CAISO has proposed to make permanent its practice of curtailing gas burn and using market tools to reduce the reliability risk posed by Aliso Canyon.

The continued closure of the Aliso Canyon natural gas storage facility remains an issue for the summer readiness of the Southern California grid.

CAISO experienced its first “Stage 1” grid emergency in nearly a decade, days after Southern California Gas' warning about Aliso Canyon.

CAISO said it will take advantage of a recently approved system reliability measure when Aliso Canyon gas pipeline restrictions constrain output.

FERC approved the CAISO plan to extend the temporary Tariff provisions the ISO implemented after last year’s closure of Aliso Canyon.

Actions taken in the wake of the closure of the San Onofre nuclear plant ultimately helped California address the Aliso Canyon shut down.

FERC approved the CAISO natural gas price index used in response to the closure of the Aliso Canyon storage facility.

RTOs told FERC they are confident they will maintain reliability this winter, citing improvements in gas-electric coordination and monitoring tools.

CAISO's board has approved a proposal to extend Tariff provisions implemented in June in response to the closure of the Aliso Canyon storage facility.

Winter grid operations in Southern California are unlikely to be compromised by natural gas pipeline restrictions due to the shutdown of Aliso Canyon.
