Emera and Sandia test DC power conversion to achieve grid of grids

Sandia National Laboratories and Emera Technologies are taking the next step to enable bidirectional flow between multiple interconnected microgrids — a grid of grids — under a project funded by the Department of Energy's (DOE) Technology Commercialization Fund. The effort stems from their partnership on a DC/AC hybrid microgrid demonstration … [Read more...]

Microgrid Talk: What’s next in microgrid innovation?

We've come a long way with being able to control all of the different energy sources in a microgrid, according to Chris Ellis, executive vice president of distributed infrastructure for PowerSecure. But, he says, we still need to see more microgrid innovation. "The technology's changing fast, and new energy sources are going to be available," … [Read more...]

Energy sharing in microgrids is a win-win — but complicated

Energy sharing in microgrids can benefit all parties involved — including utilities — but establishing successful sharing projects can be difficult because of regulatory, policy and technical hurdles. What’s more, it’s not easy deciding how to allocate payment for the energy among the energy users. Some of the few energy-sharing efforts … [Read more...]

A hydrogen microgrid for a home? A California utility achieves first step

Southern California Gas (SoCalGas) was the first large natural gas utility in the US to set a goal to achieve net-zero greenhouse gas emissions by 2045. And it's continuing to break barriers, this time by producing its first kilogram of renewable hydrogen meant for use in a residential hydrogen microgrid. According to Neil Navin, vice president … [Read more...]

Microgrid Talk: EV proliferation will drive microgrid growth

Xendee's chief technology officer, Michael Stadler, and lead engineer Zack Pecenak, explore the benefits of rapid, repeatable modeling and design as demonstrated at three military installations. The US Department of Defense (DOD), through its Environmental Security Technology Certification Program (ESTCP), has identified microgrids as a … [Read more...]

Look to the rooftop for the real show at this Manhattan convention center

New York's Javits Center attracts some big-name shows, among them NYC Comic Con. However, an even more impressive — but lesser known — act is happening on its rooftop. There you'll find what the convention center describes as the largest rooftop solar array in Manhattan, which is part of a 13-MW microgrid. New York Gov. Kathy Hochul drew … [Read more...]

Australia nickel mine plans to host world’s largest renewable microgrid

Giles Parkinson, founder and editor of Renew Economy, describes plans by Oz Minerals to build the world's largest renewable microgrid in Australia. The massive $1.7 billion West Musgrave nickel and copper project — given the green light by Australian mining company Oz Minerals late last week — will be a groundbreaking project for the sheer scale … [Read more...]

Not all microgrid controllers are created equal

Tim McDuffie, senior business development engineer at Smarter Grid Solutions, explains why different microgrid implementations require different controllers. When people think about microgrids, they often envision a microgrid in a box scenario where one or two energy sources such as a battery and solar panels are connected to a basic … [Read more...]
