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 […]

Nuclear energy is entering a new era. Across the United States and around the world, countries are looking to nuclear power to provide reliable electricity, strengthen energy security, and support economic growth. Advanced reactors and other innovative technologies are creating opportunities that would have been difficult to imagine when many of our current regulations were […]

NextEra Energy says an artificial intelligence (AI)–driven dispatch and outage-scheduling tool has saved its customers more than $20 million so far this year. Santee Cooper expects a custom AI weather-forecasting model to help it avoid spot-market purchases that can cost $100,000 an hour during extreme weather. Both utilities say the tools moved from concept to […]

The U.S. power grid is entering a period unlike any it has experienced in decades. Rapid electrification, domestic manufacturing, and the exponential growth of artificial intelligence are reshaping electricity demand. A recent report from Lawrence Berkeley National Laboratory, supported by the U.S. Department of Energy, projects that data centers alone could account for between 9.5% […]

Utilities and independent power producers have spent years adding sensors to their generating fleets and creating dashboards to view what they relay. But visibility into how a plant is operating isn’t the same as knowing what to do about it—and that gap is where Siemens Energy’s Omnivise Energy Management System is increasingly shedding light, explained […]

Following a competitive evaluation, Swedish nuclear technology company Studsvik AB has selected GE Vernova Hitachi Nuclear Energy and Samsung C&T as strategic collaborators for a proposed four-unit BWRX-300 project totaling about 1,200 MWe. The project is planned for either Studsvik’s licensed nuclear site in Nyköping or Målma in Valdemarsvik, and the first unit is expected […]

Florida-headquartered ONE Nuclear Energy said the company has executed a binding letter of intent (LOI) that would provide site control for development of Project Cayman, a 2.88-GW gas-fired power plant and 700-MW/2.88 GWh battery energy storage system (BESS) sited alongside a data center complex.

Texas data center developer TIDAL PWR, which says it has seven projects totaling 9.87 GW in its artificial intelligence (AI) campus development pipeline and designs its campuses to combine utility service and behind-the-meter generation, is collaborating with quantum technology company BTQ Technologies to determine how power and data center infrastructure could eventually accommodate quantum computing […]

A widening gas turbine supply crunch has prompted Ansaldo Energia to explore a new path back into the U.S. generation market after more than 30 years. The Italian manufacturer will supply California-based
