Overview and Verification Status of T-point Demonstration Facility
Located on the premises of Takasago Works of Mitsubishi Power, the gas turbine combined cycle power plant demonstration facility (T-point) undergoes a long-term verification test for combined cycle power plant facilities while sending the electric power generated to the electric power company.
Purposes of the T-point
- Verification of technologies newly introduced for higher temperatures, higher efficiency gas turbines and lower NOx and other pollutant emissions in the exhaust gas
- Verification of reliability of combined cycle power generation with high efficiency and low environmental impacts through long-term commercial operation
History
The performance test and the durability test of the M501G-Series gas turbines commenced in 1997. The long-term verification test ended successfully.
The total amount of power generation exceeds 1.2 billion kWh (as of 2017). So far, the M501G/GAC have undergone the verification test and a M501J has been in operation since 2011.
Facility Configuration
The T-point consists of a gas turbine with an output of 270 MW and a steam turbine with an output of 119 MW. With a total output of 389 MW, it is a multi-shaft type combined cycle power plant.
Verification of Next-Generation Combined Cycle Power Generation
Mitsubishi Power presses ahead with research and development for next-generation high efficiency combined cycle power plant facilities. To verify its results over a long period of time, a new demonstration facility will be constructed next to the existing T-point.
The new T-point, featuring a single-shaft type combined cycle, is scheduled to reach completion in July 2020.
