      Xcel Energy to Build 7 Community Microgrids with Siemens and Fluence

      Xcel Energy is seeking regulatory approval to move forward with seven microgrids, at a cost to the utility of $23.4 million, chosen from a community resilience solicitation that the Colorado utility issued in May. The microgrids will serve the Denver International Airport Automated Guideway Transit System; National Western Center; Denver Rescue Mission’s Lawrence Street Community Center; City of Arvada Center for the Arts and Humanities; Town of Nederland Community Center; Summit County Middle School; and Alamosa Family Recreation Center. The petition for approval and cost recovery is before the Colorado Public Utilities Commission (Proceeding 19A-0225E).

    2. Interior Gives VI Energy Office $625000 to Support Energy Resilience at Hurricane Shelters

      Interior Gives VI Energy Office $625000 to Support Energy Resilience at Hurricane Shelters

      The Virgin Islands Energy Office (VIEO) was chosen as a recipient of $625,000 in Fiscal Year 2019 funding under the Energizing Insular Communities (EIC) grant program, funded and administered through the U.S. Department of the Interior’s Office of Insular Affairs. The VIEO will utilize the grant to develop a Solar Plus Storage Micro-Grid pilot project that will be integrated at the St. Croix Educational Complex’s emergency hurricane shelter. The micro-grid will enable the emergency shelter to function reliably during extended grid outages and significantly reduce the use of fossil fuel generators that have proven difficult to maintain and costly to fuel.

      Top Federal Energy Official Visits Alabama Power's Smart Neighborhood

      Deputy Secretary of Energy Dan Brouillette toured a home at Reynolds Landing in Hoover, where Alabama Power partnered with Signature Homes, Southern Company, the U.S. Department of Energy’s Oak Ridge National Laboratory, and technology vendors to create the Smart Neighborhood. Reynolds Landing homes feature emerging energy-efficient technologies, materials and appliances. The neighborhood is connected to a nearby community-scale solar energy system with natural gas and battery backup, the first of its kind in the Southeast.

    4. Let's Kill 'Utility-' or 'Grid-Scale' Storage

      Let's Kill 'Utility-' or 'Grid-Scale' Storage

      Ask people how they segment the energy storage industry, and you'll often hear them divide it between customer-sited or behind-the-meter storage and "utility-"or "grid-scale storage." But if you then ask them what they mean by "utility-scale," you can't get a clear answer. Is it 5 MW, 10 MW, more than 20 MW? Do they mean "front-of-meter"? Or connected to the bulk transmission system? No, we're not calling for the end of the large-scale storage industry. We're saying that distributed, smaller-scale storage can provide all the same value to the grid that large-scale storage can and should be explicitly encouraged to compete on playing fields that policymakers have leveled everywhere.

    5. California’s Shutting Off Power to Prevent Fires. Here Are Some Better Options.

      California’s Shutting Off Power to Prevent Fires. Here Are Some Better Options.

      California’s major utility may shut off power across most of the San Francisco Bay Area this week to prevent fires as dry, windy weather closes in. But surely, the world’s fifth largest economy can figure out a better long-term strategy than periodically leaving hundreds of thousands of people in the dark. Some argue that particularly fire-prone regions on the wildland-urban interface could disconnect from the larger grid and rely on local renewables generation and storage entirely.

    6. Oregon Utility Partners with Cities to Achieve Resiliency with Microgrids

      Oregon Utility Partners with Cities to Achieve Resiliency with Microgrids

      Beaverton is the second Oregon city that will embrace microgrids for resiliency, working with utility Portland General Electric (PGE), which says it plans additional partnerships with cities. PGE’s microgrid projects are designed in part to provide resiliency if and when an earthquake hits the Oregon coast. The city of Beaverton will own their new emergency operations center, 300 kW of solar PV, and a 1,000 kW diesel standby generator. PGE will own the 250 kW storage system, which it will use, when available, for frequency control

      Microgrid to Serve as Core of Connecticut Mixed-Use Project

      The developer of a $110-$120 million mixed use project in Manchester, Connecticut plans to incorporate a microgrid that taps into opportunity zone federal tax breaks. The Manchester Broad Street Parkade microgrid will include around 1 MW of solar PV,  2-3 MW of natural gas-fired combined heat and power, batteries, and a water heating loop. The microgrid will be capable of operating continuously in tandem with the utility grid or autonomously, in island mode, in the event of grid outages.

      North Carolina Approves Duke's First Solar+Storage Residential Microgrid

      North Carolina regulators on Friday approved a solar+storage microgrid project proposed by Duke Energy, designed to help maintain reliable power for a small town called Hot Springs in the western part of the state. The project includes a 2 MW solar array and 4 MW lithium-ion battery, and will be Duke's first utility-scale solar+storage project for residential customers. The microgrid is a small part of Duke's broader plan to roll out more storage on its system.

      Microgrid Maintains Power Supply During Emergency Simulation

      The Bronzeville Community Microgrid can keep power flowing in an emergency, ComEd recently announced after conducting a test. The “simulated islanding” test checked the resiliency of the microgrid by mimicking events that have the potential to affect power delivery, including weather calamities,  cyber attacks and acts of terrorism. The tests ComEd conducted demonstrated the microgrid’s ability to provide power in island mode while drawing upon distributed energy resources (DER), including battery energy storage and solar photovoltaic PV, to serve customers.

      Microgrids at Ontario Technology Park to Offer Model for Energy Sharing

      Many tend to think of a microgrid as an enclosed campus with generation, energy storage and a resource management system, all islandable from the grid. But that thinking is limited. Microgrids also can involve small commercial communities, as planned by Canadian company Stantec, projects that right-size distributed energy resources so that an entire community benefits rather than just the host facility.

    13. California’s Wildfire Threat Could be an Opportunity for Clean-Energy Microgrids

      California’s Wildfire Threat Could be an Opportunity for Clean-Energy Microgrids

      California’s biggest investor-owned utilities are expected to de-energize power lines more frequently this year to stop them from igniting fires when the weather is dry and windy. It’s one of the fastest and cheapest ways for utilities to keep wildfires from sparking. But there’s an obvious downside: Whole communities can go dark for hours or even days. With those concerns in mind, some energy companies are urging state officials to incentivize microgrids and smaller standalone energy systems, such as rooftop solar paired with batteries, in fire-prone communities. Those technologies, the companies say, could help keep the lights on during preemptive power shutoffs.

      Miramar Microgrid to Demonstrate Reliable Power from Landfill Gases

      The microgrid at Marine Corps Air Station Miramar took another big step this week with an expansion that will demonstrate landfill gas as a reliable fuel for an islanded microgrid. This microgrid is considered one of the most sophisticated under development with five distributed energy resources, including solar, energy storage, landfill gas, diesel and natural gas plant, and EV charging. The first phase of the demonstration project paired solar and fossil fuels. Its second phase, announced this week, will demonstrate the interplay between landfill gas and energy storage.

      The US Department of Defense wants to reduce costs and speed time to install military microgrids, so is seeking demonstration projects via a newly issued request for proposals. Through its Installation Energy Test Bed, the Defense Department intends to fund multiple projects that speed microgrid design, simplify component and system integration, and accommodate expansion of military microgrids. Many already have invested extensively in generation assets, distribution systems, substations, load configurations, storage, metering and other energy infrastructure.
