Harbin Power Equipment's order book swelled by 30 billion yuan last year on the back of the mainland's power plant construction boom, but growth next year and in 2007 could be pared by the central government's clamp-down on unapproved projects. Harbin Power Equipment chairman Geng Lei said the company received 40 billion yuan of new orders in 2003 and 30 billion yuan last year as companies raced to build plants to meet the nation's voracious power demand. The firm booked 5.14 billion yuan of turnover in 2003 and 3.81 billion yuan in the first half of last year. But Beijing's recent campaign to stamp out power projects that are not economically or environmentally viable has cast a cloud over the equipment industry. 'Since the majority of our customers are the five national power generation groups and reputed firms like China Resources Power Holdings, I think the impact on us will not be major,' Mr Geng said. He said the company was still calculating the possible impact of higher iron ore prices and higher steel prices on its operations.
