Charlottesville utility releases gas-decarbonization study; offsets, RNG and hydrogen modeled, council presses for electrification analysis

Charlottesville's director of utilities presented a gas-decarbonization study and next steps to the City Council on March 4, reviewing modeled pathways that combine energy efficiency, low-carbon fuels and carbon offsets to meet the city's greenhouse-gas reduction targets.

The study, developed with consultant Black & Veatch, evaluated customer-led measures (electrification and efficiency), low-carbon fuels that can be blended into the city's municipal gas system (renewable natural gas and hydrogen) and continued purchase of certified carbon offsets. The utility director told council the system serves about 21,050 customers (about 89% residential); roughly 55% of customers are inside the city and 45% are in Albemarle County.

Key findings and numbers - Emissions and offsets: Charlottesville Gas has an existing carbon-offset contract (executed November 2021) purchased through a broker; staff reported the program increases the average monthly bill by roughly $0.60 and that current carbon-offset purchases cost about $342,000 per year. - Leak prevention and infrastructure: Black & Veatch recommended continued leak surveys every three years (the utility already surveys business sectors annually) and continuing excess-flow-valve installation; the utility…
