Aquila European Renewables Income Fund has installed all 72 turbines at 400MW The Rock wind farm in Norway.
Construction is now complete and the project is entering a new phase where the turbines are being prepared for electricity production, Aquila said.
It said that most of the turbines are energised with the remaining machines to be fully energised by the end of December 2021.
Test runs will follow which are subject to site accessibility, depending on the weather, the fund added.
Commercial operation is expected in the first quarter of 2022.
It said a recent delay in commissioning from the fourth quarter of 2021 was largely driven by stronger than expected wind conditions, slowing down the installation works, as well as various effects from Covid-19 on the construction process.
Once in operation, the majority of the power from the wind park will go to the nearby Alcoa aluminium plant under a 15-year power purchase agreement (PPA).
The fund also announced that, following favourable pricing dynamics observed in Iberian power markets, it has negotiated additional PPAs for Benfica 3 solar project.
The new PPAs have a term of three years, with a pay as-produced structure. The additional PPAs increase Benfica III total P50 production coverage from 52% to approximately 85%.
The fund holds a 100% interest in Benfica 3, which was acquired in October 2020.
