Micro Power Plant Start-Up Aims to Spur Decentralized Energy Revolution in Myanmar

micro power

A solar energy-centered microgrid start-up -- one that develops what it calls micro power systems -- is bringing electrification for the first time to towns and villages in Myanmar. Gaining the support of foreign development organizations such as Norway's Norfund, Yoma Micro Power has installed 51 off-grid micro power plants in rural Myanmar … [Read more...]

Reverse Auctions May Become the Key to Energy Storage Rollout, EDF says

reverse auctions

When Xcel Energy conducted a reverse auction in 2018 to help build out its energy storage systems, it received hundreds of bids. It’s all about integrating energy storage into its wind and solar energy networks to increase reliability.  In a traditional auction, the seller does business with the highest bidder. But in a reverse auction, the … [Read more...]

Maine Lawmakers Revive Microgrid Bill as New Governor Creates a Pro-Green Climate

microgrids

Microgrids that regulators determine “serve the public interest” are back in play in Maine this year as lawmakers try to pass a bill that fell short a year ago. Legislators passed a bipartisan bill last year more clearly defining how microgrids could be created, but former Republican Gov. Paul LePage vetoed it. Newly elected Gov. Janet Mills … [Read more...]

PJM Rule Changes Could Reduce Revenue for Energy Storage

energy storage pilot

The PJM Interconnection has made a temporary change in the rules for its frequency regulation market that could mean lower revenue and market participation for energy storage. The proposed rule -- which still requires approval by federal regulators -- addresses price spikes, or "price excursions," observed by PJM staff. Reinstates floor … [Read more...]

How Two Arizona Microgrids Helped the Macro Grid: A Year in Review

Arizona microgrids

One year and 43 “events” later Arizona Public Service (APS) says it's happy with its foray into microgrids and is ready to build more. But not for the usual reason. The utility turned to its two microgrids 43 times not for backup power, but to help restore frequency within the Western Electricity Coordinating Council (WECC), which manages grid … [Read more...]

Community Microgrids: Central Pillar of the Local Energy Revolution

community microgrids

Community microgrids are popping up in cities and towns all over the U.S. as the local energy revolution takes hold. Recent storms and power outages are helping drive this trend, as well. A guide from Microgrid Knowledge, explores the role of the community microgrid and its growing popularity as many city leaders look for more clean, … [Read more...]

Microgrids and Energy Storage Helped Arizona Utility Prevail on Hot & Dark Days

microgrids and energy storage

It’s been a tough year for North American electric grids -- hurricanes, heat, fires, an eclipse. But an Arizona utility is reporting that it did just fine with some help from new microgrids and energy storage. “Driving past a microgrid or energy storage unit, many customers wouldn’t look twice, but those technologies are playing an increasingly … [Read more...]

Brain Research Tools Could Help Revolutionize Energy Storage Technology

energy storage technology

Duke University brain science researchers are hoping to use electronics they developed for non-invasive brain stimulation to revolutionize energy storage technology, making batteries safer, more efficient and less expensive. The idea to apply brain science technologies to battery technology came from Stefan Goetz, an assistant professor of … [Read more...]

Haiti Microgrid Operator Takes Preventive Steps as Hurricane Irma Nears

Haiti microgrid

Haiti microgrid operator Sigora Haiti reported Wednesday that it was preparing its facilities to minimize any damage from Hurricane Irma. The micro-utility company provides electricity to more than 8,000 people in northwest Haiti. Irma is expected to skirt the northern coast of Haiti, about 65 miles from the three microgrids: Môle-St-Nicolas, … [Read more...]

DOE Releases Much-Awaited Grid Study to Mixed Reviews

grid study

The U.S. Department of Energy released its much-awaited electric reliability grid study last night, and it was immediately met with mixed reviews from clean energy advocacy groups. Rick Perry, energy secretary, commissioned the study, citing concern that grid instability could occur as coal-fired generation declines and renewable … [Read more...]
