Electric and gas utilities have begun notifying residential customers with unpaid and/or past-due balances that if they do not take action and contact their utility to enroll in a payment plan, they are at risk of having their gas services terminated on Thursday, May 2, 2024. If your household has received a notification from your utility company, please contact them directly to set up a payment plan to keep your services on. These plans charge no interest, and all customers qualify at least once for one or more of these plans. After engaging with utility providers, customers may also contact PURA’s customer affairs unit for specific questions regarding payment arrangements. View eligibility, utility contact information
