Bullet slideOptimizing Leak Abatement with Improved Leak
Data Acquisition and Analysis
AGA State Affairs Committee Meeting- Oct. 10, 2016
N. Jonathan Peress
Environmental Defense Fund
Overview: Utilities and PUCs seeing the
benefits of Spatial Analytics
• PSE&G/EDF leak survey prioritization project complete; informs cost effective program implementation and emission reductions
• Advanced leak detection finds more leaks, enhances program effectiveness (e.g., Centerpoint)
• Spatial analytics (i.e., new data gathering, processing and visualization methods) like EDF PSE&G project improving utility decision-making and program management (e.g., PWC)
• Additional utilities integrating leak data acquisition, analysis and methane emissions into leak abatement program implementation (e.g., National Grid, PG&E)
• Begin with state regulatory backdrop
A small fraction of sites and components contributes the majority of emissions.

New locational methods and sensors (e.g., Picarro) being integrated by utilities
• PG&E, CenterPoint Energy, EDF UNU analysis finds 3 to 5 times more leaks than standard (e.g., FI)

Picarro Enterprise Value Proposition
Picarro Implementation Significantly
Reduces Leaks
Picarro Analytical Mode Proactive Pipe
Replacement Significantly Reduces Leaks

September 2016 – Proposed Settlement
• Methane emission flow rate data in prioritizing leak prone pipe replacement
• Integrate leak flow rate quantification into leak abatement program
• Revenue incentive for targeting and repairing leakiest pipe segments
How spatial analytics can empower asset management for gas utility companies PWC – April 2016
• “By integrating spatial analytics’ predictive modelling with risk-based integrity management programs, utilities can meaningfully improve their asset integrity, investment decisions and deployment of people, processes and technologies.” –Source: PWC
Advancing Solutions (with information)
• Utilities, stakeholders, regulators and public benefit from information.
• Resolve disconnect between infrastructure condition (leaks) and expenditures.
• Enhance project management, leak reductions and cost-effectiveness.
• What leaks can and should be repaired, mains replaced? Utility experience validates that data acquisition, quantification, spatial analytics can be used to manage and prioritize.
• No longer just about research and pilot projects; utilities around the country are operationalizing.
