Unitil Deploys Advanced Mobile Leak Detection Vehicle to Reduce Methane Emissions
UNITIL Corporation has deployed an Advanced Mobile Leak Detection (AMLD) system in its New England natural gas service areas to identify and measure methane emissions. Following a successful pilot in Massachusetts, operations have expanded to Maine and New Hampshire, surveying the network at night from spring to fall. The Picarro-supplied technology allows for real-time detection of gas leaks, with 36% of emissions traced to just 11% of leaks, enabling targeted repairs. More details will be in the 2025 Corporate Sustainability & Responsibility Report.
UNITIL Corporation has announced the deployment of a new Advanced Mobile Leak Detection (AMLD) system across its natural gas service territories in New England. The system, installed on a specially equipped vehicle, is designed to efficiently identify and measure fugitive methane emissions from the company’s gas distribution network. After piloting the program in Massachusetts in 2023, UNITIL expanded AMLD operations to Maine and New Hampshire, surveying the entire network during nighttime hours from early spring to fall. The technology, supplied by Picarro, enables real-time detection and measurement of gas leaks. According to UNITIL, approximately 36% of total emissions were traced to 11% of leaks, allowing for targeted repairs and emission reductions. Additional details are available in the company’s 2025 Corporate Sustainability & Responsibility Report.
