Community Microgrids = the Grid of the Future
Key features:
• A targeted and coordinated local grid area served by
one or more distribution substations
• High penetrations of local renewables and other
Distributed Energy Resources (DER) such as energy
storage and demand response
• Staged capability for ongoing renewables-driven
power backup for critical and prioritized loads across
the grid area
• A solution that can be readily extended throughout
a utility service territory – and replicated into any
utility service territory around the world
A Community Microgrid is a new approach for designing and operating the
electric grid, stacked with local renewables and staged for resilience.
