Stamford Gas ​Reliability Project

Eversource is making infrastructure improvements to benefit downtown Stamford, while increasing gas supplies and strengthening the reliability of our system.  Our work will ensure customers have reliable ​gas service to meet their energy needs, today and in the future.

The Stamford Gas Reliability Project will improve the natural gas distribution system in the downtown business area. Known as “The City That Works,” Stamford has a robust business community that counts on reliable gas service for its economic growth.

We will be replacing existing cast iron and bare steel gas main with newer plastic pipe - which is safer, more durable and better able to handle fluctuations in underground temperatures. The new mains will allow for higher gas pressures and increased supply to better handle the needs of Downtown Stamford. 

We have been working in close collaboration with the City of Stamford and the Downtown Special Service District (DSSD) to expedite this project and minimize any disruption that may be experienced by residents, business owners and the general public.
