TEPCO’s emissions have increased since it had to indefinitely shut down nuclear plant after a July 2007 earthquake, as it has been forced to increase output from oil-fired and other thermal power plants.
The company did not reveal the projected costs for building the plant.
Yamanashi prefecture will provide the land for the facility.
The move marks TEPCO’s second multi-megawatt solar project, as Japanese utilities aim to cut CO2 emissions per kilowatt-hour by 20% over the five business years that started in April 2008, compared with 1990 levels.
TEPCO announced in October 2008 that it and Kawasaki city, near Tokyo, would work to construct two solar plants which will have a combined capacity of about 20 MW.
