Under the contract, TRC will engineer, procure and construct a new electric substation to replace National Grid’s existing South Street Station in Rhode Island, in order to enhance efficiency.

The company will be responsible for providing an all new control and switchgear building and adjacent yard; conversion of existing overhead line supply circuits to underground cable circuits as well as re-route of the existing underground feeder facilities to the new substation.

The contract scope also includes performance of related substation modifications at remote substation terminals as well as removal of existing overhead line circuits, unused portions of existing feeder getaways and substation facilities including the existing switchgear building.

TRC Companies chairman and CEO Chris Vincze said: "As energy companies continue to tackle the issue of aging infrastructure and reliable service, TRC is dedicated to providing our utility clients with technical expertise and creative solutions to better serve their customers and the communities in which they work."

TRC said that the contract is expected to ensure safe, efficient and reliable electricity for National Grid’s customers, including the City of Providence and much of the downtown Providence area.

The project’s design and engineering has already commenced and is due to be complete in early 2016.

TRC plans to fully commission the new station and restore the site to its original state by the end of summer 2019.

The contract is a part of a four-year, multi-faceted project, which involves installation of 165MW of 115kV transformation.
