Kansai Electric in U.S. Merchant Power Venture

LCG, Aug. 29, 2000--Kansai Electric Power Co., Japans second-largest electric utility, said this morning that will enter the U.S. merchant power market in a joint venture with the American investment bank Morgan Stanley Dean Witter.

The joint venture will cost between $50 million and $100 million to establish and will be owned equally by the two firms. It will be named Naniwa Energy.

The Osaka-based Kansai said it will send to the U.S. six gas turbines currently being used as peaking units in western Japan. Kansai said it would sell the units, which have a total capacity of 360 megawatts, to Naniwa for an undisclosed amount.

Naniwa expects to begin producing power in the U.S. by next June and will also trade electricity on the U.S. market through a new unit, Kansai said.

Japans electric industry is in the early stages of restructuring. In the latest move, independent power producers were allowed in March to begin selling power to industrial and commercial customers on bilateral contracts.

A Kansai official said operating the generating units in the U.S. and trading on the American power market will give his company first-hand experience in a deregulated electric industry.
