Huaneng Power International, Inc. Power Generation Within China Decreases by 5.40% for the First Three Quarters of 2012

BEIJING, October 15, 2012 /PRNewswire/ -- Huaneng Power International, Inc. ("HPI" or the "Company") (NYSE: HNP; HKEx: 902; SSE: 600011) today announced its power generation for the first three quarters of 2012.

According to the Company's preliminary statistics, as of 30 September 2012, the Company's total power generation within China on consolidated basis amounted to 223.662 billion kWh, representing a decrease of 5.40% over the same period last year; accumulated electricity sold amounted to 210.916 billion kWh, representing a decrease of 5.33% over the same period last year.

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

1. Affected by the slower economic growth nationwide and the weak demand for electricity, the power generation across the country grew by only approximately 3%. The growth of power generation in the areas where the Company's power plants are located increased by 0.74% on consolidated basis, and the power generation by coal-fired generating plants decreased by over 3.5% on consolidated basis over the same period last year.
2. The average capacity growth rate of the Company for the first three quarters of 2012 was 2.4 percentage points lower than that in the locations where the Company's power plants are situated, which affected the Company's share in the power generation market.
3. During the period from May to September 2012, there had been a rich supply of water to hydropower plants in the provinces and municipalities of Hunan, Jiangxi, Chongqing, Fujian, Gansu and Yunnan, leading to a very high loading rate of hydropower units. In particular, there had been a sharp increase in the hydropower generation provided to Guangdong from Three Gorges, Yunnan and Guizhou. The rise of hydropower generation narrowed the demand for coal-fired power generation in the provinces where hydropower is generated or provided, and significantly affected the Company's generation output.
4. The long-term suspension of the coal mines in the surrounding areas of Yunnan Diandong due to safety accidents in the first quarter of this year resulted in tense supply of coal to the Company's two power plants in Diandong, and affected electricity production of the Company.

The power generation and electricity sold by each of the Company's domestic power plants for the first three quarters of 2012 are listed below (in billion kWh):

The accumulated power generation of Tuas Power Limited in Singapore accounted for a market share of 26.2% in Singapore for the first three quarters of 2012, representing a decrease of 1.3 percentage points compared to the same period last year.
