Huaneng Power International, Inc. Power Generation Within China Decreases by 2.44% in the First Quarter of 2013

BEIJING, April 12, 2013 /PRNewswire/ -- Huaneng Power International, Inc. ("HPI" or the "Company") (NYSE: HNP; HKEx: 902; SSE: 600011) today announced its power generation in the first quarter of 2013.

According to the Company's preliminary statistics, as of March 31, 2013, the Company's total power generation within China on consolidated basis amounted to 74.306 billion kWh, representing a decrease of 2.44% over the same period last year. Total electricity sold by the Company amounted to 70.205 billion kWh, representing a decrease of 2.25% over the same period last year.

The decrease in power generation of the Company was mainly attributable to the following reasons:

1. As the domestic power demand stayed low in the first quarter of 2013, nationwide thermal power generation saw only a slight increase of 0.87% for the first quarter of 2013, with negative growth in southeast coastal areas and modest growth in other regions. In Gansu and Yunnan, hydropower output increased considerably which affected the rate of growth in the thermal power sector. Since the Company's installed capacity is mainly fuelled by thermal power generators and distributed in southeast coastal areas, the electricity generated by the Company experienced decrease over the same period last year.
2. The Company has no cogenerating units in Hebei, Shanxi, Henan and Gansu. The increased cyclic non-operation of non-cogenerating units of the Company during the heating season had affected our output of electricity in these areas.

The power generation and electricity sold by each of the Company's domestic power plants in the first quarter of 2013 are listed below (in billion kWh):

The accumulated power generation of Tuas Power Limited in Singapore accounted for a market share of 20.5% in Singapore in the first quarter of 2013, representing a decrease of 6.1 percentage points compared to the same period last year.

In addition, the project on "replacing smaller generating units with large generating units" at Zhejiang Huaneng Changxing Power Plant (which is wholly-owned by the Company) (the "Project") was recently approved by the National Development and Reform Commission. The Project will be constructed with two 660 MW ultra-supercritical coal-fired generating units. The dynamic total investment of the Project is estimated to be approximately RMB5.662 billion, of which 20%, being the project capital, will be funded by the Company by its internal fund. The remaining investment will be funded by bank loans.

Moreover, Units No.3 (1,036 MW) and No.4 (1,036 MW) at Guangdong Huaneng Haimen Power Plant (in which the Company owns 80% interest) has completed trial run recently. In addition, there has been adjustment to the generation capacity of certain generating units of the Company. To date, the Company's total controlled generation capacity has increased to 65,959 MW, and equity-based generation capacity has increased to 58,961 MW.
