A new method of prioritizing gas infrastructure improvements is resulting in faster reductions of greenhouse gas emissions in New Jersey. Just over a year ago, we wrote about an order from the state’s Board of Public Utilities approving a settlement agreement for a $905 million, three-year pipe replacement program by PSE&G, New Jersey’s largest gas utility. This order, and the underlying settlement agreement were pioneering in one major aspect – PSE&G agreed to use environmental data to inform its infrastructure improvement efforts.
The order provided that the company would use data on leak flow rate (the speed at which methane is leaking from gas pipes) to help prioritize its local distribution pipe (“gas line”) replacement program. PSE&G is the first utility in the country to do so. The idea was that this data would be gathered by EDF as part of a collaborative project with Google Earth Outreach and Colorado State University through a survey of sections of PSE&G’s service territory targeted for gas line replacement.
