to deploy the total 6.7MW of pole-mount solar units at the sites which are detailed in

RFP Attachment 2- Solar PV Array Info Sheet which is incorporated with this proposal as an MS Excel

spreadsheet uploaded to the National Grid ARIBA system.

4.2 System Description MCC will provide a comprehensively supported, integrated, PV solar solution comprising the SunWave

Solar AC solution. The SunWave solution mounts on existing National Grid utility poles above the

communications zone eliminating permit issues, and connects directly to the distribution secondary for

increased energy harvest and reduced line losses. Leveraging smart grid type communications, the




SunWave solution also offers advanced inverter features (see 4.2.2.3.1) in support of National Grid grid

modernization efforts.

Operations will be managed via a Maverick built network operations center (NOC), with National Grid

access via secure web browser, using the IntelliView management system connected by virtual private

network to cellular wireless service provider infrastructure bearing communications to the distributed

PV solar solution. IntelliView is also used for reporting system energy production and controlling grid

modernization features.

The solution also includes mounting racks, complete support and training in use of the IntelliView

management portal, and safety procedures around deployments.

4.2.2 Technology Selection Solar AC modules have been proven in recent years to support increased energy harvesting, enhanced

safety and improved deploy ability versus traditional DC string solar solutions. MCC will use SunWave™

AC modules for this project, and or approved equal , enabling highly modular, incrementally deployable

solar units on all possible National Grid utility poles in the selected towns. Further information regarding




the benefits of solar AC modules may be found in Appendix O of this proposal. Cut sheets for major

components are listed in Appendix N and have been uploaded to the National Grid ARIBA system *

The ecosystem is presented in Figure 3. As shown, the Smart Energy Portal views demonstrate data

access via the IntelliView platform. Data center management is part of the NOC services. Figure 4 further

demonstrates the Petra Systems position in the context of electrical transmission and distribution. More

product details are provided in subsequent sections of this proposal.

The SunWave™ solar AC Module which combines a single solar panel, and pole-mount rack. Also

included is the Petra Systems SunWave Communicator™ which is part of the data management and

control system for the solution. Finally, the IntelliView™ management portal solution is provided as a

means of access to system data as well as for management and control.

The SunWave System features bidirectional communication between pole-mount solar units and the

network operations center. Each Petra Systems smart energy module acts as a smart grid appliance and

automatically becomes a two way communications node on a distributed wireless communication

network of Petra Systems devices using standardized ZigBee® protocols over IEEE 802.15.4 physical

layer. This communication network is then aggregated by the Petra Systems SunWave Communicator™

and data is backhauled to the data center. The backhaul may take on any form that is suitable for the

operator, including wired, fiber optic, and wireless. Wireless networks, including WiFi and cellular (the

proposed option), are often used for ease in network deployment. With this smart grid network in place,

all of the management, control, diagnostic, optimization and sensing capabilities of smart grid

appliances can be managed by a network management system (NMS) software module in IntelliView

from the NOC, or remotely through secure web browser.

4.2.2.1 SunWave Smart Grid and Distributed Solar Benefits

As part of any SunWave solar deployment, smart grid benefits are also distributed, enabling significant

electric grid reliability and efficiency capabilities as well as ancillary benefits. The distributed solar units

create infrastructure increasing visibility into the distribution network and adding granularity to the data

available for managing the grid. This in turn enhances the operator’s ability to improve reliability and

efficiency. For example, voltage measurement and optional reactive power controls enable conservation

voltage regulation and volt-VAR optimization on the grid at the operator’s discretion (see section

4.2.2.3.1, Appendix M and Appendix O). Other benefits include potential support for outage

management/restoration systems, theft of service detection and street light control. Petra Systems

smart grid communications can be as extensive or as compact as desired by the system operator, and

many options are possible to expand even beyond the smart grid capabilities described here.




4.2.2.2 PV Solar Module

Petra Systems uses high quality crystalline photovoltaic solar panels from LG for its integrated AC

module solar units. The panels used undergo rigorous quality control, with manufacturing meeting the

highest International Standards: ISO9001:2000 quality and ISO14001:2004 environmental standards.

The modules will meet UL1703 and IEC 61215, and have high conversion efficiency of greater than 17%.

Modules carry a 10 year product warranty and 25 year output warranty and are UL certified as well as

having guaranteed positive tolerance –starting at 0% to ensure power output reliability. PV modules also

carry a wind load of 2400 Pascal and snow load of 5400 Pascal, and have excellent performance under

low light environments (morning, evening and cloudy days).

4.2.2.3 SunWave Smart Energy Module

The Smart Energy Module (SEM) integrated with each AC Solar Module provides individual monitoring,

metering, and command and control of every solar panel as well as advanced inverter features. Detailed

performance data can be obtained as well as rapid identification of underperforming or failed units in a

large deployment. In traditional systems, automatic pinpointing of problem panels is not possible

without expensive additional monitoring equipment.

At the heart of each SunWave Smart Energy Module is the SunWave inverter that optimizes the output

of each individual panel, maximizing energy generation during every moment of operation and

maximizing solar system output as the solution performance varies continuously with changes in

sunlight intensity, shading, temperature and other operating conditions. Additionally, each SEM is

capable of reporting telemetry to IntelliView including solar output voltage, frequency and current, and

grid voltage and frequency, as well as solar energy produced, measured with ANSI C12.1/C12.20

certified 1% accuracy.

Electrical characteristics of the SEM include the capability to support 120V AC as well as the important

safety feature of UL/IEEE anti-islanding by automatically disabling power output until grid connection is

established, or similarly, halting power output if grid voltage disappears.




Figure 5. Smart Energy Module (SEM)

4.2.2.3.1 GridWave™ Advanced Inverter Features

Each SunWave SEM is also capable of GridWave advanced inverter features. More detail is provided in

Appendix M in response to RFP Section 9.9.

GridWave solutions extend the functionality of the Petra Systems SunWave™ smart energy offerings

with capabilities supporting grid reliability and efficiency. GridWave solutions enable distribution utilities

to proactively manage grid effects caused by renewable generation intermittency such as sudden

overvoltage or undervoltage conditions as well as supporting existing grid infrastructure by reducing

switching frequency of on-load tap changers, voltage regulators and capacitors. GridWave solutions,

based on technology developed in coordination with the U.S. Department of Energy’s Solar Energy Grid

Integration Systems (SEGIS) program, are established on the concept of generator emulation which

captures the inertial behavior, as well as finite and controlled impedance of a synchronous generator, to

facilitate stable grid management. Providing a superset of functionality to UL 1741 operation, GridWave

solutions enable utilities to move to next-generation grid reliability functionality while providing for safe

return to standard UL 1741 modes. In doing so, GridWave solutions open the door for utilities to

proactively manage next-generation standards benefits while maintaining required compliance

standards.

Reactive Power (VAR) Management

GridWave solutions support the injection of user-specified fixed reactive power to the full capacity of

device operation, both leading and lagging. When commanding fixed VAR, GridWave limits real power

output as needed to achieve the requested VAR output. More technical background on VAR control can

be found in Appendix O.17.

Automated volt-VAR operation provides voltage regulation support by sinking reactive power if the line

voltage is higher than the selected maximum voltage and by sourcing reactive power if the line voltage

drops below the selected minimum voltage. No operator intervention is required other than to

configure the applicable voltage range as percentages of nominal line voltage from 80% to 110%.




Power Curtailment

GridWave solutions support user-specified manual and automated power curtailment that minimizes

over generation to prevent power reliability issues. GridWave supports fixed power curtailment, limiting

power output to a fixed maximum as a percentage of system maximum from 0% to 100%.

Automated power curtailment manages potential overvoltage situations based on temperature and

frequency. Temperature-based power curtailment is always enabled, derating the power output when

the operating temperature exceeds 65° C. Frequency-based automated power curtailment may be

enabled and disabled as desired. Frequency-based automated power curtailment will limit real output

power to manage voltage increases due to increasing grid frequency. When operating in conjunction

with automated volt-VAR, automated power curtailment is only employed when the overvoltage

condition is beyond the capacity of the automated volt-VAR function.

Voltage Window

GridWave supports user-specified valid voltage windows within which the device operates when

connected to an energized grid. Essentially, this capability allows a GridWave-enabled device to operate

within user-selected voltage windows (wider, narrower, or overlapping UL 1741 voltage window

requirements). UL 1741 specifies two ranges of operating voltage limits; normal and fast-acting. Grid

voltage excursions outside the normal (narrower) limits cause disconnection of the device after a

specified number of cycles. A wider excursion outside of the fast-acting limits causes a faster

disconnection. GridWave solutions follow the same model, but allow the reconfiguration of these limits.

Voltage window parameters are expressed as a percentage of the nominal operating voltage at the

point of interconnection. The narrower “normal” window may be adjusted from 80% to 120% of

nominal voltage, and the wider “fast-acting” window may be adjusted from 20% to 120% of nominal

voltage.

Frequency Window

GridWave solutions support user-specified valid frequency windows within which the device shall

operate when connected to an energized grid. Essentially, this capability allows a GridWave-enabled

device to operate within different frequency windows (wider, narrower, or overlapping UL 1741 window

requirements). Frequency window ranges are 57Hz to 63Hz for 60Hz nominal systems and 47Hz to 53Hz

for 50Hz nominal systems.

Voltage Ride-Through

Voltage ride-through enables continued operation of GridWave-enabled devices for a user-specified

duration within a user-specified voltage limit rather than immediately disconnecting from the grid (as

per UL 1741). Generally, low-voltage ride-through (LVRT) is the key functionality enabling, for example,

grid connection to be maintained during reclosing operations. High-voltage ride-through is also a

capability. The voltage ride-through window is fixed (0% to 120%) of nominal voltage. The user defines




the duration for which the voltage ride-through function will be enabled in the range of 0 to 300

seconds. Within this window, the device will continue to operate and smoothly return to normal

operation if line conditions permit within the specified duration.

4.2.2.4 SunWave AC Module

Figure 6 shows a rendering of the SunWave AC module comprising a PV solar module (panel) the Petra

Systems SEM and pole-mount rack. The SEM is connected via certified cabling to the solar panel DC

output. The AC output of the SEM then connects directly to the grid by connection into the distribution

secondary.

Figure 6. Petra Systems AC Module (PV Solar Module with Smart Energy Module)

4.2.2.5 Solar Racking

The National Grid Smart Solar deployment will use utility pole racks which are integral to the AC module

solution. The rack has a fixed elevation of 30 degrees and may be mounted at any azimuth on a pole. All

rack solutions shall be PE certified for Massachusetts installation. Figure 6 shows the rack as part of the

solar unit solution. An assembly drawing for the rack is also provided with preliminary design package

information. The rack system comes with a range of attachment types to accommodate attachment to

wood, concrete, steel and aluminum poles.

4.2.2.6 SunWave Communicator




The SunWave Communicator is a two-way communications system allowing individual monitoring and

control of each SunWave AC Module. It also enables remote management of a large, geographically

dispersed AC Module population from a centralized location. The SunWave communicator can be

mounted with, or apart from, an array of SunWave AC modules. A photograph of the SunWave

Communicator is provided in Figure 7.

The SunWave Communicator smart grid communications system provides three main functions.

1. Monitors and reports on the operation and health of the SunWave AC modules. This function

consists of recording how much energy is generated and sending maintenance and repair alerts

to the network operations center.

2. Provides tools for remote command and control of the SunWave AC modules. A remote

command can, for instance, enable the generation of reactive power, a feature that increases

line efficiency and helps stabilize voltage levels on the power lines.

3. Provides a cost effective backbone for other smart grid initiatives such as Advanced Metering

Infrastructure (AMI) and load management or demand response programs. The SunWave

technology also provides utilities with grid reliability tools. The systems constantly monitor and

provide real-time status updates on critical operating parameters such as voltage and frequency

thereby supporting automatic power outage detection and faster repair response time.

Figure 7. SunWave Communicator

4.2.2.7 IntelliView Management Portal

The IntelliView smart energy management platform comprises four main functional modules. The

Energy Management System (EMS) module enables the user to access energy generation data via a

secure web browser in the system owner’s operations center (Figure 8). The Network Management




System (NMS) module enables communications network management and control from the operations

center (Figure 9). The Grid Management System (GMS) supports management and control of GridWave

advanced inverter capabilities for distribution grid management. The Lighting Control System (LCS)

manages street light control deployments which are deployed using the Petra Systems communications

network.

The system calibrates and stores the AC Module telemetry and enables access by authorized personnel

from a web based graphical user interface (GUI). In addition, the system provides the command console

used for transmitting configuration commands to the SunWave AC Modules and SunWave

Communicator. The command console also makes possible the ability for remote firmware upgrades for

value added application upgrades in the future.

In addition, the system can be upgraded to provide the command console used for transmitting

configuration commands to the SunWave AC Modules and SunWave Communicator. The command

console makes possible the ability for value-added application upgrades to the system for ancillary

smart grid features such as optional added street lighting control.

4.3 Energy Production Methodology TBD - Provide energy production capacity methodology used with results presented in Solar PV Array

Info Sheet )

4.4 Site Preparation and Installation One of the key benefits of the Petra Systems pole-mount AC solar solution is the ability for rapid, rolling

installation and commissioning, as well as the fact that little or no site preparation is required.

Installation sites, utility poles, are selected by the basic procedure described in this section. The only

unlikely preparation necessary may be trimming of branches causing shading. Generally, shaded poles

are simply bypassed.

Solar units mount rapidly, in 20 to 30 minutes, and begin producing power after just 5 minutes of

connection, bringing the system online safely and enabling incremental commissioning.

4.4.1 Pole Selection

The proper selection of utility distribution poles is an important prerequisite for a well performing

system. MCC will work with National Grid to ensure appropriate poles are selected for solar deployment

and to optimize Petra Systems’ GridWave advanced inverter benefits. General pole selection guidelines

include:

The pole should be in good condition (not leaning or crooked) and structurally sound;

metal/fiberglass/concrete poles (e.g., streetlights,) should be assessed using the effective

projected area (EPA) rating of the pole.

Select a mounting zone that will allow the solar unit to face true/solar south with minimal

shading from nearby structures or trees, or from equipment or wires on the pole. The next best

orientations are facing southwest or southeast if rotation will significantly reduce shading.

The pole must provide a live 120VAC line for interconnection.

The Solar Unit is approximately 30 inches tall (including the mounting channel). If it is being

mounted on the street curb side of a pole adjacent to the roadway, it should not be mounted

lower than the required distance above the roadway per Utility guidelines or the applicable local

or national codes (whichever is more stringent).

For installations on poles where there are no curbs, the Solar Unit should be positioned a

sufficient distance from the roadway to avoid incidental contact by ordinary vehicles using and

located on the travel surface.

When mounting on distribution poles, a minimum clearance from communication lines,

overhead electric conductors, or other electrical equipment on the pole must be per local or

national electric industry standards or Utility guidelines, whichever is more stringent.




4.4.2 Handheld Database Tool

Installation is typically managed using a handheld tool capable of recording GPS coordinates, taking

photographs, scanning barcodes and data-basing typed or written information. Database information

stored on the handheld device is then transferred to the master IntelliView database via secure Internet

connection. Optionally, the installer may manage the installation database prior to transfer to

IntelliView to ensure completeness. Figure 10 and Figure 11 show sample screens

Figure 10. Database View of Pole Mount Installation Data

Figure 1 shows the main database listing including the type of work performed, pole number, GPS

location, GIS information such as map grid number, device serial number, installation height and

azimuth, and installer information. Figure 11 shows a ground level picture of the installation and an

image of the distribution secondary splice drip loop to confirm proper installation.




Figure 11. Database View of Pole Mount Installation Data

4.4.3 Pole-mount Installation Summary

A detailed installation guide is available from Maverick for pole-mount installation of the SunWave AC

module PV solar unit. Typically, solar units are assembled at a staging area and transported by the

installation crews to pole locations for installation. Installation is generally performed using a bucket

truck and a two Journeyman Lineman team. Experienced crews regularly install a unit in 20 to 25

minutes from parking to driving away. The process is summarized here.

Park, deploy safety cones, ready solar unit and bucket

Locate height and azimuth for installation

Mark and drill pole for rack hangar bracket (“wing/arm assembly”)

Hoist and hang solar unit on bracket

Fasten the solar unit in place

Splice the solar unit AC cable into the 120VAC distribution line with drip loop

Dress the cable along the pole and coil excess cable

Connect the AC cable to the SEM output pigtail

Wait 5 minutes for UL 1741 safety timer to elapse and power generation to begin

Confirm AC output of solar unit using clamp-on inductive AC ammeter

Clean area of any waste, remove cones, depart for next installation




4.5 Commissioning Procedure TBD - Sample protocol that describes testing and commissioning for each PV system. Note “rolling”

commissioning during project installation. Commissioning procedure from NOC and w/in IntelliView.

4.6 Development Schedule The detailed schedule for engineering, procurement and construction of each PV system is incorporated

with this proposal as a separate document uploaded to the National Grid ARIBA system.




5 Operation and Maintenance

MCC, will provide operations monitoring and data hosting services for the required five year duration of

the program. MCC will provide direct maintenance as required.

MCC O&M Services comprise the Network Operations Center (NOC) services and IntelliView. The Petra

Systems offering features remote monitoring services, energy production reporting and advanced data

analytics coupled with highly skilled management of Petra’s SunWave smart solar energy solutions. This

powerful combination allows customers to intelligently manage their PV systems by maximizing energy

production, minimizing downtime, and ensuring maximum return on PV investments.

5.1 Network Operations Services The Maverick NOC services leverage the expertise of the Petra Systems trained technical staff to be the

first line of defense in managing, monitoring and troubleshooting the system. This model allows

customers to focus on other key functions of their operations, while deriving full benefits from their

investment.

IntelliView Access. The ability to remotely manage the network and assets are enabled by

having access to IntelliView.

Hosting Services. Petra Systems will provide hosting services as part of the NOC services which

enable the secure hosting of data associated with the network and energy management

systems. Network Engineers will support this service to ensure reliability of data/information is

continually accessible to the customer.

Data Storage. Storing data for a period of time is important for the management and technical

teams alike. With historical data, issues, alerts and other relevant information is readily

accessible for reporting, troubleshooting and even forecasting. Petra Systems will work with the

customer to ensure that the guaranteed period of time for Data Storage is adequate for their

specific application and organizational needs.

Secure VPN. Maverick will ensure secure connection to the data center by Virtual Private

Network (VPN). This will ensure that only authorized users are able to have access to data which

may be private or critical.

Configuration Management. Petra Systems NOC personnel will maintain device and system

configuration details, ensuring the all associated information is acquired and logged. This will be

performed upon installation. In the event a change is required, the NOC personnel will

communicate with required party requesting the change, ensure that all affected parties are

notified of the request, and ensure that the impact of the change is addressed and approved.

The NOC personnel will update changes to the configuration as required.

Provisioning. Installation information required to be entered into IntelliView, in order to

activate each end device and over-all system will be performed during provisioning.

Technical Support. If issues arise when the end devices are installed, the NOC personnel will

provide their expertise to assist the customer’s operations center in troubleshooting issues to

lead to resolutions. This level of support can also be available for maintenance of the system.




Field Deployment Verification. NOC personnel will verify that the designed system parameters,

both energy and network actual, are comparable to the actual installed data. If the variances are

out of range, the NOC personnel will perform the required analysis to determine what steps are

needed to meet the required thresholds.

Burn In. NOC personnel will ensure units that each unit which undergoes a field acceptance test,

subsequently undergoes a burn-in test. This is a monitoring 30-day period, where initial

accepted values are compared and evaluated, to ensure that each parameter meets expected

thresholds. This testing process gives another layer of assurance that the system, as installed at

each location operates reliability.

Periodic Preventative Maintenance. On a periodic basis, typically every quarter, the system is

‘scrubbed’ to evaluate how units are performing. A view of a snapshot of network and energy

performance is also trended over this period, giving the ability to identify issues before an

outage or loss of generation occurs. Failed equipment identification, remote upgrades for

system patches are performed as part of this process.

Triaging. NOC personnel will identify issues and route resolution requests to appropriate parties

efficiently, thereby reducing resultant resolution time.

Troubleshooting. NOC personnel will use all steps in as network managers to understand nature

of each identified issue and ultimately determine the root cause. Subsequent identification of

problem resolution will be performed

Operations and Maintenance Dispatch. NOC personnel will contact (via phone or email as

appropriate) and follow-up with Customer Field Personnel, until adequate problem resolution

occurs.

Reporting. Monthly status report will be created and generated, providing information on

Energy Settlement, Installation Status, Network Health and other management required data.

RMA. NOC personnel will investigate failures and identify when units are required to be

returned to manufacturer. Since the Return Material Authorization (RMA) will be identified and

addressed by Petra Systems, the process may take place in a more efficient manner.

System Access Administration. Petra Systems NOC personnel will manage user administration –

personnel logins, passwords etc.

5.1.1 Network Operations Center

The Network Operations Center (NOC) will be a state of the art, secure facility at Maverick headquarters

in Boston which houses the highly trained and skilled personnel, equipment and applications utilized to

manage and/or support the smart grid network and assets. The NOC enables engineers to monitor the

deployed assets, coordinate activities, as well as investigate any potential performance and

communications alerts.




Figure 12. Petra Systems Operations and Support Engineers

5.2 Maintenance Necessary field maintenance of the projects shall be completed by MCC through its IBEW affiliate One

Source Power

One of the significant advantages of a pole mount solution is that it requires no scheduled field

maintenance. Additionally, the system is inherently reliable as a single unit, or even several unit, failure

does not affect the performance of the remainder of the system. See Appendix O.7 and Appendix O.9

for more detail.

Appendix O – Technology Differentiation This section discusses the technology and many benefits of a pole-mount AC module solar solution

versus a traditional rooftop or ground mount solar array. Also described are other inherent advantages

such as no scheduled maintenance, benefits of a distributed deployment, and advanced inverter

benefits. This Technology can be rapidly deployed and installed. It utilizes existing National Grid

Infrastructure.

O.1 Solar Solution Differentiation Summary Table 15 shows a summary comparison of the key features and benefits of the Petra Systems SunWave

AC module solutions versus traditional DC string arrays. Petra Systems SunWave AC Modules are the

safest, highest performing option for distributed deployments and small to medium (e.g. < 10 MW)

arrays, and are the only solution type offering immediate energy generation, simplified alignment and

repurposable deployment. It is for these very reasons that Petra Systems champions utility-grade AC

solar modules and is the industry leader in utility-owned solar AC module deployments.

Table 15. Petra Systems SunWave AC Module – DC String Array Comparison

Feature Proposed AC Module Solar Array

Traditional DC String Array

Safety Inherently Safe Multiple Hazards

High Voltage DC Not applicable, no high voltage DC Yes, up to 900V DC

Automatic Shut-off Yes, per panel Yes at grid, but panels may remain energized

Deployment Highly Fast and Flexible Requires extensive planning and long build-out cycle

Adaptability Scalable, upgradable, repurposable

Site specific design

Lead Time Immediate and ad hoc Permits, site work, system design

Performance Maximum per-panel performance in all conditions

Entire string subject to performance of worst panel

Reliability Potential failure limited to individual module

A single component failure may bring down all or part of system

Diagnostics Monitoring, reporting and control at individual panels

Not at panel level, any solution must be specifically designed

O.2 Traditional DC String Array Solar Systems The traditional DC string array architecture combines solar panels in a DC series configuration, much like

batteries are “stacked” in a common flashlight. The series configuration creates an aggregate DC voltage

from all of the connected panels, often 600 – 900V DC, which is then fed to an inverter which in turn

generates an AC voltage from the entire “string” of solar panels. A diagram of a traditional DC string

solar array is shown in Figure 13.



O-2

Successful string inverter installations require careful system design. Miscalculation of worst case

maximum open-circuit voltage of a solar PV panel string is a common cause of inverter failure.

Additionally, panels within a string need to be very closely matched, requiring the same manufacturer,

age, condition, and panel orientation to avoid a significant reduction in the power output of the whole

string. Similarly, special attention is needed to ensure that a string does not become partially shaded, for

example, by a building, a tree, or nearby objects, or the entire array will suffer from reduced output.

One more significant consideration of this type of solution is that, because traditional DC string array

solar solutions are inherently arrays of multiple panels, it is extremely likely that deployment site

planning is required, which may include the requirement for obtaining permits and development of grid

connection resources, and very limited redeployment capability for the resources.

Figure 13. Traditional DC String Array Solar Architecture

O.3 Modular AC Grid-tie Solar Solutions The proposed modular AC grid-tie solar solutions are a recent advancement based in the innovation and

economy of high-performance panel-level inverters basic module of a solution comprises a single solar

panel with an integral panel-level inverter, producing an AC output directly at the panel. Additional

electronics may be included in the module to perform other functions, such as smart grid diagnostics

and control. AC module outputs are then connected to the utility grid in parallel, as shown in Figure 14.

Because no series or parallel DC connections are made outside of the panel module, all DC wiring

remains at the relatively low voltage level of a single panel (typically less than 50V DC).

Since AC solar modules are connected in parallel and do not need specialized electrical design, they can

be deployed one at a time providing a pay-as-you-go option. As few as one module may be installed at a

time, and the array later expanded or repurposed to another site, without large redesign or cost

penalties. This modularity also enables installation of an array of modules without needing to align them

all at the same elevation angle or azimuth. The result is the ability to fully populate all potential areas

with solar generation without the cost of adding a central inverter for each configuration.
