September 10th, 2018 by Carolyn Fortuna on Clean Technica The US Department of Defense’s (DoD) first wind-powered microgrid is nearly ready at Otis Air National Guard Base on Cape Cod, Massachusetts. Unveiled on August 29, 2018, by the 102nd Intelligence Wing and project partners, the “grid-connected microgrid” will serve as a model for similar Air National Guard and Department of Defense (DoD) projects. …
Investor-owned utilities in California forecast that by 2025, 85 percent will leave their systems for renewable energy through community choice aggregation
Microgrid Knowledge, Aug 2018 Quickly growing community choice aggregations (CCA) are expected to play a significant role in drawing 85 percent of customers away from California’s investor-owned utilities by 2025, according to a new report. Provided by Wang An Q/Shutterstock.com The community aggregation report was one of three on grid disruption released by Next 10, an organization with a goal of improving …
Minigrid costs can fall by more than half again by 2020, reaching $0.25 per kilowatt-hour
ESI-Africa, August 2018 Until recently, Gbamu Gbamu, a rural community in Nigeria’s Ogun State, was left without access to electricity – cash-strapped utilities could not justify the expense of extending the main grid to the community. Enter minigrids and the road to affordable and reliable electrification. With no prospect of grid extension in sight, the Gbamu Gbamu1 community eschewed the …
Hawaii microgrid legislation aims to remove several obstacles to microgrid development, including interconnection barriers.
DEEP DIVE By Robert Walton@TeamWetDog, June 27, 2018, Utility Dive Microgrids are a popular topic these days, particularly following a devastating 2017 Atlantic storm season. Hawaii would seem to be a natural fit to develop more of these systems as its island grids are relatively small and remote. Hawaii Gov. David Ige is considering signing legislation to help spur the development …
Hawaii legislature backs microgrids for enhancing community and grid resilience after lava mangles utility equipment
June 1, 2018 By Lisa Cohn Microgrid Knowledge Following the volcanic eruptions on Hawaii’s Big Island — where poles and equipment have been damaged or destroyed by lava — both Hawaii Electric Light (HELCO) and the state are moving toward boosting microgrid development. The eruptions from the Kilauea Volcano began May 3 on the Big Island and continue, with lava mangling utility-owned electrical …

Supercapacitor-based energy storage for microgrids avoids over-sizing. Micro-grid engineering becoming a macro profession.
Supercapacitor-based energy storage, on the other hand, is much simpler. This technology stores energy on the surface of the electrolyte, which means there is no chemical reaction. “Electrical energy comes in and is stored as electrical energy. It releases electrical energy back into electricity when discharged,” Ghani explained. Still supercapacitor-based energy storage hasn’t been used before because it has its …
Half of island without power, but Puerto Rico generation back up to 72%, as microgrid rules are released
GTM Jan 8 2018 Puerto Rico Energy Commission Lays Out Rules for a Future Microgrid Landscape With power restored for just about half of the island’s residents, and 1.5 million still without power, regulators look toward a remade grid. By EMMA FOEHRINGER MERCHANT Cleanup and electricity restoration efforts in Puerto Rico are ongoing. The Puerto Rico Energy Commission unveiled 29 pages of proposed …
Building and rebuilding efficiently and for resilience
Getting cities right can yield major dividends. For instance, research has shown that investing in compact, connected, and efficient cities could substantially reduce greenhouse gas emissions by 3.7 Gt CO2 per year by 2030 and generate savings of as much as US$17 trillion by 2050. But many national governments fail to recognize the importance of investing in sustainable urban infrastructure, continuing …
David Roberts on microgrids: This is the path to a cleaner, more reliable, more resilient energy grid
By David Roberts and Alvin Chang Dec 15, 2017, Vox If we want a livable climate for future generations, we need to slow, stop, and reverse the rise in global temperatures. To do that, we need to stop burning fossil fuels for energy. To do that, we need to generate lots of carbon-free electricity and get as many of our energy uses as possible (including …
