UNIT SUBSTATION RETIREMENTS

MasTec Professional Services engineered more than 100 miles of substation retirement and feeder upgrades for a large Northeastern U.S. utility, delivering modernized infrastructure and improved system reliability.


Our scope included complete overhead and underground design services—reconductoring, pole replacements, transformer upgrades, and updated protection schemes with new or reprogrammed devices. We also engineered new aerial and underground feeder routes to support higher-voltage conversions.


Designs addressed the needs of multiple commercial customers and included civil work for new duct banks, underground installations, and safe facility abandonment.
