The project is being developed in two phases of 192MW and 269MW and is poised to become Romania’s second-largest wind farm.
The first phase of the project entered trial operations in August 2026, while commissioning of the second phase is expected in summer 2027.
The clean energy generated from the project will be sufficient to power upwards of 270,000 homes, simultaneously offsetting around 540,000t of carbon dioxide emissions each year.
The wind farm is estimated to operate for up to 35 years and will significantly contribute to Romania’s 2030 EU renewable energy targets.
Location
The Vifor wind farm, comprising five sub-projects, is situated within the administrative boundaries of the Costeşti, Gheraseni, Smeeni, Luciu and Ţinteşti communes in Buzau County, south-east Romania.
The wind farm’s substation area, considered the central hub, is approximately 85km north-east of the Bucharest outskirts. The north-western extremity of the wind farm lies roughly 6km from the Buzau city outskirts.
The total area covered by the wind farm spans 2,777 hectares (ha)/6,862 acres, out of which 147.8ha will be impacted by construction, with permanent facilities occupying an additional 44.5ha.
Vifor wind farm details
The Vifor wind farm will have 72 EnVentus V162 wind turbine generators (WTGs), each with a capacity of 6.4MW.
The turbines feature a three-bladed rotor with a diameter of 162m (531ft), and a rotor swept area of 20,612m². The turbines are installed atop 166m-tall hubs.
The 192MW phase one involved the installation of 30 WTGs. The 269MW second phase, which is under construction, includes the installation of an additional 42 wind turbines.
Vifor wind farm sub-projects
The wind farm’s development is segmented into five sub-projects, each defined by its geographical location.
The Costeşti wind farm, located within the Costeşti commune, consists of seven wind turbines with a total capacity of 44.8MW.
The Gheraseni wind farm in the Gheraseni commune also features seven turbines with a total capacity of 44.8MW.
The Smeeni commune hosts the Smeeni wind farm, equipped with 21 turbines and a combined capacity of 134.4MW.
The Luciu Wind Farm, in the Luciu commune, is home to 30 turbines, yielding a total of 192MW.
Lastly, the Ţinteşti sub-project includes seven turbines, resulting in a total capacity of 44.8MW.
Grid connection details
All WTGs across the project area are interconnected via underground cable lines to a single 260MV-ampere, 33/400kV transformer station.
The substation is located within the Pogoanele sub-project in Luciu commune, under the ownership of the Pogoanele Town Local Council.
Electricity generated from all sub-projects is conveyed to the collection substation via 33kV underground cable lines, which avoids the need to install intermediate transformer stations, thereby minimising the project’s environmental footprint.
The wind farm utilises a network of existing agricultural roads and newly constructed access roads. Underground cable lines will be installed along these roads.
The substation steps up the electric power generated by the wind turbines from 33kV to 400kV.
A 1.4km overhead transmission line with 400kV of capacity carries the electricity from the transformer to the National Energy System.
Power purchase agreement
In March 2026, Rezolv signed a ten-year virtual power purchase agreement with Etem Gestamp, a joint venture between Viohalco Group and Spain’s Gestamp Group, to sell electricity generated by the wind farm.
Project financing
Rezolv Energy and Low Carbon secured financing facilities amounting to $313m (€291m) in June 2024, including €32m from the European Bank for Reconstruction and Development (EBRD), to support the construction of phase one of the Vifor wind farm.
In July 2025, Rezolv Energy secured up to €331m in incremental project financing for the second phase, from a group of lenders comprising Erste Group Bank, UniCredit, EBRD, the International Finance Corporation and the Intesa Sanpaolo Group, along with OTP Bank and Raiffeisenlandesbank Niederösterreich-Wien. DNV acted as the lender’s technical advisor on the transaction.
Contractors involved
Vestas, a renewable wind energy and turbine manufacturing company, was responsible for developing the project’s first phase under a turnkey engineering, procurement and construction (EPC) contract. The scope of work included the supply of 30 wind turbines and delivery of operations and maintenance (O&M) services for the initial 15 years of operation. Rezolv will take over the operations after this period.
Vestas secured an order to deliver 42 turbines for the second phase in July 2025. The contract also includes a provision for O&M services for 15 years.
Direct Network Solutions, a technology and infrastructure company, carried out electrical testing and measurement works for turbines installed in phase one in collaboration with Vestas.
Electromontaj Group worked in partnership with Vestas to establish the connection facilities for the first phase of the project.
Polytrade Global, an EPC company, delivered the medium-voltage collector system for phase one.
Austrian infrastructure company PORR was chosen as the civil and electrical partner for the second phase of the project.
Ganz Transformers and Electric Rotating Machines, an electrical engineering company, was contracted to supply high-voltage grid transformers for the second phase.
IMSAT is responsible for the construction of the electrical infrastructure for phase two.
Tractebel, an engineering company, is serving as the owner’s engineer, while Concept Structure, a structural engineering company, designed the wind turbine foundations for the project.
Camissa, an independent advisory company, is providing design and implementation support for the post-construction bird and bat-monitoring programme.
CMS, a law firm, advised Rezolv Energy on the €331m financing secured in July 2025.
