Sumitomo starts to build the Tanjung Jati B power plant (Indonesia)

Sumitomo Corporation, Kansai Electric Power and PT United Tractors have started the construction of their Tanjung Jati B coal-fired power plant expansion project in Central Jawa in Indonesia. Upon completion, the new facility will supply power to the Indonesian power utility company PT PLN within the frame of a 25-year power purchase agreement (PPA). This build, operate and transfer (BOT) project is expected to be completed by 2021.



The project involves the addition of two new ultra supercritical (USC) coal-fired units (Unit 5 and Unit 6) with an expected installed capacity of 1,000 MW each. They will be set up alongside the existing 2,640 MW Tanjung Bati B coal-fired plant in Java, which already includes 4 units.



The plant is currently supplying 11% of the electricity demand in the Java-Bali grid network. Indonesia's power demand is strongly increasing and the country is planning to increase its installed generation capacity by 35,000 MW in 2019.
