West Main Natural Gas Pipeline Replacement Project

We are working to provide safe, reliable service



As part of our Pipeline Integrity Management Program, we will replace approximately 77 miles of 95 miles of high pressure transmission pipeline between Westminster, Colo., and the Wyoming border. The additional pipe will be abandoned or switched to distribution uses. This work will ensure safe, reliable service to our current and new customers along the Front Range.

Work in Larimer and Weld counties started in 2012 and is expected to continue through 2015. Work in Boulder County is expected to start in 2015 and continue through 2016.

This project is one of a package of pipeline integrity management programs and projects that are funded by the Pipeline System Integrity Adjustment (PSIA) rider that appears as a separate line item on Xcel Energy's natural gas customers' bills. We anticipate that in 2014, on a monthly bill, it will cost an average residential customer using 62 therms a month 36 cents, and the average small business customer using 270 therms a month $1.56.
