When completed in 1968, Muddy Run was the largest pumped-storage facility in the world. The facility is operated by the Susquehanna Electric Company, a subsidiary of Exelon Generation. Ernest Spey was the superintendent of Conowingo Hydroelectric Dam and the new Muddy Run facility until 1989. The facility's upper reservoir is the Muddy Run Reservoir, with a full pool elevation of over , and a usable storage capacity of . Muddy Run Reservoir was created by damming Muddy Run with a long, high, rock-filled dam.〔 The lower reservoir is the Conowingo Reservoir, created in the Susquehanna River by the Conowingo Dam, with a normal pool elevation of . The power house uses excess grid capacity during off peak hours to pump water from the Conowingo Reservoir into the upper reservoir through four diameter, vertical shafts. During peak power demand periods, the water is allowed to flow back from the lake through the shafts to the eight turbines causing the pumps to act as generators. Muddy Run has a capacity of 1,071 megawatts. The Muddy Run electrical machinery was designed by the noted engineer Eugene C. Whitney of Westinghouse Electric Company, who designed the machinery for the Grand Coulee Dam #3 powerhouse. Whitney "was present when the machines were first to be started. The operator was reluctant to take the first step. Gene said, 'Call your boss.' The boss said, 'If Gene says to start the machines, start them.' So they did, and water rose from the lower Susquehanna River to the upper reservoir, 400 feet above". The upper reservoir extends into Martic Township. The area around the upper reservoir is operated as a park, complementing the nearby Susquehannock State Park. Susquehannock State Park has an overlook trail with a good view of the Muddy Run facility. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Muddy Run Pumped Storage Facility」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
