The California Independent System Operator Corporation (CAISO) provides electricity transmission and related reliability services under both State and federal authority that are essential to the California economy as well as the health and welfare of its citizens. In this regard, the CAISO’s core mission can be divided into three interrelated cornerstones: • Maintain reliable electric service; • Improve the efficiency of electric system operations, including the provision of open and non-discriminatory access to the transmission facilities under its control; and • Identify and promote new investments in transmission infrastructure in a coordinated, open, transparent and participatory manner.
