VERMONTS TWO LARGEST UTILITIES MEET
RIGOROUS EMISSIONS REDUCTIONS GOALS

COLCHESTER/RUTLAND, VT... Central Vermont Public Service and Green Mountain Power today announced they have both
successfully reduced greenhouse gas emissions in accordance with their
commitments as members of the Chicago Climate Exchange® (CCX), a voluntary,
legally binding multi-sector market for reducing and trading greenhouse gas
emissions.

"Climate change is one of the most compelling issues
in the world today, and we are pleased with our success in reducing emissions
and in helping to change the way utilities reduce greenhouse gas emissions
through a trading market," said Chris Dutton, President and
Chief Executive Officer of Green Mountain Power.

"Our customers expect us to pay attention to the
issue of climate change," said Robert Young, President and Chief
Executive Officer of Central Vermont Public Service. "Reducing our
emissions has immediate benefits to the air we breathe, and our participation
in the Chicago Climate Exchange helps stimulate the development of new
renewable resources at the lowest cost."

Both companies pledged in 2004 to reduce greenhouse
gases four percent below a baseline of the annual average of 1998 to 2001.
Importantly, both companies intend to extend their commitment to reduce
emissions as a Phase II Member of the Chicago Climate Exchange through 2010.

Richard L. Sandor, Chairman and CEO of the Chicago
Climate Exchange told both companies, "You have complied with the most
rigorous standards for greenhouse gas emission reductions available in North
America today. I commend Green Mountain Power and Central Vermont Public
Service on this outstanding undertaking as well as your leadership in promoting
best practices in greenhouse gas emissions management and corporate
sustainability."

public and private sectors to use market-based mechanisms to account for
greenhouse gas emissions reductions. CCX enables participants to receive credit
for reductions and to buy and sell credits as a means of finding the most
