Green Mountain Power Exceeds Reliability Standards

COLCHESTER, VT, Mar 31 (MARKET WIRE) --
Green Mountain Power's customers experienced fewer outages in 2007 than in
recent
years, exceeding standards set by Vermont regulators.

"Our customers consistently tell us that providing reliable power is the
most
important thing we do, and in 2007 we had fewer customer hours without power,
despite significant storms hitting our service territory," said Mary Powell,
senior vice president and chief operating officer. "Major investments in
tree-trimming and other system upgrades have had a direct effect on improving
system reliability."

An analysis of the causes of all the outages in Green Mountain Power's
system
during 2007 shows that outages caused by tree branches within the
rights-of-way were at the lowest point in five years. Upgrades to the system
and a fast response to the outages meant that the total amount of time
customers were out due to tree branches within the rights-of-way was well
below previous years.

Green Mountain Power had an average of 1.38 outages per customer, with an
average duration of 1.79 hours. Although utilities are allowed to exclude major
storms from these calculations, Green Mountain Power's vegetation management and
storm restoration efforts enabled the Company to restore power quickly enough
that none of the severe storms last year met the exclusion standard. Green
Mountain Power's performance was significantly better than the national average
of 2.3
hours per outage, as reported by the Edison Electric Institute.

Although trees caused the most outages in 2007, other significant causes
were
equipment failure, other weather events and animals.

The Company also met or exceeded all of its service quality standards in
2007. It answered 85 percent of calls within 20 seconds, well above the 75
percent standard as well as achieved 90 percent overall customer satisfaction.

Green Mountain Power also achieved its financial goals in 2007. Operating
revenues
were $229 million in 2007, as compared with $214 million in 2006, with net
income of $10.7 million in 2007, as compared to $10.1 million 2006.

"Financial stability is a critical component of our ability to provide
premier
service to our customers. And while we are thrilled at both our financial
and customer service performance for 2007, we strive to exceed these results in
the future so that we can provide even better service to our customers,"
said Ms. Powell.

In the interest of reporting transparently to its customers, the Company
publishes the results of its service quality standards on its website at
www.greenmountainpower.biz.
