Canadian power producer Northland Power and Poland's biggest energy company Orlen have completed the installation of all 76 turbines at Poland's first offshore wind project, Baltic Power, they said on Wednesday.
The 1.1 gigawatt facility, jointly owned by Northland and Orlen, is on track to begin commercial operations in 2026, the companies said.
Overall costs are aligned with original expectations as the project advances through commissioning, Northland said.
More than one-third of the turbines are already generating power, following the delivery of the project's first electricity to the grid in July.
The facility will generate around four terawatt-hours of electricity per year.
It is undergoing tests to provide enough electricity to power more than 1.5 million Polish households in a few months.
The project is underpinned by a 25-year contract-for-difference subsidy mechanism that will provide revenue certainty for the developer, with the costs ultimately borne by taxpayers.
