University to install unique microgrid and community solar combination in Washington, D.C.

A new microgrid being built by Scale Microgrid Solutions and Urban Ingenuity will accomplish the unusual feat of serving its host — a Washington, D.C., university for deaf and hard of hearing students — and powering a community solar program.

The microgrid will be capable of providing Gallaudet University, which has about 1,400 students, with almost all of its electricity during a grid outage. In addition, it will serve the District of Columbia community solar program, available to Washington, D.C., residents, nonprofit organizations and small businesses.

Microgrids and community solar are rarely paired and their primary purposes are different. While microgrids are chiefly installed to provide reliable power during grid outages, community solar programs are designed to give those who cannot easily install solar on-site — renters, for example, or those that lack adequate roof space — an opportunity to participate in a renewable energy project. A community solar program allows them to subscribe to a solar array built off-site and receive a credit on their electricity bill for doing so.

Ryan Goodman, CEO of Scale Microgrid Solutions, described the Gallaudet University microgrid as a “breakthrough system that not only will deliver valuable resiliency benefits for the university but also provide the surrounding community with access to cleaner energy.”

Virtual front of the meter

Capable of serving 1,500 nearby households or small businesses, the community solar program came about through a collaboration with the district’s local utility, Potomac Electric Power (PEPCO), a subsidiary of Exelon. It will work by tracking the electricity produced from distributed solar panels connected to Gallaudet’s campus and then allocating the output as community solar credits. Scale Microgrid describes the approach as “virtual front of the meter,” meaning Scale can develop the project without the need for extensive cabling costs that would be required to aggregate many distributed solar systems and connect them directly to PEPCO’s grid. Instead, they simply connect to the nearest power panel and the utility tracks the output through sensors and software.

Expected to go online in fall 2023, the microgrid will also deliver several other benefits, according to Scale Microgrid. These include reliable, clean and lower cost energy for the university and congestion relief on the city’s electricity grid. 

Scale Microgrid Solutions will design, build and operate the project with a consortium that includes Urban Ingenuity, Schneider Electric, Tesla, Mitsubishi, CHA Consulting and New Columbia Solar.

The microgrid consists of:

  • 2.5 MW of solar panels spread across campus rooftops and parking garages.
  • A 1.2 MW/2.5 MWh Tesla Megapack energy storage
  • A 4.5 MW combined cooling, heat and power system.
  • Advanced microgrid controls.

“As a flagship educational institution for Washington, D.C., and as a cornerstone of the global deaf and hard of hearing community, Gallaudet deserves tremendous credit for providing the vision and leadership required to build climate solutions, while ensuring a more just and resilient local community. We are honored to be part of this world-class team,” said Bracken Hendricks, CEO of Urban Ingenuity, which finances and develops clean energy projects that promote social equity and housing affordability.
