Signed a Medium-to-Long Term Coal Supply Agreement with Shenhua Coal Trading Company (Beijing, China, July 26, 2004) Huaneng Power International, Inc. (the "Company") [NYSE: HNP; HKEx: 902; SSE: 600011] has signed the "Year 2005-2007 Coal Supply Agreement" (the "Agreement") with Shenhua Coal Trading Company ( "Shenhua Coal" ) today. Pursuant to the Agreement, Shenhua Coal will be providing to the Company with high-quality thermal coal amounting to 9 million tonnes, 10.5 million tonnes and 11 million tonnes for the years of 2005, 2006 and 2007 respectively. After amicable discussion under the principle of taking up mutual responsibility vis-a-vis market risks, a basic price was set with the guarantee that any annual increase/decrease would not exceed by 5%. Prior to the Agreement, the two parties have already concluded and signed another agreement on increasing allocated coal supply by 1.5 million tonnes to the Company by Shenhua Coal in the second half of 2004. The annual coal yield of Shenhua Group Co. Ltd. is 120 million tonnes. Currently, it is one of the largest coal suppliers in the PRC and Shenhua Coal is its wholly-owned subsidiary. Throughout the years, Shenhua Coal and the Company have been maintaining good relations regarding coal supplies and other business aspects. In view of the difficult market situations regarding coal supply, electricity demand and transportation, both parties have been working hard on the principles of integrity and mutual benefits with an aim to resolve the problem of power supply shortage during the peak summer season. The cooperation between the two parties exemplifies an excellent operation of a medium-to-long term agreement on coal supply to power companies. The signing of the Agreement is also consistent with the State's objectives and policies in promoting market mechanisms in thermal coal supply. Huaneng Power International, Inc. develops, constructs, operates and manages large thermal power plants in China nationwide, with a total generation capacity of 18,832MW on an equity basis. The Company wholly owns sixteen power plants, and has controlling interests in seven power plants and minority interests in four power companies.
