MHPS Receives Order for Boiler, Steam Turbine and Generator For the Philippines' First Ultra-supercritical-pressure Coal-fired Power Plant
Yokohama, December 9, 2015 -- Mitsubishi Hitachi Power Systems, Ltd. (MHPS) has received an order for a boiler, a steam turbine and a generator for the San Buenaventura Power Plant, a 500 megawatt (MW) ultra-supercritical-pressure (Note) coal-fired power generation plant to be built by San Buenaventura Power Ltd., a special purpose company (SPC), in the Philippines. MHPS will supply the equipment through Daelim Industrial Co., Ltd. of Korea, the company selected to perform engineering, procurement and construction (EPC) of the plant. Daelim received the order to construct the plant, which will start commercial operation in June 2019, jointly with Mitsubishi Corporation (MC).
The San Buenaventura Power Plant, the Philippines' first ultra-supercritical-pressure coal-fired power generation plant, will be built on the site of the Quezon Power Plant operated by Quezon Power (Philippines), Limited Co. in the municipality of Mauban, Quezon Province, approximately 100 kilometers east of Manila, the capital. The plant will use subbituminous coal imported from Indonesia. Based on a long-term power purchase agreement, the power produced at the plant will be supplied to Manila Electric Company (Meralco), the Philippines' largest electric utility company, to meet robust demand in the region.
San Buenaventura Power is a SPC jointly established by two power producers: the Electricity Generating Public Company Limited (EGCO) of Thailand and Meralco PowerGen Corporation (MGEN), a power generation affiliate of Meralco. MC and Tokyo Electric Power Company, Incorporated (TEPCO) each own a 12.286 percents share of EGCO.
MHPS has technological expertise in the design and manufacture of boilers capable of using a variety of coal types as their fuel. By combining the company's boilers with environmentally compatible burners built on strong operational track records and high-performance mills that can employ various coal types, it is possible to achieve highly efficient power generation while simultaneously reducing emissions of nitrogen oxides (NOx) and carbon dioxide (CO2).
Leveraging its advanced technologies, going forward MHPS intends to further strengthen its marketing activities in regions where demand for coal-fired power generation system is expected to grow: e.g., Southeast Asia (including the Philippines), Eastern Europe, Latin America and Africa. By flexibly responding to the various types and properties of fuel resources available in each region, MHPS will contribute to stable supplies of electricity and reduction of environmental burdens in countries and regions around the world.
- Under normal atmospheric pressure (1 atm), water boils at 100°C (212°F/373°K) and the temperature and pressure go no higher. When increased pressure is applied, however, the boiling point rises beyond 100°C; and if pressure is increased further and takes the water temperature to 374°C/22.12 megapascals (approx. 220 atm), water no longer boils but rather vaporizes. This is referred to as water's critical point. Supercritical pressure is defined as the state above critical point; and ultra-supercritical pressure refers to the state when water's temperature rises to 593°C. In recent years, owing to their enhanced power generation efficiency, demand has been increasing for supercritical-pressure and ultra-supercritical-pressure boilers and steam turbines.
