Sumitomo Electric Industries, Ltd. (SEI) has completed the construction of the largest wind farm in Japan, “Wind Farm Tsugaru,” which was ordered by Kajima Corporation.
A press release said that the project required a 34-km-long power cable described as “unparalleled for an ultra-high voltage (154 kV) transmission line.” The completed wind farm is designed to have a total output of 121,600 kW, which would make it the largest onshore wind farm in Japan.
The wind farm, located in Tsugaru City, in the Aomori Prefecture, was established by Green Power Tsugaru GK, a group company of Green Power Investment Corporation. Construction took about two and a half years. Sumitomo Electric was in charge of the design, manufacturing and installation of electrical equipment, such as underground power transmission and distribution lines and substation equipment, jointly with its group companies, Nissin Electric Co., Ltd. and Sumitomo Densetsu Co., Ltd.
