The approximately JPY500bn ($4.4bn) expansion project involves addition of two high efficiency ultra-supercritical coal-fired units, each with 1,000MW capacity, in an area adjacent to the existing 2,640MW Tanjung Jati B coal-fired power plant in Central Jawa, Indonesia.
The existing Tanjung Jati B coal-fired power plant, which comprises four units, is running as a base-load power plant supplying 11% 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.
The expansion project, which is a build, operate and transfer (BOT) scheme, is expected to help the country meet the increasing energy demand.
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.
Earlier, MHPS delivered two boilers for the units 3 and 4 of the power plant which were commissioned in 2011 and 2012 respectively.
Sumitomo said re-expansion project is scheduled to be completed and enter service in 2021.
In order to meet the increase power demand, the country is implementing an initiative to boost its installed power generation capacity by 35,000MW by 2019.
