California ISO - Documents By Group

Flexible capacity procurement
The ISO will need sufficient flexible capacity to reliably operate the grid as additional variable resources come on line to meet the state's 33% renewable target. This initiative explores short and long-term changes to the ISO backstop procurement authority so the ISO can procure the upward and downward ramping capacity required to accommodate sudden output changes inherent in variable resources, such as wind and solar.
