German wind energy developer and operator ENOVA Power has started construction work on the repowering of Hiddels wind farm in the Friesland district of Lower Saxony, the company announced. The project will deliver a total capacity of 30 MW and is one of the company’s next major development schemes in the Weser-Ems region.
The repowering involves first decommissioning eleven existing turbines installed between 2000 and 2002 — nine Enercon E-66 units and two Vestas V66 units — followed by the installation of five Vestas V150 turbines, each rated at 6 MW. The new installations are expected to begin generating electricity in the second half of 2027, with a projected output sufficient to supply around 20,500 two-person households with renewable electricity. ENOVA is also investing in grid infrastructure at the site by constructing a dedicated substation to provide direct, independent grid access.
“With the construction start at Hiddels, we are advancing another repowering project in our core region on schedule,” said Fabian Tews, Lead Project Management at ENOVA. “At the same time, this demonstrates the potential of modernising existing sites through new turbine technology and optimised grid connection: we are increasing capacity at the site by a factor of 1.6.”
ENOVA acquired the Hiddels wind farm, including its repowering permit, in December 2024 from a limited partnership fund. The Projekt Ökovest GmbH is co-operating on the project and will operate one of the new turbines, and is also overseeing coordination and monitoring during the construction phase.
ENOVA, which manages 1 GW of operational wind capacity and currently supplies around one million households with renewable electricity, has set a target of reaching 3 GW under management and €5 billion in assets under management by the end of 2030.
