摘要:
The paper describes the hydro-electric development at Owen Falls and the economics of the scheme. The development is under the control of the Uganda Electricity Board, formed in 1948.Owen Falls is on the White Nile about 2 miles downstream from the sole outlet from Lake Victoria, the third largest lake in the world, 26 000 square miles in area. A mass-concrete gravity dam, 100ft high and 2 500ft long, has been built with a power station alongside for an ultimate plant installation of ten Kaplan turbines, each coupled to a 15 000-kW alternator. One unit commenced generating in January, 1954, and five more units are being installed progressively.In addition to power generation, the scheme is designed to provide long-term storage in Lake Victoria for the benefit of Egypt.The average rainfall on the catchment area of 103 000 square miles is 43 in, but only 7% of the run-off flows down the White Nile. Despite this, the volume of water available at Owen Falls is considerable, ranging from the minimum of 10 500 cusec to the maximum of 43 000 cusec.The capital cost of the scheme, excluding transmission, is about £12 million. The revenue of the Uganda Electricity Board has risen from £70 000 a year in 1948 when the maximum demand was 1½ MW to an anticipated £700 000 a year in 1954. It is estimated that demand will reach 90 MW in 1962. Maximum output is 700 million kWh per annum with 60% load-factor.

摘要:
In 1947 it was decided to build a hydro-electric power station nearthe source of the White Nile, to make available an abundant supply of electricity for the encouragement of industry and the development of the mineral resources of Uganda.The paper describes the station, which is now in operation, the problems that have been encountered in the construction and operation of the system, and the development which is taking place.
