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.

Policy perspectives

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.
