The 15.4-MW Podlasek and the 34.5-MW Wolka Dobrynska were secured in the country's third energy auction. Greenvolt expects the parks to begin power generation by end-2022.

Danish wind turbine maker Vestas was selected as the turbine supplier. The company will maintain the equipment for a period of 30 years, Greenvolt said in the press release.
