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 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 Contractor, that under an EPC contract arrangement will execute full scope of onshore grid connection assets of Baltic Power Offshore Windfarm.
The subject matter of the contractor's works under the EPC contract is expected as follows:
- Construction of all components including overhead lines to SE Choczewo Substation in accordance with Polish construction laws.
- Delivery, installation, and commissioning of all equipment required
- Detailed design and technical analyses required to complete contract
- Performance of all other works relating to the connection of the Offshore Wind Farm to the National Power System (NPS) ensuring compliance with the issued Grid Connection Conditions (GCC)
