Aliso Canyon gas-electric coordination
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.
