SPIE’s new substation in Choczewo, Poland will help connect valuable renewable energy resources to the national grid.
Traditionally, Poland has relied on coal for most of its electricity production, but photovoltaics (PV) and offshore wind are both on a rapid rise. PV counts 23.6 GW of capacity as of August 2025, and the government is targeting an offshore wind capacity from Baltic Sea wind farms of up to 11 GW by 2040. As renewable energy production in Poland continues to ramp up, new projects must safely and reliably connect to the grid.
The 400 kV Choczewo substation is helping to meet this need. It is the first and largest of its kind in Poland, equipped with cutting-edge technology that helps stabilise the grid. As SPIE continues to build substations around the country, it plans to be heavily involved in the next development phase: energy storage installations.
