    Gas turbine combined cycle-thermal power generation systems (hereinafter referred to as GTCC) are the most efficient and clean power generation systems using fossil fuels. New technology development is always moving forward to achieve higher efficiency and lower environmental impact. On the other hand, the operation of the latest high-efficiency GTCC power plants reduces opportunities for the operation of existing power plants, leading to deterioration in the profitability of existing power plant operating companies and a reduction in plant service life for existing power plants. To cope with this situation, Mitsubishi Hitachi Power Systems, Ltd. (MHPS) is retrofitting the technology developed for new types of GTCC power plants to existing power plants and is developing an upgrade menu to meet various requirements from existing power plant operating companies. In order to apply the latest gas turbine technology to existing power plants, it is necessary to upgrade and modify peripheral equipment associated with the power plants. MHPS is also involved in the design and construction of new plants as an EPC business and the development of control equipment. Taking advantage of its comprehensive capabilities, MHPS can propose an appropriate modification scope for the entire power plant and provide a comprehensive range of services, including construction and commissioning.
