Electrical System Reliability Needs of the South Coast Air Basin (AB 1318)
This page last reviewed on September 26, 2011
Assembly Bill 1318 (AB 1318, Perez, Chapter 285, Statutes of 2009) requires the Air Resources Board, in consultation with the California Energy Commission (CEC), California Public Utilities Commission (CPUC), California Independent System Operator (CAISO), and the State Water Resources Control Board, to prepare a report for the Governor and Legislature that evaluates the electrical system reliability needs of the South Coast Air Basin (SCAB) and recommends the most effective and efficient means of meeting those needs while ensuring compliance with State and federal law.
September 2011 Progress Update:
The CAISO, CEC, and CPUC are currently working on the study scenarios needed to determine long-term fossil capacity requirements for the South Coast Air Basin. Their analytic approach is using power flow models to determine thermal violations and transient and post-transient stability analyses. Minimum capacity additions to satisfy local and zonal reliability standards are the result. Once capacity additions for each scenario have been established, then supplemental analyses will identify any potential roadblocks to permit that capacity and develop recommendations, if necessary, to help ensure that the needed capacity can obtain air permits. Electric reliability study results are expected in late October 2011 and late November 2011. Agency staff will hold a public workshop to inform stakeholders of the study results as they become available.
