Microgrids

Montgomery County is installing microgrids to allow key facilities to operate without any power from the utility grid, ensuring public safety and community resiliency during major storms and other disasters.

About Microgrids

Microgrids are on-site clean power generation systems that allow critical operations to run independently of the power grid. Microgrids combine technologies such as solar panels, combined heat and power generation systems, batteries, and advanced controllers that include built in cyber-security. Microgrids are resilient because they allow facilities to generate their own power and run uninterrupted during storms and other major power outages. Montgomery County plans to install microgrids at Public Safety Headquarters and Montgomery County Correctional Facility. Montgomery County also is working with utilities to develop additional microgrids for the community. Learn more about Montgomery County’s microgrid projects by watching this presentation from October 2017 given as part of a panel on Improving Resilience Through Microgrids and Battery Storage at the Edison Electric Institute in Washington, DC.

Environmental and Financial Benefits

Montgomery County has entered into an innovative public-private partnership that allows the microgrids to be installed without any upfront costs to the County. The on-site power generation at these two sites are anticipated to reduce greenhouse gas emissions as much as taking 765 cars off the road or planting 94,000 trees. They also will ensure that the County can continue to provide critical services to the community during major storms and other external events.

Projects

Public Safety Headquarters

Public Safety Headquarters, Gaithersburg.

The microgrid project is expected to generate 11.4 million kilowatt hours of clean and low emissions energy. Ground breaking began in July 2017. Project completion is expected by the end of 2018. More…

Montgomery County Correctional Facility

Montgomery County Correctional Facility, Boyds.

Project Completion is expected by the end of 2018. More information will be posted as it becomes available.

Partner Projects

This proposed community microgrid by our partner Pepco Holdings would allow Montgomery County residents to meet their essential needs during a power outage by providing off the grid, clean energy to power emergency services, gas stations, grocery stores, pharmacies, etc. More…
