CHINA Guodian Corp (stock code: 600795), one of the nation's five biggest electricity generators, plans to sell shares in three of its units, Shanghai Securities News said, citing people it didn't name.

The parent of Shanghai-listed GD Power Development Co plans to list China Longyuan Electric Power Group by 2008, it said. Longyuan Power has 800 megawatts of wind power generation capacity under operation, the report said. The unit plans to double its capacity this year and increase wind generation to 4,000 megawatts by 2010, the report said.

China Guodian is also preparing to offer shares of Yantai Longyuan Electric Power Technology Co, which makes environmentally friendly power equipment, it said, without giving a timetable.

Shares of a newly established unit, Guodian Overseas Power Holdings Ltd, will also be sold to the public.
