Sweden-based OX2 installed the last turbine at Nala Renewables’ Green Breeze wind farm in Romania as the contractor for its former project. Earlier it launched the construction of the Ansthall Green Energy facility of 96 MW for HELLENiQ Energy, under a similar arrangement. The company has also bought three wind power projects in Romania, totaling 235 MW.

OX2 Romania, a subsidiary of Swedish OX2, completed the last wind turbine at the Green Breeze facility of 99.2 MW. Construction started just over one year ago. The company sold the project last year to Nala Renewables, but stayed on as a contractor.

It was the first project in the country for OX2, which entered it four years ago. The facility is in Galați county in eastern Romania. The Sweden-based firm will also be tasked with operating the wind park, consisting of 16 Vestas V162-6.2 MW machines.

The forecasted annual output is 312 GWh. It is equivalent to the electricity consumption of 51,000 Romanian households.

Nala Renewables claimed that Green Breeze would lower carbon dioxide emissions by 150,000 tons per year, per the United Nations Climate Change IFI Default Grid Factors. IFI stands for international financial institutions.

Apple recently expressed interest in buying electricity from Green Breeze under a long-term virtual power purchase agreement or vPPA.

Project pipeline in Romania expands by 235 MW

Earlier this month, OX2 said it acquired three wind power projects in Romania totalling 235 MW from Future Power. The sites are in Vaslui and Vrancea counties. OX2 boosted its portfolio in the country to more than 1.1 GW with the transaction.

It expects to commission the three facilities between 2028 and 2030, subject to permitting. OX2 also continues to develop additional wind projects in regions with strong wind resources including Constanța, Brăila and Galați.

The company has nine onshore wind projects under­ construction in Romania, 195 MW overall, and 766 MW in development, as well as 150 MW in solar and battery storage projects.

OX2 breaks ground for Ansthall wind farm after selling it to HELLENiQ Energy in August

Within an arrangement similar to the one with Nala Renewables, OX2 started building the Ansthall Green Energy wind farm of 96 MW in November. It is located in Galaţi, in the communes Scânteiesti, Fârţăneşti, Cuca, Schela, Cuza-Vodă, Pechea, Rediu and Slobozia-Conachi.

The wind farm is set to feature 15 Vestas V162 turbines of 6.4 MW, the largest in Romania so far. Rezolv Energy is installing the same kind in its giant project Vifor in Buzău.

HELLENiQ Renewables Romania, operating under HELLENiQ Energy, acquired the project from OX2 in August. The Greek company expects to put the facility into operation in 2027.

Total annual output is estimated at 309 GWh, equivalent to the electricity needs of 89,000 domestic households.

Earlier, OX2 signed a 12-year virtual power purchase agreement (PPA) with Koninklijke Ahold Delhaize, for 158 GWh per year. The future offtaker operates supermarket chains.

Headquartered in Stockholm, OX2 is owned by EQT, one of the world’s largest private equity firms.
