Piedmont Natural Gas Projects Lower Winter Heating Costs for 2009-2010 Season

Residential customers in Company's three-state service area could see
reductions of between 10 to 20 percent in winter bills.

CHARLOTTE, N.C., Oct. 5 /PRNewswire-FirstCall/ -- Piedmont Natural Gas (NYSE:
PNY) today announced its annual forecast of winter heating costs for customers
in North Carolina, South Carolina, and Tennessee. Piedmont's forecast
projects that its residential customers could see a reduction in their overall
winter heating costs of between 10 and 20 percent compared to last year's
winter gas heating bill. For the typical residential customer, the reductions
could result in savings of $15 to $25 per month during the winter period.

Piedmont's forecast is based on current price projections for the winter
period and assumes normal winter temperatures for the upcoming winter period.
Last year, winter temperatures across Piedmont's service area ranged from
slightly warmer than normal to as much as 7 percent colder than normal.
Because of the difference in temperatures across Piedmont's service area,
individual customer savings will vary. Colder weather than forecast during
the period could result in increased consumption of natural gas and higher
bills.

While this year's forecast clearly represents good news for customers,
particularly in light of the current economic climate, many individuals and
families will nonetheless need assistance with meeting their home energy needs
throughout the coming year. To help out, Piedmont Natural Gas introduced its
Share the Warmth Round Up Program in July and announced a corporate gift of
$100,000 to the effort. Under the Share the Warmth Roundup program,
Piedmont's customers can sign up to have their monthly natural gas bills
rounded up to the nearest dollar. The amount rounded up goes to provide
emergency energy assistance funds which are distributed through various state
and local agencies in Piedmont's three-state service area. The funds are used
to provide emergency assistance regardless of the energy source that is used
in the home or the time of year in which the need occurs, to individuals and
families within the communities Piedmont serves.

For those customers who want to learn more about Share the Warmth Round Up or
to enroll in the program, they are encouraged to visit Piedmont's website at
www.piedmontng.com and click on the Share the Warmth link. Information about
the various agencies that provide emergency energy assistance through the
Share the Warmth Round Up Program or through the Federal Low Income Home
Energy Assistance Program (LIHEAP) can also be found there. In addition to
details about the Share the Warmth Round Up Program on the Company's website,
customers will also find helpful energy conservation tips, information about
customer self-services and a Carbon Calculator that allows customers to
determine their own home's carbon footprint.
