SURE Project

Mainers, we’ve completed the 14-year SURE project!

The System Upgrade for Reliable Energy (SURE) improvement project began in 2011 as Unitil replaced and upgraded 126 miles of natural gas pipeline throughout Portland and Westbrook, Maine.

A safer, more reliable system for coastal Maine.

By replacing the aging cast iron and bare steel pipes before they became a concern the system will be able to operate at a higher pressure reliably. An additional 10,000 automated shut-offs were also installed to help keep homeowners safe in the event of a widespread gas outage.

The new pipelines meet the growing energy demands of Southern Maine and allow the delivery of natural gas to be even more reliable and efficient.
