The Rantau Dedap geothermal power plant development project in Muara Enim regency, South Sumatra, has begun its exploitation phase, marked by the drilling of its first geothermal well, the RD-I3.
The drilling of the well on Aug. 4 was witnessed by the Energy and Mineral Resources Ministry’s director general for new and renewable energy, Rida Mulyana, as well as its geothermal director, Ida Nuryatin Finahari.
The ministry has made geothermal energy one of its top national priorities in the energy sector, maximizing Indonesia’s massive geothermal energy potential, which amounts to 28.5 gigawatts. Currently, the installed geothermal power plants in Indonesia have a total capacity of around 1,948.5 megawatts, making the country the second biggest geothermal energy producer in the world after the United States.
The ministry has approved PT Supreme Energy Rantau Dedap’s request to proceed with the power plant construction’s exploitation phase. Its approval, which was issued in March, takes into consideration the fact that the company has already completed its exploration phase, which it conducted from 2010 to this year, comprising a geosciences survey, infrastructure construction and the drilling and testing of six exploration wells as well as submitting feasibility study reports to the ministry.
