Existing law provides for the establishment of an Independent System Operator (ISO) as a nonprofit public benefit corporation and requires the ISO to ensure efficient use and reliable operation of the electrical transmission grid consistent with achieving planning and operating reserve criteria no less stringent than those established by the Western Electricity Coordinating Council and the North American Electric Reliability Council. Existing law, the Clean Energy and Pollution Reduction Act of 2015, provides for the transformation of the ISO into a regional organization, with the approval of the Legislature, pursuant to a specified process. That process provides that modifications to the ISO's governance structure, through changes to its bylaws or other corporate governance documents, will not become effective until the ISO, the Public Utilities Commission, the State Energy Resources Conservation and Development Commission, the State Air Resources Board (state board) , the Governor, and the Legislature take specified actions on or before January 1, 2019.
This bill would delete the above-described provisions providing for the transformation of the ISO into a regional organization. The bill would authorize the ISO and the electrical corporations that are participating transmission owners whose transmission systems are operated by the ISO, in lieu of the ISO managing related energy markets, as provided, to use voluntary energy markets governed by an independent regional organization, provided that specified requirements are satisfied. The bill would authorize the ISO, on or after January 1, 2027, to implement tariff modifications accepted by the Federal Energy Regulatory Commission to operate the energy markets whose rules are governed by an independent regional organization if the governing board of the ISO adopts a resolution, as specified, finding that each of the specified conditions have been, or will be, adopted by the independent regional organization. The bill would require the ISO to maintain the necessary technical capability to operate energy markets, as specified, and would require the ISO to continue its functions and responsibilities as a balancing authority, as provided.
Existing law requires the Power Exchange to provide an efficient competitive auction, open on a nondiscriminatory basis to all suppliers, that meets the loads of all exchange customers at efficient prices, and authorizes the Power Exchange governing board to form appropriate technical advisory committees composed of market and nonmarket participants to advise the governing board on relevant issues.
This bill would delete these provisions.
