KEPCO–SPC Power Corporation (KSPC), a joint venture between KEPCO Philippines Holdings (a wholly-owned subsidiary of Korea Electric Power Corporation or KEPCO) and SPC Power Corporation, is developing the Visayas Base Load Power Project. The Project is located in Colon barangay (district) of Naga, in the province of Cebu (Map 1). It was conceptualized under a new scheme of a merchant power plant, on a build–own–operate basis, characterized by the execution of power sales contracts with distribution utilities and electric cooperatives, instead of purchase power agreements with the Government of the Philippines. Under this concept, the generating company is responsible for the whole construction, operation, and maintenance of the plant, including fuel supply—without any Philippine government guarantees. 2. The project area covers 8.4 hectares (ha) that were previously utilized as an ash pond of the existing Naga power plant complex, operated by SPC Power Corporation. The Project will construct a coal-fired power plant utilizing circulating fluidized bed combustion (CFBC) 1 technology—a clean coal technology with more 1,300 units operating worldwide. The plant will consist of two 100 megawatt (MW) units, which will utilize coals from PT Kasih Industri and PT Surya Sakti Darma Kencana (both in Indonesia) and qualified local suppliers. 3. Completed project milestones include the signing of the engineering, procurement, and construction (EPC) contract with Doosan Heavy Industries & Construction on 10 December 2007, excavation on 14 February 2008, and boiler steel structure erection on 10 December 2008. The overall construction accomplishment status for EPC as of 31 December 2008 had reached 31.5%. The target for commercial operation is February 2011 for the first 100 MW and in May 2011 for the second 100 MW. 4. This summary environmental impact assessment was prepared by KSPC for use by the Asian Development Bank (ADB) in accordance with ADB’s environmental and social safeguard policies and information disclosure requirements for environmental category A projects. It summarizes and consolidates the major findings and recommendations presented in the environmental impact statement (EIS).2 The environmental compliance certificate for the Project was issued on 5 December 2005 by the secretary of the Department of Environment and Natural Resources (DENR). As part of the EIS, a public hearing was held on 6 August 2005 and further consultations were conducted with local people. II. DESCRIPTION OF THE PROJECT A. Project Facilities 5. The project facilities to be constructed by KSPC include the power plant and support facilities. The main project facilities will include two 100 MW CFBC units, main transformer, switchyard, control system, coal handling system (unloading and stockpiling), ash handling system, electrostatic precipitator, feed water system, condensate system, circulating water system, and closed cooling water system. However, the 1 kilometer (km) transmission line to 1 The power plant will use the CFBC process, one of the better technologies in the type of power plant using coal as fuel. CFBC technology has better efficiency in the regulation of gas emissions—an inherent weakness of coal-fired power plants—making it more environment-friendly and a better alternative to conventional pulverized coal boilers such as the existing power plant in the area.
