Shaping a clean, flexible grid
As the impartial grid operator for the bulk of the state’s power grid, the ISO opens access to the wholesale power market that is designed to diversify resources and lower prices. We are committed to preparing the wholesale market for implementing California’s environmental policies.
Understanding the ISO
The ISO operates a robust and reliable wholesale power system that balances the need for higher transmission reliability with the need for lower costs, and acts as a key platform to achieve California’s clean energy goals.
