• Initial contacts with the major technology suppliers (Siemens,
ABB) concerning offshore wind farms and sea grids.
• Analysis of the first location concept of the offshore wind farm
connection at sea (SwePol II construction with offshore wind farm
connection).
• Analysis and developing of HV DC offshore wind farms
connection concept to the National Grid with omitting the
Transmission Grid at the north part of Poland.

The first offshore wind farm connection concept
The initial analysis indicates that in case of the possible construction of the second
(parallel to the existing) SwePoll II link to Sweden, it would be feasible to install on it
the first offshore wind farm connection. In such configuration the power from the
offshore farm could be directed to the Polish National Grid and / or to the export.
According to PSM the construction

According to PSM the construction
of SwePol II and the first offshore connec-
tion would be much easier due to the loca-
tion of the new line as parallel to the exis-
ting SwePol I.
The location concept of the first offshore
connection on the existing SwePol I line,
which is possible, is not considered.
