At the Edison Electric Institute (EEI) annual meeting this week in Las Vegas, the tone was one of collaboration with partners from Washington to distributed generation companies. Those partnerships will be needed as the investor-owned utility (IOU) industry fights not so much a war on coal as a war for mindshare and wallet share in […]

Temporary power may be the most widely distributed “distributed” generation worldwide, and its distribution is spreading, thanks to its ability to quickly meet urgent needs not only for event, construction, and post-disaster emergency power but also for fast-growing economies and stressed grids. That’s making it a serious competitor for “permanent” power in some situations. When […]

Anyone who follows either the energy industry or the military knows that all branches of the U.S. military have aggressive goals for renewable energy and for improving energy security and independence. Microgrids are a key part of that plan. When I wrote about military microgrids in “The Military Gets Smart Grid” back in January 2012, […]

Aside from places where microgrids have a track record—educational, industrial, and commercial campuses—commercial and community microgrids are still the domain of early adopters, but the number of people wanting to travel the trail they are blazing is increasing. A microgrid is any collection of interconnected loads and distributed energy resources within clearly defined electrical boundaries […]

If you’re looking for the easiest place to deploy microgrid technology, look at islands. That was the general consensus of presenters at the 4th Military & Commercial Microgrids Summit in Washington, D.C., held June 17-19. In addition to a presentation about a microgrid being developed for Necker Island—owned by Sir Richard Branson, founder of the […]

If, as Navigant Research suggests, the global microgrid market will exceed $40 billion annually by 2020, where is all the capacity going, and what’s fueling it (literally and figuratively)?
