Polish company PKN Orlen and Canadian outfit Northland Power have opened a tender to the onshore grid infrastructure to link the 1200MW Baltic Power offshore wind farm off Poland to the grid.
The 6.5km onshore cable will be routed via underground single-core AC cables with an operating voltage of 220 kV or 275 kV.
It will start at the transition joint bays located near shore, through a 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 with reactive power and voltage control equipment to ensure compliance with Polish Grid-Code requirements.
The developers are planning to select a contractor under an EPC contract arrangement to execute the full scope of onshore grid connection assets.
Works cover construction of all components including overhead lines to SE Choczewo substation in accordance with Polish construction laws, and delivery, installation and commissioning of all equipment required, as well as design and technical analysis.
Interested parties have until 14 September to express an interest in bidding.
Final decisions on the successful bidder will be made next year, with preferred bidder selected completed by 1 August 2022.
