Croatia’s Trtar-Krtolin wind farm is preparing a repowering project that would raise installed capacity from 11.2 MW to 30 MW and add battery storage. Located near Sibenik, the wind farm has operated since 2006 and was Croatia’s second wind farm.
The project would replace 14 Enercon E-48 turbines, each rated at 800 kW, with five turbines rated at 6 MW each. It also includes four battery units with combined storage capacity of 10 MW/20 MWh. The storage is intended to improve the plant’s ability to manage intermittent generation and participate more flexibly in the electricity market.
Reconstruction is expected to take place in stages, covering new turbine foundations, electrical connections and communications infrastructure. The project is being developed by Vjetroelektrana Trtar-Krtolin, a subsidiary of German renewable energy developer wpd. Once completed, it would almost triple the site’s installed generating capacity while continuing to use much of its established grid and energy infrastructure.
