P
ower producer PT Supreme Energy announced on Monday that the Rantau Dedap I geothermal power plant (PLTP) in South Sumatra had begun commercial operations.
The power plant has been operating since Dec. 26, 2021, with a capacity of 91.2 megawatts (MW). State electricity company PLN will provide a transmission network to distribute plant electricity to consumers.
PLTP Rantau Dedap is operated by PT Supreme Energy Rantau Dedap (SERD) — a joint venture between Supreme Energy, French utility company ENGIE and Japanese firms Marubeni and Tohoku Electric Power. SERD began exploration of the Rantau Dadap site in 2008.
“Rantau Dedap is a tremendously challenging project because of its location and construction that took place amid the COVID-19 pandemic,” said Supreme Energy founder Supramu Santosa in a press statement.
He went on to say that the project was located in remote, steep highlands with an elevation of 2,600 meters above sea level. The power plant sites are located in three administrative areas, namely Muara Enim regency, Lahat regency and Pagar Alam city in South Sumatra.
The total investment for the first phase of development of the Rantau Dedap power plant was more than US$700 million, the statement noted.
