A new solar field capable of supplying 12 percent of Volkswagen’s Chattanooga assembly plant is now online. With a generating capacity of 9.6 megawatts of direct current, the 33-acre solar field is the largest one at any industrial plant in the world, the largest in Tennessee, and the largest at any automaker, Volkswagen says.
The Tennessee plant builds the Volkswagen Passat mid-size sedan. In 2011, it became the first automotive assembly plant in the world to receive the LEED Platinum Certification from the U.S. Green Buildings Council, the highest such certification.
The U.S. Environmental Protection Agency has ranked the VW factory as the 11th best on its top 20 list of on-site buyers of green energy. The total energy production is 13.1 gigawatt-hours each year approximately the energy used to power 1,200 homes.
