CL&P Brings New Technology to Southern New England to Strengthen Transmission Lines

BERLIN, Connecticut, January 22, 2007 — The Connecticut Light and Power Company (CL&P), part of the Northeast Utilities System (NYSE: NU), is strengthening high-voltage transmission lines using a splice technology and maintenance method that is new to southern New England. The state-of-the-art process enhances the CL&P transmission system to provide safe and reliable electricity for customers.

This work is being conducted on some 100 miles of 345-kilovolt lines in Connecticut and western Massachusetts. Highly-trained crews are making these upgrades while the lines are energized so that customers are not inconvenienced. The work will not interrupt electric service to homes or businesses.

The upgrade calls for replacing hundreds of connectors, installed more than 40 years ago, with new connectors. The work creates a sound that is similar to the final aerial burst of a commercial fireworks display. The process is safe and has been approved by federal, state and local officials.

The upgrades began in the fall of 2006. This month, CL&P will be performing this work in the following towns: Middletown, Middlefield, Watertown, Thomaston, Plymouth, Waterbury, Wolcott and Southington.
