Today in History: Niagara Falls hydropower

In 10 February 1961, the Niagara Falls hydroelectric project, the largest (at the time) hydroelectric facility in the Western world, was officially opened. The first generator, which had been producing current for some days before while undergoing tests, was officially placed in service to supply salable quantities of electricity. The size comparison was based on its designed 2,190 megawatt installed capacity when all 13 generators were brought online in 1963.
