The first electricity from Poland’s offshore wind sector flowed into the grid through the Choczewo substation.

A turning point in the history of Poland’s energy sector

In July 2026, the newly built PSE Choczewo power substation in Pomerania officially received the first power from the Baltic Power offshore wind farm. This marked the moment when clean energy from the Baltic Sea flowed into the National Power System for the first time. The ceremonial launch of this strategic infrastructure in Choczewo (Osieki Lęborskie) was attended by, among others, Prime Minister Donald Tusk, Minister of Energy Miłosz Motyka, Minister of Finance and Economy Andrzej Domański, and Canada’s Minister of Energy and Natural Resources Tim Hodgson.

The largest energy gateway in Poland

The Choczewo power substation is currently the largest and most technologically advanced facility of its kind in the country. It is this infrastructure that ensures the safe reception of offshore energy and transforms it so that it can be transmitted deep into Poland.

Scale of the investment in numbers:

• 25 hectares — total area of the substation.
• 40 bays at 400 kV equipped with nearly 800 high‑voltage devices.
• 9,500 tons of foundations and more than 800 tons of steel structures.
• 300 kilometers of installed cables and 8 kilometers of internal roads.

Construction began in 2019, with the most important works carried out by Pomeranian companies SPIE Energy Poland and Elfeko. Equipment for the substation was supplied by leading market players such as Hitachi Energy Poland, Siemens Polska, Tele‑Fonika Kable, Arteche, and Olmex from Olsztyn. Notably, Polish companies delivered supplies and works worth more than 140 million PLN, of which 60 million PLN went to local entities from Pomerania.

The investment was financed 100% from the National Recovery Plan (KPO) — the funding for the substation itself amounted to approximately 530 million PLN. The export power lines also received KPO support.

Baltic Power inaugurates the era of Polish offshore wind

The first megawatt‑hours transmitted to the Choczewo substation were produced by the Baltic Power offshore wind farm — a joint project of ORLEN Group and Canadian company Northland Power.

The installation, with a target capacity of approx. 1.2 GW, will generate around 4 TWh of electricity annually once fully operational. This volume is enough to meet the demand of more than 1.5 million Polish households, corresponding to about 3% of total national electricity consumption.

A target of 6 GW of capacity

The launch of Baltic Power is only the beginning of a major plan by Polskie Sieci Elektroenergetyczne (PSE) for northern Poland. The Choczewo substation has been designed to ultimately receive power from six offshore wind farms.

The next projects to be connected to the substation in the coming years will be:

• Baltica 2 (developed by PGE) — planned start in 2027.
• BC‑Wind (developed by Ocean Winds) — planned start in 2028.

The total installed offshore capacity connected to Choczewo will exceed 6 GW — more than the capacity of Poland’s largest conventional power plant, Bełchatów. Due to the enormous energy potential of this node, PSE is already seeing strong interest from investors planning to build large data centers and utility‑scale energy‑storage systems in the region.

Polish‑Canadian partnership and plans through 2040

The event in Pomerania also served as a platform to strengthen strategic cooperation between Poland and Canada. Ministers Miłosz Motyka and Tim Hodgson discussed joint steps in offshore wind energy, nuclear energy development, LNG technologies, and energy‑storage systems.

According to Poland’s energy policy, offshore wind is set to become one of the pillars of the modern energy mix. The national plan assumes achieving approx. 5.9 GW of installed capacity in the Baltic Sea by 2030, with dynamic growth to up to 18 GW by 2040.
