Phase 1 of Rezolv's VIFOR wind farm in Buzău County, Romania, has entered its trial period, marking a significant step toward full commercial operation for a project that will ultimately deliver 461 MW of generating capacity to the country's energy mix.

Thirty Turbines Begin Trial Operations

Rezolv confirmed that Phase 1 of the VIFOR wind farm, comprising 30 high-capacity turbines with a combined capacity of 192MW, is now undergoing its trial period.

The company described the milestone as bringing the project one step closer to full operation. The trial period represents a critical phase in any wind farm's development, during which turbines are tested and assessed before the site transitions to commercial generation.

The VIFOR project is located in Buzău County in eastern Romania, a region that has emerged as a significant hub for renewable energy development in the country.

The scale of the Phase 1 installation, with 30 turbines already spinning, reflects the ambition behind a development that Rezolv has been advancing through multiple financing and commercial agreements over the past two years.

Phase 2 Already Under Construction

Even as Phase 1 moves through its trial period, Rezolv has already begun work on Phase 2 of the project. The company confirmed that Phase 2 is currently under construction and will bring VIFOR to its full capacity of 461 MW.

Phase 2 is scheduled to be commissioned in summer 2027, meaning the complete project could be operational within roughly a year of Phase 1 completing its trial process.

The expansion from the 192MW Phase 1 to the full 461MW capacity represents a significant scaling of the project, with Phase 2 adding substantially more generating capacity than the first phase alone.

The timeline, with Phase 2 targeting a summer 2027 commissioning, reflects an aggressive construction schedule being maintained in parallel with Phase 1's final steps toward operation.

Background: Financing and Offtake Agreements in Place

The trial period announcement comes after a series of commercial and financial milestones that have underpinned the project's development. In July 2025, Rezolv secured USD 386.7 million in financing for the Vifor project, providing the capital base necessary to fund construction across both phases.

That financing agreement was followed in August 2025 by Rezolv securing 731 MW of capacity in a Romanian contract-for-difference auction, a result that demonstrated the company's broader ambitions in the Romanian renewable energy market beyond VIFOR alone.

Earlier, in September 2024, Rezolv and APA inked a wind energy offtake agreement for Romania, establishing a commercial framework for the energy the project will generate.

Together, these agreements, covering financing, revenue certainty through the contract for difference mechanism, and offtake arrangements, reflect the layered commercial structure that Rezolv has assembled to support VIFOR's development from construction through to long-term operation.

Romania's Growing Role in European Wind Energy

The VIFOR project sits within a broader context of renewable energy expansion across Central and Eastern Europe, where countries including Romania have been accelerating the development of onshore wind capacity to meet both national energy targets and European Union climate commitments.

Romania's geography, particularly in regions such as Buzău County, offers strong wind resources that have attracted investment from developers seeking to build utility-scale projects.

For Rezolv, VIFOR represents one of the most significant individual projects in its portfolio, both in terms of its ultimate 461MW capacity and the scale of investment it has attracted.

The combination of a contract for difference secured through a competitive auction, project financing exceeding 300 million euros, and a signed offtake agreement provides a relatively comprehensive commercial stack for a project of this type.

Next Steps Toward Full Operation

With Phase 1's 30 turbines now in their trial period, the immediate focus for Rezolv will be completing the testing and commissioning process for the 192MW first phase while simultaneously progressing Phase 2 construction toward its targeted summer 2027 commissioning date. The parallel tracks of finalising Phase 1 and building Phase 2 will require sustained operational and logistical coordination across the Buzău County site.

Once Phase 2 is commissioned and VIFOR reaches its full 461 MW capacity, it will stand as one of the larger onshore wind installations in Romania and a flagship asset in Rezolv's Central and Eastern European renewable energy portfolio.
