Power Supply Upgrade

Update December 2013

TVA has completed construction of the 4.75-mile transmission line to supply power to Pennyrile Rural Electric Cooperative Corporation's new substation in the Salem Church community near Oak Grove, Kentucky. The new facilities are expected to go into service in January 2014.

July 2011

TVA has evaluated 12 alternative line segments for improvements that will relieve equipment that is near overload and provided continued reliable power.

Based on public input, TVA has identified a modified version of alternative route segments as the preferred route, as shown on the preferred route map below. The line would begin at alternative tap point #3 on TVA's existing Edgoten-Casky 161-kilovolt tap line. The route follows the existing right of way north for about 1500 feet, then turns west towards Highway 41, mostly following farm and property boundaries until it crosses the railroad. There the route turns south for about 1200 feet and ends at the substation.

The same considerations — environmental, land-use, engineering, and cultural — were used to assess each alternative. The reviews were based on available data, aerial photography, onsite reviews, public comment, and property owners’ input.

The preferred route is about 4.75 miles long and is expected to have the least overall impact of the alternatives. In keeping with TVA's environmental stewardship, an appropriate National Environmental Policy Act review will be conducted.

The line would be built on steel poles on a 100-foot right of way.

Eleven property owners (17 property tracts) would be affected.

Construction is scheduled to begin fall of 2013 with the news facilities in service the winter of 2013-14.

March 2011

TVA is considering improvements to the transmission system near Oak Grove, Kentucky, located south of Hopkinsville, between Fort Campbell and Pembroke, Kentucky. The improvements will provide continued reliable power to the area.

Pennyrile Rural Electric Cooperative Corporation’s demand on the TVA Edgoten Substation is expected to exceed the available capacity of the transformer bank by winter 2014. TVA proposes to serve their new Salem Church Substation from a different source, thereby relieving load on the Edgoten Substation.

TVA held an open house on March 24, 2011 to provide information, answer questions and accept comments about the proposed project.

The proposed project consists of about 4.5 miles of new transmission line to power Pennyrile Rural ECC’s proposed Salem Church Substation. TVA would power the substation with a new single-circuit 161-kilovolt transmission line, which would extend from the existing Edgoten-Casky 161-kV line west towards Highway 41 to the new Salem Church Substation, located on Elmo Road near the CSX Railroad.

Several alternative routes from a network of twelve alternative line segments will be presented at the open house. Some of the alternative segments use existing right-of-way.

The transmission line would consist of a single-circuit line and steel structures on a 100-foot right-of-way.

The project is scheduled to be completed winter of 2013-2014.

Public involvement

TVA’s process for siting new transmission projects is designed to allow public input at all stages. TVA is committed to working with area stakeholders to address concerns during the course of the project. Comments received during the comment period will be used in reaching a decision on the proposed action.

TVA held an open house to discuss the proposed transmission line project. The open house was held Thursday, March 24, 2011 at the Pembroke Elementary School gymnasium in Pembroke, Kentucky. A 30-day comment period followed.
