China Gezhouba Group Co., Ltd (CGGC), a leading state-owned enterprise of infrastructure construction in the country, has signed a 4.97 billion yuan (727.78 million U.S. dollars) contract with a Kazakhstan company on a hydropower project, said CGGC Thursday.

In a statement to the Shanghai Stock Exchange, CGGC said the contract with Kazakhstan Natural Gas Technology Co., Ltd. will allow it to construct a hydropower station, with an installed capacity of 254 megawatts, on the Chilik river in Alma-Ata, Kazakhstan.

The project will last 57 months.

Given that the contract is a long-term one, CGGC predicts little influence on its net profit in 2010. According to the statement, the contract is yet to be approved by either government.

Shares of the CGGC opened slightly lower at 13.41 yuan per share, up 1.13 percent compared with Wednesday's close.
