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

Creating opportunities for distributed energy resources
Distributed energy resources will be a valuable part of the resource mix to ensure reliable management of the green electric grid. These resources are located on the distribution system and include energy storage, plug-in electric vehicles (PEV), demand response and combinations thereof that include photovoltaic solar. The ISO is helping remove barriers and creating opportunities for these resources to provide grid services.

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.
