NTT Inc. and Mitsubishi Heavy Industries Ltd. (MHI) conducted an optical wireless power transmission experiment using a laser beam to wirelessly transmit energy over a distance of one kilometer. By irradiating a laser beam with an optical power of 1 kW, the team succeeded in receiving 152 W of electric power. This marks the world’s […]

The Tennessee Valley Authority (TVA) will collaborate with ENTRA1 Energy—NuScale’s exclusive global strategic partner—to develop a 6-GW nuclear portfolio, including six ENTRA1 Energy power plants on TVA sites, the companies announced on Sept. 2. Under the agreement, ENTRA1 Energy will develop and own nuclear assets across TVA’s seven-state service region, selling electricity to the nation’s […]

A solar power project in the Gobi Desert has moved the needle on the size and scope of global photovoltaic installations, aided by innovation in equipment and construction. The numbers tell much of the story

The U.S. power grid has delivered electricity reliably for decades. However, today the grid faces challenges that are driving transformation, reshaping its operational scope and the technologies on which it relies.

Inspecting and monitoring long-distance transmission lines has always been both costly and dangerous for utilities. Networks that stretch across remote, rugged terrain make traditional methods like climbing towers, deploying helicopters, or sending out ground crews resource-intensive and risky for workers. Today, autonomous drones are changing this process by offering a faster, safer, and more cost-effective […]

In the past decade, we have seen “once in a century storms” almost every year, flash floods wiping out entire towns, and extreme heat that melts shoes on pavement. Our climate is becoming more extreme, and we need to be proactive in preparing our infrastructure for more to come. The annual average for U.S. billion-dollar […]

Regulators in North Dakota have given their approval for a 1,490-MW natural gas-fired power plant, a combined-cycle station that Basin Electric Power Cooperative officials said would provide the area with its first new baseload electric output in more than four decades. South Dakota utility commissioners, meanwhile, are set to consider an application for a smaller, […]

Great River Energy’s dynamic line rating (DLR) project is the largest DLR deployment to date in the U.S. based on the number of sensors installed. Early results identified a 48.92% increase in power carrying

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 […]

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.
