On May 20, 2022, the California Public Utilities Commission (CPUC or Commission) issued a proposed decision (PD) that would, among other things, adopt Southern California Edison’s (SCE) 24-hour-slice proposal as the new resource adequacy (RA) framework applicable to load-serving entities (LSEs) under the CPUC’s jurisdiction.  Generally, the proposal would require each LSE to show that it has enough capacity to meet its specific gross-load profile, including a planning-reserve margin, or PRM, for all 24 hours for the “worst day” of each month.  The “worst day” would be defined as the day of the month that has the highest coincident-peak-load forecast.  This new RA framework would likely be implemented in 2025, with 2024 serving as a “test year” for the new framework.

The Commission initially began examining potential changes to its RA framework due to significant and ongoing changes in California’s generation-resource mix, with the increasing reliance on variable resources such as solar and wind, and use-limited resources, such as energy storage and demand response, as well as the retirement of older natural gas generation.  The Commission solicited proposals for a new RA framework starting in 2020, and in 2021 it tentatively adopted Pacific Gas and Electric’s (PG&E) slice-of-day proposal in decision 21-07-014.  The Commission ordered a series of workshops to further develop the proposal, culminating in a workshop report submitted March 1, 2022.  During the workshops, two alternate proposals were developed:  SCE’s 24-hour-slice proposal, and a two-slice proposal developed by Gridwell Consulting.  The parties generally favored one of the two alternate proposals, rather than the PG&E slice-of-day proposal.  The selection of SCE’s 24-hour-slice proposal will set the direction for further development of the new RA framework.

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 June 2021, the California Public Utilities Commission (Commission) issued its Mid-Term Reliability Procurement Decision, Decision (D.) 21-06-035, which directed load-serving entities subject to its jurisdiction (investor-owned utilities, community choice aggregators, and energy service providers) to procure at least 11,500 megawatts (MW) of net-qualifying capacity (NQC) for reliability for the period 2023 through 2026.  The decision established cumulative annual procurement requirements: 2,000 MW in 2023, 6,000 MW in 2024, 1,500 MW in 2025, and 2,000 in 2026.  The decision also states that the Commission expects all of the resources procured pursuant to that decision to be zero-emitting, unless they otherwise qualify under renewables portfolio standard eligibility requirements (biomass, for example).

The California Energy Commission (CEC) has continued its efforts to implement Governor Newsom’s July 30, 2021 Emergency Proclamation, which was intended to free up energy supply to meet demand during extreme heat events and wildfires, and to expedite the deployment of additional generation.

The Emergency Proclamation authorized the CEC, which is responsible for licensing thermal powerplants of 50 megawatts (MW) or more, to also license new, or expansions of, battery storage systems of 20 MW or more that are capable of discharging for at least two hours and will deliver net peak energy by October 31, 2022.

In February 2018, as part of its efforts to remove barriers for electric storage resources, the Federal Energy Regulatory Commission (FERC) issued its final rule on electric storage participation in organized markets (Order No. 841).  Order No. 841 directed Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) to revise their tariffs to establish a…

The New Jersey legislature recently passed a bill (the “Bill”) that would set a goal of reaching 600 megawatts of energy storage capacity by 2021 and 2 gigawatts by 2030.[1] This represents one of the largest energy storage implementation goals in the country and likely signals the coming of a large new market for…

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.

Massachusetts recently became the latest state to adopt an energy storage target, following California’s lead, and recent storage legislation in Nevada and New York.

The Massachusetts storage mandate originated in the legislature last year, when the state legislature passed H.4568, which was signed by the Governor on August 8, 2016. The legislation required the state’s…
