Electric Power Development Co., the utility known as J-Power, said Friday it began work on a 20 megawatt wind power station in western Japan.

The wind farm in Uwajima, Ehime Prefecture, will use nine turbines made by Mitsubishi Heavy Industries Ltd., the firm said in a statement. It didn't provide details on the cost.

J-Power has 18 operating wind farms across the country and expects the new plant to start in September 2014, it said.
