Madison-Charity Lane 161,000-volt Transmission Line

Madison County, Alabama

The Tennessee Valley Authority (TVA) has issued an environmental assessment (EA) and finding of no significant impact for the proposed construction and operation of a new 161-kilovolt (kV) transmission line.  The new Madison-Charity Lane 161-kV Transmission Line would supply electric power to the new Charity Lane 161-kV Substation, planned for development by Huntsville Utilities (HU), a local distributor of TVA power.  The substation would be constructed east of HU’s existing Charity Lane 46-kV Substation, at the intersection of U.S. Highway 231 and Charity Lane.  The new transmission line would connect HU’s planned substation to TVA’s existing Madison 500-kV Substation.  HU has requested that the new transmission line be completed by December 2014.

To accommodate the proposed transmission line, TVA would construct a new breaker bay at its Madison 500-kV Substation.  Two transmission lines would be reconfigured on substation property to efficiently terminate into the Madison 500-kV Substation.

In anticipation of meeting future power load growth in the area, the proposed action also includes the purchase 0.75 miles of new 75 foot-wide ROW parallel to TVA’s existing Madison-West Point 500-kV Transmission Line.  This additional ROW area would allow TVA to plan for future transmission system needs.  TVA would provide revenue metering equipment to HU for installation at the Charity Lane 161-kV Substation.  The TVA map board displays would be updated with the new transmission assets.

Additional information on the project is available, including background information, maps, and a project schedule.
