Summary of our market study

The global geothermal market has been on an upward trajectory, with forecasts predicting a significant increase in production capacity from 92 TWh to 282 TWh by 2030.

The United States remains the leading producer, with 18.8 TWh of geothermal energy in 2018, closely followed by Indonesia and the Philippines.

In France, geothermal energy is a high-potential market that remains largely under-exploited. The Bouillante power plant in Guadeloupe is a notable producer, contributing 110 GWh, or 6% of the island's energy output.

The Soultz-sous-Forêts project in Alsace has a production capacity of 1.7 MW (12 GWh per year), and other regions such as the Massif Central and Languedoc-Roussillon have additional potential.

Despite a slight increase in recent years, geothermal energy's share of heat and power production in France remains below that of conventional energy.lectricity in France remains below 5% and 4% respectively, with a production potential of over 3,000 MW for geothermal electricity.

The regulatory framework is evolving, and the government's 2023 action plan strongly supports the development of geothermal energy, notably by increasing financial incentives for geothermal installations.incentives for geothermal installations, targeting a 40% increase in deep geothermal projects by 2030 and doubling the number of geothermal heat pump installations by 2025.

Geothermal energy in France: untapped potential

The French geothermal market is characterized by significant but under-exploited potential. The French geothermal market is rich in opportunities. It generates between 10,000 and 20,000 jobs.

Geothermal energy accounts for less than 4% of heat production in France. It holds a significant share of the country's electrical potential, estimated at over 3,000 MW, which could cover around 90% of the national territory.

Geothermal installations provide heating, hot water and cooling for over 1.2 million French residents, equivalent to around 1.8% of the total population.

Heating dominates household electricity expenditure, accounting for over 60% of total electricity costs in 2022.

The heat pump market plays a major role in geothermal energy demand. It is showing strong growth, with a 30% increase in sales of air-to-water heat pumps and a 7% rise for geothermal heat pumps between 2021 and 2022.

Heat pumps account for 12% of French renewable energy production. This contribution is set to rise to 34% by 2035, and almost 50% by 2050.

Geothermal energy falls into two categories: shallow geothermal on the one hand, and deep geothermal on the other, the latter including both hydrothermal and advanced systems exploiting higher temperatures between 200°C and 600°C.

Installation costs naturally vary according to the complexity of the technology, and for a typical shallow geothermal installation, you can expect to spend around €19,600.


The main players in the French geothermal energy market

  • Among the historical suppliers, Électricité de France (EDF) dominates the electricity generation landscape.
  • Local distribution companies (ELD) are regional entities within the market, responding to specific local energy needs and playing an important role in their respective territories.
  • Alternative suppliers such as Engie and TotalEnergies, companies that have diversified into renewable energies and geothermal energy.
  • Réseau de Transport d'Électricité (RTE), the transmission system operator, ensures that the electricity generated, including from geothermal sources, flows efficiently and reliably on the high-voltage transmission grid. A subsidiary of EDF, RTE plays a crucial role in balancing the national grid and facilitating the integration of renewable energies.
  • Enedis, the distribution network operator, oversees the delivery of electricity to end-users via a vast network of lines and substations.
  • Local distribution companies in various regions ensure that electricity, whatever its source, remains accessible to even the most remote customers.

Summary and extracts

1 Market overview

1.1 Introduction

Geothermal energy is the use of the natural heat of the ground or groundwater as a means of heating or producing energy (mainly electricity). Collectors are buried in the ground and connected to a boiler to generate constant heat for heating a home in winter and cooling it in summer. At a depth of 60 cm, for example, the ground temperature is a constant 14°. There are several different types of geothermal energy : shallow, low-temperature geothermal energy, deep, high-temperature geothermal energy and very deep, high-temperature geothermal energy. There is also high-energy, low-energy and very low-energy geothermal energy.

Geothermal energy accounts for less than 4% of heat production in France and 5% of electricity production. France's potential for geothermal energy production is over 3,000 MW of geothermal electricity, which is a significant figure ; 90% of the country could be covered by surface geothermal energy. This market brings together around a hundred companies in France and over 15,000 jobs in energy companies and geothermal specialists.

Despite tax credits, the geothermal market is slow to take off in the residential sector (whereas it was booming in the was booming in the 1970s, it came to a halt with the fall in oil prices in the 1980s). Nevertheless, in 2022, the geothermal heat pump market is up 7% on 2021, and the upturn in the new housing market could boost this market segment over the next few years.

In 2023, against a backdrop of rising electricity and hydrocarbon prices, geothermal energy will become an alternative to traditional energy sources, and the government has launched an ambitious plan to promote this still little-known energy source.
