Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBSUMMARY

This resolution directs the five large investor-owned utilities (IOUs) operating in California to release specified data pertaining to building decarbonization within 60 days from the date the resolution is issued, and annually thereafter by September 1 of each calendar year.

The purpose of this resolution is to (a) make non-confidential data accessible to stakeholders, (b) identify continuously needed IOU data through a stakeholder process, and (c) identify common data across proceedings

In developing this resolution, Energy Division staff also identified several key issues that indirectly affect the data requirements but need to be solved first in other proceedings or venues before relevant data can be required of the IOUs. Certain complex datasets are also excluded from these data requirements because they are either already submitted by the IOUs elsewhere (e.g., rate schedules) or have little to contribute toward building decarbonization planning.

To frame the data requirements, we adopt four categories of data that the IOUs either already have or can collect. Appendix A uses these categories to formulate the required data fields, template, and format for the IOUs to fulfill.

1. Physical characteristics:i. Behind-the-meter data (e.g., onsite generation, building

type, building age, building square footage).ii. In-front-of-the-meter data (e.g., service line size, age,

locational attributes, pipeline material).

2. Energy data:i. Usage data (e.g., customer billing data, hourly load

profiles, and program-incented appliances installed on premise).

ii. Generation and distribution data (e.g. feeder capacity)

3. Rates data:i. General rate information (e.g., hourly rates by customer

class, baselines, tiers, and rate forecasts).

2

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWB

ii. Customer-specific information derived from rates (e.g., number of customers on certain rate, equity need,1 and primary heating source).

4. Customer characteristic data:i. Customer-specific information (e.g., household size,

responsiveness to programs, and other self-reported customer data collected through programs).

Each IOU shall maintain a copy of the submitted non-confidential data on a publicly accessible website and share the URL with the R.19-01-011 service list within 60 days from the date this resolution is issued. Energy Division staff is directed to post the URL for each IOU data submittal on the CPUC’s building decarbonization webpage.2

D.20-03-027 requires annual updates to the dataset if no new data submission requirements are issued. Prior year data sets shall be maintained along with the updated data, so that historical trends and changes can be studied. BACKGROUND

On March 26, 2020, the CPUC adopted Decision (D.) 20-03-027, which established the framework for two building decarbonization pilot programs: the Building Initiative for Low-Emissions Development (BUILD) program and the Technology and Equipment for Clean Heating (TECH) initiative, both authorized by Senate Bill 1477 (Stern, 2018). This resolution originates from staff’s own motion in response to Ordering Paragraph (OP) 25 of D.20-03-027.

OP 25 states:

“On September 1 of each year, each investor-owned utility shall release required data and maps needed for program planning and 1 For data requirements pertaining to this resolution, equity status of a customer may be determined based on their request or approval for enrollment in the California Alternative Rates for Energy (CARE) and Family Electric Rate Assistance (FERA) program.

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBassessment. Details and format of what will be released shall be decided through an Energy Division staff-led workshop. Based on the workshop, Energy Division staff will finalize and publish the data requirements no later than 90 days from the adoption of this decision.

A footnote to OP 25 states:

Staff may conduct future workshops to revise the requirements, provided the new requirements are published by staff no later than July 1 of each year. In the absence of any new requirements, the investor-owned utilities shall annually update the datasets based on prior year requirements. In the event of a disagreement between parties, Energy Division staff and attorneys shall be the final authority in determining confidentiality status of any required data, as governed by existing laws and regulations. Where necessary data is not readily available, the CPUC staff shall consult with all relevant stakeholders to determine how this data can best be collected and by whom. CPUC staff may require investor-owned utilities to initiate data collection through their existing processes so that it can be made available to the public in subsequent years”

On June 17, 2020, Energy Division staff led a data workshop with presentations from environmental advocacy groups, CPUC staff, and California’s five large investor-owned utilities (IOUs) focusing on the role and need of data in building decarbonization programs.3

CPUC staff presentation proposed four general data categories for stakeholder’s consideration that could be used for developing data submittal requirements for IOUs: In addition to verbal comments at the workshop, subsequent written comments were received from eight parties.

To allow the time needed to complete the resolution drafting process, and pursuant to Rule 16.6 of the CPUC’s Rules of Practice and Procedure, Energy Division staff sought an extension to the July 1 deadline to issue the data requirements. The request for extension was approved on September 1 by the CPUC’s Executive Director and Energy Division staff was given until October 3, 2020 to issue the data requirements in the form of a draft

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBresolution. This resolution provides the necessary data requirements in accordance with the revised deadline for issuance.

In conjunction with other policy issues, D.20-03-027 recognized the role of data in helping market transformation programs succeed. The decision also recognized that granular customer-level data, while useful for public interest decarbonization research, is not publicly available due to current privacy and confidentiality laws.4 Recognizing those limitations, the decision found it reasonable that customers be given the option of voluntary public donation of their energy use data for public interest research.

This resolution supports the idea that reliable market characterization data aids market development. Based on observations of other industries such as healthcare, online retail, and consumer lending, information-empowered markets and consumers self-propel to long-term change.

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBThe substance of parties’ comments is described and addressed in the sections below.

Policy Issues IdentifiedIn their comments, parties did not raise concerns about the four data categories proposed by Energy Division to formulate data submittal requirements for IOUs, but did raise various issues that are addressed below.

I. Collecting gas asset dataPG&E’s presentation at the workshop and later comments explain the complexity of how gas asset replacement is planned. They state that age alone is not a strong predictor of when distribution pipeline will be replaced and neither is remaining book value. Per PG&E, gas infrastructure does not depreciate on an asset-by-asset basis, so individual assets do not have their own depreciation schedule. Incurred capital costs are added to total costs and are recovered from customers. The retirement schedule of specific assets does not change the depreciation schedule of the gas system rate base. PG&E identified at least five variables that determine whether electrification is more feasible than gas infrastructure investments:

1) Hydraulic needs of the system2) Total estimated cost of electrification versus cost of gas project3) Meeting customer needs and reducing risk to the same or

greater extent4) All customers on the planned line accepting electrification offers5) Availability of funds

VEIC comments state that managing the impact of broad-scale electrification on the gas system is a second-order problem that should be addressed at a later stage, the focus of this stage should be addressing the first-order problem of driving customer and market adoption through TECH, and targeting specific gas lines is out of scope for TECH.

We acknowledge and agree with VEIC’s perspective that targeting specific gas lines is out of scope for TECH (and also BUILD). We also agree that TECH and BUILD’s primary goal is to develop the market for low emission technologies. But we believe that the broadest possible data access for stakeholders (within the constraints of confidentiality rules) is a key ingredient for accelerating market

6

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBtransformation. Further, the interconnected nature of CPUC proceedings compels us to consider data collection and access more broadly. For example, data submitted for IOU infrastructure approvals is done within General Rate Case (GRC) proceedings and affects rates, which directly affects market transformation.

It is not clear from VEIC comments why gas asset data would not contribute toward market transformation planning. For example, if IOUs shared plans for customer conversion at a specific line location, that information is potentially helpful to program implementers to be able to divert incentives and resources to other areas and not duplicate efforts, or conversely, extend targeted outreach and program benefits precisely to those areas in coordination with the IOUs.

In their comments on the draft resolution, EDF and the Joint Environmentals urge the CPUC to consider asking for more comprehensive gas infrastructure planning data and argued that much of this is not being collected in other proceedings. CPUC staff is open to requiring more data in next year’s resolution and will continue to monitor the Long-term Gas proceeding and the GRC proceedings to understand synergies and redundancies.

We agree with the general sentiment that gas asset replacement or extension projects involve many layers of information, planning and approval processes, and according to Joint Environmentals comments, is not comprehensively made available in GRC proceedings. As an example, the Joint Environmentals’ comments point out that SoCalGas discussion of proposed expenditures in the recent GRC proceeding was not detailed and is insufficient for gas distribution Pressure Betterment projects, Supply Line Replacements, and Main Replacements.

Considering this comment, we leave open the possibility of requiring more gas infrastructure data for public release in the 2021 resolution. Staff will also consider collecting location-specific data on degrading gas infrastructure through data requests to the IOUs and determine the extent to which this can be made public before making it an ongoing requirement under the next iteration of this resolution.

A limited information set, such as number or location of planned gas asset replacement projects, or general information regarding known

7

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBAldyl-A pipelines, is included as a starting point for building decarbonization data requirements.

Staff will also consider setting up a data working group with stakeholders and IOUS to develop future iterations of this resolution.

We also reiterate that coordinated data collection among proceedings is not scope expansion. If this were the case, it would be impossible to streamline administrative processes as each proceeding would need to have its own data resolution.

Alternatives to planned gas investment are comprehensively addressed in General Rate Case proceedings. However, limited non-confidential data related to long-term gas planning is appropriate to include in this data resolution.

II. IOU baseline territories differ from CEC climate zones The California Energy Commission (CEC) defines 16 distinct California climate zones5 that form the basis of the building energy code development work. However, California IOUs have their own climate-based zoning (23 in total)6 on which their customer energy use baselines are set. Although the CEC climate zones and IOU baseline territories are overlapping and not vastly different, the mismatch is a hinderance for cross-referencing data obtained from one system against the other.

Aligning climate zones across agencies is beyond the scope of this resolution.

While we understand it is possibly easier for the IOUs to assemble the requested data based on their baseline territories, this proceeding involves pilot programs (such as the BUILD program and the proposed WNDRR program7) that will lean on the Title 24 Building Energy Code software (CBECC-Res) for program planning and implementation. The CBECC-Res software uses CEC climate zones to model parameters such as building energy use, hourly load profiles

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBand GHG emissions. Thus, we require that the IOUs use the CEC climate zones to submit the required data.

In its comments on the draft resolution, SDG&E cautions against the use of data collected in these categories (aggregated by CEC climate zones) to inform future proposals or recommendations related to electric baseline allowance, unless and until the data provided here is appropriately re-aligned with utility baseline usage quantities. We note this caution and agree that a realignment or calibration would be necessary to use this data for CPUC policies related to electric baseline allowance. However, for immediate use by the CEC for administering the BUILD program, alignment with CEC climate zones is appropriate.

CEC climate zones and IOU baseline territories are similar, but not fully aligned. Programs in this proceeding will need to use the CEC’s CBECC-Res software to comply with the building energy code. Therefore, requiring data from IOUs aggregated by CEC's climate zones will enable an ‘apples to apples’ comparison.

III. 10-year gas service agreements between the IOUs and their customers cannot be modified without CPUC approval

PG&E’s comments reiterated an important issue raised by stakeholders at the June 17, 2020 workshop. Per PG&E’s comments, when gas service is first provided, a customer signs a 10-year service agreement with the gas company, this 10-year term has been established by CPUC. If the customer wishes to electrify before the 10-year period, the cost of infrastructure removal largely falls upon the customer, which becomes a barrier to electrification. CPUC staff is looking into this issue, and it may be addressed in a later phase of this proceeding or in another proceeding.

In terms of relevance of this issue to data, PG&E explains that year of installation provides a good proxy to ascertain whether certain localities are past the 10-year service agreement mark, and can be therefore candidates for early electrification. Not only for identifying communities suitable for early electrification, we note that maps showing age of households (using meter installation date as a proxy) is a valuable data set by itself, as age of a dwelling can be a predictor of many other coincidental factors such as insulation levels (based on

9

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBprevalent energy code, electrical panel size (based on prevalent electrical code), and presence of asbestos, etc. We also note that age of building is not considered confidential.

In this year’s data resolution, we are not requiring year of installation data mapped to each service address, but instead as a less comprehensive customer characterization matrix shown in Appendix A. However, we do signal the need for this data in map form so that IOUs can start assembling it for 2021 data submittal.

SoCalGas comments seek clarification on whether the utilities should provide the original meter installation date or the most recent meter replacement dates if a meter was replaced.8 Given that the objective of this requirement is to use the date of meter installation as a proxy for construction year, we clarify that the date of original meter installation should be used.

Date of original meter installation is a reasonable proxy to ascertain the age of a dwelling and is non-confidential data.

IV. Customer data access is difficult for a contractor, even after customer permissions

According to CALSSA, the Green Button9 portal available through IOU websites is frequently out of service, making it difficult to get interval data for the customer. Per CALSSA, efforts to get this data through e-mails to utilities even after customer authorization can take as long as 30 days. Solar and storage contractors need a simpler process for one-time download that does not require sophisticated contractor websites to connect with Green Button in the back end. Further, SCE comments highlight the lack of Green Button-enabled data access for gas customers. We acknowledge the importance of access to individual customer’s energy data to third party service providers. This issue is already being addressed in the click-through authorization proceeding.

8 SoCalGas comments to draft Resolution E-5105, pg. 2.

9 Green Button is a voluntary data access initiative and standard launched by the White House in 2011 and adopted by most California IOUs. It allows utility customers the ability to download their detailed energy use data by clicking on a “green button” from within their online customer dashboard on the utility website.

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBThe click-through authorization process for customers to approve the provision of the customer’s specific information to third party providers is being addressed in CPUC’s proceeding A.18-11-015.

V. Public Disclosure of Hourly Energy Use DataStaff presentation gave an overview of the data access rules established by D.14-05-041. In discussions following the workshop, Recurve Analytics raised the issue of unavailability of hourly energy use data for public use.

Staff recognizes that building decarbonization’s most obvious “Achilles heel,” as well as its biggest opportunity, is in balancing the electric grid through load management. Maximizing the use of generation from renewables in the daytime and shifting peak loads to the greatest extent possible is necessary in both demand side and supply side markets. To enable Distributed Energy Resource (DER) markets, Recurve Analytics argues that it is crucial that the markets have access to data at a level of granularity that influences decision-making. More specifically, hourly energy use data, which the IOUs collect from each customer account through ratepayer-funded smart meters, remains underutilized for spurring market competition, even as we face rolling blackouts and see demand remain stubbornly high during peak hours.

Locationally and temporally granular data need not compromise customer confidentiality. Past CPUC decisions guard customer privacy and prevent any level of anonymized or aggregated customer hourly interval data to be available for public disclosure. CPUC’s Energy Data Access decision- D.14-05-016- meant to provide the benefit of rich, smart meter-enabled data to various stakeholders, but it did not define aggregation thresholds10 for hourly interval data. Instead it defined them for monthly energy use data.11 D.14-05-016 also predates Assembly Bill 802 (Williams, 2015), which defined less conservative aggregation thresholds for customer data access for both residential and non-residential customers.

10 Aggregation threshold is the degree to which data is summed or aggregated- across customers (combining data from more than one customer), across time (combining data across more than one time period), or a combination of both.

It is beyond the scope of this resolution to take up this issue.

VI. Coordination with other ProceedingsBoth staff and SDG&E’s presentation mentioned a previous decision from the energy efficiency proceeding (D.18-05-041) which requires SCE as the lead IOU to establish a statewide energy use data analytics and mapping tool to enable data access for the public and local governments. The decision directs the IOUs to assign up to $2 million within their energy efficiency portfolio budgets to fund the tool.12 Multiple parties also mentioned in verbal comments at the workshop the complementary value of such a tool to the data requirements of this resolution.

Staff acknowledges that the market characterization data envisioned to be collected through this resolution would benefit many other proceedings since all proceedings are aligned to statewide DER goals. Conversely, as more sophisticated energy data access tools, such as the one required by D.18-05-041 are developed, IOUs can streamline this resolution’s data submittal requirements through them.

Future energy data access tools currently under development in other proceedings may alleviate data reporting requirements of this resolution. VII. Clarifications and Additional Data RequirementsThe Joint Environmentals' comments request that IOUs provide additional information under a number of categories. Some of the suggested information is broad- such as "all information available on emission rates of gas facilities and gas combustion indoors." The comment then states that this could include any source tests or other data that the IOU has conducted or has access to. A stakeholder or staff-led working group is the appropriate venue to discuss these issues in necessary detail to develop future iterations of this resolution.

Similarly, the Joint Environmentals' comments seek data for 'gas leakage from gas facilities.' We decline to include this data in Appendix A as the annual report on natural gas leaks and emissions 12 2018 Energy Efficiency Business Plan Decision D.18-05-041. OP 32, pg. 189. https://docs.cpuc.ca.gov/PublishedDocs/Published/G000/M215/K706/215706139.PDF

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBproduced by the CPUC (R.15-01-008/D.17-06-015)13 and the California Air Resources Board, in compliance with SB 1371, provides emissions data on utility transmission, distribution and storage systems and discusses emissions by system categories, source categories and leak grades.

The Joint Environmentals' comments place further emphasis on the need to understand energy burden in low income households. Specifically, they ask to collect information regarding bill fluctuations during heat waves. Staff has modified Appendix A to require additional data on highest average customer bills in a single billing period.

EDF is concerned that the cost information – including depreciation schedule, remaining book value and other financial metrics, are not granular enough to give the Commission a robust decision making tool, and urges staff to revise the draft resolution to include more masked and aggregated financial information.However, we see little relevance of granular information related to gas system at this stage, as the goal of the pilot programs is market development for low emission technologies. But we do see the importance of this data for long-term gas planning and targeted electrification in future programs. Through confidential data requests, CPUC staff may collect such data and determine a non-confidential subset of data that can be released publicly as the pilot programs mature and are scaled for targeted electrification.

Similarly, we take note of EDF’s comments to (confidentially) collect customer-specific data to ‘mark’ where recent gas efficiency programs/low income efficiency replacements have occurred and not prematurely remove these upgrades to switch to electrification. CPUC staff can request prior program participant data from the IOUs outside of this resolution process and provide to the TECH implementer under contractor non-disclosure agreements.

SCE comments requested a clarification of the ‘number of customers’ data category in Appendix A. Instructions within Appendix A have been updated to clarify that a distinct service account shall count as a ‘customer.’

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBSCE stated that it has more than 100 domestic rate codes, and not all of them would be relevant for decarbonization research in the current format. Instructions for rate schedule in Appendix A have been updated to clarify that utilities with more than 20 currently prevalent rate schedules, may choose to not include rate schedules with less than 5% enrolled customers.

SDG&E seeks clarification on data aggregation to maintain previously established confidentiality protocols. We reiterate that all previous confidentiality rules and protocols established by the CPUC are applicable. Instructions in Appendix A have been updated to clarify that only data that the IOU deems to be confidential shall be submitted to the CPUC via secure FTP server. CPUC staff and attorneys shall make the final determination on the confidentiality of the data.

PG&E and SDG&E recommend that customers with less than a full year of service on a single rate be excluded from calculations of average annual bills. Instructions in Appendix A have been modified to reflect this recommendation.

SoCalGas’ comments expressed concern regarding assumptions related to ‘Dual Fuel’ and ‘Gas Only’ customers. Specifically, ‘Gas Only’ customers should not be construed as customers only receiving gas and no electric service. Their comments also recommend that ‘Dual Fuel’ should be changed to ‘Natural Gas Space and Water Heating.’ However, we note that an IOU may not know for each customer whether their specific equipment is gas or electric. But an IOU that supplies both gas and electric service to a customer can accurately regard that customer as ‘Dual Fuel.’

Further, electric space heating is potentially determined by filtering customers’ bills with a ‘all electric’ baseline adjustment as required by PU code section 739(a)(2)(b). We note that while section 739(a)(2)(b) defines electric space heating as eligible for “all-electric” baseline, customers on this baseline are not necessarily single fuel (electric only) customers, as they may have a gas water heater.

To account for these concerns, definitions for ‘Dual Fuel,’ ‘Electric only/ Gas’ and ‘all electric baseline’ have been added and/or modified in Appendix A. ‘Electric Space Heating’ has been removed from fuel-based reporting columns and instead added as a separated category

14

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBwithin the row of rates (“All-electric” baseline), as the baseline can apply to multiple rates.

PG&E and SoCalGas both recommended that the data should be a snapshot in time as the data can change throughout the year. Instructions in Appendix A have been modified to ‘as on December 31 of reporting year’ where relevant.

SoCalGas seeks clarification on what construes a ‘planned’ gas project as required in the Gas Infrastructure worksheet. We modify this requirement to correspond with the latest General Rate Case required replacements, or other CPUC-approved programs and plans (which differ by IOU), such as the Gas Pipeline Replacement Program, the Public Safety Enhancement Plan etc. Appendix A has been modified to reflect this change. We also modify leakage reporting requirement to be more reflective of how these leakages are detected as opposed to customer class.

PG&E points to the frequent occurrence of customers changing rate schedules during the year. It is useful to understand if customers are favoring a particular rate, or more likely to change from a specific rate, especially when reviewed year over year. We have added this requirement in Appendix A (matrix for number of customers who changed from one rate schedule to another).

Guidance for the BUILD Program and TECH Initiative evaluatorI. Program metrics should consider both 2030 and 2050

goalsSCE in its comments outlines many statutes, proceedings, decisions, and regulatory work, some even outside of CPUC, that currently shape California’s building decarbonization policies. Each of these is informed by data in some form, and we acknowledge that there are many overlaps in terms of required data and that some of it is not necessarily collected by the IOUs, which is the focus of this resolution.

SCE recommends that any data metrics for building decarbonization keep both 2030 and 2050 targets in mind, specifically while assessing system costs. While some of the ‘least-cost’ system analysis will be outside the scope of this proceeding, we recommend that the program evaluator who will be evaluating both the BUID Program and the

15

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBTECH Initiative pursuant to the requirements outlined in D.20-03-027 consider short-, mid-, and long-term building decarbonization goals for setting program metrics. The program evaluator should consider statewide short-, mid-, and long-term building decarbonization goals for setting program metrics.

II. Data on barriers to electrification, customer health and safety, and community resilience

The Joint Environmentals emphasize equity considerations, including language barriers, customer health and safety, and community resilience for program planning and assessment. Program metrics would be developed by the BUILD and TECH program evaluator. Once the program evaluator is on board, Energy Division staff can issue data requests to develop and evaluate these metrics. The process of shaping those metrics is not part of this resolution and will be led by the evaluator. However, we identify certain related data (such as number of reported gas leaks by customer class, by climate zone) to provide some initial data to stakeholders and enable deeper inquiries into the co-relation between electrification, customer health and safety, and community resilience.

We request stakeholders to identify specific data fields related to electrification barriers, customer health and safety, and community resilience that they believe are available from the IOUs. Energy Division staff will revise the requirements based on comments received.

Data Requirements for IOUsI. Non-confidential Data

Energy Division staff compiled a matrix of data requirements (Appendix A) derived from prior staff data requests sent to the IOUs and stakeholder comments received in response to the June 17 workshop. The data submittal requirements are structured around the four data categories that were shared in the staff workshop. These are: (1) Physical characteristics (2) Energy data (3) Rates data and, (4) Customer characteristic data. Parties did not raise any objections to the data categories, and therefore we consider them reasonable for formulating the data submittal requirements at least for the first year.

16

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBConsiderations for Data Requirements:Understanding stakeholder needs in conjunction with what is available, or can be made available, by the IOUs is an iterative process. OP 25 of D.20-03-027 allows Energy Division staff to issue the data resolution annually, which enables the opportunity to build upon these initial data requirements.

We limit the extent of data requirements for this first data resolution based on our understanding of what will immediately be helpful for enabling market transformation and program planning. This will also limit the burden and associated costs to the IOUs and, consequently, ratepayers. For example, we are not requiring map-based data showing age of structure associated with the service account (using year of original meter installation as a proxy). We are also not requiring any prior program impact or participation data such as from energy efficiency, self-generation incentive, solar, Electric Vehicle (EV) charging or other DER programs. Additionally, at this time we are not requiring any data related to square footage of structures, although previous proceedings have required IOUs to report metrics based on square footage.14 For future requirements we anticipate, for instance, that maps showing areas by service line size could be helpful (as not all capacities are easily able to support additional electrical loads, and other amperage management strategies become necessary).

To the extent possible, we have tried to formulate the data submittal requirements for this year to be based on IOU billing databases.

Since BUILD and TECH programs have not launched yet, program assessment data cannot be included. Also, individual participant data is most valuable for evaluations. It can generally not be shared due to confidentiality restrictions unless the customer has agreed to share their data for public use.

All required data is for residential sector only, except for natural gas infrastructure data, which is expected to cover all sectors due to its nature. Unless otherwise specified, data is required to be aggregated to CEC climate zones falling within each IOU territory, so that aggregation thresholds set my previous proceedings are duly met.15

14 Ibid. D.18-05-041 requires IOUs to report several portfolio metrics, including energy savings per square foot in both single family and multifamily sectors. A, pg. A2-A3.

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBAppendix A provides the spreadsheet template for submittal of non-confidential data.

Number of Customers by Rate ScheduleThe first tab asks for the number of single family and multifamily customers by rate schedule, and current delivered fuel type. The purpose of this tab is to understand residential market size, current preferred rate choices, and prevalence of onsite generation and storage. In response to NRDC comments, we also ask for number of master-metered customers to develop a shared understanding of the prevalence of such accounts.

The same information is requested for customers on California Alternative Rates for Energy (CARE) as a means of characterizing low-income customers. We understand that not all low-income customers are on CARE, but this seems to be the most straightforward way to understand this demographic through existing IOU billing databases.

Finally, we believe it is important to understand how many customers are in need of medical baseline and are more vulnerable during times of power shut-offs. Even though climate zone level data will not help with targeted customer outreach, it will help us understand the minimum scale at which resiliency efforts are needed.

Customer Bills as a Function of RateCustomer rates are expected to have a strong impact on the market for electrification. The second tab asks for average customer bills by rate schedule, for single family and multifamily customers and their current delivered fuel type. The purpose of this tab is to understand whether particular rates are especially unfavorable towards electrification, or appear to be so, and warrant further inquiry.

Average bills and number of customers by climate zone from the previous tab can also be used to compute sum total of bills for a climate zone. This can help understand which climate zones currently bear the highest bills per household. In conjunction with census data (not part of IOU data requirements), such as income and household size, this data could shed light on equity needs and energy burden in specific climate zones.

18

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBCustomer Energy Use as a Function of RateCustomer bills (required in the previous tab) may or may not be an accurate predictor of customer energy use. So, looking at average customer energy use as a function of rates is also necessary. For example, this data could shed light on the overall impact of time of use rates on energy use.

Median energy use, as opposed to average, may also be useful, as outliers can skew the mean. We propose to limit it to one statistic this year, but will consider stakeholder comments as to whether other statistics may be better. Energy Use as a Function of Dwelling Age The energy use tab asks for number of customers and energy use data as a function of age of dwelling. Year of meter installation is assumed to be a proxy for the construction year.

Older dwellings tend to be less energy efficient, as stricter building energy code over time likely means that dwellings have better thermal envelope (notwithstanding code compliance issues).

There are a number of ways this data would inform policy and stakeholders. For example, electrifying leaky, higher energy use structures of certain vintages in pre-dominantly low-income climate zones could increase their energy burden, and energy efficiency upgrades may be needed first. Understanding how many households have undergone comprehensive upgrades through programs like the Energy Savings Assistance Program will provide clues to their readiness for electrification by distinguishing between energy efficient structures and others that might be more likely to result in wasted energy.

Gas Infrastructure DataAs explained under Policy issues, Section IV, we propose collecting only certain limited data related to gas infrastructure. Tab 5 in Appendix A requires IOUs to submit high-level information related to planned infrastructure development, presence of Aldyl-A pipes and number of reported gas leaks. Detailed information by project is not being sought in this proceeding.

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBII. Confidential DataThis resolution does not provide requirements for confidential data, that typically contain specifications for individual customer information, for the following reasons:

1) The obligation to preserve customer privacy means that such confidential data can only be released to certain entities under specific situations (e.g., to CPUC or CEC staff, or their consultants under specific non-disclosure agreements, or to IOU consultants under specific agreements), and cannot be made part of the public process.

2) Once the program evaluator for BUILD and TECH is under contract, that entity will likely have its own data needs based on its evaluation plan. These data needs can be facilitated by Energy Division staff through data requests to the IOUs at the necessary time.

3) Stakeholders have not expressed interest regarding what kind of data the CPUC or its consultants routinely request or intend to request.

4) As programs launch, program implementers could provide the option of voluntary public donation of energy use data to participating customers, in line with the findings and conclusions of D.20-03-027. For customers who agree to make their data non-confidential, their energy use data can be included in future data requirements.

III. Data FormatIOUs shall provide the required data in a Comma Separated Value (.csv) format using the template provided with this resolution in Appendix A.

We acknowledge that this format is not ideal for customizable queries. Setting pre-assigned two-dimensional parameters, such as energy use as a function of rates, limit the ways in which market characteristics can be visualized. Ideally, an interactive, user-friendly tool would allow various information sets to be analyzed against each other, and across time.

However, as mentioned in Section VI under policy issues, we believe that the statewide energy data analytics tool required by D.18-05-041 can be designed to achieve this functionality when it is operational, and could incorporate future data requirements of this proceeding

20

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBwithout need for additional funding. Therefore, we find it unreasonable, at present, to require IOUs to spend resources for a more sophisticated data dissemination method.

IV. Data Submittal ProcedureEach IOU shall publish the required data on a publicly accessible website and share the URL with the R.19-01-011 service list within 60 days from the date this resolution is issued. Energy Division staff are

21

D.20-03-027 requires annual updates to the dataset if no new data submission requirements are issued. IOUs shall maintain prior year data sets with the updated data, so that historical trends and changes can be studied. In future years, if more sophisticated energy data analysis tools required by other proceedings are developed, IOUs may choose to use them or point to them to fulfil these data submittal requirements, provided that the required data is accessible to the public.

COMMENTS

Public Utilities Code section 311(g)(1) provides that this resolution must be served on all parties and subject to at least 30 days public review. Please note that comments are due 20 days from the mailing date of this resolution. Section 311(g)(2) provides that this 30-day review period and 20-day comment period may be reduced or waived upon the stipulation of all parties in the proceeding.

The 30-day review and 20-day comment period for the draft of this resolution was neither waived nor reduced. Accordingly, this draft resolution was mailed to parties for comments on October 5, 2020, and placed on the Commission's December 3, 2020 meeting agenda.

Six written comments were received from the following parties in response to the draft resolution:

1. Environmental Defense Fund (“EDF”)2. Sierra Club, California Environmental Justice Alliance, and

Natural Resources Defense Council (“The Joint Environmentals”)3. Pacific Gas and Electric Company (“PG&E)4. Southern California Edison Company (“SCE”)5. San Diego Gas and Electric Company (SDG&E”)6. Southern California Gas Company (“SoCalGas”)

The majority of the comments received have been addressed in this final resolution where a clear rationale was provided or where reasonable clarification was sought. These have been laid out and explained in the appropriate Discussion section.

Resolution E-5105/ R.19-01-011 December 3, 2020PG&E, SDG&E, SCE, SoCalGas, SWGas/AWBFINDINGS

1. D.20-03-027 directed Energy Division staff to issue data requirements for the California investor-owned utilities to inform program planning and assessment. A staff workshop was held on June 17, 2020 to gather stakeholder feedback for framing the data requirements.

2. Alternatives to planned gas investment are comprehensively addressed in General Rate Case proceedings. Certain non-confidential data related to long-term gas planning is appropriate to include in this data resolution.

3. CEC climate zones and IOU baseline territories are similar but not fully aligned. Programs in this proceeding will need to use the CEC’s CBECC-Res software for program planning and implementation.

4. Date of meter installation is a reasonable proxy to ascertain the age of a dwelling and is non-confidential data.

5. Current CPUC rules do not allow public disclosure of anonymized or aggregated hourly customer energy use data.

6. The data submittal requirements, submittal procedure and format set forth in this resolution are reasonable.

THEREFORE IT IS ORDERED THAT:

1) Pacific Gas and Electric Company, San Diego Gas & Electric Company, Southern California Edison, Southwest Gas Corporation, and Southern California Gas Company are hereby ordered to provide the non-confidential data required in Appendix A within 60 days of the date that this resolution is issued, and annually thereafter by September 1 of each calendar year.

2) Energy Division staff may revise the data requirements through another resolution which shall be issued no later than July 1 every year.

3) Each IOU is directed to maintain a copy of the non-confidential data required by this resolution on a publicly accessible website and share the URL with the R.19-01-011 service list.

4) Energy Division staff are directed to post the URL for each IOU data submittal on the Commission’s building decarbonization

“Instructions” Worksheet

Instructions and Definitions Average Customer Annual Bills and Energy Usage

To calculate average annual bills and average annual energy usage, please exclude customers with less than a full year of service at a given rate to avoid biasing the averages.

"All-electric" baseline

Customer accounts that are on the "all-electric" baseline as defined by PU code section 739(a)(2)(b)- “all-electric residential customers” are residential customers having electrical service only or whose space heating is provided by electricity, or both [gas and electric].Because of this statutory definition, customers on "all-electric" baseline may not necessarily be electric-only customers. To distinguish the two, the column 'Electric-only' will be used to report customers who do NOT have natural gas service from a utility.

Confidential DataAny data that the IOU considers to be confidential shall be submitted to CPUC staff via secure FTP server. All existing confidentiality rules continue to apply. CPUC staff and attorneys shall make the final determination on the confidentiality of the data.

Customer

For data reporting, a distinct service account counts as a customer. Please report customer counts and corresponding energy usage in each rate schedule as on December 31 of the reporting year, so as to avoid excluding customers who change rates during the year or move within the service territory.

CZ Climate Zone: Each IOU shall report for each CZ within their territory. Please use CEC Climate zones

Dual FuelCustomer account where natural gas is used for both space heating and water heating there is an active electric and natural gas service by the same utility on December 31 of reporting year (e.g. customers served both gas and electric service by PG&E)

All-Electric Only/Gas OnlySingle fuel utilities will mark 'NA' in the cells for which they have no information. For e.g. SoCalGas will only report on its (gas) customers and will have no data to report for Electric Only customers

HERS Registry Data We understand that this is a purchased data set through CalCerts. Territory level data can be made public, Climate zone data is not public. 15 D.14-05-106 requires an aggregation threshold of 100 residential customers per zip code (pg. 26). Climate zones are larger than zip codes. However, if the threshold of 100 customers (service accounts) is not met, IOUs should not report a value for that data field and instead mark it as “Aggregation threshold not met”

Instructions and Definitions SCE has already obtained this data for 2013 and 2016 code cycles for all IOUs (except SW Gas). If you don’t already have this data from SCE, please contact CPUC staff ([email protected]). If you have purchased 2019 code cycle data, or plan to, please let your counterparts in other IOUs know so they are not purchasing it again.

Highest Average Customer Bills

Choose the billing period when average customer bills within a climate zone were the highest. For e.g. Average bill for the billing period with the highest number of extreme weather days as currently defined by the IOU ('Flex alert,' 'Smart Days'). The intent is to understand customer energy burden due to fluctuations in energy bills.

Multifamily Multifamily is defined as at least two residential housing units

Rate Schedules/tariffs

Utilities with more than 20 currently prevalent rate schedules may choose to not include rate schedules with less than 5% enrolled customers. Please footnote the weblink for the latest rate schedules. E.g. PG&E E-6: {http://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_E-6.pdf}

Reporting YearWhere annual data is required, please use calendar year 2019. For future updates, please use last completed calendar year (Jan 1-Dec 31). Please also see instructions for 'Customer.'

Structure Age/ Construction Year

Date of Original Meter Installation may be used as a proxy for year of construction. Additions to a service address when no new utility connection was requested can be ignored. Aggregating service address to a structure is not required. For simplicity, service address will be considered synonymous to structure.

Solar PV Customers Include virtual net energy metering or net energy metering aggregation customers
