What are we doing to green the grid?
The ISO is committed to supporting important energy and environmental policies while maintaining reliability through a resilient power grid system.
Integrating renewables reliably
The power mix
The ISO is focused on the reliable integration of zero-emission resources such as solar and wind power in support of the state's renewables portfolio standard. Read more

Unlocking mutual cross-regional benefits
As the only real-time energy market in the Western U.S., advanced ISO market systems automatically balance supply and demand for electricity every five minutes, dispatching the least-cost resources. This voluntary market service will soon be available to other grids operating in the West as a way to share reserves and integrate renewable resources across a larger geographic region--reliably and efficiently.

The century-old electric grid is evolving into a modern and sophisticated machine to unlock a greener economy and fight off global warming. Coordinating the alignment of environmental and energy goals is critical to developing a cleaner, reliable and more weather-resilient power grid. The ISO is collaborating with state and federal agencies, policymakers, stakeholders and end-user groups during this historic transformation to meet the challenges and opportunities ahead.
