Energy Storage

Microgrids have proven their role in enhancing the reliability, resilience, and sustainability of the modern power system. Kirk Edelman, CEO of SolMicroGrid, provided POWER with several lists detailing the technologies behind microgrids, the companies that can benefit from deployment, and the services the systems can provide for their end-users.

Today’s energy resilience toolkit includes a growing array of technologies, including diesel generators, natural gas systems, lithium-ion battery storage, solar-plus-battery microgrids—and now, a new class of hydrogen-based solutions that generate clean electricity from moisture in the air. No single option is universally ideal, but understanding their strengths and applications can help communities build more robust and flexible emergency energy strategies.

EDP Renewables North America (EDPR NA) has inaugurated the company’s 200-MW Scarlet II Solar Energy Park, in Fresno County, California. Scarlet II follows EDPR NA’s Scarlet I Solar Energy Park—a 200-MW solar farm with and 40 MW/160 MWh of battery energy storage system (BESS)—which achieved commercial operation in 2024.

Abundance Energy, sonnen, and Energywell Technology Licensing on May 6 said they will work together on development of behind-the-meter, battery-enabled VPPs. The program is designed to support retail energy customers of Texas-based Abundance Energy, while also providing support for the state’s power grid.

In late March, the Department of Energy (DOE) announced it would eliminate four efficiency standards enacted during the Biden administration. In addition, the Trump administration has issued statements suggesting that the power to choose appliances and energy-efficiency standards should not belong to the federal government, setting the stage for a state-level approach.

Battery Energy Storage Systems (BESS) are revolutionizing our power grids, dramatically enhancing resilience, and facilitating greater integration of renewable energy sources like solar and wind. This technological evolution promises a cleaner, more sustainable energy future, but it also introduces significant new risks, particularly fire safety challenges. High-profile incidents involving lithium-ion battery systems highlight critical gaps […]

Major German BESS Project Closes Financing. Energy transition bank NORD/LB announced it has closed an €87 million ($94 million) financing package with Nofar Energy for construction of a 104.5-MW/209-MWh

The energy industry, and particularly those participating in renewables, battery storage, and electric mobility, and their supply chain (solar panels, wind turbines, battery components, etc.), are facing

Participation in wholesale energy markets offers a critical source of revenue for battery energy storage systems (BESS). Across transmission organizations in the U.S., storage operators can deploy their units to participate in various wholesale markets.

The clean energy transition is progressing rapidly, but this extraordinary transformation is not without its challenges: outdated power grids and a lack of balancing technology means that we are wasting vast amounts of clean energy and resources through curtailment. To address this, we need an integrated approach combining grid upgrades alongside the greater deployment of balancing […]
