  • An expansion of the existing Campbell Substation in Pine Township, Mercer County;
  • Rebuilding the existing Campbell-Keister 69-kV transmission line in Butler and Mercer counties for 138-kV operation; 
  • Replacing the existing structures and single circuit Campbell-McDowell 69-kV line in Mercer County with 69-kV and 138-kV lines supported on the same structures.
