Ameresco and Duke to Build Unusual Floating Solar Microgrid at World’s Largest Military Base

Ameresco, Duke Energy and the military are combining forces to create a unique project at Fort Bragg in North Carolina — a floating solar microgrid.  Floating solar projects — solar panels installed on buoyant structures in a body of water — have been gradually emerging worldwide over the last decade. The technology is still relatively rare … [Read more...]

California Opens ‘Diesel Alternative” Discussion in Microgrid Proceeding

California regulators are seeking comment from industry stakeholders on alternatives to diesel generators as part of an ongoing microgrid proceeding (19-09-009). The California Public Utilities Commission seeks comment by September 18. The state’s largest utility, Pacific Gas & Electric (PG&E), had originally planned to develop … [Read more...]

Puerto Rico Approves Utility Plan with Microgrid Mandate

After two years of debate and planning, Puerto Rico finally appears positioned to re-create its electric grid with microgrids and renewable energy, mandated in a new utility integrated resource plan (IRP). The mandate came from the Puerto Rico Energy Bureau, the island’s chief energy regulator, in late August. Utility IRPs are guiding … [Read more...]

Cook Islands Boosts Microgrid Capabilities with Storage

Rarotonga, the remote South Pacific island that is part of the Cook Islands, plans to boost its microgrid capabilities with new energy storage capacity. Under the terms of a deal signed with New Zealand’s Vector Powersmart, Rolls-Royce company MTU will supply three containerized battery storage units. The MTU EnergyPacks, packaged in … [Read more...]

Siemens Creates Living Lab in Princeton, NJ to Demonstrate Microgrids

Siemens, one of the largest companies in the microgrid arena, has created a living lab at its US technology headquarters in Princeton, N.J. to demonstrate how similar facilities can use microgrids. The microgrid includes solar photovoltaics, battery storage, electrical power infrastructure, building management systems and microgrid control … [Read more...]

Rolls-Royce to Expand Battery Production Capacity to Meet Demand for Microgrids

A Rolls-Royce business unit is increasing its capacity for producing containerized battery packs in response to growing demand for microgrids. The plan to expand capacity will see three former Siemens factory halls rebuilt which will allow the fitting of battery modules to several 40-ft containers simultaneously, as well as subsequent … [Read more...]

Community Microgrid Gets Boost from Energy Storage in California’s Goleta Load Pocket

As part of an ambitious project that aims to deploy a community microgrid that will help avoid outages due to fires, earthquakes, mudslides and other disasters in the Goleta Load Pocket, 40 MWh of utility-scale storage will go online in December. Groundbreaking on the project, called the Vallecito Energy Storage Resilience (VESR) project, has … [Read more...]

How Government Support Can Work Against Microgrids

Distributed energy resources make up the bulk of any microgrid. So incentives for DERs will mean more microgrids, right? Not necessarily, says Peter Asmus, research director at Guidehouse, who explains his new research on DERs in microgrids. As a bonus, Asmus also offers insight into Covid-19's impact on the microgrid market in this interview with … [Read more...]

How Solar, Storage & Microgrids Save Money at K-12 Schools: Free Livestream Discussion August 27

Microgrid Knowledge will host a livestream discussion August 27 with schools that are installing solar, energy storage and microgrids as a way to save money — and in some cases even earn revenue from their systems. The discussion, “Solar Microgrids for K-12 Schools: Saving Money and Educating for the Future,” will run from 2-3:15 pm and … [Read more...]

Microgrid Used as a Testbed for Neural Network

A research team at the US Department of Energy’s Argonne National Laboratory has tested a neural network for controlling power systems on a microgrid. The team set out to solve the challenge of modeling static and dynamic characteristics of a power system. A static characteristic is an action that does not change within a certain amount of … [Read more...]
