ENGIE develops geothermal technologies to produce electricity, for example in Indonesia, on the island of Sumatra which, with its 140 active volcanoes, has the highest geothermal potential on the planet and accounts for 40% of worldwide reserves.
Drilling started in 2012 and confirmed the existence of a high-temperature reservoir (hotter than 200°C).
In December 2019, ENGIE started operating the first 85-MW electricity power plant in Muara Laboh as part of a three-party consortium, made up of the Japanese Sumitomo Corporation trading and investment company, the Indonesian geothermal electricity project developer, PT Supreme Energy, and ENGIE.
A second electricity power plant is under construction on a new site in Rantau Dedap, which is due to start up in 2021.
The 85-MW Muara Laboh power plant is already producing geothermal electricity that will supply about 340,000 households for more than 30 years.
The second power plant in Rantau Dedap should produce 90 MW of electricity.
