1. INTRODUCTION

R.G. Vanderweil Engineers, LLP Power Group (Vanderweil) was retained by the University of Maine (UMaine) to perform an Energy Upgrade Screening Study which addresses the feasibility of installing combined heat and power (CHP) and a third-party Photovoltaic (PV) solar energy generation farm. This study was performed in accordance with Vanderweil’s proposal dated February 24, 2016. This report summarizes the various investigations performed by Vanderweil and presents the results for the inclusion of CHP and PV generation.

2. EXECUTIVE SUMMARY UMaine is exploring opportunities to implement energy solutions at the Orono, ME campus. The UMaine System’s objectives are “to ensure safe, reliable, efficient, economical, and environmentally responsible services to each campus”. The focus of this Energy Upgrade Screening Study is to review energy savings for alternatives that include Combined Heat and Power, Solar Energy Generation, and Elimination of Summer Steam Generation. This study reviews annual savings and costs associated with these alternatives to examine the merits of pursuing these energy opportunities further. This study updates a previous analysis performed by Vanderweil in 2010. Since 2010, UMaine installed a 60,000 lb/hr gas-fired steam boiler, Boiler #8, in the existing steam plant to replace Boiler #3 and #4. The new boiler increases the overall efficiency of the heating plant and reduces UMaine’s dependency on their #6 fuel oil fired boilers. Both the efficiency improvement and reduction in oil consumption result in significant cost savings. UMaine believes it can also expand energy and cost savings through Combined Heat and Power and Solar Energy. A CHP installation on the east side of campus would add resiliency to the steam system by back-feeding steam from the opposite side of campus. On loss of either the existing boiler plant or the CHP plant, steam can be distributed to campus with minimized interruption. The current steam distribution system is fed radially from the existing steam plant making the campus vulnerable to steam outages if a main steam pipeline were to fail. CHP would also increase campus energy efficiency through generation of electricity while making use of the waste heat as steam. A boiler would operate at minimum load in the existing heating plant as back-up and to generate electricity with the existing steam turbine generators (STG). Solar generation on the east side of campus would benefit UMaine by adding low cost renewable energy generation on campus. The solar site would be built and operated by a third-party developer who would maintain the solar farm and sell generated electricity to UMaine. The developer would retain the renewable energy credits (RECs). Vanderweil performed a load analysis using metered and logged data provided by UMaine to size CHP and potential solar energy farm. Competitive Energy Services (CES) provided utility cost and campus growth forecasts to predict energy use and costs over the next 20 years. The analysis results are presented in the table below. Detailed output is presented in Section 4 - Energy Upgrades and in the Appendix.

Option 1 consists of three (3) alternatives without CHP. Solar energy generation provides more cost savings than eliminating summer steam load. Solar cost savings assume that the solar farm is built, owned and operated by a solar energy developer. It is assumed that energy is not exported to the utility. It is possible to export electricity and it may result in additional cost savings, however, interconnection issues with the utility would have to be addressed in more detail. Option 2 consists of four (4) alternatives for a CHP plant operating thermal load following. The facility would be located on the east side of campus adjacent to the east substation located off Rangeley Road behind the Facilities Management building. The new plant would be electrically connected to the east substation and mechanically connected to the steam and condensate distribution system through a new steam loop from the Hilltop to the DP Corbett area. The analysis results in significant savings when compared to the campus without CHP, but less savings than a CHP plant operating electrical load following (Option 3). Alternatives B, C, and D combine CHP with solar generation and elimination of summer steam load. These alternatives show minimal additional savings due to CHP interaction with other alternatives included. Option 3 consists of four (4) alternatives for a CHP plant operating electrical load following. The CHP facility would be the same as Option 2 with operational differences. Like Option 2, the analysis results in significant savings when compared to the campus without CHP. Alternatives B, C and D combine CHP with solar generation and elimination of summer steam load. These alternatives show minimal additional savings due to CHP interaction with other alternatives included. Twenty (20) year present value costs show a similar trend with and without carbon credits.

3. LOAD ANALYSIS AND CONFIGURATION SELECTION Data provided by UMaine was used to form the basis of the analysis. This data was used to produce electrical and thermal load profiles which were used to determine annual purchased electricity and natural gas consumption. A summary of the campus’s loads are shown graphically below. ELECTRICAL LOAD

Vanderweil reviewed metered data provided by UMaine. The data was polled in 15 minute increments over the course of an entire year. The peak electrical load is approximately 8,500 kW. The load profile is shown in the graph below.

STEAM LOAD

UMaine provided daily steam generation data. Daily steam generation was divided by 24 hours to calculate average hourly data for each day. The campus uses steam primarily for heating, generating hot water, and other HVAC uses. Two 250 ton absorption chillers use steam in the summer months to generate chilled water. A significant amount of steam is used to power the steam plant which includes steam driven boiler feed pumps and boiler forced and induced draft fans. During the summer months, a significant amount of the thermal energy (e.g. steam) use is due to distribution piping losses.

GENERATION EQUIPMENT SELECTION Based on facility load analysis, Vanderweil developed a potential cogeneration system upgrade which is summarized below.

The campus electrical demand varies between 3,200 kW and 8,500 kW. A CTG sized for electrical output less than 6,000 kW will be able to operate continuously without shutdown due to low load. CTG’s operate more efficiently at full load than at part load. The load duration curve shows that the load is greater than 4 MW, 77% of the time indicating that a 4 MW cogeneration plant would be a good fit electrically for UMaine.

Steam Load Profile



The steam load profile shows that campus load is greater than 20,000 lb/hr for most of the year. During the heating season, the load increases above 40,000 lb/hr and peaks over 100,000 lb/hr (full peak is not seen due to using calculated average hourly data). A review of the campus’s electrical load duration curve shows that a Solar Centaur 50 CTG is a good fit for these profiles. The Centaur 50 generates 4,500 kW nominal at standard conditions. The CTG’s Heat Recovery Steam Generator (HRSG) produces approximately 25,000 lb/hr without the use of supplemental duct burners. Duct burner operation can increase the HRSG steam production to 48,000 lb/hr. The CTG could operate most of the year at full load. During the heating season, supplemental duct burner firing would produce additional steam capacity at high efficiency. Duct burners would be shut down during the summer months. Study cases that include both cogeneration and photovoltaic electrical production, would include 1,500 kW AC of PV solar panels with 4,500 kW of cogeneration. The load duration curve for daylight hours shows diminishing returns above 6,000 kW of electrical generation. This is seen by the steep slope above 6,000 kW. A standalone PV installation would be sized for 6,000 kW AC, where the alternating current size is based on inverter capacity. The direct current size would be 8,000 kW, the installed capacity of the photovoltaic cells. Typically, inverter capacity is sized lower than the total capacity of the solar array. This practice is to maximize the value of the combination. The DC panel capacity is oversized to allow for an increased generating capacity earlier and later in the day when the sun is at a lower angle of incidence.

4. ENERGY UPGRADES UMaine identified three energy upgrade options for analysis in this study. The first option consists of updating the base case energy model developed in 2010. Since 2010, UMaine installed a high efficiency 60,000 lb/hr gas-fired watertube boiler with an economizer. The other two options analyze adding a Combustion Gas Turbine. OPTION 1 - EXISTING CAMPUS/BASE CASE WITH ALTERNATIVES The base case consists of the existing campus steam plant that houses four watertube steam boilers sized at approximately 60,000 lb/hr each. Boiler #7 and new Boiler #8 are used as the primary source of steam generation with Boilers #5 and #6 serving as backup. The combination of Boilers #5, #6, #7 and #8 provide full redundancy for the peak campus steam load between 100,000 lb/hr and120,000 lb/hr.

Note: 1. Base Case Purchased Natural Gas includes 272,711 equivalent therms of fuel oil consumed.

Option 1 has three (3) alternatives to the base case. 1A - Eliminate Summer Steam Load The summer steam load consists of campus loads such as domestic hot water, absorption chiller cooling, and HVAC. To generate steam, the campus steam plant uses parasitic steam for powering boiler draft fans, boiler feed water pumps, and by the deaerator. Localized hot water generation would be employed to replace campus steam. Decentralized hot water boilers and hot water heaters would be installed to generate domestic hot water and hot water for HVAC. Electric chillers would be installed in Barrows and Aubert to replace steam consuming absorption chillers. The chillers are sized 287 tons and 200 tons respectively. Note: In order to eliminate steam usage in the summer, the existing steam piping system will need to be evaluated to ensure that the change in pipe temperature due to de-energizing it in the summer will not compromise the integrity of the steam distribution system. 1B - Solar Energy Farm UMaine has a large plot of land on the east side of campus. It is divided into two usable parcels of 17 acres and 51 acres. A qualified solar energy contractor/developer could construct and maintain arrays of photovoltaic solar energy panels on this property. It is estimated that the site can support a 17.5 MW solar energy installation with inverters sized to deliver a maximum of 13.1 MW AC. Based on the campus load duration curve, an 8,000 kW array with a 6,000 kW AC inverter capacity would be a reasonable size to assume at this time, reserving the remaining land for possible future expansion. The installation would be installed behind UMaine’s electric meter and sold



to the university by the developer at a competitive rate. The developer would own the Renewable Energy Credits (RECs). 1C - Combination Eliminate Summer Steam Load and Solar Farm This alternative combines elimination of the summer steam load and the installation of a third-party solar energy farm. This alternative would realize an increase in summer purchased electricity due to the conversion of absorption chillers to electric centrifugal chillers and summer shutdown of the steam turbine generators in the heating plant. OPTION 2 - COMBINED HEAT AND POWER (THERMAL LOAD FOLLOWING) Option 2 has four (4) alternative cases for a new Combined Heat and Power (CHP) plant located on the east side of campus adjacent to the east substation near the service building. These alternatives calculate energy consumption with the CHP plant thermal load following. Thermal load following attempts to minimize thermal losses by reducing turbine load when campus thermal energy/steam demand is less than the potential unfired output of the turbine exhaust. On low campus steam demand, CHP controls will vary the CTG load in attempt to match steam output to campus demand. On very low campus steam load, the CTG will operate at minimum load. On very low campus electric load, the CTG will shut down. This CHP plant would be electrically connected to the east substation and mechanically connected to the steam and condensate distribution system. A new 4” pumped condensate pipeline is needed with these alternatives to bring condensate return from the College Avenue steam plant to the new CHP plant. The new CHP facility would include power island equipment and balance of plant equipment required for a new steam and power generation facility.

2A - CTG with Heat Recovery Steam Generator (Thermal Load Following)

This alternative is the installation of a CHP plant based on a 4.5 MW natural gas fired combustion turbine generator (Solar Centaur 50) with an HRSG utilizing duct burners. The HSRG would be capable of producing approximately 25,000 lb/hr of 150 psig saturated steam unfired, and up to 48,000 lb/hr of steam with the addition of a duct burner. The existing boilers in the College Avenue steam plant would be required to meet steam demand greater than 48,000 lb/hr and to provide backup in the event of an equipment trip or maintenance outage. Most of the time the HRSG will operate without thermal venting or bypassing. Subject to ME DEP permit approval, the new CHP power island equipment would be located in a new building near the east substation. CTG could be designed to burn two fuels (natural gas and #2 oil) to provide fuel redundancy in the event of natural gas curtailment. The HRSG duct burner would burn natural gas only. 2B - Eliminate Summer Steam Load The summer steam load consists of campus loads such as domestic hot water, absorption chiller cooling and HVAC. To generate steam, the campus steam plant uses parasitic steam for powering boiler draft fans, boiler feed water pumps and by the deaerator. Localized hot water generation would be employed to replace campus steam. Decentralized hot water boilers and hot water heaters would be installed to generate domestic hot water and hot water for HVAC. Electric chillers would be installed in Barrows and Aubert to replace steam consuming absorption chillers. The chillers are sized 287 tons and 200 tons respectively. The CHP plant would operate at minimum capacity from June through the end of August to generate electricity, keep steam distribution piping warm to minimize thermal cycling and serve as backup. The existing steam piping system should be evaluated to ensure that change in pipe temperature due to de-energizing the existing heating plant in the summer will not compromise the integrity of the steam distribution system. 2C - Solar Energy Farm UMaine has 68 acres of land on the east side of campus that can be used to develop a solar energy farm. A qualified solar energy contractor/developer could construct and maintain arrays of photovoltaic solar energy panels on this property. Based on the campus’s load duration curve, combined generation capacity of CHP with a solar energy farm was selected at 6,000 kW (4,500 kW CHP generation and 1,500 kW solar generation). Solar panel capacity will be 2,000 kW with 1,500 kW of AC inverter capacity. The solar installation would be installed behind UMaine’s electric meter and sold to the university by the developer at a competitive rate. The developer would own the Renewable Energy Credits (RECs). 2D - Combination Eliminate Summer Steam Load and Solar Farm This alternative combines elimination of the summer steam load and the installation of a third-party solar energy farm.

5. METHODOLOGY

An hourly cogeneration analysis was performed for each of the options and alternatives to determine an expected energy consumption and cost. UMaine provided electric, steam, and gas use profiles for the period of November 2014 through October 2015. UMaine also included electric generation from its two back pressure steam turbines. Electric demand (kW) data was provided as 15 minute readings. Natural gas consumption and steam production were provided as daily totals. Electric demand data was combined to form an hourly electric profile for an entire year. Daily natural gas and steam totals were divided evenly over 24 hours for each day to generate an hourly profile for an entire year. Hourly electric, natural gas and steam profiles were entered into an analysis that calculates hourly energy consumption using equipment sequencing and equipment part load performance data. The results from the hourly analysis is summarized into monthly summary totals as presented in Appendix A. Average hourly DOE-2 weather data for Bangor, ME was used in the analysis. Using manufacturer provided part load performance data at various ambient conditions and engine loads, equations were developed to predict electrical generation, steam output and natural gas consumption. Cogeneration part load performance was provided by Solar Turbines. HRSG performance data was provided by Cleaver Brooks. Hourly ambient dry bulb temperature was used in the calculations to determine the maximum capacity of the CTG. If the electrical load of the campus is greater than or equal to the maximum engine capacity, the CTG will operate at 100% load. If the campus load falls below the capacity of the CTG, then the CTG is run at part load. Under certain circumstances, the engine is shut off if the campus load falls below a minimum load threshold as determined by the engines efficiency and emissions (typically 50% load). Based on the ambient temperature and percent load of the engine as determined above, the output of the unfired HRSG is determined from another developed equation. If the unfired HRSG steam output is insufficient for the campus steam load, supplemental duct firing will occur up to the max HRSG output. The existing boilers will meet the remainder of the steam loads, if any. Similar equations are used to determine the CTG fuel gas consumption. Thermal load following alternatives attempt to match the thermal output of the CTG and HRSG to the campus steam load. The CTG is allowed to remain in operation at minimum load when the campus load is less than the HRSG’s unfired output. This mode of operation also applies to the ‘eliminate summer steam load’ alternatives. Thermal losses will occur during those hours. It is assumed that there is a greater cost benefit operating the CTG at minimum load than shutting the CTG down. Excess thermal output will be vented as steam or bypassed to the stack as hot gas exhaust via a diverter damper. Solar alternatives assume that electricity is generated without export and that the alternatives that include cogeneration assume electrical generation is modulated to maintain a minimum 200 kW import. The solar installation assumes a fixed axis array. The financial Pro-forma analysis compares alternatives on a 20 year present value basis. First year energy costs were calculated by utility rates supplied by Competitive Energy Services (CES). Monthly average predicted utility rates were provided for natural gas only. Annual average blended rates were provided for purchased electricity, solar produced electricity and carbon credits. Blended rates include the effects of several billing components such as energy charges, demand charges, generation rates, transmission rates, and distribution rates.



CES also provided a forecast of 20 year annual rate increases/decreases. UMaine provided a prediction of electric and thermal use profile increases over 20 years. The rate forecasts were applied to the average annual cost of electricity and natural gas to extrapolate 20 years of average annual rates. The use forecasts were applied to the total annual electric and natural gas consumption calculated for each alternative to extrapolate 20 years of annual energy consumption. Future cost of energy was calculated by the product of future energy consumption and future average energy cost for each year. CES/UMaine data is presented below.

6. CONCLUSIONS

The potential energy upgrades and savings summarized above show some basic trends:

� Thermal Load Following vs Electric Load Following: Electric load following results in greater financial savings. This is due to more electric generation when electric load following. Thermal load following reduces CTG load to reduce thermal venting or bypass. Although thermal load following increases overall cogeneration plant efficiency, it is restricts the CTG from operating, particularly during the summer months when operating the cogeneration plant is most attractive. During the summer, electric rates are typically higher and gas rates are lower. Per CES, the average gas rate in the winter can be almost double the lowest month’s average during the summer. Given the current electric and gas rates, it is more attractive to operate a cogeneration plant that follows the electric load profile.

� Eliminate Summer Steam Load: Eliminating summer steam load shows moderate savings when performed without cogeneration. Elimination of steam to the campus will require additional electrical consumption from 500 tons of added electrical centrifugal chillers, reduced energy from existing cooling tower fans and condenser pumps, the addition of hot water pumps required for new summer boilers, and the loss of STG cogeneration in the steam plant. The benefits of eliminating steam consumption at the steam plant and eliminating steam piping losses outweigh the added purchased electricity in the option without CHP.

However, when the eliminate summer steam load alternative is combined with CHP, the CHP plant would bypass or dump waste heat during the summer if it were to operate. Minimal additional savings occur with when combined with CHP.

� Solar Farm Generation: A solar farm without cogeneration results in a modest financial benefit to UMaine. Combining solar generation with CHP results in marginal cost savings. Two factors that limit savings are a reduced solar farm size from 6,000 kW AC to 1,500 kW AC and reduction of CTG generation due to the interaction between solar and CHP generation.

� Combination Eliminate Summer Steam Load and Solar Farm Generation: The combination of the two alternatives has the best cost savings when CHP is not installed. Due to interactions between the combined alternatives and CHP, cost savings with CHP are marginal. The combined effect limits the amount of generation available for the CTG, especially during the summer months where operating the CTG is most attractive.

� Annual Electric Load Growth: The present value analysis was run with 3% electric load growth and

1% electric load growth. Present value costs are reduced when the model is run with 1% electric growth except Option 1A “Existing Campus and Eliminate Summer Steam Load”. Option 1A results in an increase in electrical consumption due to new electrical equipment required. Greater annual electrical consumption results in less cost savings and a higher present value cost. The trend of 20 year present value costs between options was similar.

A table comparing the results between 1% electric growth and 3% electric growth is included in Appendix B.

RECOMMENDATIONS

The study results show that further consideration of CHP and Solar Energy is recommended. Electric load following has the most savings based on projected average rates provided by CES. Changes in these rates may have an effect on the results reported in this study.

Combined alternatives show marginal savings and will likely result in longer payback on investment. The elimination of summer steam load carries a risk of developing thermal expansion challenges within the underground steam piping system. It is recommended that forensic analysis be performed on the underground piping system to determine the extent of the associated risk.

In a 2010 study, Vanderweil recommended that steam and electrical system reliability upgrades be installed:

� East Substation Expansion

� West Substation Upgrade � Steam Line Connect to Corbett � East/West Condensate Return Line � Additional Steam Reliability Upgrades

These items still apply to a CHP installation.

NOTE: The table at the end of Appendix B comparing the results of the base case and the studied alternatives assuming 1% annual growth in electricity use vs 3% used in the primary analysis highlights a potential significant positive financial impact of energy Demand side (efficiency/conservation) options that were not included in this study. i.e. From the modified table in the Summary of Results Section, 'Options with 1% Electric Growth vs Base Case with 3% growth, both with Carbon off sets - 20 year NP savings of the Base Case with 1% electric growth vs Base case with 3% growth both with or without carbon offsets is approx $19,000,000 (exclusive of capital investments) - or 20 yr NP saving of Option 3D with 1% electric growth vs the Base Case with 3% growth both with or without carbon offsets is over $54,000,000. (exclusive of capital investments) Analysis comment: Extensive efforts to reduce electrical and thermal demand could be less risky and financially compliment large supply side energy projects (studied in this report) while reducing actual carbon emissions and improving the existing physical plant of the campus. DEMAND SIDE WORK SHOULD BE SERIOUSLY CONSIDERED AS EITHER STAND ALONE SOLUTIONS OR IN COORDINATION WITH SUPPLY SIDE OPTIONS. ksd 2016-12-23
