O'Connell has over 75 years experience constructing the power line collection, transmission, and distribution systems that supply electrical energy from power generation sources to customers across the northeastern United States. We provide turnkey solutions for any size transmission and distribution project and are mutual aid responders, providing power restoration services in emergency situations.

O'Connell has a knack for taking on large, challenging projects and leveraging them to strengthen and expand our service offerings. Case in point: for the 1980 Winter Olympics in Lake Placid we tackled the rugged terrain, steep granite faces, and treacherous weather conditions of Whiteface Mountain, installing overhead, underground, and surface-mounted cable, from base to peak. When the U.S. Army moved to expand its Fort Drum military base, O'Connell jumped at the chance to take on the massive distribution project  encompassing over 500 square miles.

We have established a reputation among our customers for providing quality, reliable overhead and underground power line systems on schedule and within budget. Our experienced and highly trained personnel, modern tools, construction equipment, and diverse fleet of vehicles provide us with the capability to handle power line transmission and distribution work of any size, scope, and complexity.
