BOSTON — The Massachusetts Department of Public Utilities (DPU) today announced it has approved additional reductions in gas supply rates for Eversource Gas of Massachusetts and Boston Gas Company d/b/a National Grid gas customers. On average, the decreases will result in a monthly bill decrease of about 10 percent for a typical residential heating customer. Eversource serves approximately 300,000 customers, and National Grid serves approximately 950,000 customers. 
 
Beginning on March 1, 2023, customers served by the companies can expect lower gas supply rates, which last until May 1. National Grid and Eversource Gas of Massachusetts previously lowered their gas supply rates effective February 1, 2023, and December 1, 2022, respectively. The further decrease in rates is attributable to updated forecasts in customer usage and the market-based price of natural gas over the course of the winter period.
