Utility Dive: The Aliso Canyon leak continues to complicate Southern California's energy situation. Risks to electric reliability because of gas storage issues are "greater in the local reliability areas of Southern California than to the rest of the CAISO system," the EIA concluded. "Operational constraints limit Aliso Canyon output, increasing ramping requirements in California."
Base case total system deliverability capacity — a combination of the pipeline system and the deliverability capacity of non-Aliso storage working gas — is slightly lower than 3.6 Bcf/d. In winter months, demand regularly exceeds that level, but it has only been hit once in the past five summers, EIA said. If that occurs, "some natural gas deliveries to electric generators may need to be curtailed."
