The U.S. Department of Energy (DOE) has invoked emergency authority to compel Puerto Rico’s public utility to dispatch mothballed oil-fired and fossil-fueled power units, citing an imminent threat to grid reliability following two major blackouts in less than a month. Energy Secretary Chris Wright, acting on behalf of the DOE’s Office of Cybersecurity, Energy Security, […]

Global mining giant Rio Tinto said it will invest $1.2 billion to modernize a hydroelectric power plant in Quebec, Canada. The company on May 15 said the project is part of its bid to secure future aluminum production in the Canadian province. The money will pay for upgrades to the Isle-Maligne hydropower plant, which was commissioned in 1926 in Alma, Quebec.

New transmission lines will help meet power needs this summer. Con Edison will energize newly constructed transmission lines in Brooklyn and Staten Island this month, helping to keep service reliable when the demand for power rises and challenges the electric delivery system. The underground cables, which represent a combined investment of $505 million, will provide […]

Project manager Bechtel said construction of the 1.3-GW Mammoth Solar facility in Indiana is moving forward, with the company on May 16 saying the project “kicked its construction activities into a higher gear this month.”

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.

All regions across the North American bulk power system (BPS) are generally positioned to meet peak demand under normal summer conditions, though elevated risks of electricity supply shortfalls could persist under extreme heat, surging demand, and resource variability, the North American Electric Reliability Corp. (NERC) warns. In its May 14–released 2025 Summer Reliability Assessment (SRA), […]

Advanced nuclear developer Oklo announced it has successfully completed borehole drilling for site characterization work at its Idaho National Laboratory (INL) site, marking a pivotal milestone as the company progresses toward constructing its first commercial Aurora Powerhouse—a liquid sodium–cooled fast reactor designed for scalable deployment. The standard nuclear project development step, involved “drilling of several […]

Why microgrids with hydrogen for backup power will create significant benefits for consumers and utilities. The energy grid in the U.S., particularly in regions like California, Texas, and the Northeast, is overstretched and increasingly unable to meet modern demands. California’s grid, for instance, is facing unprecedented strain with the sale of more electric vehicles (EVs), […]

Most of the 440 operable nuclear power plants (NPPs) currently deployed worldwide have long been recognized as potential targets for attack by enemy military forces or terrorists. Such an attack could not only destroy the power-generating capacity of the plant but also release a large plume of radioactive material having the potential to cause long-term […]

The deciding factor in the artificial intelligence (AI) race may come down to our ability to provide new data centers what they need most: massive amounts of constantly available electricity. In the U.S., data centers and their need to accommodate AI account for about half the projected growth of electricity demand through 2030. But the […]
