Entech secures its largest EPC contract: a 40 million euro battery facility

A 90 MW / 180 MWh facility connected to the RTE network

The contract covers the turnkey construction of a battery energy storage system (BESS) with a capacity of 90 MW and a storage capacity of 180 MWh. The client is an electricity producer operating in mainland France, whose identity has not been disclosed. The scope also includes the construction of the associated high-voltage substation (HTB). This facility will enable the connection of the battery plant to the 90 kV electricity transmission network managed by RTE.

Entech will manage the project alone, from design to commissioning

The contract value amounts to approximately 40 million euros. As the sole EPC contractor (engineering, procurement, construction), Entech will ensure overall project management until commissioning. This mission covers the performance of preliminary studies, the selection of subcontractors and the monitoring of all works. According to the press release, this organizational approach meets the client's desire to have a single point of contact. The operational phase of the facility will be accompanied by a 5-year renewable maintenance contract (O&M).

Management highlights the group's financial capacity

For Christopher Franquet, presented as CEO of Entech, "this contract is part of our client's BESS project development strategy and aims to support the continued growth of flexible energy solutions in France". He adds that the operation "illustrates Entech's growing momentum and its capacity, both technically and financially, to independently manage projects of increasingly significant scale". The group's next financial milestone is scheduled for February 23, 2027, with the publication, after market close, of the consolidated annual revenue for 2026.
