To the Editor:

Liberty has racked up endorsements for Granite Bridge from a bipartisan group of 22 New Hampshire senators, backing from the labor unions, has held 75 meetings with town officials along the route, and three Chambers of Commerce (Nashua, Manchester and Concord) have intervened in the Granite Bridge docket before the Public Utilities Commission as supporters of the project.  In addition to the millions of dollars being promised in tax revenues for the towns, Governor Sununu fully supports the project.

Many supporters reference the environmental benefit of switching from oil to gas heating.

Although burning gas produces 27 percent less CO2 than heating with oil, that doesn’t account for the impact of methane leaked from the distribution system. And, the leaks in Liberty’s system are significant!  According to Liberty’s 2017 Annual Report (page 49), they had “Unaccounted for Volumes” of 2.2 percent statewide. Methane or CH4 is a much more powerful Greenhouse Gas than CO2 over the first 20 years.

A major policy problem in the NHSAVES program makes it impossible to recommend a high efficiency air source heat pump as a more sustainable, lower cost heating option than oil.  For a look at the relative costs of different heating options, people can visit efficiencymaine.com

Since Liberty customers pay for the “unaccounted for volumes,” and the leaked gas impacts the climate, perhaps Liberty should release a detailed report and supporting data explaining the losses?
