Indonesia-based energy company PTSERD has announced that the first phase of the Rantau Dedap geothermal power plant in Indonesia has started commercial operations. The first phase of the project has an installed capacity of 91.2MW and has invested more than US$700 million in development. The geothermal facility is located in the cities of Muara Enim Regency, Lahat Regency and PagarAlam in South Sumatra.

Rantau Dedap Geothermal Power Plant

The energy generated by the plant will be transmitted to the grid transmission of PTPLN (Persero) Sumatra to ensure a reliable power supply in the Sumatra region. SERD is a joint venture between PT Supreme Energy, ENGIE, Marubeni Corporation and Tohoku Electric Power. Supramu Santosa, founder and chairman of PT Supreme Energy, said: “The RantauDedap project is the most challenging geothermal project due to its remote location, steep terrain, high elevation and being constructed during the Covid-19 pandemic.

In 2008, PT SupremeEnergy started preliminary studies on the Rantau Dedap power plant and carried out exploration activities until 2015. The company signed a power purchase agreement (PPA) for the project in 2012, which was subsequently amended in 2017. Following the financial close of the PPA in 2018, PT Supreme Energy commenced construction engineering and drilling work during the development phase of the project.

SERD has selected a consortium led by PT Rekayasa Industri and Fuji Electric as the engineering, procurement and construction (EPC) contractor for the Rantau Dedap geothermal power plant. Supreme Energy also operates the Muara Laboh geothermal power plant Unit-1 in West Sumatra. The 86MW power plant has been operating since December 2019.Editor/XingWentao
