National Grid Electric Distribution Program

National Grid -- New England

CHA has worked on a variety of National Grid electric distribution programs and projects, including running the Feeder Hardening program in New England. CHA has been responsible for performing feeder inspections, making recommendations to improve system reliability and safety, designing circuit upgrades in Grid’s GIS design system, completing as-builts, and closing out completed work. CHA has also monitored the scope, schedule, and cost of the program. Throughout the program, 250 feeders and 7,100 miles of overhead distribution were hardened. Other program work includes overloaded transformer replacements and side tap fusing surveys.

CHA has also worked with Grid on Department of Transportation (DOT) relocation projects in New England. For these, CHA designed the relocation of their assets to accommodate proposed modifications to state roads and bridges. Throughout the process CHA reviewed DOT plans and consulted with their engineers to ensure designs met the needs of DOT. CHA has also done numerous design projects including feeder reconductoring, new feeder ties, voltage conversions, and substation getaways.
