Natural Gas Excess Flow Valves and Eligibility

Xcel Energy’s residential, multi-family, and small commercial customers can now request installation of an excess flow valve (EFV) on their natural gas service lines. A new regulation from the federal Pipeline and Hazardous Materials Safety Administration has expanded the use of these valves, which have been installed on new or replacement services lines for the past several years.

An EFV is a safety device installed inside a natural gas service line near its connection with our underground main pipeline, typically in or along streets. The purpose of the valve is to shut off the flow of natural gas automatically in the event of a gas line break caused by excavation or other activities that could sever a service line.

While any customer can request an EFV, not all existing service lines can be retrofitted to accommodate one. The amount of natural gas used by the customer and the system pressure inside the line are two determining factors.

Customers requesting the installation of an EFV will be responsible for the costs of excavation and surface restoration related to the installation of the EFV.  The average customer cost for an EFV is approximately $1,000, but the actual cost may vary due to installation conditions. Costs to maintain or replace an EFV may later be incurred, but the requesting customer will not be responsible for those costs.

Please call Xcel Energy’s Builders Call Line at 800-628-2121 to speak with an Xcel Energy representative if you are interested in an EFV. We will determine if your existing service line qualifies for the installation of an EFV before working with you to set an installation date.

Energy Saving Tip

Turn off your lights when you leave the room—even if you'll only be gone for a moment. Contemporary light bulbs require very little energy to turn "on."

Break Ground, Not the Law

Always call 811 before digging in your yard to avoid hitting buried gas or electric lines. Not only is it the safe thing to do, but it's the law.
