The Tennessee Valley Authority announced plans to retire 18 older coal-fired generation units at three power plants as part of the federal utility’s vision of being one of the nation’s leading providers of low-cost and cleaner energy by 2020. The retirements, which include about 1,000 MW of coal-fired capacity previously slated for idling, mean TVA will have idled or retired about 2,700 MW of its 17,000 MW of coal-fired capacity by the end of 2017.
The coal-unit retirements announced include two at John Sevier Fossil Plant in East Tennessee, six at Widows Creek Fossil Plant in northern Alabama and all 10 units at Johnsonville Fossil Plant in Middle Tennessee. TVA announced in 2010 that it would idle units at John Sevier and Widows Creek, as well as one of 10 units at Shawnee Fossil Plant near Paducah (Kentucky).
TVA estimates that it will invest an additional $3 billion to $5 billion in the next 10 years on new emission-control equipment and upgrades of existing equipment at its coal plants.
