Denmark’s Vestas, the world’s leading wind turbine supplier, is moving to acquire a stake in renewables project developer Sowitec — part of a trend of wind manufacturers diversifying to offer multi-technology solutions to customers around the world. Vestas this week announced a deal to acquire a 25.1 percent stake in privately owned Sowitec, with an option to buy the rest of the company within three years. Although based in Germany, Sowitec has made its biggest mark in Latin America, particularly Mexico and Brazil, and is active in both solar and wind development in more than a dozen countries.
