China Three Gorges Corp, the world's biggest hydropower builder, will further diversify its business into wind, solar, and other forms of new energy beyond its core business.

The Beijing-based hydropower company will boost construction of offshore wind power farms both at home and abroad, said Wang Feng, vice-president of CTG Europe, the European branch of CTG, the builder and operator of the world's largest hydropower project Three Gorges Dam.

The company is taking a fresh step in the European clean energy market after purchasing an 80 percent stake in a 288 megawatt offshore German wind farm operator, WindMW from US private equity firm Blackstone Group for around $1.8 billion, which CTG described as one of the most promising offshore wind businesses in Europe.
