An environmental decision has appeared for the 400 kV Choczewo – Zarnowiec line, which was made by the Regional Director of Environmental Protection in Gdansk. Officials have issued an environmental decision for the construction of the project. The decision was announced on social media by Anna Trzeciakowska, Government Plenipotentiary for Strategic Energy Infrastructure.
Construction of the 400 kV Choczewo Zarnowiec line is expected to begin next year and be completed in 2025. This is one of the most important elements of the development of the transmission system in Poland related to the construction of offshore wind farms.
At the end of last year, Polish power grid operator (PSE) presented a plan for the development of the transmission system until 2032. Offshore wind energy is one of the key areas of system transformation. This is followed by investments in infrastructure to take power out of the Baltic Sea and transmit it to southern Poland.
Development plan for meeting current and future electricity demand for 2023-2032 [„Plan rozwoju w zakresie zaspokojenia obecnego i przyszlego zapotrzebowania na energie elektryczna”] has been agreed with the ERO president. The document indicates that the main investments that PSE is planning are to support, among other things, the government’s plan to build offshore wind farms in the Baltic Sea. – declared by, then president of PSE, Eryk Klossowski
The total production potential of the various types of RES indicated by PSE implies the possibility of producing more than 100 TWh per year of renewable energy by 2030, which will significantly exceed 50% of Poland’s net electricity demand given current projections and is significantly more than the levels assumed in national strategic documents.
The Polish Power Grid indicates that so far (as of the end of 2021) 8.389 GW of offshore wind farms have been contracted for connection to the transmission grid. And based on the value specified in the offshore wind power support law, 10.9 GW of offshore wind power is expected to be built in the NPS over the next 10 years, with a production potential of 40 TWh.
The following capacities of offshore wind power plants in 2032 were assumed: Krzemienica Station (Slupsk Station area) – 4.422 GW, Choczewo Station – 5.039 GW and Slupsk Station – 1.440 GW.
The document included a detailed list of ongoing and planned investments in the expansion and modernization of the transmission network to derive power from offshore wind farms and transmit electricity in the north-south direction.
