O'Connell Electric has been constructing substations, switchyards, and relay stations for nearly 80 years. Our comprehensive electrical construction services provide the foundation for medium, high, and extra high voltage collection, transmission, and distribution systems. Our broad experience working with public utilities, municipalities, and independent developers makes us uniquely qualified to meet the challenges of your transmission or distribution project.  We specialize in providing fast, reliable grid connection.

O'Connell is always up for a good challenge. We won the bid for prime electrical contractor in charge of repowering the Village of Lake Placid, Whiteface Mountain, and the Olympic Village to prepare for the 1980 Winter Olympics. We built new substations, upgraded all existing systems, and set transformers at the summit of Whiteface.  The project was instrumental in elevating our capabilities (literally) and opened new doors for the division.

Over the decades we have built our expertise and capability through hundreds of medium to extra high voltage substation construction, upgrade, and retrofit projects. Our customers span industrial and commercial businesses, educational institutions, developers, public utilities, and government.
