Cumberland Fossil Plant Retirement

Stewart County, Tennessee

In June 2019, the Tennessee Valley Authority (TVA) published the 2019 Integrated Resource Plan (IRP), a comprehensive study of how TVA can best meet the future energy demand in its power service area, which encompasses approximately 80,000 square miles covering most of Tennessee and parts of Alabama, Georgia, Kentucky, Mississippi, North Carolina, and Virginia. Following the publication and recommendation of the 2019 IRP, TVA began conducting end-of-life evaluations of our coal fleet to inform long-term planning.  The results of the Aging Coal Fleet Evaluation confirmed that TVA’s coal fleet is among the oldest in the nation and is experiencing material condition and performance challenges typical for plants approaching the end of their useful lives, and concluded that a phased plan to retire TVA’s coal fleet by approximately 2035 is aligned with least-cost planning and reduces economic, reliability and environmental risks. The evaluation also recommended specific planning assumption retirement dates for each of the coal plants to facilitate the 2035 end-of-life timeline.

Consistent with the 2019 IRP and the Aging Coal Fleet Evaluation, TVA prepared an Environmental Impact Statement (EIS) to assess the Proposed Action of retiring and decommissioning the two coal-fired units at Cumberland Fossil Plant (CUF) (one unit by 2026 and the second unit by 2028) and implement replacement generation that can supply 1,450 MW of firm, dispatchable power by the time the first unit is retired in 2026. The need for the Proposed Action is to ensure that TVA can meet required year-round generation and maximum capacity system demands and planning reserve margin targets, particularly during peak load events.

TVA considered three action alternatives in the EIS: (A) Retirement of CUF and construction and operation of a Combined Cycle Combustion Turbine Gas Plant at the same site; (B) Retirement of CUF and construction and operation of Simple Cycle Combustion Turbine Gas Plants at alternate locations; (C) Retirement of CUF and construction and operation of Solar and Storage Facilities, primarily at alternate locations. TVA’s preferred alternative is Alternative A.

TVA anticipates making a decision in January 2023.

Public Involvement

TVA conducted scoping on this project and requested public comments on the scope of the EIS, alternatives being considered, and environmental issues that should be addressed as a part of this EIS. The public scoping period ran from May 11, 2021, to June 10, 2021. Comments were received by mail, email, and electronic comment forms. A copy of the comments received can be found in the scoping report linked in the “Related Documents” section below.

The Draft EIS (DEIS) was made available for public review on April 29, 2022, and the public comment period ran through June 13, 2022. TVA received 770 comments and 930 signatures on the DEIS. TVA carefully reviewed all of the substantive comments that it received. To avoid repetition, TVA grouped similar comments and produced one synthesized response for each comment grouping that resulted in responses to approximately 116 comment groupings. TVA’s responses to the comments can be found in Appendix O of the Final EIS.
