Advanced energy technology group AMPERA announced the company has completed production of what it called the first full-scale, 3D-printed nuclear reactor module.

The Nuclear Regulatory Commission (NRC) has proposed what may be its most consequential reactor-licensing overhaul in a generation, a 553-page rulemaking that seeks to rewrite core pieces of the regulatory framework governing how commercial nuclear plants are sited, licensed, built, modified, operated, renewed, fueled, and ultimately decommissioned. Issued July 1, the proposed rule, “Modernizing Reactor […]

Deployable Energy’s Unity demonstration reactor has achieved criticality at Idaho National Laboratory (INL), making it the third Department of Energy (DOE)–authorized advanced reactor to reach the milestone ahead of the July 4 deadline set under President Trump’s May 2025 nuclear executive order. The U.S. DOE on July 1 said Deployable Energy’s Unity reactor completed a […]

Arevon’s Eland solar-plus-storage project in California provides power for the Los Angeles region and is helping the state progress toward its goal of providing more renewable energy.

At a recent energy conference, power sector stakeholders agreed the looming fleet of hyperscale data centers will require vast amounts of clean, firm capacity. But while nuclear looks like the most plausible

Data center developers have mastered server density and cooling, but power interconnection remains stubbornly slow. Modular substations built in factories rather than fields are emerging as the most practical

Utilities and power generation companies are bolstering operational efficiency and plant reliability by implementing advanced analytics and artificial intelligence (AI)–driven predictive maintenance

Shadow a utility work crew for a day and you would be amazed at how many obstacles, inefficiencies, and headaches they face from the mobile applications they use. These teams are productive despite those applications, not because of them.

For decades, the most radioactive category of low-level waste in the U.S. has had a disposal plan that exists only on paper: a deep geologic repository that was never built. Late last week, the Nuclear Regulatory Commission (NRC) moved to replace that plan with one that can actually be licensed. The agency proposed a sweeping […]

Electricity demand is climbing at a pace the power industry hasn’t seen in a generation, and the companies trying to feed it with geothermal energy are mostly racing in one direction: drill faster. Ormat Technologies is making a different bet. The company that has built and run geothermal plants for six decades thinks the constraint […]

The unique demands of floating offshore wind turbines require a blend of specialized coating systems engineered to help prevent corrosion and extend asset service life in some of the world’s harshest environments.

An independent developer of utility-scale nuclear power projects said it has an agreement with GE Vernova Hitachi Nuclear Energy for a nuclear power plant utilizing small modular reactors (SMRs). Elementl Power on June 18 said the facility, sited along the Ohio River about 100 miles southeast of Columbus, has a planned capacity of as much as 1.5 GW.

Soltec has announced that it is now able to provide PFE-compliant certification for its U.S. SFOne and SF7 series 1P and 2P trackers, reinforcing the company’s ability to support utility-scale solar projects in the U.S. under the new regulatory and market conditions.

Valar Atomics has achieved self-sustaining criticality and completed zero-power testing at Ward 250, its Gen IV tri-structural isotropic (TRISO)-fueled modular high-temperature gas reactor (HTGR), at the Utah San Rafael Energy Lab in Emery County. The project is the second advanced reactor to go critical under the Department of Energy’s (DOE’s) Reactor Pilot Program and the first DOE-authorized […]

Meeting the increasingly important but complex needs of the energy industry requires not only excellent design and engineering, but also advanced sensor capabilities that extend beyond the limits of current technology. A piece of the solution for enhanced technology will come from quantum sensors, which leverage quantum mechanics to deliver tools that will push past […]

Energy giant GE Vernova said the company continues to advance electrification and decarbonization goals as it adds more generation capacity to global power grids. The company on June 17 released its 2025 Sustainability Report, highlighting its emphasis on bringing new innovation and breakthrough technologies to the power generation space.

Utilities have long been accused of slow-walking innovation. Fair or not, the advent of artificial intelligence (AI) tools, and the subsequent wariness from those responsible for maintaining our most critical infrastructure, has only intensified that perception. But make no mistake: we’re in the midst of the most-rapid technological evolution of utilities in the power grid’s […]

Hydrogen has long been positioned as a cornerstone of the energy transition. But after an intense hype cycle, the conversation is shifting toward a more practical phase defined by targeted deployment and measurable value. Rather than serving as a universal solution to decarbonization, hydrogen is increasingly being recognized for what it does best: complementing electrification […]

A $350 million Department of Energy (DOE) coal-revival program has put $18.5 million toward the TerraSpark Energy Campus, a 1.6-GW greenfield project in West Virginia pairing Babcock & Wilcox (B&W) supercritical boilers with Mantel Capture’s molten borate carbon capture. In responses to POWER, developer TerraSpark laid out a 2030 startup target, a 95% to 98% […]

The electricity conversation in America has become increasingly focused on one question: How do we meet rising demand? The surge in artificial intelligence, data centers, electrification, and domestic manufacturing is placing unprecedented pressure on the grid. The industry’s response has largely centered on adding supply, such as building more generation, expanding transmission, and accelerating new […]

MiCo Co. Ltd. announced that its subsidiary, Hyundai Heavy Industries Power Systems Co. Ltd. (HPS), has signed a share purchase agreement (SPA) to acquire a 100% stake in Netherlands-based NEM Energy B.V. from Mutares SE & Co. KGaA, a German-listed investment firm. The transaction, which includes NEM Energy’s German subsidiary NEM Balcke-Dürr GmbH, is scheduled […]

A Colorado-based fusion energy company said the U.S. Dept. of Energy (DOE) has approved the company’s preconceptual technical design for its commercial fusion power plant.

As fire-weather risk expands beyond California, utilities are turning to sub-kilometer, asset-level forecasts to support public safety power shutoff decisions they can defend in front of regulators. When the National Weather Service (NWS) issued routine convective outlooks on the morning of May 27, 2025, public guidance for the Houston metro called for widespread 30 to […]

NextNav, a Positioning, Navigation, and Timing (PNT) company with a history of telecommunications mergers, requested a rule change that would allow it to build out a network of high-power broadband operations. The proposed rule would impact every U.S. electric utility.

The power generation sector, including electric utilities and grid operators, recognizes the value of moving equipment underground to mitigate outages, lessen risks to assets, and reduce the chances of that equipment causing a wildfire.

Companies are deploying a variety of strategies in efforts to strengthen the power grid against severe weather and other issues.

From EOP-012-3 to Order 587-AB, from Cold Weather Critical Component inventories to dual-fuel conversions, the bulk power system has spent five years rewiring how it prepares for extreme cold. Winter Storm Fern, the latest test, showed the system ran “very close to the edge.” The last five winters have given the North American power sector […]

Antares Nuclear Inc.’s Mark-0—a sodium heat-pipe-cooled microreactor fueled by high-assay low-enriched uranium (HALEU) tri-structural isotropic (TRISO) fuel compacts—has achieved zero-power criticality at Idaho National Laboratory’s (INL’s) Reactor and Critical Experiment (RACE) facility, becoming the first advanced reactor to reach that milestone under the Department of Energy’s (DOE’s) Reactor Pilot Program. The development, announced on June […]
