  • Microgrids in this database include systems serving electricity to multiple buildings and/or consisting of more than one distributed energy resource. Microgrids must operate either continuously or conditionally during normal operating conditions.
  • Microgrids with a Generation or Storage Capacity of 0.0 kW could represent generation or storage systems with unknown capacities.
  • Microgrids that operate continuously supply power to the host site on a regular basis, both in grid-connected and island mode, and can be relied upon for uninterrupted power during extended grid outages.
  • Microgrids that operate conditionally do not supply power to the host site on a continuous basis while grid connected. Instead, power supply to the site is based on the availability of renewable resources or market signals such as demand response or real-time pricing.
  • All microgrids in this database must be capable of supplying continuous power to site loads when disconnected from the larger grid.

About the Microgrid Installation Database

The U.S. Department of Energy Microgrid Database is a comprehensive source of information on microgrid installations in the United States. Established in 2018, the Microgrid Database is maintained by ICF Inc. and is funded by the U.S. Department of Energy. The database is updated on a semiannual basis.
