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 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.

The average customer cost for an excess flow valve is approximately $1,100, but the actual cost may vary due to installation conditions.  

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 excess flow valve. 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

Install ceiling fans to keep cool air circulating so you can turn down your air conditioner. Still, make sure to turn off your fan when you leave the room.


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.
