Huaneng Renewables Corporation Limited provided earnings guidance for the six months ended June 30, 2012. Based on the preliminary estimate by the Company, it is expected that the net profit attributable to the shareholders of the Company under the International Financial Reporting Standards for the period from 1 January 2012 to 30 June 2012 may decrease by more than 50%, compared to the corresponding period last year. The decrease of more than 50% of the net profit attributable to the shareholders of the Company for the period from 1 January 2012 to 30 June 2012 was mainly due to (1) intensified electricity output constraints in some regions and decrease of wind speed as compared to same period in previous year; and (2) decrease in the market price of Certified Emission Reductions.
