A new Tennessee Valley Authority rate hike took effect starting June 1st but MTEMC customers in Rutherford and Cannon Counties should only see a slight increase. Customers will see the slight increase on the Fuel Cost Adjustment line item on their June bills. According to Middle Tennessee Electric Membership Corporation Communications Coordinator Todd Palmer, because of damage to the Brown’s Ferry Nuclear Plant, caused by the spring storms this year, power production capablities has been interrupted and that in turn forced TVA to purchase more expensive power to meet demand.The Fuel Cost Adjustment is affected monthly by the fluctuating global costs and demand of coal, natural gas, nuclear fuel and other fuels used by the Tennessee Valley Authority to produce electricity. Palmer also reminds customers that the hottest months of the year are upon us and as a result, consumers will be using more energy. He encourages everyone to participate in the online home energy evaluation on their website mtemc.com
