翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ellsworth Power House and Dam ： ウィキペディア英語版 Ellsworth Power House and Dam The Ellsworth Power House and Dam, the latter also known as the Union River Dam, is a hydroelectric power generation facility on the Union River in Ellsworth, Maine. The dam, located just north of downtown Ellsworth, impounds the river to create Leonard Lake, named for project's engineer, James Leonard. The powerhouse is a Renaissance Revival building located at the western end of the dam. The power plant, built in 1907, was one of the first peaking power plants built in the state, and the hollow concrete dam is one of the highest Ambursen-type buttress dams ever built. The facility was listed on the National Register of Historic Places in 1985.〔 ==Description and history== The Ellsworth Dam is located between two bluffs which flank Maine's Union River, and rise to a height of more than . The dam consists of a series of buttresses, spaced about apart, which provide support for two large slabs of steel-reinforced concrete that span the river between the bluffs. The dam is in height, with a spillway long. The buttresses, set on a granite bedrock ledge, are three feet thick.〔(【引用サイトリンク】title=NRHP nomination for Ellsworth Power House and Dam )〕 The power station is located at the base of the dam on the west bank of the river. It is a 1-1/2 story structure built out of concrete blocks, with a red tile gabled roof. The Renaissance Revival structure has round-arch windows which are connected by a stone belt course, and there are Palladian windows in the gable ends. An addition on the building's rear was built with similar styling.〔 The power station was built in 1907 by the Bar Harbor and Union River Power Company, to designs by its engineer, James Leonard. The company was merged in 1925 into the Bangor Hydro-Electric Company, now part of Emera. The plant was acquired by Black Bear Hydro in 2009, and sold to Brookfield Partners in 2013. The dam is in the process of being relicensed; its most recent permit expires in 2017. In its current configuration, the plant produces about 30,000 megawatt hours of electricity annually. 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「Ellsworth Power House and Dam」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.
