CL&P transmission upgrade completed in Stamford

Stamford Reliability Cable Project strengthens grid reliability with a 1.5-mile transmission upgrade through downtown Stamford, tunneling under Metro-North, routing near the Urban Transitway, and connecting Glenbrook and South End substations.

BERLIN, Conn. – After nearly nine months of intense construction in a busy section of Stamford, Connecticut Light & Power has completed the Stamford Reliability Cable Project ahead of schedule and under budget. This project is part of a long-term plan to improve electric reliability to the power grid that serves the growing needs of Stamford and surrounding area.

The approximate 1.5 mile transmission project route threads through downtown, and important commuter rail and highway corridors connecting two existing substations in the Glenbrook and South End neighborhoods. This active area presented unique construction challenges that were met by the project team with several creative solutions that included:

- Tunneling under the Metro-North Railroad right of way to avoid impacts to commuters

- Routing around the Stamford Urban Transitway, the city’s roadway improvement project between East Main and Atlantic streets

- Customizing street work hours to minimize impacts to residential and business neighbors

“The Stamford Reliability Cable Project continues CL&P’s strong track record of making targeted investments to improve our system,” said Dwayne Basler, Vice President of Transmission Projects, Engineering & Maintenance for Northeast Utilities, parent company of CL&P. “These investments ensure reliable, cost-effective energy for our customers and support the continued economic growth in southwest Connecticut.”

The Stamford Reliability Cable Project is part of a series of upgrades to CL&P’s electric system in the Stamford and surrounding area. Together these projects will improve reliability of service and meet the growing customer demand for power, aligning with efforts to storm-proof distribution systems across major utilities and lessons from Hurricane Sandy about grid resilience.
