Energy savings at the Y-12 facility in Oak Ridge were lauded by the Tennessee Chamber of Commerce and Industry, according to a news release.
The Chamber recognized the Y-12 National Security Complex with one of its Environment & Energy Awards, winning the Comprehensive Energy Excellence Award for seeking out energy savings performance contracts and energy improvement projects.
The facility won recognition in the category for employers with more than 250 employees.
“Each year we have a number of great applications that we receive from companies all across our great state who are committed to energy conservation practices,” Bradley Jackson, president and CEO Tennessee chamber, wrote in an email. “Specifically, Y-12 National Security Complex stood out based on their outstanding achievement toward proactive and innovative energy policies that reduce energy consumption and water use. “
Specifically, three efficiency projects were recognized.
“It is an honor to represent Y‑12 and receive awards on behalf of the employees who work to make the recognition possible,” Y-12’s Environmental Compliance Manager Stacey Loveless said in a release. “We are happy to share with others the green news we have at Y‑12.”
One project was a steam decentralization project that took 21 buildings off the plant’s steam distribution system, which also removed more than 3,000 feet of leaking lines. Those lines were replaced with natural gas lines. A news release said the project is expected to save nearly 1.8 million kWh of electricity, 170,000 MBtu of natural gas, 36 million gallons of water and more than $800,000 annually.
The second project was installing high-efficiency cooling towers and upgrades to the chiller system. That eliminated systems using R-22 refrigerant, supported infrastructure renewal and eliminated a significant amount of deferred maintenance, the release read, which led to saving 16 million kWh of electricity and $1.7 million annually.
The third project replaced or upgraded 37,800 lighting fixtures across Y-12. Fixtures were replaced with a combination of LED, long-life T-8, compact fluorescent lamps and other similar efficient lighting systems. Ballasts containing with PCBs were replaced with solid-state ballasts. That project is expected to save more than 22 million kWh of electricity and almost $2.7 million annually.
“Our operations personnel continually look for changes they can implement to improve efficiency, and Y-12’s programs and employees reach beyond the obvious when looking for ways we can improve the environment,” Loveless said in the release.
