The First Jordan Hydro-Electric Power House, also known as the Rutenberg Power Station or the Naharayim Power Plant or the Tel Or Power Plant, was a conventional dammed hydroelectric power station on the Jordan river, which operated between 1932 and 1948. It was situated in the Emirate of Transjordan (modern Jordan), but built to supply power to Mandatory Palestine (modern Israel). The plant was built in an area known as Jisr el-Majami, later renamed by the Palestine Electric Corporation as Naharayim, and following the Israel–Jordan peace treaty it is today part of the Jordanian area of Baqoura.
