Dravske elektrarne Maribor d.o.o. (DEM), Slovenia’s largest renewable energy producer, has awarded international technology group ANDRITZ a contract for the complete refurbishment and modernization of the Formin hydropower plant.
ANDRITZ will supply two new turbines and generators as well as related electromechanical equipment. The order value is in the high double-digit million-euro range and will be included in ANDRITZ’s order intake for the third quarter of 2025.
Commissioned over 45 years ago, the Formin run-of-river plant has a total installed capacity of 116 MW. The modernization will increase its total capacity to 130 MW, ensuring efficient operation for decades to come.
ANDRITZ’s scope includes the design, manufacturing, installation, testing, and commissioning of the refurbished and uprated units, along with associated auxiliaries. The work will be carried out using ANDRITZ’s advanced production facilities in Austria, supported by its global network.
With a total installed capacity of nearly 600 MW and an annual production of 2,800 GWh, DEM’s fleet contributes nearly 25% of Slovenia’s electricity production. Enhancing reliability and output, the Formin upgrade is a key part of DEM’s long-term commitment to sustainability and energy efficiency.
This project marks the first major collaboration between DEM and ANDRITZ. It underscores ANDRITZ’s strong position in the European hydropower market and its expertise in delivering rehabilitation solutions, which play a crucial role in renewable energy generation.
