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.
Creating cross-regional benefits with the Energy Imbalance Market (EIM)
ISO advanced market systems automatically balance supply and demand for electricity every fifteen minutes, dispatching the least-cost resources every 5-minutes. In November, 2014 this voluntary energy imbalance market service became 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.

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.

Energy storage and aggregated distributed energy resource education forum - April 16 and 23
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.
