Renewable energies
and energy performance

Our specialised energy generation and maintenance business lines design cuttingedge technical solutions, including wind farms, photovoltaic plants, geothermal installations, co- and tri-generation plants, biomass power plants, and wastetoenergy facilities.

Rising to meet the energy challenges of our time

To meet the current energy challenges and in accordance with the targets set by the European Union, which aims to increase its total energy consumption from renewable sources to 20% by 2020, the Group has led the way in developing alternatives to fossil fuel energies in France and beyond. It is also focusing on making energy savings and reducing its greenhouse gas emissions. 

Smartseille and the seawater loop


The seawater loop set up for the Smartseille eco-neighbourhood in Marseille alongside our partner EDF Optimal Solutions represents a major innovation. The novel heating and cooling solution pumps in seawater from a medium depth near the city’s port facilities and uses it to provide the balance needed to operate its internal warm water network for the neighbourhood. Thanks to this innovative system, which provides a natural source of heating or cooling depending on the season, 75% of the energy used by the Smartseille eco-neighbourhood comes from renewables. 

Energy-efficient buildings for a high-quality user experience

At the beginning of March 2018, Eiffage Énergie Systèmes presented its digital energy monitoring system for public buildings, the first of its kind in Europe. The Group is building a monitoring system for the city of Paris that will be the most extensive in Europe. It will install smart sensors at the city’s various thermal plants to collect data and spread demand for energy as evenly as possible. A special network employing Internet of Things (IoT) technology collects and uses this data. The system will optimise the city’s energy management and pave the way for the creation of new services and applications for users. In addition, Eiffage Énergie Systèmes sealed an energy performance contract with the CentreVal de Loire region in 2010 to operate the energy installations at 19 high schools for 15 years. Eiffage Énergie Systèmes will maintain and manage the schools’ energy performance until the contract expires. 


Co-generation plant: power plant generating two different forms of energy simultaneously. For example, electrical energy and thermal energy can be generated simultaneously from a single energy source. 

Tri-generation plant: works along the same lines, but generates three different forms of energy, adding a third energy in a cold form, to electrical energy and thermal energy. That helps to simultaneously create electricity, heat and cooling.
