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 […]

Hydroelectric power generation hit a 10-year high in Europe in 2024, while hydro growth in other regions—most notably China—kept the technology at the top of the list when it comes to global energy output from renewable resources. The International Hydropower Association (IHA) in its 2025 World Hydropower Outlook said hydro is playing a “stablizing role” in Europe and elsewhere when it comes to power supplies at a time of heightened concern about volatile markets and shifting policies around energy, particularly in the U.S.

Renewable energy developer and project operator Agilitas Energy announced it the company has acquired two late-stage hydropower development projects from Advanced Hydro Solutions. Agilitas on June 24 said the 30-MW Tygart Hydropower Project in Grafton, West Virginia, and the 14-MW Jennings Randolph Hydropower Project in Garrett County, Maryland, represent Agilitas Energy’s first hydropower assets. It […]

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.

Power generators and transmission system engineers have to rethink their planning strategies, and must continue to develop tools to allow more solar, wind, and other forms of renewable energy to populate the power grid. Integrating renewable energy resources such as solar and wind into the electric power grid involves addressing challenges, starting with the intermittent […]

Global mining giant Rio Tinto said it will invest $1.2 billion to modernize a hydroelectric power plant in Quebec, Canada. The company on May 15 said the project is part of its bid to secure future aluminum production in the Canadian province. The money will pay for upgrades to the Isle-Maligne hydropower plant, which was commissioned in 1926 in Alma, Quebec.

Major German BESS Project Closes Financing. Energy transition bank NORD/LB announced it has closed an €87 million ($94 million) financing package with Nofar Energy for construction of a 104.5-MW/209-MWh

As wind and solar dominate global investment in renewable energy, hydropower’s potential to enhance grid resilience and expand energy supply remains largely untapped, and that potential is only expanding with the integration of advanced technologies like artificial intelligence (AI).

U.S. production of coal has continued to decline since peaking in 2008, according to a report from the U.S. Energy Information Administration. The EIA–on the same day earlier this month when President Trump signed an executive order designed to increase U.S. coal production and coal-fired power generation—released data showing the U.S. produced 578 million short tons (MMst) of coal in 2023, or less than half of the amount produced in 2008.
