Huaneng Power International, Inc. provided earnings guidance for the year ended December 31, 2012. For the year, the company expects that based on the preliminary expectations by the company, the annual net profit attributable to the company's shareholders in 2012 as compared to the same period last year is expected to increase by more than 340%. The expected profit increase was primarily due to the carryover effect of the tariff adjustments in 2011, the decrease of coal price in 2012 and the effective cost controls by the company.
