The D.C. Circuit Court of Appeals has ruled against the Trump administration’s order to keep the J.H. Campbell coal-fired power plant in Michigan operating. The decision that could impact other orders that have been issued to keep U.S. coal-fired power plants operating past their scheduled retirement dates.

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. […]

Horizon Technology Finance Corp., an affiliate of Monroe Capital, on September 10 said that the RoHo Capital Opportunity Fund LLC, a joint venture formed by Horizon and CR Financial Holdings, Inc., the holding company for Roth Capital Partners, LLC, has provided a $20-million senior credit facility to NeoVolta, Inc., with the ability to increase the facility to $30 million upon mutual agreement. An initial $20 million was funded at closing to support NeoVolta’s continued growth.

An independent energy development company and a long-time manufacturer of wood products have signed an agreement to develop geothermal projects in Washington and Oregon.

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 […]

North Carolina State University, the New York Power Authority (NYPA), and EPRI have demonstrated a megawatt-class solid-state transformer (SST) on a live 13.2-kV utility distribution feeder, marking what the partners describe as the first independent validation of a megawatt-class SST under real-world distribution conditions. The NC State-built prototype was connected at EPRI’s power delivery laboratory […]

The U.S. Dept. of Energy (DOE) said the agency has closed a loan of as much as $1.9 billion to NextEra Energy to support the restart of the Duane Arnold Energy Center in Iowa.

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 […]

America’s emerging electricity challenge is increasingly an infrastructure challenge. For much of the energy transition, attention concentrated on the cost of producing electricity. Solar developers focused on module prices, battery developers compared cell costs and round-trip efficiency (RTE), and utilities evaluated competing resources using measures such as levelized cost of electricity (LCOE). Those calculations remain […]
