Hydroelectricity

In 1889, a hydroelectric power plant generated alternating current electricity which was for the first time made available to consumers at a significant distance from its origin. A 13 mile power line linked the Willamette Falls Electric Co. power plant to Portland, Ore. Two 300 h.p. Stilwell & Bierce waterwheels together drove a single phase, 720 kilowatt generator. It was not the first hydroelectric power plant, for one had been demonstrated in Appleton, Wisc., 30 Sep 1882 with a small dynamo. Rather, it is the use of alternating current that is significant, for this makes possible long-distance transmission that overcomes the problems of direct current. AC generators driven by steam power had been in use elsewhere since 1886.
