A microgrid generally operates while connected to the grid, but when the electric grid fails or is resource constrained due to a natural or man-made disaster, the microgrid is able to operate on its own to provide power for the facility(ies) connected to it. Microgrids also have the added flexibility of being able to operate with either centralized generation, like combined heat and power systems, or distributed energy resources, such as solar and energy storage. Microgrids can provide reliable, resilient, affordable, and efficient electric power to critical infrastructure and electricity consumers. However, microgrid cost-benefit considerations and competing policy and regulatory goals present both opportunities and barriers to maximizing their value.
Many State Energy Offices are interested in supporting microgrids across their states and NASEO supports State Energy Offices’ efforts through publications, convenings, and the Microgrids State Working Group.
