Kyushu Electric Power Company Starts Commercial Operation of Matsuura Power Station Unit 2 -Largest in scale in Japan as a single unit with 1GW of output-
Today, Kyushu Electric Power Company's Matsuura Power Station Unit 2 started commercial operation having completed its autonomous pre-service inspection pursuant to the Electricity Business Act. It had started generating power as part of its commissioning in June of this year.
Matsuura Power Station Unit 2 uses coal, a resource that is economical and can be procured stably, as its fuel and has adopted the latest technology to increase generation efficiency and emit less CO2.
It is also able to respond flexibly to changes in output from renewable energy sources.
Kyushu Electric Power Company will continue to contribute to realizing a low-carbon sustainable society as declared in the "Kyuden Group Management Vision 2030" by continuing to manage a balanced energy mix from a "S (safety) + 3E (energy security, economic efficiency, environment) perspective.
[Overview of Matsuura Power Station Unit 2]
| Unit 2 | [Reference] Unit 1 （Started operations in June 1989） |
|
| Location | 2091-1, Kaihatsu, Shirahamamen-aza, Shisa-cho, Matsuura-shi, Nagasaki | |
| Output | 1GW | 0.7GW |
| Fuel | Coal | |
| Generation method | Ultra-supercritical*1 pulverized coal fired | Supercritical*2 pulverized coal fired |
| Generation efficiency*3 (Based on lower heating value) |
Approx. 46％ | Approx. 43％ |
| *1： | Increased the temperature and pressure of the generating steam to increase generation efficiency (temperature: exceeding 566℃. pressure: 22.1 MPa or more) |
| *2： | Temperature of generating steam: 566℃ or less; pressure of generating steam: 22.1MPa or less |
| *3： | Generating efficiency based on lower heating value is calculated by subtracting the amount of heat in the combustion gas steam |
