Emergency drawdown of Flaming Gorge is imminent, officials say. The water situation is crashing so rapidly that authorities can't confidently track the extent of it.

Orillia Power Generation has completed the purchase of a 9.6-megawatt hydroelectric generating station in Smooth Rock Falls, Ontario. The acquisition is considered a significant advancement for Orillia, according to Mayor Don McIsaac. The hydroelectric station operates as a “run-of-river” facility, connecting to the 115Kv transmission grid through a main output transformer. Electricity generated by the

TNB’s sediment brick experiment in Cameron Highlands is a small-scale pilot with an outsized idea at its centre: that the waste products of renewable energy infrastructure can build the communities that host it. At the bottom of Ringlet Lake in Cameron Highlands, beneath the cool highland water that feeds one of Malaysia’s oldest hydroelectric systems, lies a problem that most people have never thought about and few engineers enjoy discussing. Sediment. Enormous, accumulating, operationally inconvenient volumes of it. The rivers that flow into Ringlet Lake, including Sungai Jasik, deposit an estimated 200,000 to 400,000 cubic metres of sediment into the […]

Hydro-Quebec's Electricity Exports Halted Amid US Tariffs A significant disruption has occurred in the energy supply chain between Quebec and New England, as Hydro-Quebec stopped exporting electricity into the wholesale market of ISO New England. According to data from grid overseer ISO New England, no electricity has flowed on the main transmission line between the two regions since last Thursday, with a few exceptions. Executive Serge Abergel attributes this halt in exports to weather issues rather than politics or international trade tensions. As chief operating officer for Hydro-Quebec's US operations, Abergel explains that the company is adopting a price-driven strategy, taking advantage of lower prices brought about by warmer weather. This decision not only affects Hydro-Quebec but also has implications for New England's energy market. The halt in exports comes at a sensitive time, as the Trump administration has imposed tariffs on Canadian imports, sparking a trade war with Canada. The uncertainty surrounding these tariffs is particularly pertinent to hydroelectricity exports. ISO New England officials have sought clarification from US Customs and Border Protection and the US Treasury but have yet to receive definitive answers. Based on legal precedents, ISO New England officials do not believe the tariffs apply to electricity. The impact of this trade fight on electric bills remains uncertain. Hydro-Quebec has filed a cost-allocation proposal with federal energy regulators, should the situation change. For now, New England still enjoys a surplus of electricity, but the halt in exports highlights the complexities of international trade and energy markets.
