Optimizing the building energy mix

As well as supplying natural gas and power, ENGIE also operates local and renewable energy generating resources to offer the best and most efficient energy mix for the needs of individual buildings. This is achieved using a comprehensive range of innovative renewable and local energy solutions, including biomass, biogas, biomethane, marine geothermal, high-temperature solar and hydrogen technologies.


France's first marine geothermal power plant in MarseilleFrance’s first marine geothermal power plant in Marseille

The Thassalia marine geothermal plant in Marseille’s Euroméditerranée business center is an excellent example of how innovation is driving the energy transition and energy efficiency, and one to which Cofely Services has contributed its expertise in heating technology, whilst Climespace, the ENGIE Group specialist in urban cooling networks, has contributed its refrigeration expertise. The 3 kilometers of this energy (heating and cooling) distribution network will meet all the energy needs of the southern section of Euromed 1, and the Constructa H99 and La Marseillaise towers. A total floor area of around 500,000 m2 will be heated by the plant. This should enable the EcoCité to reduce its greenhouse gas emissions by 70% and its water consumption by 65%.
