The Metro Nashville District Energy System (DES) has provided heating and cooling to buildings in downtown Nashville for over four decades. In 2001, it was decided to replace the aging Waste-to-Energy Nashville Thermal Transfer Corporation (NTTC) facility (“Thermal”) with a new District Energy System in downtown Nashville. The new DES was implemented with several important objectives in mind:

  • To utilize state-of-the-art equipment with high reliability;
  • To keep costs as reasonable as possible and very predictable to the customers;
  • To be a visually attractive facility and environmentally friendly;
  • To be a long-lasting project that contributes positively to the economic stability and growth in downtown Nashville.

DESPlantIn November 2002, construction began on the new state-of-the-art facility and operation began in Mid-December 16, 2003. By January 2004 the plant was fully operational. The new DES facility provides steam and chilled water to heat and cool 42 downtown buildings and has received awards from the International District Energy Association for the most buildings signed up for service and second-most square footage signed up for service in 2003.

In April 2004, the Nashville Thermal Transfer Corporation formally turned over the 30-year-old Thermal Waste-to-Energy plant for complete demolition. The five-month project included the implosion of the large 200-foot concrete stack on July 26, 2004.
