CL&P’s Bethel-Norwalk Transmission Line Delivers Needed Power and Customer Savings

BERLIN, Connecticut, October 24, 2007 — The Connecticut Light and Power Company (CL&P), part of the Northeast Utilities System (NYSE: NU), today announced that the new Bethel-Norwalk (B-N) 345-kilovolt (kV) electric transmission line has saved customers millions of dollars in federally mandated charges since it was energized in October 2006.

Congestion savings from November 2006 through September 2007 are over $130 million. For 2007, congestion costs have been cut by more than 60% in Connecticut, down from about $200 million for the period January through September 2006 to about $80 million over the same period of this year.

The impact of B-N on an average bill for a CL&P customer using 700 kilowatt-hours a month is notable: the project cost is about $0.60 per month, but the estimated congestion savings is $2.69 per month, a net savings of about $25 a year.

“NU’s construction projects are part of the most dramatic reliability improvements in New England’s transmission infrastructure in 25 years,” said Charles W. Shivery, NU chairman, president and chief executive officer. “The Bethel-Norwalk line has already saved customers more than $130 million by reducing transmission congestion and related costs. This project is good for our customers and good for the state’s economy.

The new transmission line not only improves the reliability of the region’s power supply and is producing significant congestion savings, it’s also added tremendous value to local grand lists. This year, CL&P tax payments to the four project towns increased by more than $5 million. For example, CL&P tax payments to the town of Bethel soared from $386,000 in 2006 to $2.6 million this year.

One of the largest transmission projects recently completed in the country, the B-N project was completed ahead of schedule by two months and came in under budget by more than $15 million. The B-N project uses state-of-the-art technology such as a gas-insulated system substation that reduced land space to meet site limitations. The company is also leading the industry in its application of underground transmission by installing the longest length of 345-kV solid dielectric cable in the United States.

“The savings realized with Bethel-Norwalk bodes well for transmission infrastructure upgrades already in the pipeline and new ones to come,” said Shivery. The B-N project is the first of four major initiatives in southwest Connecticut that will resolve long-standing reliability challenges and will make our regional transmission grid more secure and efficient. In Connecticut, work is under way on the Middletown-Norwalk project, the Glenbrook Cables project and the Long Island Replacement Cable, which further extend the benefits of the 345-kV bulk power system into southwest Connecticut.
