NYSEG and RG&E, Together with Sister Company Central Maine Power, Rank High in
Business Customer Satisfaction

Rochester, NY, April 5, 2007 – NYSEG, RG&E and Central Maine Power together are among the top utilities in the eastern U.S. in business customer satisfaction, according to a recent survey by J.D. Power and Associates. The three Energy East Corporation operating utilities scored a collective 704 on a 1,000 point scale.

“The results of this survey are further evidence that our employees’ focus on providing outstanding customer service is paying off in the eyes of our customers,” said Jim Laurito, president and CEO of NYSEG and RG&E. “We believe these results are also an indicator of the value our customers place on our reliable service and the fact that we offer some of the lowest rates in New York.” Laurito said planned investments in advanced metering that will provide customers with real-time pricing information to help promote conservation and improve system operating efficiency, transmission infrastructure and the redevelopment of Russell Station in Rochester would further enhance reliability and provide environmental benefits.

The annual J.D. Power survey of utility business customers is based on interviews with representatives of more than 12,900 businesses served by the largest 55 electric utilities. Customer satisfaction is measured based on performance in six categories: power quality and reliability, customer service, company image, billing and payment, price and communication.
