Energy engineering, consulting and construction firm TRC Companies, won a contract to engineer, procure and construct a new electric substation in downtown Providence, Rhode Island, to replace National Grid’s existing South Street Station.

This award represents the primary outsourced solution to completing a four-year, multi-faceted project, which includes the installation of 165 MW of 115 kV transformation. The new substation will support National Grid‘s customers, including the city of Providence and much of the downtown Providence area, with safe, efficient and reliable electricity for years to come.

“TRC is proud to expand our long-standing relationship with National Grid by supporting them on this critical project,” said Chris Vincze, Chairman and CEO. “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.”

Under the contract, TRC will construct a new South Street Substation. Among other things, the work is planned to include an all new control and switchgear building and adjacent yard; conversion of existing overhead line supply circuits to underground cable circuits; re-route of the existing underground feeder facilities to the new substation; performance of related substation modifications at remote substation terminals; and removal of existing overhead line circuits, unused portions of existing feeder getaways and substation facilities including the existing switchgear building.

Replacing the aging substation with new equipment and materials will improve efficiency and support National Grid’s delivery of safe and reliable electricity to its customers. The project will also improve the environment and enhance skyline and river views by removing existing steel transmission towers.

Design and engineering for the project has begun and is expected to be complete in early 2016. The project is well into the permitting phase for regulatory and municipal approvals. The remaining construction, transmission installation and demolition activities will take place over three years and will commence upon receiving all needed permits. The new station is expected to be fully functional and the site restored to its original state by the end of summer 2019.
