Muskrat Falls Hydroelectric Generating Facility

An 824 megawatt (MW) hydroelectric generating facility is being constructed at Muskrat Falls on the lower Churchill River, approximately 30 km west of Happy Valley-Goose Bay. The facility consists of two dams and a powerhouse, and will be the second-largest hydroelectric facility in the province when complete.

Harnessing the power of Muskrat Falls requires extensive and prudent planning. Consistent with industry best practice, Nalcor Energy used a front-end loading approach in the project’s planning and early design stages. Through early engineering and site preparation work, Nalcor’s project team increased the quality and accuracy of the development plans for Muskrat Falls, and mitigated many risks that could arise during construction.

Nalcor also worked with three of North America’s largest turbine generator engineering firms to design, model and test the four turbines for the generating facility. According to these companies, the turbine efficiency at Muskrat Falls will be the highest ever obtained in North America. Learn more about the engineering behind Muskrat Falls here.
