Largest wind farm in the Baltic prepares for auction

Equinor and Polenergia have applied for an environmental decision for the connection infrastructure of the Bałtyk I offshore wind farm, which is being prepared to participate in the 2025 auction.

Bałtyk I is the project of the largest wind farm in the Baltic Sea and at the same time the most advanced project of the so-called second phase of offshore wind energy development in Poland.

“In the implementation of the Bałtyk I wind farm, we will use the best solutions developed in the construction of the previous projects, Bałtyk II and Bałtyk III. This will significantly streamline the investment process,” both companies emphasise.

The Bałtyk I offshore wind farm is one of three projects jointly developed by Equinor and Polenergia. Bałtyk I, Bałtyk II and Bałtyk III will have a total capacity of up to 3 GW, allowing more than 4 million households to be supplied with green energy. Bałtyk I is the largest wind farm project currently under construction in the Baltic Sea, with a capacity of up to 1560 MW.

The Baltic I offshore wind farm will be located approximately 80 km from the coastline. Electricity from the project will flow via cables onshore to a connection point at the Polish Power Grid Krzemienica substation under construction in the Redzikowo municipality. The onshore connection infrastructure corridor of up to 20 km in length will run underground to preserve the tourist and landscape values and to minimise the impact on existing land use.

The planned onshore power derivation will be implemented partly (in the northern part of the run) in the immediate vicinity of the corridor designated for the connection infrastructure of the offshore wind farms Bałtyk II and Bałtyk III. One landfall location using trenchless technology is envisaged for all three wind farms.

To date, Baltic I has been granted permission to lay and maintain cables in the offshore section and a grid connection agreement with the transmission system operator.

– We are actively participating in the country’s energy transition by developing offshore wind energy so that Poland can benefit from energy produced from renewable sources. We have the highest quality technologies and solutions that we implement in our projects. Bałtyk II and III will be among the first offshore wind farms in the Polish sea and are scheduled to be operational in 2027. Baltic I is the most advanced phase two project, scheduled for auction in 2025. The green energy that will flow from all three offshore wind farms will provide stable renewable energy for more than 4 million households, says Michał Jerzy Kołodziejczyk, CEO of Equinor in Poland.

As part of the project, the collection of offshore measurement and meteorological data during more than a year-long study of wind and wave intensity has been completed. This will allow the expected energy production of the wind farm to be determined. In addition, last year’s seabed survey provided a preliminary understanding of the geological conditions of the site, relevant to the design process. This is essential research that will be used to create the most production- and cost-efficient siting of the individual turbines.
