Électricité de France (EDF) has awarded ANDRITZ a contract to supply a new pump turbine and associated equipment for the modernisation of the Vouglans/Saut-Mortier pumped storage project in France’s Jura region.
The contract, valued in the lower double-digit million-euro range, covers the supply of a 17MW variable-speed pump turbine and associated equipment. ANDRITZ said the order was included in its order intake for the second quarter of 2026.
The project will convert the existing hydropower cascade on the Ain River into a three-basin system linking the Coiselet, Saut-Mortier and Vouglans reservoirs.
The addition of the new pump turbine is expected to increase the total generating capacity of the Vouglans/Saut-Mortier scheme by around 80MW to 85MW. Energy storage capacity will increase from 50GWh to 250GWh.
According to ANDRITZ, the modernisation will make better use of the existing infrastructure while increasing the usable water volume, taking ecological and territorial requirements into account.
Under the contract, ANDRITZ will be responsible for the design, manufacture, assembly, commissioning and turbine governor for the pump turbine.
Consortium partner Ingeteam will supply the motor generator and full power converter for variable-speed operation.
Project execution is scheduled to run from 2026 to 2031.
