Feb 25, 2026 - Inside 100-Year-Old Hydro Plants Still Producing Electricity Two hydroelectric power plants in Fergus Falls, Minnesota have been operating for over a century — and remarkably, much of their original equipment is still in place. In this detailed tour, we examine early 20th-century hydro turbines, generators, voltage regulation systems, and control equipment that continue to produce reliable electricity along the Otter Tail River. Featured in this video:• Historic hydroelectric generators still in service• Original exciter and rheostat voltage control systems How generators are controlled and monitored • Large legacy transformers replaced by modern units• The basement turbine level• An early compressed air ice-agitation system used behind the dam These facilities demonstrate how durable early electrical infrastructure can be — with machinery that has outlived many newer power stations. Up next: A visit to the Hoot Lake hydro plant, a World War I–era facility that outlasted the mid-century coal plant beside it.
