How wind power grew in Bulgaria
The Kaliakra wind farm, on a cape on the Black Sea coast, was running by August 2008. Mitsubishi Heavy Industries owned 70% of it and the Bulgarian engineering firm inos 30%. Its 35 Mitsubishi turbines of 1 MW sold all their output to the state utility NEK. In October 2009 AES connected the 156 MW Saint Nikola farm near Kavarna, at a cost of €270m. Bulgaria then had 330 MW of wind.
In September 2012 the energy regulator imposed a grid-access fee on all renewable producers, without consultation and with retroactive effect. For wind it was 10% of the feed-in tariff. Ember describes wind generation as essentially stalled since 2012, citing weak governance, a lack of political will and limited grid access. In February 2026 WindEurope said Bulgaria had not installed a single turbine in more than a decade. Vestas, present since 2007, has more than 360 MW in the country.
IRENA counted 706 MW at the end of 2025, virtually unchanged since 2014. Wind generated 1.32 TWh in 2025, 3.5% of generation. New building is due to resume in 2027, when the 70 MW Strazhitsa farm near Balchik is to be commissioned with eleven Vestas turbines. A draft update of the national energy and climate plan, put to consultation in July 2026, plans 1,280 MW of new onshore wind and the first Black Sea offshore farms.
