To meet their climate change obligations, Japanese utilities Tokyo Electric Power (TEPCO) and Kyushu Electric Power have both recently made carbon credit purchase agreements with Chinese wind project developers. Japan's largest electric utility, TEPCO, is buying all the carbon credits expected from CECIC Wind Power (Xinjiang) Company's 30 MW wind farm in the Wulabo suburb of Urumqi City, Xinjiang Uygur Autonomous Region of China. Each credit is equivalent to one tonne of carbon dioxide (CO2) emissions saved. In all, the project, which is being developed under the Kyoto Protocol's Clean Development Mechanism (CDM), is expected to save 430,000 tonnes of CO2 emissions between September 2007, when the agreement begins, and December 2012, when the deal ends. Commercial operation of the project is scheduled to start this month. It comprises 20, 1.5 MW turbines supplied by China's Dongfang Steam Turbine Works. The deal follows an earlier announcement by TEPCO confirming its agreement with another Chinese firm, Guangdong Yudean Shibeishan Wind Power Development, to buy the carbon credits generated by the 100.2 MW Shibeishan wind farm, as of July. The deal again runs to the end of 2012, with some 970,000 tonnes of CO2 reductions expected from the CDM project until that date. Shibeishan's 167 Goldwind 600 kW turbines are scheduled to start operation this month. Kyushu Electric Power said in April that it and Japanese trading house Sumitomo have entered a joint venture agreement with China Datang Corporation to develop a 50 MW wind plant in Chifeng City, located in China's Inner Mongolia Autonomous Region. Another CDM project, operation is slated to begin in late 2008, Kyushu Electric says. It will purchase the carbon credits associated with the wind farm's generation.
