U.S. power infrastructure—the intricate physical fabric that laces together generation, transmission, and distribution—is under intensifying strain. Outdated and overextended, it must now absorb relentless growth from electrification and data centers or risk escalating reliability threats, surging costs, and a weakened global competitive edge. POWER examines the dysfunction and what it will actually take to future-proof […]

Energy Vault Holdings, a company that provides sustainable, grid-scale energy storage solutions, on June 11 announced the successful completion and start of commercial operation of the 57-MW, two-hour Cross Trails battery energy storage system (BESS) in Scurry County, Texas. The project, which marks the first fully executed asset under Energy Vault’s “Own & Operate” growth strategy, was completed ahead of schedule and will be supported by a 10-year offtake agreement with Gridmatic, a leading AI-enabled power marketer.

Microgrids have grown in importance as the need for a reliable and resilient supply of power has grown. The technology has proven itself for a variety of commercial and industrial (C&I) enterprises, in both urban and rural areas where a source of off-grid—or in some cases grid-connected—energy is needed, whether a backup power or as a primary source of electricity.

Energy equipment group GE Vernova said it has commissioned the first of four 250-MW variable speed units at THDC India Limited’s Tehri Pumped Storage Hydropower Plant, part of the Tehri Hydropower Complex. The 1-GW expansion will increase the facility’s power generation capacity to 2.4 GW, making it the country’s largest hydropower plant.

As threats to power companies rise—from cyberattacks to theft and vandalism—many utilities are rethinking how to secure facilities and critical infrastructure. Outdated systems that constantly trigger false alarms from wind, weather, or wildlife are draining resources—making it imperative for utilities to modernize their security to improve response, cut costs and reduce reliance on armed personnel.

The Southwest Power Pool (SPP) regional transmission organization (RTO) is joining with energy technology company Hitachi on development of what the groups say is an artificial intelligence (AI)-based solution to support power transmission reliability and flexibility challenges.

National Grid in the UK has begun construction of a new Uxbridge Moor substation complex in Buckinghamshire, a project designed to connect more than one dozen new data centers to the electricity provider’s network.

A startup company led by former executives with major technology and energy groups is betting on the use of natural gas and battery energy storage to provide data centers with on-site power, freeing those sites from reliance on the traditional power grid.

While many utilities are hardening power grid infrastructure by upgrading poles and wires—a necessary step—brute force solutions alone won’t be enough. To truly future-proof the grid, resilience must be rooted in intelligence via systems that anticipate, adapt, and respond dynamically.

Concentrated solar power (CSP) plants with thermal energy storage (TES) systems face significant material challenges. Specifically, industry-standard 347H austenitic stainless steel used in the manufacture of molten salt tanks can be subject to severe stress relaxation cracking (SRC). The results of a consortium project could have an answer for the problem. The findings suggest that […]
