Project Description

According to ADB website, the project will develop geothermal steam resources through production and injection facilities in the Liki Pinangawan Muaralaboh concession area and construct, operate, and maintain a single power generation unit with a total capacity of approximately 80 megawatts (MW). The concession is located in the South Solok Regency, 150 kilometers (km) southeast of Padang, West Sumatra. The project will be developed and implemented under a 30-year power purchase agreement (PPA) with PLN (the off-taker) and a 20-year support from the Ministry of Finance, as stipulated under a business viability guarantee letter (BVGL). It is intended for base load operation. PLN will build 80 km of transmission lines from the plant site to two 150 kilovolt (kV) substations near Muara Laboh and Sungai Rumbai. The substations will connect power from the generation unit to the Sumatra grid through an existing 275 kV transmission line.
