Start of power generation of Matsuura Power Station Unit 2 -Start of power generation with the trial run starting on June 1, 2019-
Kyushu Electric Power has been working on civil engineering, construction and equipment installment of Unit 2 of the Matsuura Power Station situated in Matsuura-shi, Nagasaki Prefecture since January 2016. We are pleased to announce that this power plant will start generating power as part of its trial run starting tomorrow.
Output will be gradually increased, and safety inspections, equipment adjustment and performance tests according to the law will be conducted, aiming for the start of commercial operation in December 2019.
Industry-leading technology is used in Matsuura Power Station Unit 2 which reduces the plant's environmental burden and allows the plant to respond flexibly to fluctuations in renewable energy output.
Kyushu Electric Power will continue to build a balanced electricity supply system that harnesses the characteristics of all power sources from an S (safety) + 3E (energy security, economic efficiency, and environment) perspective.
