RIGGSVILLE-PORT CALCITE

Riggsville – Port Calcite – Rockport Transmission Line Rebuild

In order to improve the reliability of high voltage electrical service in northern Michigan, ITC Michigan, through its Michigan Electric Transmission Company (METC) subsidiary, is rebuilding approximately 70 miles of the Riggsville – Port Calcite – Rockport 138,000 volt (138 kV) double circuit transmission line spanning the northeast lower peninsula. Construction is ongoing on the 24-mile Port Calcite – Rockport line, followed by the 45-mile Riggsville – Port Calcite line. The existing wood poles will be replaced with steel monopoles with new conductor (wires). The entire project is expected to be completed in 2023.
