On October 29, 2021, the California Public Utilities Commission (CPUC) issued three proposed decisions intended to address potential electric capacity shortfalls in 2022 and 2023.  The proposed decisions, if approved, would implement a variety of demand-side and supply-side policies designed to ensure that in the event of extreme weather during the summer of 2022 and/or 2023, California has sufficient electric capacity to avoid outages.

Background

In August 2020, the California ISO experienced outages during the evenings of August 14 and 15, and only extraordinary efforts, including voluntary conservation efforts by California energy users, allowed the California ISO to avoid outages the following week.

After those outages, the CPUC and the California Energy Commission (CEC) have been working towards addressing potential capacity shortfalls during extreme weather events during the summer.  In November 2020, the CPUC opened a rulemaking (R.20-11-003) to ensure reliability in the event of extreme weather during the summer of 2021.  In February 2021, the CPUC adopted a decision directing procurement of additional capacity (D.21-02-028), and in March, adopted a decision directing additional demand-side and supply-side actions to increase supply and decrease load during extreme weather events (D.21-03-056).

California managed to avoid outages during the summer of 2021, although it was helped by relatively mild weather in August and September.  A stack analysis performed by the CEC this summer, however, showed the potential for capacity shortfalls of up to 4,350 megawatts (MW) for summer 2022.  In August, the CPUC implemented a second phase to R.21-11-003, to ensure reliability during the summers of 2022 and 2023.

In docket R.20-05-003, its Integrated Resource Planning (IRP) proceeding, the California Public Utilities Commission is considering its preferred portfolio of new resources for the next ten years.  A lengthy administrative law judge ruling issued August 17, 2021 set out a suggested Preferred System Plan (PSP) for the proceeding, including a suggested resource portfolio through 2032,…

On August 19, the California Public Utilities Commission (CPUC) issued a proposed decision accepting the 2019 Renewables Portfolio Standard Procurement Plans submitted by four new Community Choice Aggregators (CCAs): Butte Choice Energy Authority; Clean Energy Alliance; the City of Santa Barbara; and San Diego Community Power.  Each of these CCAs is anticipated to start providing…

In a stakeholder call yesterday, the CAISO discussed the Revised Draft Final Proposal in the Generator Deliverability Assessment stakeholder initiative. During the call, the CAISO addressed outstanding stakeholder questions, including confirming key upcoming dates for project developers.

Background on the Proposal

The CAISO is proposing revisions to its deliverability assessment methodology in response to the rapid increase in the amount of solar resources and the California Public Utilities Commission’s (CPUC) resulting transition to an Effective Load Carrying Capability (ELCC) approach to calculating qualifying capacity (QC). The CAISO’s revisions are intended to more closely align the capacity studied in the deliverability assessment with the generator’s anticipated QC under the CPUC’s new ELCC methodology. Under the current deliverability assessment methodology, generators are studied at a higher capacity than the projects can qualify for under the ELCC methodology. Under the revised deliverability methodology, projects are expected to retain their full capacity deliverability status (FCDS) and their NQC value will not be reduced, but the proposed change should be beneficial to future interconnection customers because it will free up some unused deliverability and likely result in fewer required network upgrades to receive FCDS.

As part of the proposal the CAISO is also creating a new sub-status for solar and wind projects: Off-Peak Deliverability Status (OPDS). New solar and wind OPDS resources will receive market scheduling priority by continuing to be allowed to self-schedule as an incentive for resources to develop in locations that do not trigger upgrades or trigger only low-cost localized transmission upgrades.

On July 29, 2019, the Ninth Circuit Court of Appeals affirmed the lower court’s decision in Winding Creek Solar LLC v. Peterman et al., ruling that California’s feed-in tariff for small qualifying facilities (QFs), the Renewable Market Adjusting Tariff (ReMAT), violates the federal Public Utility Regulatory Policies Act (PURPA) (Ninth Circuit Case No. 17-17531). ReMAT provides small QFs of three megawatts (MW) or less with a standard contract for energy offtake, on a first-come, first-served basis. Under ReMAT, rates available to any given generator fluctuate based on the price the developers ahead in the contract queue will accept. The California investor-owned utilities must offer ReMAT contracts up to a program cap of 750 MW, which is proportionately split among the utilities, and then further divided across different types of generation, including baseload and peak/non-peak resources.

The Ninth Circuit ruled that ReMAT violated two tenets of PURPA. Under PURPA, subject to certain exemptions, utilities are required to buy at the avoided cost rate all the power produced by a QF. First, contrary to PURPA’s requirement that a utility buy all of a QF’s output, the Ninth Circuit found that ReMAT limits the amount of energy that utilities are required to purchase from QFs by placing caps on procurement. Second, ReMAT sets a market-based rate for energy from participating QFs, rather than a price based on the utilities’ avoided cost as required under PURPA.

On April 25, the California Public Utilities Commission (“CPUC”) adopted a decision (“Decision”) in its Integrated Resource Plan (“IRP”) proceeding, R.16-02-007.

The Decision examined the first round of integrated resource plans filed by each of the load-serving entities subject to CPUC jurisdiction. The Decision approved the plans filed by 20 load-serving entities, found that another eight load-serving entities were not required to file integrated resource plans, and found that 19 plans were insufficient as they failed to address criteria pollutant issues. One load-serving entity—Commercial Energy of California, an energy service provider—failed to file an integrated resource plan at all. The Decision also provides specific guidance for plan development for each load-serving entity for the next IRP cycle.

CPUC staff also aggregated all of the resource plans into a single portfolio—after certain adjustments to render it feasible—defined as the Hybrid Conforming Portfolio, or HCP. Adjustments were necessary to ensure that the consolidated new resource procurement proposals did not exceed resource potential in a geographic area or existing transmission availability. Commission staff identified four regions where the proposed new wind resources exceeded assumed resource potential (Northern California, Solano, Southern California Desert, and Riverside East Palm Springs). Where resource potential was exceeded, staff adjusted the resources to come from nearby regions. There were also five regions where the proposed renewable buildout appeared to exceed assumed available transmission capacity (Central Valley North Los Banos, Greater Carrizo, Southern California Desert, Northern California, and Solano). Adjustments were made in these regions by converting the proposed projects to energy-only, or moving resources to nearby locations when transmission assumptions were exceeded. No resource selections for out-of-state resources that required transmission upgrades, however, were adjusted based on transmission limitations. The Decision requires load-serving entities to disclose the contractual and development status of their resource selections in future IRPs, in order to help avoid adjustment issues in the future, and to provide an updated filing with that information to the CPUC by August 16, 2019.

The California Public Utilities Commission (“Commission”) voted recently to approve $768 million in expenditures for electric vehicle infrastructure programs proposed by the state’s three investor-owned utilities (“IOUs”). The programs are part of a directive of SB 350 that requires utilities to undertake transportation electrification activities.

Here is a brief overview of the approved programs:

  • Approved at $137 million, SDG&E’s program provides rebates to up to 60,000 residential customers that install Level 2 (“L2”) charging stations, which refer to electric vehicle supply equipment (“EVSE”) connected to a 240-volt outlet.
  • PG&E was approved for $22 million to install make-ready infrastructure to support 234 fast charging stations, as well as $236 million to support 6,500 medium- or heavy-duty EVs (like electric buses and trucks).
  • SCE similarly received approval for $343 million to install make-ready infrastructure to support 8,490 medium- or heavy-duty EVs.
  • In addition, the Commission approved $29.5 million for program evaluation.

Here is our analysis of what the Commission’s order means for the future of EVs and what the industry should be paying attention to:

In terms of charging technology, 150 kW fast charging and residential L2 are the minimum.

The Commission’s order emphasizes the need to use up-to-date technology to ensure some longevity for the investments. For example, in response to PG&E’s proposal for three levels of fast charging stations, the Commission directed the utility to forgo the lowest level and only install customer-side electric infrastructure necessary to support EVSE of 150kW or larger, approving a 25% contingency due to the increased cost of the faster chargers. Additionally, the Commission also noted that participants in rebate programs will be responsible for the full cost of proprietary made-to-order EVSE and make-ready infrastructure, since these are not scalable and may result in stranded assets should the manufacturer go out of business or change technology. In the case of SDG&E’s program, the Commission sided with the utility over concerns raised by stakeholders that Level 1 charging (which uses a standard household 120-volt outlet) is sufficient for residential purposes. SDG&E argued that the more advanced L2 will provide grid benefits by allowing for managed charging when paired with time-variable rates that reflect grid conditions. The Commission also noted the ability of these chargers to provide valuable data on patterns of charging.

Stoel Rives’ Energy Team has been monitoring and providing summaries of key energy-related bills introduced by California legislators since the beginning of the 2017-2018 legislative session. Legislators have been busy moving bills through the legislative process since reconvening from the spring recess. Below is a summary and status of bills we have been following.

An enrolled bill is one that has been through the proofreading process and is sent to the Governor to take action. A two-year bill is a bill taken out of consideration during the first year of a regular legislative session, with the intent of taking it up again during the second half of the session.

  • Since our last update, the Governor has vetoed one bill and signed the others that were sent for approval earlier this session.
  • Several bills we previously reported on have become two-year bills, but without much movement in this second half of the session.
  • Several new bills have been introduced that are currently going through the process of amendments and hearings. 

Bills Passed Since Last Update

SB 549 (Bradford, D): Public utilities: reports: moneys for maintenance, safety and reliability.
STATUS: Approved by Governor September 25, 2017.

  • Existing law places various responsibilities upon the CPUC to ensure that public utility services are provided in a manner that protects the public safety and the safety of utility employees.
    • SB 549 requires an electrical or gas corporation to annually notify the CPUC each time that capital or expense revenue authorized by the CPUC for maintenance, safety or reliability is redirected for other purposes, and requires the CPUC to make the notification available to the Office of Safety Advocate, Office of Ratepayer Advocates, and to the service list of any relevant proceeding.

On February 8, 2018, the California Public Utilities Commission (“CPUC”) adopted a new procurement process in a decision which suggested that 2,000 MW of new battery energy storage resources may be needed in California by 2030. This means an additional 2,000 MW of storage on top of the existing 1,325 MW that is already required.…

Stoel Rives’ Energy Team has been monitoring and providing summaries of key energy-related bills introduced by California legislators since the beginning of the 2017-2018 Legislative Session. Legislators have been busy moving bills through the legislative process since reconvening from the Summer Recess. For any bill not identified as a two-year bill, the deadline for each house to pass the bill and present it to the Governor for signature or veto was September 15, 2017. Below is a summary and status of bills we have been following.

An enrolled bill is one that has been through the proof-reading process and is sent to the Governor to take action. A two-year bill is a bill taken out of consideration during the first year of a regular legislative session, with the intent of taking it up again during the second half of the session.

  • Of particular note here is SB 100, California’s pitch for 100 percent renewable energy, failed to move to the next stage of the process and is kicked to next year.
  • Our next blog post, after October 15, will provide an update on whether those bills sent to Governor Brown were signed or vetoed.
