The biggest addition of the year is the 156 MW St Nikolas wind farm, near the municipality of Kavarna on Bulgaria's Black Sea coast. AES Geo Energy, the majority-owned subsidiary of American utility AES, has completed construction work on the EUR270 million project - Bulgaria's largest wind farm to date - and expects it to be connected to the grid in the next few months. It comprises 53 Vestas 3 MW turbines. Bulgarian-German firm Geo Power is the minority shareholder in AES Geo Energy. Meanwhile, Italian utility Enel has recently commissioned its 21 MW Kamen Briag wind farm in Kavarna, while another 21 MW in Shabla, also on the Black Sea coast, is due online by the end of the year. Both projects were acquired late last year from Global Wind Power Bulgaria, a subsidiary of Danish firm Global Wind Power, and both also use 3 MW Vestas machines.
