Energy Storage

Microgrids have grown in importance as the need for a reliable and resilient supply of power has grown. The technology has proven itself for a variety of commercial and industrial (C&I) enterprises, in both urban and rural areas where a source of off-grid—or in some cases grid-connected—energy is needed, whether a backup power or as a primary source of electricity.

A hydrogen production company that develops the fuel using renewable energy is moving forward with plans for a $1.85-billion solar-powered manufacturing facility in California.

A startup company led by former executives with major technology and energy groups is betting on the use of natural gas and battery energy storage to provide data centers with on-site power, freeing those sites from reliance on the traditional power grid.

Concentrated solar power (CSP) plants with thermal energy storage (TES) systems face significant material challenges. Specifically, industry-standard 347H austenitic stainless steel used in the manufacture of molten salt tanks can be subject to severe stress relaxation cracking (SRC). The results of a consortium project could have an answer for the problem. The findings suggest that […]

A battery energy storage system (BESS) described as the largest deployed to date in the European Union (EU) has been commissioned in Bulgaria. Officials with the country’s Ministry of Energy said the 124-MW/496.2-MWh BESS, also the largest in the Balkans, supports the stability of Bulgaria’s power grid along with its transition to the use of more renewable energy resources.

Fluence Energy, a global group that delivers intelligent energy storage systems, services, and asset optimization software, announced the start of production at a new manufacturing facility in Goodyear, Arizona. The facility that opened May 20 will produce enclosures made with U.S. steel and battery management system (BMS) hardware for Fluence’s grid-scale energy storage systems.

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.
