The California ISO has moved the Summer 2023 activations for Resource Sufficiency Enhancements Phase 2 Track 1, Energy Storage Enhancements Track 1, Hybrid Resources Phase 2C - Settlements, and Ancillary Services State of Charge Constraint projects to July 1, 2023.
Due to the short development cycle for this Summer Release compared to the typical Fall Release where customers have more buffer time to make final adjustments to their systems based on final findings from market simulation, many ISO customers indicated the need for this buffer time towards the end of market simulation and the activation date of the Summer Release. The ISO understands the importance of giving our market participants this buffer time and decided to reschedule the activation date of Summer Release to July 1, 2023 due to the constraint that this release needs to be activated at the beginning of a month. The new activation date will allow market participants to finish validation of software changes, market rules, settlements statements, and make any final adjustments accordingly.
The release and project information is available in the Release User Group presentation here and on the Release Planning page here.
- Resource Sufficiency Enhancements Phase 2 Track 1 Impacted Systems: Master File, SIBR, Market, CMRI, OASIS, and Settlements
- Energy Storage Enhancements Track 1 Impacted Systems: SIBR and Market
- Hybrid Resources Phase 2C - Settlements Impacted Systems: Settlements
- Ancillary Services State of Charge Constraint Impacted Systems: Market, CMRI, and Settlements
The Summer 2023 Release functionality for Resource Sufficiency Enhancements Phase 2 Track 1, Energy Storage Enhancements Track 1, Hybrid Resources Phase 2C - Settlements, and Ancillary Services State of Charge Constraint will remain active in the current market simulation MAP Stage environment so that customers can continue to test and prepare for a July 1, 2023 activation. Customers are encouraged to contact release@caiso.com for any questions or necessary support regarding impacts of this schedule change.
