California CCAs issue request for information for long-duration storage

A group of California community choice aggregators has issued a request for information (RFI) that may inform a subsequent long-duration storage request for offers.

The RFI was issued on June 4 by the Clean Power Alliance of Southern California, CleanPowerSF, East Bay Community Energy, Marin Clean Energy, Monterey Bay Community Power, Peninsula Clean Energy, Redwood Coast Energy Authority, San Jose Clean Energy, Silicon Valley Clean Energy, Sonoma Clean Power and Valley Clean Energy.

One of the goals of the RFI is to collect information that may inform a subsequent long-duration storage RFO, which may be issued as soon as this summer by each of the CCAs individually, or some combination of the CCAs.

Another goal of the RFI is to collect information that will help the CCAs in their long-term resource planning, including identifying candidate resources for the long-duration storage need identified in a 2019-2020 reference system plan.

The CCAs noted that the RFI is open to all technologies with the potential to provide long-duration energy storage.

Specifically, eligible resources must meet the following requirements:

  • Resources must have the capability to discharge at full capacity for a minimum of 8 hours;
  • Resources must interconnect directly to the transmission or distribution system (i.e. "in front of the meter") and be able to participate directly in California Independent System Operator (CAISO) electricity markets; and
  • Resources must meet minimum California Public Utilities Commission and CAISO requirements for participation in the Resource Adequacy program.

Eligible technologies may include but are not limited to: battery storage (e.g. flow, lithium-ion), mechanical storage (e.g. pumped hydroelectric, stacked blocks, compressed air), thermal storage (e.g. cryogenic/ liquid air, molten salt), and chemical storage (e.g. hydrogen, power-to-gas).

The deadline for submissions to the RFI is July 1, 2020.

The RFI is available here.
