Unitil Basic Service Electric Rates Change

04/25/2005

Hampton, NH - April 25, 2005: Unitil Corporation's (AMEX:UTL) Massachusetts subsidiary filed Basic Service electric rates with the Massachusetts Department of Telecommunications and Energy. If approved, the rates will take effect June 1, 2005.

A typical residential customer using 500kWh per month will see a bill increase from $75.65 to $76.25 or 0.8%. Bill impacts vary based on rate class and usage. This rate change reflects current market prices for the cost of electric energy supply.

Basic Service was established for customers who did not or could not choose a competitive supplier. It is procured through a competitive bid process and the resulting rates are passed through to customers without profit or mark up from the local distribution company. Basic Service rates change for residential and small to medium business customers every six months and every three months for large business customers.

Customers who have contracted with a Competitive Supplier are unaffected by this change.

Unitil Corporation (AMEX:UTL) at (www.unitil.com) is a public utility holding company with subsidiaries providing electric service in New Hampshire, electric and gas service in Massachusetts and energy services throughout the Northeast.
