Watch out

  • eversource.com renders phone numbers and state programs only after a town is selected; automated fetches see placeholders. Confirm the number on the customer's bill.
  • Outage reporting online needs the account phone number or a sign-in.
  • Medical Protection needs a physician's certification.
