Equinor and Polenergia have applied for environmental approval for the grid connection infrastructure for the Bałtyk I offshore wind farm in Poland.
The project, which is being prepared for auction in 2025, is the largest and most advanced offshore wind farm in the Baltic Sea.
The 1560MW Bałtyk I follows the partner’s earlier projects, Bałtyk II and Bałtyk III. Due online in 2027, these two will have a combined capacity of 1440MW, with turbines supplied by Siemens Gamesa Renewable Energy.
“A common corridor section for the cable bringing power out of all three Bałtyk projects will significantly shorten the investment process, make it easier and cheaper,” said Jerzy Zań, chief executive officer of Polenergia.
Bałtyk I is located about 80km from the coast and is planned to come online in 2030. Electricity from the project will flow via cables to a connection point at the Polish Power Grid Krzemienica substation, currently under construction in the Redzikowo municipality. A land connection infrastructure corridor of up to 20km will run underground to preserve tourism and scenic values and to minimise impacts on existing land use.
The planned onshore power exit will be implemented partially in the immediate vicinity of the corridor designated for the connection infrastructure of the Bałtyk II and Bałtyk III offshore wind farms. One landfall location using trenchless technology is planned for all three wind farms.
To date, Bałtyk I has obtained a permit to lay and maintain cables in the offshore section and a grid connection agreement with the transmission system operator. An application has also been made to the Polish Power Grid to change the connection conditions for Baltic I to high voltage direct current technology.
