Community microgrids provide a new approach to the design and operation of the power grid at the community level. These microgrids, serving a specific area and supported by renewable energy and other distributed energy resources (DERs), help achieve a sustainable, secure, and cost-effective energy system. The installations, which can include energy storage among their DERs, can provide indefinite, always-on power. That’s of particular importance in areas prone to extreme weather events. A BlockEnergy installation in Florida, approved as a pilot project by the Florida Public Service Commission, is an example of a community microgrid that already has proved its worth. Tampa-based BlockEnergy, considered among the world’s first utility-owned, residential community microgrid developers, in 2022 partnered with home-builder Lennar and Tampa-based Metro Development Group to launch a 37-home microgrid community within the Medley at Southshore Bay residential development in Wimauma, Florida. Each home has power generation and battery energy storage that supplements electricity from the local grid. The system is scalable and, importantly, storm-resilient. That was proven last year when Hurricane Ian pummeled Florida, leaving more than 2.2 million power customers without electricity. The BlockEnergy homes at Medley at Southshore Bay, though, never lost power. None of the microgrid equipment was damaged by the hurricane.
