OSAKA, March 22 (Kyodo) — The Kansai Electric Power Co. group and oil distributor TonenGeneral Sekiyu K.K. announced Friday plans to build a mega solar power plant in Arida, western Japan.

The plant in Wakayama Prefecture will have the largest solar power output capacity within the Kansai Electric group at about 30,000 kilowatts, enough to meet the annual electricity consumption of 9,000 households.

Construction will begin in fiscal 2013, with power generation possibly to start in fiscal 2014, the companies said.

A 45-hectare plot of idle land owned by TonenGeneral will be used for the plant to be built and operated by Kansai Electric's wholly owned subsidiary, Kanden Energy Solution Co.

No estimate of the total project cost was revealed.

Elsewhere in Japan, the Kansai Electric group has a 10,000 kilowatt solar power plant in a waterfront area facing Osaka Bay.
