Against a background of fossil fuel depletion and soaring prices, geothermal offers encouraging prospects for controlled energy costs in the medium to long terms. Still a low-profile technology at present, geothermal is defined as a renewable, local and eco-friendly source of energy that is simultaneously efficient and economical. It shows considerable potential for heat and power generation.
ENGIE develops its geothermal interests in France and worldwide
100 GWh de of green heat for 10,000 housing units.
ENGIE is providing 100 GWh of green heat to households in the towns of Champs-sur-Marne and Noisiel, in the Paris region. Employing at least 80% geothermal energy, this is a 25-year public service delegation contract with the Paris-Vallée de la Marne conurbation authority (CAPVM) for the construction and operation of a 20 kilometer-long heat network. The new network will contribute to the decarbonization of this estate and will give green credentials to buildings that will be constructed in this territory in the future. The network will also help combat energy insecurity by guaranteeing affordable and stable prices for future users.
- 80% of geothermal energy in the network
- 100 GWh of green heat, equivalent to the needs of 10,000 housing units
- Around 96 GWh of energy consumption by 2030
Indonesia: first power plant under construction
ENGIE is also developing geothermal technologies for power generation. The initial experiments are being conducted in Indonesia. With 140 active volcanoes, this country offers the highest level of geothermal potential on the planet, with 40% of global reserves.
The first drilling projects undertaken in 2012 and 2013 by ENGIE/Sumitomo Corporation joint venture PT Supreme Energy Muara Laboh (SEML) at Muaralaboh in Western Sumatra have confirmed the existence of a high-temperature reservoir (above 200°C).
ENGIE is also conducting a geothermal exploration project at Rantau Dedap, 225 km from the South Sumatran provincial capital of Palembang. The concession was granted to the consortium formed by ENGIE, PT Supreme Energy and Marubeni. With a target capacity of 240 MW, the project is expected to generate geothermal power for more than 30 years, supplying the electricity needs of some 480,000 households and reducing carbon dioxide emissions by around 1.1 million metric tons per year. ENGIE also has two other geothermal exploration projects in Indonesia: one at Muaralaboh in Western Sumatra, and the Rajabasa project at the Southern tip of the island.
