Hampton, NH (February 12, 2007) Unitil Corporation (AMEX:UTL) today announced that it received the AMI Project of the Year award at the DistribuTECH 2007 Conference & Exposition in San Diego, California, in recognition of its Advanced Metering Infrastructure (AMI) project.

Unitil's AMI project will be completed by summer 2007 and will provide automated, two-way meter reading capability for all of Unitil's nearly 115,000 customers including both gas and electric accounts. The project incorporates power-line-carrier information transmission technology developed by Hunt Technologies, and utilizes meter installation services from Honeywell.

"Unitil won our AMI Project of the Year Award because of the success of its AMI project, its unique nature, and the obstacles Unitil had to overcome. To deploy a full two-way gas and electric AMI system over a multi-state, multi-service territory with such a diverse terrain -- and to do it in the amount of time Unitil is doing it -- was, in our opinion, very impressive", said Steve Brown, editor of Utility Automation & Engineering T&D Magazine.

"The integration of people and technology is the most challenging task in managing a business in the world today," said Bob Schoenberger, Chairman and Chief Executive Officer of Unitil. "Doing it right requires strong cross-functional teams with the talent, commitment and resources to get the job done."

The AMI Project of the Year Award was accepted on Unitil's behalf by Raymond Morrissey, Vice President of Information Systems, Glenn Appleton, Director of Metering and Service and Michael Deschambeault, AMI Project Manager.

As of the end of January, 2007, the AMI project in Unitil's Massachusetts service area is 95% complete. Customer data is being collected, and billing information compiled, automatically, and remotely, for nearly 40,000 gas and electric customer accounts. In New Hampshire, meter installations are well underway and the entire system should be installed, tested and providing data for billing purposes by summer 2007.
