National Grid is proposing a “fossil free” gas system to continue providing heat and energy to its customers across the Northeast. “Renewable natural gas is a way of capturing those methane emissions that would occur naturally in water treatment facilities, at landfills, on farms, and instead of it venting into the atmosphere, us capturing it, repurposing it for use in the network, and then it displaces geological natural gas.” What National Grid is calling for “We believe this is something that has to be relooked at in New York state,” he said. Wynter said no other state uses the 20-year global warming potential and treats renewable natural gas nearly the same as geologic gas. National Grid’s plan also doesn’t account for the carbon dioxide emitted when renewable gas is burned the same way New York does. That includes a change to how the warming impact of greenhouse gasses is evaluated, with National Grid preferring a longer time horizon that gives less weight to the impact of methane - the molecule they want to continue delivering to customers. The company said its plan can slash emissions from its system in line with New York’s emissions mandate, but the analysis appears to rest on rewriting the hard-fought climate law that New York legislators passed in 2019.
The U.K.-based utility also released a similar plan for its Massachusetts business on Tuesday. National Grid serves about 1.9 million gas customers in parts of New York City and on Long Island, plus 600,000 gas and 1.6 million electric customers upstate.
