Japan’s Sumitomo Corporation has commenced construction of the Tanjung Jati B coal-fired power plant expansion project in Indonesia.

The works are part of an overall government initiative to boost the country’s installed power generation capacity by 35,000 MW by 2019.

Sumitomo, Kansai Electric Power and PT United Tractors are all involved in the $4.4bn development of the unit 5 and 6 expansion project, which will see the addition of two high efficiency ultra-supercritical coal-fired units, each with 1,000 MW capacity, in an area adjacent to the existing 2,640 MW Tanjung Jati B coal-fired power plant in Central Jawa.

The existing Tanjung Jati B coal-fired power plant, which comprises four units, is running as a base-load power plant supplying 11 per cent of electricity in Jawa-Bali Grid system.

Upon completion, the plant will supply power to Indonesian power utility company PT PLN (Persero) under a 25-year purchase agreement.

Meanwhile, Mitsubishi Hitachi Power Systems (MHPS) has been awarded a contract to supply two ultra-supercritical-pressure boilers and four electrostatic precipitators for units 5 and 6 of the Tanjung Jati B power plant.

Sumitomo said re-expansion project is scheduled to be completed and enter service in 2021.
