In October 2012, Sumitomo Corporation (Head Office: Chuo-ku, Tokyo; President and CEO: Kuniharu Nakamura) completed construction of the Ulubelu geothermal power station comprising units 1 and 2, each with a capacity of 55 megawatts (MW), for delivery to PT. PLN (Persero) (hereafter, “PLN”), a state-owned power company in Indonesia.
Located in the Ulubelu district, Tanggamus county in Lampumg Province at the southern tip of Indonesia’s Sumatra Island, the Ulubelu power station was built as the first large-scale geothermal power generating facility on the island. The construction project was financed with a yen credit loan from the Japanese Government. Sumitomo Corporation received an order from PLN to undertake the Ulubelu power station construction project through international bidding in 2010. The project was completed after two years, ahead of the deadline set in the contract with PLN.
