Eiffage and NGE to support development of two SUEZ waste-to-energy plants

In France, Eiffage and NGE recently jointly signed the contract with SUEZ for the civil engineering of two waste-to-energy plants serving Toulouse and northern Haute-Garonne department. This contract is part of the concession for managing these units awarded to SUEZ and Banque des Territoires by the Decoset Joint Association. The deal is worth a total €132 million (Eiffage 60% and NGE 40%)

The deal agreed with the consortium, led by Eiffage through its subsidiary Eiffage Génie Civil, includes two contracts: 

·      The design-build modernisation of the Bessières waste-to-energy plant, with the works expected to take 16 months, including eight months of studies, for handover in June 2026. 

·      Civil engineering works for the new waste-to-energy plant in Toulouse, with capacity of 240,000 metric tons a year, based on plans created by the two firms of architects Richez Associés and Séquences. This 56-month construction project will be delivered in mid-2031. 

Once commissioned, the two waste-to-energy plants will provide a major boost to energy production, generating more than 220 GWh of electricity per year and more than 360 GWh of heat per year from the residual household waste of over a million people in the region.
