Objectives

  • Identify highest emitting (>10 cu. ft./ hr) “super emitter” leaks for targeted replacement to satisfy regulated emissions reduction requirements.

ROI

  • In one year, 210 of the highest emitting leaks were identified by Picarro emissions quantification measurements.
  • These 210 leaks represent 49.7 Million cu.ft./yr (32%) of total emissions. 

Highlight

In 2019, the utility used Picarro to measure one-third of their infrastructure for compliance leak survey and two-thirds of their infrastructure for a Super Emitter survey.

This emissions quantification at scale allowed a methane map to be built for the entire infrastructure (useful for forecasting in later leak survey compliance seasons). It was also used for identification and remediation of the highest-emitting leaks which provided both environmental and risk reduction benefits.
