In May 2026, the 400 kV Choczewo substation, built by a consortium led by SPIE Energy Poland, began supplying power for the Baltic Power customer substation’s own needs. This enabled the commissioning of infrastructure for receiving energy from offshore wind farms and integrating it into the national electricity system.
This marks another significant milestone in the project, confirming the substation’s readiness to support the transmission of renewable energy from the Baltic Sea to consumers across Poland. The Choczewo substation is the country’s first power hub designed specifically for offshore wind energy and is a key element of Poland’s energy transition.
The Choczewo substation project is an example of an investment that combines technical innovation, strategic importance for energy security and a tangible socio-economic impact. It has been designed with a view to future expansion and the integration of new technologies. Plans include connecting an energy storage facility and a data centre, which will increase the flexibility of the electricity system, improve grid stability as the share of renewable energy sources grows, and support the development of the digital economy.
– Leszek Goli, CEO of SPIE Energy Poland
The project is being carried out on behalf of Polskie Sieci Elektroenergetyczne by a consortium comprising SPIE Energy Poland and Elfeko. Advanced commissioning work is currently underway at the site, and the entire project is scheduled for completion in 2027.
