Australian Naval Microgrid Faces Operational Challenges

Giles Parkinson of Renew Economy describes operational problems faced by a microgrid installed by Carnegie Clean Energy at an Australian naval base. The Garden Island microgrid, located in a naval base off the port of Fremantle south of Perth, was supposed to be a shining light for the future of distributed energy, and potentially the world’s … [Read more...]

Ameresco and Duke to Build Unusual Floating Solar Microgrid at World’s Largest Military Base

Ameresco, Duke Energy and the military are combining forces to create a unique project at Fort Bragg in North Carolina — a floating solar microgrid.  Floating solar projects — solar panels installed on buoyant structures in a body of water — have been gradually emerging worldwide over the last decade. The technology is still relatively rare … [Read more...]

California Microgrids Flex Their Skills During Blackouts

California microgrids stepped up during the mid-August rolling blackouts, delivering flexible load and providing backup electricity, as extreme heat left the state short on power. Stone Edge Farm’s microgrid and three microgrids operated by Bloom Energy were among those that provided resiliency for their owners and community members on August … [Read more...]

Military Finds Integrating Storage into Microgrids Improves Performance, Lowers Costs

Integrating energy storage into microgrids can improve reliability and reduce costs on military bases that can take advantage of wholesale power markets and tax incentives, according to a report written for the US Department of Defense. The study — Design, Modeling, and Control of Hybrid Energy Storage System for Defense Installation Microgrids … [Read more...]

Three Key Ideas Emerging about Microgrids in an Era of Societal Disruption

Microgrids are among the disruptive class of tech, that which challenges the status quo to improve society. However, lately a technology’s worth is based less on how well it disrupts and more on how well it responds to societal disruption. With the disruption brought by COVID-19, products like teleconferencing, home delivery and telemedicine … [Read more...]
