2. Renewable Generation Plus Storage Contracts: RPS-eligible generation (15 MW – 150 MW¹) paired with storage projects (15 MW – 150 MW¹). The storage duration must be at least 4 hours and the capacity cannot exceed 100% of the generation nameplate capacity. Projects in this category must have a commercial operation date no later than December 31, 2033. PPA tenor must be between 10 and 20 years.

• Renewable Generation can be paired with CPUC Decision D.26-02-057 Eligible Long Duration Energy Storage (LDES) with a storage capacity of 15 MW – 100 MW¹. The storage duration must be at least 8 hours, and the capacity cannot exceed 100% of the generation nameplate capacity. Projects in this category should have a CTSD between January 1, 2029 and June 1, 2032. Contract tenor must be between 10 and 20 years.

3. RPS Generation + Storage (CPA Resource): RPS generation paired with storage where one component is a resource under contract with CPA.

• Option 1: Add energy storage to a CPA standalone RPS generation facility.
  • The storage duration must be at least 4 hours, and the storage power capacity cannot exceed 100% of the generation nameplate capacity. The minimum system size requirement is 15 MW¹ and the maximum size must not exceed the existing capacity at the point of interconnection. Projects in this category must have a CTSD between January 1, 2029, and December 31, 2033. Contract tenor must be between 10 and 20 years.
  • Decision D.26-02-057 Eligible LDES. The storage duration must be at least 8 hours, and the storage capacity cannot exceed 100% of the generation nameplate capacity.  The minimum system size requirement is 15 MW¹ and the maximum size must not exceed the existing capacity at the point of interconnection or 100 MW. Projects in this category should have a CTSD between January 1, 2029 and June 1, 2032. Contract tenor must be between 10 and 20 years.
• Option 2: Add an RPS generation resource to a CPA standalone energy storage project.
  • RPS-eligible generation (e.g. solar, wind, geothermal). The capacity cannot exceed 100% of the storage nameplate capacity. The minimum system size requirement is 15 MW¹ and the maximum size must not exceed the existing capacity at the point of interconnection. Projects in this category must have a CTSD between January 1, 2029 and December 31, 2033. Contract tenor must be between 10 and 20 years.

4. Standalone Storage Contracts: Standalone storage projects with a storage capacity of 15 MW – 150 MW¹. The storage duration must be for at least 4 hours. Projects in this category must have a commercial operation date no later than December 31, 2033. PPA tenor must be between 10 and 20 years.

• CPUC Decision D.26-02-057 Eligible LDES: Standalone storage with a capacity of 15 MW¹ – 100 MW and a duration of at least 8 hours. Projects in this category should have a CTSD between January 1, 2029 and June 1, 2032. Contract tenor must be between 10 and 20 years.

5. RA Only Contracts: RA-only projects from storage, thermals, or other qualifying resources with a capacity between 15 MW – 150 MW¹. Projects in this category must have a commercial operation date no later than December 31, 2033. PPA tenor must be between 5 and 15 years.

6. PCC1 Energy Only (fixed price or index plus) Contracts: RPS-eligible generation (e.g. solar, wind, geothermal), 15 MW – 150 MW¹ in size, offered as PCC1 Energy Only fixed price or index+ contracts. Projects in this category must have a commercial operation date no later than December 31, 2033. PPA tenor must be between 5 and 20 years.

7. Dispatchable Thermal Energy with RA Contracts:

• • Existing Dispatchable Gas projects (with RA) paired with storage: These may include gas fired generation resources such as CC, CT, RICE, CHP, or ST projects that are paired with storage (minimum 1 hour) in order to reduce greenhouse gas and emissions that impact local air quality. The project size must be at least 10 MW with a CTSD no later than December 31, 2033. The PPA tolling tenor must be between 2 and 10 years.

• • Existing Dispatchable Gas projects (with RA) running on blended fuels: These may include gas fired generation resources such as CC, CT, RICE, CHP, or ST projects that use a green hydrogen or renewable biogas blend in order to reduce greenhouse gas emissions. The project size must be at least 10 MW with a CTSD between January 1, 2029, and December 31, 2033. The Contract tolling tenor must be between 2 and 10 years.

1 CPA will consider contracting with projects smaller than the minimum size referenced above if they are located within CPA’s service area (Los Angeles or Ventura Counties). The minimum system size for individual locally sited renewable generation and/or energy storage projects must be at least 5 MW. CPA will not accept the aggregation of multiple projects to achieve the minimum size requirement.
