To be a player in the power generation, transmission and distribution marketplace, and be efficient at it, contractors must have the right equipment on hand as well as sizable bonding capacity.  O'Connell has both.

Our Substation Division experienced sizable growth through the 1970s due to a boom in the hydroelectric plant sector.  Similarly, opportunities for our Power Line Division increased substantially after we conquered Whiteface Mountain in preparation for the 1980 Winter Olympics.  Our Technical Services Division continues to expand its reach as needs grow within the industry for comprehensive testing, commissioning, and preventative maintenance services.

Today, the combined expertise and resources of this trio enable O'Connell to provide turnkey solutions for transmission/distribution projects of any size, scope and complexity.  Our substations, switchyards, and relay stations can be found managing T&D networks throughout the northeast while our overhead lines and underground cables are carrying power over thousands of circuit miles.

O'Connell has an established reputation for providing quality, reliable power systems on schedule and within budget.  We boast one of the most experienced, highly trained workforces in the region, utilizing a comprehensive collection of modern tools and construction equipment supported by a diverse fleet of vehicles. 

Moving forward, O’Connell is prepared to support and implement new "smart grid" technology and construction to help build the robust US electrical power grid of the future.

Sectors of the power industry that O'Connell services include power generating facilities, transmission systems, distribution systems and collection systems.  Our customers range from public utilities and municipalities to independent developers and private concerns.
