Poland: Nynas has recently reached an important milestone with GE Vernova by supplying almost 700 t of NYTRO® Lyra X transformer oil for the first phase of Poland’s largest offshore wind energy project.
The Baltica Offshore Wind Farm will be the biggest development of its kind in the Polish Baltic Sea and one of the largest offshore wind projects in the world. GE Vernova’s Grid Solutions is responsible for building the systems that connect power from the Baltica 2 project to the onshore electricity grid.
The first phase involved energising 80 offshore wind turbines, each rated at 15 MW, giving a total installed capacity of 1.2 GW. This marks the start of a long-term plan made up of eight stages, targeting 6 GW of offshore wind capacity and a total investment of $69 B (€60 B).
“The cooperation between Nynas and GE Vernova began in early 2024, when they decided to use NYTRO® Lyra X as insulating fluid in the transformers,” says Mateusz Kopecki, Sales Manager, Nynas Poland. “The first step was supporting them through the logistics and regulatory framework in Poland, particularly regarding excise duties during site fills.”
The transformers were produced in Turkey and shipped by sea before being transported offshore using specialised heavy-lift equipment. Four large transformers, each requiring 120 t of oil, and four smaller units, using 50 t each, were filled with a total of 680 t of Lyra X delivered by 28 Nynas trucks.
Filling work was carried out by Ecol using its Ecofluid system at a rate of 2 t per hour. The entire operation was completed within 45 days without delays.
Following completion, the Nynas team visited the site and received positive feedback from GE Vernova. Attention is now turning to phase two, planned for 2026, with an expected supply of 1,200 t of oil.
