Nissan plant cuts energy costs by 3M kilowatt-hours annually

The Nissan Powertrain Assembly Plant in Decherd is now running a more energy-efficient machining facility thanks to a joint effort by the Duck River Electric Membership Corporation (DREMC) and TVA.

TVA’s Major Industrial Program, in partnership with DREMC, reimbursed 70 percent of the $296,000 project cost to reduce the electricity consumed at the Decherd plant annually by three million kilowatt-hours.

This was accomplished by installing new variable-speed motors on each of the plant’s 43 mist collectors, which had been “regular one-speed” motors since installed and required “quite a bit of energy” to run at a constant speed regardless of how much air was being pulled through, according to Senior Environmental Engineer Tracy Brooks.
