Bulgaria's Ecosource Energy is investing over BGN 156 million (EUR 79.7 million) in the construction of Bulgaria's first wind farm on the ridge of Stara Planina in the region of Murgash Peak. The 100 MW project will consist of 44 Enercon 2.3 MW turbines installed at a height of 1500-1600 metres. According to Vladimir Nikolov of Ecosource Energy, the first 20-turbine stage of the project will be completed by the end of the year, with the remaining 24 generators installed over the next two years. Preliminary data indicates the first phase will operate for a minimum 3000 hours a year at full load equivalent, producing 180,000 MWh, he says. Ecosource will also build an 110 kV power line. Ecosource Energy was last month certified as a First Class investor by the Invest Bulgaria Agency, entitling the company to government assistance for the construction of the necessary infrastructure. Ecosource Energy, which expects to recoup the investment in nine years, will provide 30-50% of the project financing, with the remainder coming from bank loans. Bulgaria's national power grid operator NETC will purchase the wind farm's output at BGN 0.12/kWh (EUR 0.06/kWh).
