Oak Ridge has been chosen for a $2.9 million TVA grant that will help residents save money on their utility bills, while making some of the city’s so-called legacy housing more energy efficient. Legacy homes are those homes in Oak Ridge that date back to the Manhattan Project and the Cold War era. TVA’s Extreme Energy Makeover Project allows communities like Oak Ridge to renovate those homes to make them more energy-efficient. The project will include a partnership between the city’s electric department, TVA, Aid to Distressed families of Appalachian Counties (ADFAC), Gilmartin Engineering Works, Tetra tech and Strata-G. The grant funds will be used to perform whole-home, deep energy retrofit upgrades to achieve a 25 percent reduction in electric energy usage. The project will get started in April 2016 and run through September of 2017.
