Keystone-Hodenpyl Transmission Line Rebuild
Portions of the electric transmission grid in northwestern Michigan were built in the 1950’s and 60’s and have experienced minimal investment since that time. The lines and structures on the Keystone-Hodenpyl 138,000 volt (138 kV) line reached their design capacity limits and became difficult to maintain. METC upgraded this 26-mile line in order to improve…
