The plant operated between 1932 and 1948. The opening ceremony took place on 9 June 1932, attended by Emir
Abdullah I of Jordan and British officials including the High Commissioner
Arthur Grenfell Wauchope, Colonel Charles Henry Fortnom Cox, and Sir Steuart Spencer Davis. The plant ceased operations following the
1948 Arab-Israeli war. It was captured and looted by the Iraqi Army on 14 May 1948. Transjordan had a secret agreement with Israel regarding protection of the works. United States
Chargé d'affaires Wells Stabler reported in a confidential despatch that when the Iraqi army arrived, the Israeli operators of the plant blew up some of the electricity generators (
alternators) in the plant and the plant was subsequently looted by the Iraqi troops. they were released only after the
Armistice Agreements were signed on 3 April 1949. Stabler's despatch on 11 July 1949, written after a visit to the site, read: It is understood that prior to the hostilities In May 1948, the Jordan Government and the Jewish Agency reached some form of agreement concerning the protection of the Hydro-Electric works. It is possible that the Jordan Government would have been able to observe this agreement if it had not been for the arrival of the Iraqi forces. When the Iraqi forces came into the area, the Israelis departed, but only after blowing up certain of the dynamos in the main dynamo building. Later the Iraqi finished the job, even removing numerous machines.... The area has been under the control of the Arab Legion since the departure of the Iraqi troops three months ago. All looting and damage has been stopped by the Legion and the area is under guard. ... It is quite obvious that the Rutenberg Hydro-Electric works can only be operated again by an agreement between Jordan and Israel. Jordan, on its part, is incapable of operating such a works by itself and, moreover, the Israelis can control the flow of the Jordan. Israel, on the other hand, cannot commence operations of the works as all the buildings are in Jordan territory. In addition, Jordan can control the flow of the Yarmuk River. It would appear that it would take some time yet to reach an agreement on the operation of the Rutenberg Hydro-Electric works as it remains, along with the Dead Sea Potash Works, an important bargaining point for Jordan. ==1948 proposals to reopen==
