General Electric (GE) has expanded its investments to include manufacturers of renewable energy industry components. They've just made an investment in TPI Composites, a former fiberglass boat manufacturer, now a manufacturer of fiberglass parts for the wind energy and other industries. TPI Composites raised $20 million in round A funding from Landmark Growth Capital Partners, NGP Energy Technology Partners, and Angeleno Group, and GE.
The company's portfolio of products include composite materials for wind turbines, military vehicles, and various other transport applications. Fiberglass technology provides strong but light materials, which improve performance and reduce production costs. According to this article on CNET News, the company currently supplies wind turbine blades for GE and Mitsubishi Power Systems.
