Phase 1 of this initiative addressed the gas-electric market coordination concerns raised by the limited operations of the Aliso Canyon gas storage facility. The resulting provisions were approved by FERC and will sunset on Nov. 30, 2016. Aliso Canyon Phase 2 will evaluate and propose to either retire, extend or adjust the interim measures approved for the summer period and will file with FERC to seek authority to retain the needed measures through the winter period. Phase 3 proposes to extend the temporary market and operational tools currently in place so that they remain in effect beyond Nov. 30, 2017. Phase 4 proposes to further extend the measures for an additional year. Phase 5 proposes to permanently retain the maximum gas burn constraint in the Southern California region.

Phase 5 of this initiative included enhancements to the existing dynamic competitive path assessment methodology employed currently in the locational market power mitigation mechanism in the day-ahead market and the real-time market.
It also included enhancements to the gas nomogram functionality to eliminate non-optimal gas burn limitation scenarios and provide flexibility for operation engineers and operators to fully assess operational conditions.
Outcome: Effective Nov 30 and Dec 16, 2018, Phase 4 extended certain interim temporary market and operations provisions to remain in effect until Dec 31, 2019.

Outcome: The ISO activated on Jun 2, 2016, two features: 1) the ability to rebid commitment costs for resources not picked up in the day ahead market, and 2) a new CMRI report showing the D+2 report was populated on Jun 5, 2016. On Jul 6, the ISO activated adjusted gas price indexes to calculate commitment and default energy bids for affected resources in the Southern California Gas Company and San Diego Gas & Electric systems, and gas price information used to increase efficiency of economic dispatch.
