Located in Chongxian town, Southeast of Yuhang district in Hangzhou, Hangzhou Blue Sky Natural Gas Power Generation Co., Ltd (“Blue Sky Power Plant”) is a wholly owned gas-fired power plant of the Company and is also a key project of Zhejiang province. The plant was founded in December 2004 and commenced commercial operation in March 2006.

The total installed capacity is 112 MW in a combined cycle gas-steam turbine generation system which consists of two gas turbine generator units, two residual heat boilers and two steam turbines. In 2008, actual utilization hours and volume of power sales amounted to 2,907 hours and 315,161 MWh respectively.

The plant sells its electricity to Zhejiang Electric Power Corporation and its power is transmitted to the Zhejiang provincial grid. On-grid tariff applicable to Blue Sky Power Plant was RMB705/MWh (including VAT) effective from 20 August 2008. In addition, under the long-term supply contract between Blue Sky Power Plant and Zhejiang province Natural Gas Development Company (“Zhejiang Gas Company”) which is responsible for the sale and distribution of natural gas transported into Zhejiang province through the West-East Gas Pipeline, Blue Sky Power Plant will submit the expected demand for natural gas in the coming year to Zhejiang Gas Company for review by the end of each year. The contract purchase price of natural gas is determined according to the price of natural gas at delivery point implemented by Zhejiang Provincial Price Bureau from time to time.

Blue Sky Power Plant is fuelled by natural gas and emits almost no fine particles and sulphur dioxide, and only produce a small amount of nitrogen oxide as compared to coal-fired power plants. The plant also generates less noise and lower carbon dioxide emissions compared to coal-fired power plants. For the same amount of heat, burning natural gas produces about 50% less carbon dioxide than burning coal. Furthermore, compared to traditional coal-fired power plants, Blue Sky Power Plant can be started up and increase electricity generation within a relatively short period of time. Thus, it can supply peak power when there is most demand for electricity from the power grid, and can capture additional power sales when there is sudden increase in demand for electricity.

 

The following table shows certain operating statistics for Blue Sky Power Plant for each of the three years ended 31 December 2008.
