iconProduct and services

The ISO wholesale energy market is comprised of distinct day-ahead and real-time processes. The energy products and services traded in our market allow us to meet reliability needs and serve load. The market also offers services in which qualified entities can buy and sell congestion revenue rights and engage in convergence bidding activities.

Learn about our products and services

iconResource adequacy

The reliability requirements and resource adequacy programs provide deliverability criteria that each load serving entity must meet, and provide rules for counting resources that must be made available to the ISO. The ISO reliability requirements program is intended to complement the state's efforts to implement resource adequacy programs.

About the California ISO

The ISO manages the flow of electricity across high-voltage, long-distance power lines that make up 80 percent of California's and a small part of Nevada's grid. The nonprofit public benefit corporation also operates a competitive wholesale energy market, and conducts transmission planning to identify grid expansion needs.
