Onshore part of grid connection assets of the Baltic Power offshore windfarm, that include onshore cable lines, onshore substation and overhead lines connecting Baltic Power substation with National Grid will be constructed in the Choczewo commune in Northern Poland.
The 6.5 km onshore cable route will be routed via underground single-core AC cables with an operating voltage of 220 kV or 275 kV. The onshore cable route starts at the Transition Joint Bays located near the shore, through forest area and terminates at the Baltic Power high voltage onshore substation, from which power will be transferred to National Grid via 400 kV overhead lines. The onshore substation will be equipped among others with reactive power and voltage control equipment to ensure compliance with Polish Grid-Code requirements. The Baltic Power project is planning to select a Contractor, that under an EPC contract arrangement will execute the full scope of onshore grid connection assets of Baltic Power Offshore Windfarm.
