Concerning electric power system transmission planning.
Summary
Requires electric utility Integrated Resource Plans (IRPs) to include a 20-year, rather than 10-year, forecast of the availability and requirements for regional generation and transmission capacity, and adds to IRP transmission assessment requirements.
Requires electric utilities to consider conditional firm transmission services when planning and selecting renewable resources.
Requires electric utilities to consult with federal, interstate, and industry entities to plan and develop transmission capacity, and encourages utilities to engage in statewide, multiutility, and interstate transmission planning processes.
Directs the Energy Facility Site Evaluation Council (EFSEC) to oversee the siting of transmission facilities that are at least 500,000 volts alternating current or at least 300,000 volts direct current, and are located in more than one county and one electric utility service territory.
Directs the EFSEC to prepare nonproject Environmental Impact Statements (EISs) for transmission facilities with 230 kilovolts or more, and specifies how lead agencies may use these nonproject EISs for a specific project.
