PSE&G Develops Advanced Leak-Detection Methods to Reduce Urban Methane Emissions

Persistent, non-hazardous leaks are a ubiquitous problem in many urban gas distribution systems—with leaks often going unaddressed for years because they don’t present an immediate danger to people or property. Using advanced analytics and leak data collected by Google Street View vehicles outfitted with methane detection sensors, PSE&G— New Jersey’s largest natural gas utility—was able to identify and prioritize replacement of its highest emitting areas, leading to an 83 percent reduction in methane emissions by replacing one-third fewer miles of pipe than would have been required using traditional survey and repair methods.

"PSE&G, working with EDF and Google, pioneered the use of advanced leak detection methods by using methane emissions data to help prioritize our pipe replacement efforts on the areas most in need. Targeting and accelerating the replacement of our aging pipes provides benefits for our customers, the economy and the environment."
