N-Vision Energy has announced it will invest up to $210.5 million to build a 100 MW wind farm in Bulgaria.

The wind farm, which will be the second largest in Bulgaria (the largest is a 156 MW farm on the northern Black Sea coast), is going to be built about 42 miles south of Sofia. Operations are expected to begin in 2011.

And in solar news, the ENN Group has signed an agreement with Duke Energy to register a joint venture with the goal of becoming a PV systems provider in the U.S. The JV will focus on utility-scale solar farms and commercial distributed generation projects.

ENN operates China's first silicon thin-film photovoltaic module production line. The company's capacity has reached 70 megawatts, although expansion plans are expected to take capacity to 500 megawatts over the next two years.
