(',' ,... 7 '-.L:" 22 METROPOLITAN WATER DISTRICT it up to 33,000 volts for local distribution, Local power is now taken from the 33,000-volt Indian Service transformer bank. Sta- tion service is taken at 6900 volts from units No, 2 and No.3 through a 750-kva bank, supplying station power at 460 volts, and a 200-kva bank supplying station lighting, 'The 69,000-volt connection to the Gene pumping plant is used to parallel Parker power plaut with Boulder power plant through the District's 230,OOO-volt system, in order to effect interchange of power between Boulder and Parker power plants, and to supply power required by Basic Magnesium, Incorporated, and other cus- tomers of the United States connected to the District's system, This connection which is owned by the District will later be used for supplying Parker power to the District's pumping system. . Provision is made in the 161,OOO-volt switch rack for additional I lines to Phoenix and to the Gila pumping project, and for a con- ~ nection to the proposed Davis Dam power plant above Needles. The legal title to the entire Parker power plant as well as the dam is in the name of the United States, but the District is entitled to the exclusive use and benefit of units No, 3 and No.4. Under the supplemental contract of July 19, 1942, the United States retaius the use of these units for a period of ten years or more, duriug which time the District is to receive credits toward the amortization of its portiou of the cost of the plant at the rate of $475,00 per day for each unit. Generating uuits No, 1 and No.3 were operated in parallel with the District'~ system for the first time November 22 and were placed in regular operation December 13, 1942, Unit No, 2 was placed in regular operation .January 1. 1943, and unit No, 4 on May 26, 1943, The Parker plant was operated in parallel with the District's system when needed to supply power demands in excess of the capability of the units available to the District at Boulder, arid at such other times as power was available at Parker in excess of the demands of the Parker system, When the first two units were placed in operation on December 13, 1942, the sale of District unused Boulder energy to the Salt River Valley Water Users' Association and the Central Arizona Light and Power Company was discontinued, Progress was made in dredging the river channel below Parker Dam to increase the head and power output of the Parker power plant. The maximum output of the plant, now approximately 100,000 kw, will be increased slightly by further dredging of the rh-er bed below the plant.
