Small modular reactors (SMRs) borrow steam turbine engineering from both coal-fired and nuclear plants, but the resulting “wet steam” problem, with exhaust moisture topping 15%, demands a fresh set of

A shorted rotor winding doesn’t care what year it is. Neither does a cracked retaining ring or a degraded stator insulation system. The physical mechanisms that take generators offline—fatigue

On Aug. 30, workers at the Palisades Nuclear Plant in Covert Township, Michigan, began loading 204 fuel assemblies into a reactor vessel that had sat empty since the plant shut down in 2022—the first time in U.S. history that a commercial reactor that had entered decommissioning began reloading fuel. Holtec International Chairman and CEO Dr. […]

Data centers are connecting to the transmission system faster than the reliability rules were built to handle and behaving nothing like the passive load those rules assumed. Here’s what the North American Electric Reliability Corp.’s (NERC’s) Large Loads Action Plan, a new class of registered entity, and a hard 2026 deadline mean for anyone planning, […]

The Department of Energy (DOE) on Sept. 17 announced the Quantum Genesis Q Competition, a $215 million initiative to fund private-sector teams racing to build the world’s first fault-tolerant, scientifically relevant quantum computer.

This article presents a practical four-phase engineering methodology for migrating legacy transmission substations toward adaptive protection architectures in power systems with high distributed energy resource (DER) penetration. Increasing DER integration introduces significant challenges to conventional protection schemes, including bidirectional power flow, dynamic fault current behavior, relay coordination complexity, and reduced protection reliability in aging substations. […]

Artificial intelligence (AI) data centers are being built at an unprecedented pace. There are more than 12,000 active projects in the U.S. currently seeking grid interconnection representing 1,570 GW of generator capacity and 1,030 GW of energy storage. Analyst firm Omdia predicts that AI will drive more than 50% of installed power generation capacity over […]

As reciprocating engines/gensets assume a larger role in distributed generation, data center infrastructure, and other critical duty applications, crankcase ventilation and the resulting emissions warrant increased attention and mitigation. When power generation professionals discuss engine emissions, the conversation typically focuses on the exhaust stack. While this emphasis is justified, it underestimates another emissions pathway: the […]

From two-year bushing lead times and hyperscaler demand to U.S. manufacturing expansion and the emerging 765-kV build-out, Trench Group CEO Bahadir Basdere explains where high-voltage equipment supply is under the most pressure. High-voltage grid components are becoming a critical constraint as utilities, transmission developers, original equipment manufacturers (OEMs), and hyperscalers compete for equipment needed to […]
