A total of $254m will be invested by Rochester Gas & Electric and Iberdrola USA to upgrade the electric transmission system, which serves customers in the City of Rochester and western Monroe County.
Sertex president Michael Solitro said: "We’re pleased to be awarded the first contract in this important project and we appreciate RG&E’s confidence in Sertex."
