R. 21-10-002
This decision adopts local capacity requirements for 2021-2023 and flexible capacity requirements for 2021 and refines the Resource Adequacy Program.
San Diego/Imperial area local capacity requirements are trending down:
2021: 3,888 MW - 2022: 3,640 - 2023: 3,481
The reliability criteria presented in the CAISO’s Final 2021 Local Capacity Requirement Technical Study is not adopted.
A Work Group must be formed and file a report by September 1. 2020 after discussing the following:
- Local Capacity Requirement issues.
- Evaluation of the newly adopted CAISO reliability criteria in relation to the North American Electric Reliability Corporation (NERC) and Western Electricity Coordinating Council (WECC) mandatory reliability standards.
- Interpretation and implementation of CAISO’s reliability standards, mandatory NERC and WECC reliability standards, and the associated reliability benefits and costs.
- Benefits and costs of the change from the old reliability criteria “Option2/Category C” to the CAISO’s newly adopted reliability criteria;
- Potential modifications to the current Local Capacity Requirement(LCR) timeline or processes to allow for more meaningful vetting of the LCR study results.
- Inclusion of energy storage limits in the LCR report and its implications on future resource procurement
- How best to address harmonize the Commission’s and CAISO’s local resource accounting rules.
