Gas Leaks

HEET’s program to cut emissions from natural gas (methane!) leaks now

Politicians, utilities, and people with noses had recognized that Massachusetts had a problem with gas leaks for some time. HEET resolved to do something about it. In 2015 HEET commenced a program to cut these emissions from natural gas. 

The documents listed below show the progression in HEET’s work. The 2017 Shared Action Plan was a watershed moment when the utilities agreed to have HEET verify Massachusetts gas utilities work to identify and repair natural gas leaks of “significant environmental impact (SEI).”  SEI leaks are the 7% of all the leaks that emit half of the gas by volume. 

Gas Leak Maps

Gas companies in Massachusetts must report their natural gas leaks by location each year. HEET extracts, cleans and maps these data and makes them available both as maps and as geocoded GIS data.

Emissions data is approximated for each town using the Lost and Unaccounted for (LAUF) gas calculator.

Please contact us directly if you would like a copy of map data.

Salem, Massachusetts has used a copy of data for their town to inform citizens, plan for tree planting, and prepare for fire hazards. 

Gas Leaks maps may be freely shared, although they are not Creative Commons licensed (as the map tool and interface are (c) Google and its partners).

Gas Pipe Replacement (GSEP) Plans 

Gas companies in Massachusetts are currently in the midst of replacing about a quarter of all gas infrastructure through the Gas System Enhancement Plan (GSEP). This program is carried out at a high cost to ratepayers. HEET extracts, cleans and maps these data annually to make them available both as maps and as geocoded GIS data.

Energy Shift

The transition to clean, renewable energy. 

GeoMicroDistrict

HEET has designed a networked geothermal system that can be installed and owned by gas companies in the street right-of-way, transforming gas utilities from obstacle to accelerator.

Community Charrettes

HEET is hosting charrettes each month throughout 2021 in an effort to share information and learn from all to make the GeoMicroDistrict demonstration projects the best they can be. After each Charrette, we generate a report with significant takeaways. Reports are shared with Eversource, state regulators, and others.

Charrette #2 Data Collection Report

Taste the Future Induction Cooking Parties

A key barrier to transitioning from gas to renewable energy is the stove. Although some residents don’t care about how their home or water is heated, many people believe that cooking with gas is the best way to cook. Luckily, cooking with induction is significantly faster, more precise, and safer!
