OVERVIEW

In 2001 Hitachi, Ltd. and Babcock-Hitachi K.K. were contracted by EPCOR Power Development Corporation of Alberta, Canada to oversee the engineering and construction of Genesee Power Generating Station Phase 3, a 495-MW-capacity coal-fired power plant that is scheduled to become operational in the first quarter of 2005. This paper presents an overview of the Genesee Phase 3 project. Given the relative abundance and low cost of coal in the province of Alberta, it was decided early based on economic and environmental considerations that the new third unit would employ supercritical-pressure pulverized coal combustion technology. In addition to the high efficiency supercritical-pressure boiler and turbine, adverse impact on the environment is minimized through the use of low nitrogen oxides (NOx) burners, a dry FGD (flue gas desulphurization) unit, and a high-efficiency dust-collection system using a fabric filter baghouse. Based on a proven track record in building a number of supercritical coal fired plants, Hitachi, Ltd. and Babcock-Hitachi K.K. will execute all EPC (engineering, procurement, and construction) enabling seamless integration between the boiler and turbine. In addition, much of the design detail is based on a 500-MW reference plant, thus enabling the plant to be substantially completed in the first quarter of 2005.
