California Assembly Bill 380, now Public Utilities Code § 380, requires that the California Public Utilities Commission (CPUC), in consultation with the California ISO, establish resource adequacy requirements for all load serving entities within the CPUC jurisdiction. The CPUC Energy Division administers the Resource Adequacy (RA) program, reviews all RA-related compliance filings, and advises the presiding Administrative Law Judge in ongoing RA proceedings.
The CPUC served its annual Resource Adequacy subpoena on the ISO on May 20, 2024.
The CPUC is requesting data from the ISO in thirty-five broad categories: (1) RA import allocations, (2) Supply plans filed and monthly supply plan validations for RA resources, (3) [Item left intentionally blank], (4) Economic bids and self-schedules, (5) ISO settlement quality meter data, (6) Access to the Outage Management System application, (7) Monthly Masterfile data, (8) Flexible capacity needs assessment data and allocations, (9) access to ISO Customer Interface for RA, (10) Energy management systems data, (11a) Capacity Procurement Mechanism (CPM) and Capacity Solicitation Process (CSP) results, (11b) CPM settlement data, (11c) Reliability Must Run (RMR) cost data, (12) reliability event reports sent to the Western Electricity Coordinating Council, (13) Energy market settlement data for demand response (DR) and energy storage resources, (14) CPUC jurisdictional load service entity annual and monthly deficiency notices, (15) Local capacity technical study data, (16) Local residual analysis, (17) CPM and RMR designation capacity costs and costs allocations, (18) Notices of intent to retire, mothball, or return to service, (19) CEC subpoena data, (20) RA Availability Incentive Mechanism data, (21) DR Registration System information, (22) Price taker export analysis underlying data, (23) Use limited resource information, (24) Wheeling transactions, (25) Counting firm load as contingency reserves by investor-owned utilities, (26) [Item left intentionally blank], (27) Generation resource PNODE longitude/latitude, (28) Ancillary services market settlement data for DR and Energy Storage Resources, (29) Identification of co-located energy storage and hybrid resource configurations, (30) Meter data for hybrid energy storage with a variable or intermittent component, (31) Proxy demand response commitment cost offers, (32) Data on projects in the interconnection queue, interconnection customers, deliverability allocations, and project status, (33) Path 26 historic actual flows and Path 26 total transfer capability, (34) Market bid cap data, and (35) Maximum Import Bid Price data. The CPUC requests this data to allow it to evaluate the success of the RA program on an annual basis, and to determine whether program modifications could improve the CPUC's ability to fulfill its statutory program in future program years. The 2024 schedule for data releases is located on pages 22-28 of the subpoena. The confidentiality of any data disclosed is protected by a confidentiality agreement between the ISO and the CPUC.
Any market participant that objects to the ISO producing the requested documents and information must submit its objection by noon on June 11, 2024, along with a court order or other appropriate order that prohibits disclosure in response to the subpoena. Unless the ISO receives such an order by the listed due date, the ISO will thereafter respond to the subpoena. |
