Chubu Electric subsidiary Ctech is on track to expand its portfolio of wind farms in the Aoyama Kogen region of Mie Prefecture from the current 31 MW to 149 MW, with a long term target of 200 MW. The firm says it is conducting an environmental assessment at the 15 MW Aoyama-Kogen Wind Farm, where it is the leading shareholder, with a view to adding 40, 2 MW turbines. It has not yet chosen a supplier. With a capacity of 95 MW, the plant would eclipse Japan's largest existing wind farm, J-Power's 66 MW Koriyama Nunobiki Kogen project in Fukushima Prefecture. The expansion at Aoyama-Kogen is to start in late 2010, with operation in 2016. Next year, Ctech will begin installing turbines at its 38 MW Wind Park Kasatori, with the first ten turbines beginning operation in February 2010 and nine remaining machines turning in early 2011. Japan Steel Works will supply the 2 MW machines.
