Calpine Morgan Energy Center - Request to Provide Interconnection

Final Environmental Assessment


TVA has prepared an environmental assessment of the proposed interconnection of Calpine’s Morgan Energy Center generating plant to TVA’s transmission system at General Motors Substation. TVA would construct 12.0 miles of new 161-kV transmission line on existing right-of-way and 3.8 miles on new right-of-way 100 feet in width in northern Morgan and southern Limestone counties, Alabama.


The environmental assessment can be viewed by section, as noted below (PDF files, require Adobe Acrobat Reader).

Finding of No Significant Impact (232 kb)
Based on the final EA, TVA issued a finding of no significant impact (FONSI) on October 10, 2003.  This document explains TVA’s decision to provide interconnection between Calpine’s Morgan Energy Center and the General Motors Substation on the TVA transmission system. With mitigation to minimize impacts to an archaeological site, there will be no significant adverse impacts on the environment. The entire FONSI can be viewed here.
