System planners and grid operators are treating extreme heat as an assumed operating condition given new pressures, including drought, demand growth, and fuel concerns. Will it be enough? For decades, the U.S. power system treated extreme heat as a tail risk, managed through seasonal readiness—something for which to prepare. But hotter conditions are now arriving […]

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 […]

Utilities, federal agencies, and the national labs have finally assembled the tools to harden the grid against an increasingly hostile environment. The question is whether they can put them together fast enough. When a line of storms tore across the Northeast in late April 2025, racing from Ohio into central Pennsylvania, meteorologists recognized the signature […]

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.

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 […]

According to the State of the Global Climate 2024 report released by the World Meteorological Organization (WMO), the continued rise in global temperatures is driving a measurable increase in both the frequency and intensity of extreme weather events. Among these, tropical cyclones, including hurricanes and typhoons, as well as extreme precipitation events, have emerged as […]

Global clean energy group ContourGlobal announced the start of commercial operation of another utility-scale solar-plus-storage project in Chile, one the company said features Latin America’s longest-duration battery energy storage system.

New Jersey-based Thea Energy, one of several U.S. companies working to commercialize fusion energy, said the company has raised $100 million in Series B funding. Thea is advancing stellarator technology to provide baseload fusion power. The company, which has several investors, is moving toward beginning construction of its Helios power plant (Figure 1) by the […]

It’s a known fact that wind power sites across the U.S. eventually will reach the end of their lifecycles. So now what? The industry is coming upon an age where owners and operators must repower these sites by leveraging existing infrastructure to help meet the growing national demand for power. With more than 75,000 turbines […]

Fives ProSim, a subsidiary of the Fives Group and an expert in industrial process simulation and optimization, announces the release of ProSimPlus Python API. This new solution enables users to run the engine of ProSimPlus, a leading software dedicated to the design, simulation, and optimization of continuous industrial processes, directly from the Python environment. A […]

With hundreds of 7FA and 7EA gas turbines approaching end-of-life thresholds and industry-wide constraints on forgings and shop capacity, MD&A has invested a decade in reverse engineering, supply chain development, and production of rotor components to offer utilities an independent path forward. The gas turbine bubble of 2000 to 2004 saw between 600 and 700 […]

Expected annual energy yield (PVout) is a fundamental number for every utility-scale photovoltaic (PV) project. It informs the design, shapes the budget, feeds the financial model, and influences what investors and lenders are willing to accept. Behind every expected yield estimate, however, is a range of uncertainty. Part of it comes from the solar resource […]

Florida-headquartered Star Catcher Industries said it has raised $65 million in an oversubscribed Series A funding round, as the company continues its effort toward building the first space-based power grid. Star Catcher, based in Jacksonville, said the new investment—led by B Capital and co-led by Shield Capital and Cerberus Ventures, the venture arm of Cerberus […]

There has never been a time when so much power was needed so fast. Driven by the artificial intelligence (AI) revolution, more data center capacity is in development or under construction now than has been built in all of history. According to analyst firm Industrial Info Resources (IIR), each month of 2025 saw at least […]

After decades of stagnation, nuclear power is firmly back in the energy discussion. Surging electricity demand, hyperscale data centers hunting for firm round-the-clock power, and growing pressure to decarbonize industrial heat have converged to revive interest in both new reactor construction and lifetime extensions of the existing fleet. The resurgence is broader than a single […]

Industry analysts say faster construction timelines, along with lower energy costs, are fueling consistent growth in a solar power sector increasingly constrained by regulators.

A Houston-based nuclear technology startup is advancing a high-temperature gas-cooled reactor (HTGR) design that targets outlet temperatures of 950C (1,742F)—well beyond the range of most advanced reactor

As the first generation of wind turbines ages out of manufacturer service agreements, operators are discovering that the smarter path forward isn’t wholesale replacement—it’s re-engineering components to

Utilities now operate in a far more dynamic environment shaped by distributed energy resources, an increasing number of distributed generation sites, and the emergence of large, high-demand loads and a growing number of connected devices across the grid.

Across the power sector, plant owners are confronting a fundamental question: how long can existing assets continue to operate safely and economically? What was once a long-range planning exercise has become an immediate strategic priority, driven by a convergence of market, operational, and policy pressures. Load demand is rising at a pace many utilities and […]

Global energy demand is outpacing supply, driving the need for expanded and more reliable infrastructure across oil and gas, nuclear, and renewable energy systems. Steel is essential to building and connecting this infrastructure, delivering the strength, durability, and performance required to operate in extreme environments and at scale. American-made steel provides consistent quality, material traceability, […]

The U.S. electrical grid is aging and under increasing strain from rising energy demand driven by technologies like data centers and electrification, making modernization urgent. Much of the current infrastructure is outdated, with many transmission lines nearing the end of their lifespan and relying on less durable materials like wood. Modernizing this infrastructure requires stronger, […]

The U.S. Nuclear Regulatory Commission (NRC) has proposed a sweeping new licensing framework designed to push microreactors out of the lab and onto the grid at unprecedented speed. The proposed rule, called Part 57, is paired with a broader agency overhaul that earlier this year created the Office of Advanced Reactors (OAR), headed by longtime […]

Many utilities have been slow to embrace distributed energy resources (DERs) and, in some cases, have reshaped rate structures and compensation mechanisms to limit their growth. This is not simply resistance to change. It is a rational response to incentive structures that favor building infrastructure over technology advancement and energy optimization and efficiency.

Japan’s largest power generation company has made a proposal to invest $2 billion for construction of a 500-MW combined-cycle and simple-cycle natural gas-fired power plant on the Hawaiian island of Oahu.
