Mitsubishi/TPI Wind Blade Factory Triples Capacity in Mexico


Warren, Rhode Island - April 3, 2007 - VienTek LLC (VienTek), a joint venture between Mitsubishi Power Systems Americas, Inc. (MPS) and TPI Composites, Inc. (TPI), has launched plans to triple the capacity of their wind blade manufacturing operation in Juarez, Mexico from 400MW to 1200MW per year.

When this expansion is complete in October 2007, VienTek will have two plants on one campus with a total of 500,592 square feet of manufacturing space and 800 employees. VienTek has taken control of the complete 45 acre land site which provides space for even further expansion.

VienTek manufactures blades using TPI's patented SCRIMP® process technology, a highly advanced form of vacuum infusion. VienTek also manages a 15 acre blade storage facility in Santa Teresa, New Mexico.
