Alabama

Middle Tennessee Generation and Transmission Capacity Expansion Project (Cheatham and Robertson Counties)

Update – April 2024

TVA has identified the preferred location for a power line that would provide power for growing load and increase power reliability in the Cheatham County area of Middle Tennessee.

TVA evaluated each route using social, engineering, and environmental factors.  Information sources included available data, aerial photography, limited onsite reviews, public review and comment, and property owner input.  Based on public input and evaluation, the preferred route is expected to have the least overall project impact of the alternatives.

TVA’s proposed 3.08-mile line would begin at TVA’s existing West Nashville-Clarksville 161-kilovolt Transmission Line, north of Sweethome Road, and would end at TVA’s Cheatham County Substation located at the proposed Cheatham County Natural Gas Generation Facility on Lockertsville Road.

The route selected is Route No. 1 consisting of Loop Point No. 1 and Segment Nos. 33 and 37 as presented at the open house in Ashland City March 6 and 7, 2024, and online at the virtual open house from March 6 through April 8, 2024.

The new line will be built using primarily double-pole (H-frame), steel structures with potential for steel towers in mountainous areas.  Structures would be centered on new, 100-foot-wide right of way.  There is potential for an additional 87.5-foot width when Phase 2 routes are announced in areas where parallel options were presented.

Surveys of the right of way are scheduled to begin in winter 2024-2025.

The line is scheduled to be in service no earlier than 2028.

The National Environmental Policy Act review is pending.

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Cheatham and Robertson County areas of Middle Tennessee.

The planned retirement of TVA’s Cumberland Fossil Plant creates the need to add new generation to the TVA system at a location that will provide reliable electric power to the Middle Tennessee area for decades to come.  Leveraging of the existing 161-kilovolt transmission infrastructure in the area, increasing Middle Tennessee electrical power demand, existing TVA-owned property, and maintaining system stability by providing grid support are criteria that make Cheatham County an ideal location for a proposed new, gas-powered generation plant.

The Middle Tennessee area can experience an issue known as fault-induced delayed voltage recovery (FIDVR) when certain 500-kilovolt transmission lines are removed from service by a storm, planned maintenance outage, or some other event.  When FIDVR occurs, it can lead to area instability and potential blackouts.  New generation on the 161-kilovolt system (e.g., proposed Cheatham County Gas Plant) would reduce the likelihood and severity of FIDVR events.

Inverter-based resources (IBRs), such as solar generation and battery storage, do not support the stability of the transmission system like traditional spinning generation.  IBRs are also typically located farther away from densely populated areas due to geography and land availability.  As more legacy fossil plants (i.e., spinning generation) are retired and more IBRs are added to the system, replacement generation moves away from load centers.  As a result, stability concerns such as those seen in Middle Tennessee worsen significantly over time.

Expansion of the 161-kilovolt system that will interconnect the proposed Cheatham County Gas Plant will have many benefits such as:

  • Reduce FIDVR issues in the Middle Tennessee area.
  • Add capacity to the transmission system to serve future load growth.
  • Provide continued stability of the transmission system.
  • Support greater levels of solar and battery storage integration.
  • Reduce region dependence on Gallatin Fossil Plant.

TVA is proposing to build the Cheatham County Substation at the proposed Cheatham County Generation Facility off Lockertsville Road.  TVA also proposes to build three double-circuit power lines to loop or connect three existing nearby power lines to the new substation.  The three existing TVA lines are the Montgomery-Springfield 161-kilovolt Transmission Line (Line 5810), the West Nashville-Clarksville 161-kilovolt Transmission Line (Line 5162), and the Davidson-West Nashville 161-kilovolt Transmission Line (Line 5689).

Phase 1

  • The approximate length of the proposed loop from the West Nashville-Clarksville 161-kilovolt Line (Line 5162) would be 2.5 to 3.5 miles long and consist of 5 alternative segments and 3 alternative routes.

Phase 2

  • The approximate length of the proposed loop from the Montgomery-Springfield 161-kilovolt Line (Line 5810) would be 14 to 17 miles long and consist of 32 alternative segments and 112 alternative routes.
  • The approximate length of the proposed loop from the Davidson-West Nashville 161-kilovolt Line (Line 5689) would be 15 to 17 miles long and consist of 18 alternative segments and 24 alternative routes.

The alternative loop connection point for the Montgomery-Springfield Line (Line 5810) would be at the Coopertown Metering Station.  There are three alternative loop connection points for the West Nashville-Clarksville Line (Line 5162) and one alternative loop connection point for the Davidson-West Nashville Line (Line 5689).

The new double-circuit lines would be built using primarily double-pole (H-frame), steel structures with potential for steel towers in mountainous areas.  Structures would be centered on existing and new 100-foot-wide right of way.  New 187.5-foot-wide right of way would be used where proposed routes parallel each other.  Phase 1, which includes the proposed Line 5162 loop line, has a tentative completion date of no earlier than 2028.  Phase 2, which includes the proposed L5810 and Line 5689 loop line, has a tentative completion date of no earlier than 2029.  (Dates are subject to change. Unexpected issues may arise, resulting in the need to adjust the schedule.)

Property owners near and along the alternative transmission line segments have been invited to an open house by mail – including about 391 property owners representing about 479 parcels.  At the open house on Wednesday and Thursday, March 6-7, 2024, TVA representatives will provide information, answer questions and receive comments about the proposed transmission project.  For those unable to attend the open house March 6-7, 2024, TVA is providing a virtual open house from March 6 through April 8, 2024, online at  tvavirtual.com/MiddleTN.

Environmental Reviews

The appropriate National Environmental Policy Act review will be conducted to ensure that the environmental impacts are minimized. TVA attempts to minimize any land requirements, private property impacts, and environmental impacts associated with this project.

Efforts are made during the siting process to avoid or minimize impacts to floodplains and wetlands in accordance with Executive Orders 11988 and 11990. Floodplains and wetlands are shown on the referenced map. The map illustrates how the route avoids or impacts floodplains and wetlands. Because of project and topographic constraints and because of minimizing impacts to other social, environmental, and engineering resources, no practicable alternative may be available that would allow complete avoidance of impacts to floodplains and wetlands which may require mitigation for minimizing impacts. Also, best management practices would be utilized throughout the project to minimize adverse floodplain and wetland impacts. In compliance with Section 404 of the Clean Water Act, TVA will be coordinating wetland findings with U.S. Army Corps of Engineers.

The NEPA review for this project will be incorporated into the Cheatham County Generation Site Environmental Impact Statement (EIS), which can be found at the Cheatham County Generation Site once it is available.

Middle Tennessee Generation and Transmission Capacity Expansion Project (Cheatham and Robertson Counties)

Update – April 2024

TVA has identified the preferred location for a power line that would provide power for growing load and increase power reliability in the Cheatham County area of Middle Tennessee.

TVA evaluated each route using social, engineering, and environmental factors.  Information sources included available data, aerial photography, limited onsite reviews, public review and comment, and property owner input.  Based on public input and evaluation, the preferred route is expected to have the least overall project impact of the alternatives.

TVA’s proposed 3.08-mile line would begin at TVA’s existing West Nashville-Clarksville 161-kilovolt Transmission Line, north of Sweethome Road, and would end at TVA’s Cheatham County Substation located at the proposed Cheatham County Natural Gas Generation Facility on Lockertsville Road.

The route selected is Route No. 1 consisting of Loop Point No. 1 and Segment Nos. 33 and 37 as presented at the open house in Ashland City March 6 and 7, 2024, and online at the virtual open house from March 6 through April 8, 2024.

The new line will be built using primarily double-pole (H-frame), steel structures with potential for steel towers in mountainous areas.  Structures would be centered on new, 100-foot-wide right of way.  There is potential for an additional 87.5-foot width when Phase 2 routes are announced in areas where parallel options were presented.

Surveys of the right of way are scheduled to begin in winter 2024-2025.

The line is scheduled to be in service no earlier than 2028.

The National Environmental Policy Act review is pending.

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Cheatham and Robertson County areas of Middle Tennessee.

The planned retirement of TVA’s Cumberland Fossil Plant creates the need to add new generation to the TVA system at a location that will provide reliable electric power to the Middle Tennessee area for decades to come.  Leveraging of the existing 161-kilovolt transmission infrastructure in the area, increasing Middle Tennessee electrical power demand, existing TVA-owned property, and maintaining system stability by providing grid support are criteria that make Cheatham County an ideal location for a proposed new, gas-powered generation plant.

The Middle Tennessee area can experience an issue known as fault-induced delayed voltage recovery (FIDVR) when certain 500-kilovolt transmission lines are removed from service by a storm, planned maintenance outage, or some other event.  When FIDVR occurs, it can lead to area instability and potential blackouts.  New generation on the 161-kilovolt system (e.g., proposed Cheatham County Gas Plant) would reduce the likelihood and severity of FIDVR events.

Inverter-based resources (IBRs), such as solar generation and battery storage, do not support the stability of the transmission system like traditional spinning generation.  IBRs are also typically located farther away from densely populated areas due to geography and land availability.  As more legacy fossil plants (i.e., spinning generation) are retired and more IBRs are added to the system, replacement generation moves away from load centers.  As a result, stability concerns such as those seen in Middle Tennessee worsen significantly over time.

Expansion of the 161-kilovolt system that will interconnect the proposed Cheatham County Gas Plant will have many benefits such as:

  • Reduce FIDVR issues in the Middle Tennessee area.
  • Add capacity to the transmission system to serve future load growth.
  • Provide continued stability of the transmission system.
  • Support greater levels of solar and battery storage integration.
  • Reduce region dependence on Gallatin Fossil Plant.

TVA is proposing to build the Cheatham County Substation at the proposed Cheatham County Generation Facility off Lockertsville Road.  TVA also proposes to build three double-circuit power lines to loop or connect three existing nearby power lines to the new substation.  The three existing TVA lines are the Montgomery-Springfield 161-kilovolt Transmission Line (Line 5810), the West Nashville-Clarksville 161-kilovolt Transmission Line (Line 5162), and the Davidson-West Nashville 161-kilovolt Transmission Line (Line 5689).

Phase 1

  • The approximate length of the proposed loop from the West Nashville-Clarksville 161-kilovolt Line (Line 5162) would be 2.5 to 3.5 miles long and consist of 5 alternative segments and 3 alternative routes.

Phase 2

  • The approximate length of the proposed loop from the Montgomery-Springfield 161-kilovolt Line (Line 5810) would be 14 to 17 miles long and consist of 32 alternative segments and 112 alternative routes.
  • The approximate length of the proposed loop from the Davidson-West Nashville 161-kilovolt Line (Line 5689) would be 15 to 17 miles long and consist of 18 alternative segments and 24 alternative routes.

The alternative loop connection point for the Montgomery-Springfield Line (Line 5810) would be at the Coopertown Metering Station.  There are three alternative loop connection points for the West Nashville-Clarksville Line (Line 5162) and one alternative loop connection point for the Davidson-West Nashville Line (Line 5689).

The new double-circuit lines would be built using primarily double-pole (H-frame), steel structures with potential for steel towers in mountainous areas.  Structures would be centered on existing and new 100-foot-wide right of way.  New 187.5-foot-wide right of way would be used where proposed routes parallel each other.  Phase 1, which includes the proposed Line 5162 loop line, has a tentative completion date of no earlier than 2028.  Phase 2, which includes the proposed L5810 and Line 5689 loop line, has a tentative completion date of no earlier than 2029.  (Dates are subject to change. Unexpected issues may arise, resulting in the need to adjust the schedule.)

Property owners near and along the alternative transmission line segments have been invited to an open house by mail – including about 391 property owners representing about 479 parcels.  At the open house on Wednesday and Thursday, March 6-7, 2024, TVA representatives will provide information, answer questions and receive comments about the proposed transmission project.  For those unable to attend the open house March 6-7, 2024, TVA is providing a virtual open house from March 6 through April 8, 2024, online at  tvavirtual.com/MiddleTN.
