Bornholm Island Acts as Microgrid Lab for Denmark’s Green Ambitions

microgrid

Denmark has an ambitious target to produce 100 percent of its electricity from renewable sources by 2050. But integrating renewable energy into the system makes it difficult to balance the intermittent supply with demand. With its high abundance of renewable energy, Bornholm Island, just south of Sweden, was the perfect test site for the … [Read more...]

The Microgrid Way: Going Green with Solar & Supercapacitor-based Energy Storage

Supercapacitor-based Energy Storage

If utilities offered their customers solar energy and took advantage of supercapacitor-based energy storage, we could significantly cut greenhouse-gas emissions. That’s the word from Omer Ghani, CEO and co-founder, Kilowatt Labs, which produces supercapacitor-based energy storage called Sirius Energy Storage and the Centauri Energy Server, … [Read more...]

Hawaii Campus Can Go 100% Renewable Thanks to Solar Microgrid

solar microgrid

University of Hawaii Maui College plans to go 100 percent green--likely a first-of-its-kind on a college campus--thanks to a solar microgrid equipped with 42 MWh of energy storage that serves five campuses. Johnson Controls is providing the battery storage and controls and Pacific Current -- a subsidiary of Hawaiian Electric Industries -- … [Read more...]

Rebuilding with Community Microgrids in Wake of California Fires: Sonoma County

resilient community microgrids

In the wake of the fires that ravaged Sonoma County in October 2017, the Clean Coalition — a non-profit that aims to accelerate the use of clean energy and technologies — is working to create community microgrids in the area. The organization compares efforts in Sonoma County to work in Puerto Rico, where hurricanes ravaged the island and … [Read more...]

Military Tests Electric Vehicle-to-Microgrid Use at Miramar Base in San Diego

vehicle-to-microgrid

US Marine Corps Air Station Miramar in San Diego is the site of a new electric vehicle-to-microgrid-utility grid test and demonstration project. Six 15-passenger electric vans will be equipped with bidirectional, vehicle-to-grid (V2G) charge/discharge capability and integrated into the air station's site-wide microgrid during the project's first … [Read more...]

Why These 10 Microgrids Won Funding in California

California microgrid projects

Ten California microgrid projects recently beat 150 others in a competition for $51.9 million in state grant money. What set them apart? The proposed* winners had to meet strict requirements, demonstrating a business case for advanced microgrids that support the state’s energy and greenhouse gas policies. That included proving that projects had … [Read more...]

Energy Storage Gets Biggest Boost in Years. Thank you FERC

energy storage

A recent federal ruling is likely to give energy storage its biggest boost in years, and buoy microgrids along the way, by granting storage more access to revenue from competitive wholesale electricity markets. Issued February 15 by the Federal Energy Regulatory Commission, the rule aims to eliminate barriers that prevent energy storage from … [Read more...]

“Stale” Time-of-Use Rates May Undercut Benefits of Energy Storage in California

energy storage California

California's grid operator is considering a load shift product that could beat "stale" time-of-use rates in its ability to avoid greenhouse gases and generate income for energy storage system owners and operators. The problem, for storage system owners, is time-of-use rates are getting “stale,” and don’t represent what mix of fuels are producing … [Read more...]

The Good, Bad and Ugly of Vehicle-to-Grid Services

vehicle-to-grid

All eyes are on Pacific Gas & Electric (PG&E) as it tests the ability of EVs to help power homes during outages and provide demand response. Will vehicle-to-grid live up to its big promise? Industry insiders are both optimistic and cautious. “The biggest challenge to using EVs to flow power back to the grid is that doing so would … [Read more...]

Will This Solar Community Microgrid Save Money AND Generate Income?

solar community microgrid

Researchers at University of California, Riverside, are testing a control system for a solar community microgrid that will decide how to dispatch assets — reaping energy savings and perhaps generating income. The Bourns College of Engineering research team is working on a power system for a microgrid located at the Chemehuevi Indian Tribe … [Read more...]
