Wind Energy Continues to Gain Popularity Among NYSEG and RG&E Customers 

Rochester, NY, February 7, 2007 – More and more NYSEG and RG&E customers are finding that the source of
electricity they prefer is blowin’ in the wind.

As of the end of 2006, 9,300 NYSEG customers have signed up to purchase wind-generated electricity through a
program the company began offering in August 2002 in partnership with Community Energy Inc., a leading marketer of
wind energy. The number of customers participating in the NYSEG program increased more than 200% from 2005 to
2006. These NYSEG customers are expected to use 33.3 million kilowatt-hours (kwh) of wind energy in 2007.

At RG&E nearly 3,000 customers have enrolled in the wind energy program the company began offering in April
2004. The number of customers participating in the RG&E program is also up significantly over 2005. These RG&E
customers are expected to use 19.5 million kwh of wind energy in 2007.

“The wind energy programs at NYSEG and RG&E are a natural fit with our commitment to do all that we can to
protect the environment,” said Jim Laurito, president and CEO of NYSEG and RG&E. “We are pleased to be able to offer
this environmentally-friendly, renewable-energy option to our customers and we are encouraged by their enthusiastic

Customer purchases of wind energy directly benefit the environment because they offset the need for electricity
from fossil-fueled generation. Every 100 megawatts of fossil-fueled generation displaced by renewable energy sources
lowers carbon dioxide (CO2) emissions by more than 500,000 tons, a reduction equivalent to planting 21 million trees or
taking 82,000 cars off the road. Renewable energy sources also help avoid sulfur dioxide and nitrogen oxides emissions.
