Quanta Services, a contracting services company delivering infrastructure network solutions, and Northeast Utilities (NU) have announced the addition of $200m in services and an extension of two years to their existing multi-year contract under which Quanta is providing transmission infrastructure services related to NU’s transmission build-out through 2015.

The anticipated value of the original contract, signed in December 2007, was $750m and it extended from 2008 to 2013. With this recent expansion, the anticipated value of the contract is now $950m through 2015.

Under the now eight-year contract, Quanta will continue to provide labor, equipment and general project management for NU’s transmission projects throughout New England.

Charles Shivery, chairman, president and CEO of NU, said: A strong transmission grid is vital to New England’s safety, security and economic prosperity. Quanta’s proven expertise in transmission infrastructure services, nationwide scope and large workforce are key elements in solving the transmission limitations in New England.

John Colson, chairman and chief executive officer of Quanta Services, said: “We share NU’s commitment to strengthening electric reliability and helping New England meet the region’s aggressive energy, environmental and economic goals. As a regional and national transmission leader, NU is working to develop New England energy solutions from diverse sources. We are committed to enhancing the transmission infrastructure to improve that access.”
