To better serve you, we have upgraded our customer information and billing system. This upgrade replaced a 30-year-old technology with a new system that will enable us to provide more efficient, flexible and responsive service to all of our customers.

You’ll see the following changes from WMECO:

• A new 11-digit account number
• A larger 8½ x 11-sized reformatted bill
• New names for our online account services
• Some new online options for customers
