At a remote substation in the Midwest, I watched recently as a team of cybersecurity specialists gathered not to fix a breach but to simulate one. The substation—a medium-impact test site built by one of the nation’s largest utilities—has become a proving ground for the future of grid security. Before the North American Electric Reliability […]

Energy solutions provider Ameresco announced a partnership with Alaska’s Juneau Hydropower to develop, build, and operate a 19.8-MW hydropower station at Sweetheart Lake. The facility is located 33 miles south of downtown Juneau. The project also includes installation of a battery energy storage system (BESS) and more than 40 miles of high-voltage transmission infrastructure.

As the backbone of modern energy systems, smart grids and digital substations promise efficiency and sustainability—but they also open the door to escalating cyberthreats. This article dives into a layered cybersecurity strategy that blends integrated vulnerability assessments, robust protocols, and defense-in-depth tactics. Packed with practical insights and a look at breakthrough technologies, it empowers utilities […]

RENEW Energy Partners, a provider specializing in financing and deploying large-scale energy projects, has advanced the energy portfolio of Mass General Brigham (MGB), a nonprofit integrated healthcare system and biomedical research organization, with a major upgrade at Spaulding Rehabilitation Hospital.

The U.S. power sector seems to be increasingly pulled in two directions. While trundling toward rapid electrification, it is seeking to hold its ground on recent decarbonization triumphs. And while utilities and power companies are racing to add generation capacity, their prospects are limited by aging infrastructure and upended by supply chain constraints that have […]

A new paper titled “Facilitating Global Deployment of Floating Nuclear Power Plants” has been published by World Nuclear Association’s Cooperation in Reactor Design Evaluation and Licensing (CORDEL) Working Group. This paper highlights the benefits of the technology and focuses on progress made in the regulatory space, which is required for their international deployment. The pledged […]

County commissioners in North Dakota have signed off on a rezoning request from a local energy provider, a move that means a large coal-fired power plant could be used to supply electricity to a new industrial park.

Recurrent Energy, a subsidiary of Canadian Solar, and a global developer, owner, and operator of solar and energy storage assets, on July 7 announced that the 1,200-MWh Papago Storage facility in Maricopa County, Arizona, has reached commercial operation. The project is now dispatching stored energy to Arizona Public Service (APS), the state’s largest electric utility, […]

Utilities operate in high-stakes environments where operational resilience, infrastructure reliability, and workforce efficiency are essential for maintaining uninterrupted service. Cutting-edge field service management technology enhances field operations, improves safety, and streamlines emergency response with scalable automation, seamless geographic information system (GIS) integration, and predictive field service intelligence, ensuring efficiency and reliability in even the most […]

GE Vernova said the first of three blocks of a major natural gas-fired power plant in Taiwan is now online. The company on July 7 said the first 1.3-GW unit of the Hsinta power station is operating, part of the facility’s transition from burning coal to using natural gas.

A utility that serves customers in Missouri announced it plans to build an 800-MW natural gas-fired power plant, along with the company’s first large-scale battery energy storage facility, at a site near St. Louis.

Nuclear microreactors developed separately by Westinghouse and Radiant are poised to become the first fueled designs tested at the Demonstration of Microreactor Experiments (DOME) facility—the world’s first dedicated microreactor test bed slated to open at Idaho National Laboratory (INL) in early 2026. The first fueled experiment is expected to begin as early as spring 2026. […]

There is no room for missteps, miscommunication, or misunderstandings when it comes to nuclear maintenance. It demands precision, speed, and accountability. The tools and systems used during outages must function flawlessly, because when they don’t, the cost is more than money—it’s exposure, downtime, and slipping maintenance schedules. Some nuclear plants use a segmented model for […]

A global energy infrastructure management group said one of its solar-plus-storage projects in the UK is now online. Quinbrook Infrastructure Partners on July 1 said the 373-MW Cleve Hill Solar Park has started commercial operation, and represents the largest solar power and energy storage installation built to date in the UK. Quinbrook on Tuesday said […]

In drought-prone Southern California, Burbank Water and Power has implemented a groundbreaking stormwater capture and reuse system that saves more than eight million gallons of water annually. This

Built on degraded tidal flats in China’s Jiangsu Province, CHN Energy’s Rudong project combines 400 MW of offshore photovoltaic generation, grid-scale battery storage, and green hydrogen production with

Chile is rapidly moving to build more power generation capacity, with much of that effort focused on renewable energy resources and battery energy storage systems (BESS). The country as part of that ambition

In an era where energy costs continue to rise and climate concerns intensify, the inefficiencies of traditional power generation have become increasingly difficult to ignore. Conventional power plants often

The U.S. electric power sector is experiencing a surge in renewable energy deployment, yet the grid faces mounting pressure from skyrocketing demand and shifting federal policies. As data centers and

Taiwan is among several countries experiencing an energy crisis, with its supply of power struggling to keep up with demand from a rapidly growing high-tech sector. The country has long depended on imported

Large distances are something you get used to if you live in Australia. Perth, on the west coast, is about 2,500 miles away from Brisbane on the east coast. Even within the state of Western Australia (WA), the

An air gap is the distance between the rotor and stator of a large-scale hydroelectric generator. This gap is a very small distance in relation to the size of the rotor. Its measurement to tight tolerances is critical to prevent damage to and maintain efficiency of the generator. Static measurement of the air gap (Figure […]

NASA strives to understand the universe, whether that be the stars above us or Earth around us. One way NASA focuses on the Earth is through satellite, ground, and airborne Earth observations and modeling. NASA’s Earth Science projects work to further understand the Earth and its systems to better help humanity now and in the […]

Artificial intelligence (AI) is playing a huge role in heat rate optimization. In some cases, AI-driven models have analyzed operational data to recommend control settings that reduce heat rates by 1.5% to
