           Vectren North seeks approval of new natural gas base rates

Evansville, Ind. -- Vectren Energy Delivery of Indiana - North, formerly called
Indiana Gas Company, Inc., a subsidiary of Vectren Corporation (NYSE: VVC),
filed a petition today with the Indiana Utility Regulatory Commission (IURC) to
adjust its base rates and charges for its gas distribution business in a
49-county region covering central and southeastern Indiana. If the filing is
approved, Vectren North expects to increase its base rates by approximately $47
million to cover the ongoing cost of operating, maintaining and expanding the
approximately 12,000-mile distribution and storage system used to serve more
than 525,000 customers.

If approved, the typical Vectren Energy Delivery of Indiana - North (Vectren
North) residential customer that uses natural gas to heat his/her home would see
a bill increase of about 7 percent. This proposal will not impact Vectren's
customers in southwestern Indiana or west-central Ohio. Vectren North's request
will be reviewed by the IURC, and there will also be public hearings conducted
regarding the proposal.

Today's base rate filing marks the first time Vectren North has filed a request
for a base ("non-gas-costs") rate increase since 1991. Over the past 13 years,
Vectren North has efficiently managed its operations to avoid an increase for
its "non-gas costs." However, during that time frame investments made to serve
Vectren North customers have exceeded $270 million, which are not reflected in
its current base rates. Also, since 1991, the amounts paid for taxes, health
care, labor and other operating costs have increased.

The petition only addresses Vectren North's "non-gas" costs, which represent
between 25 and 30 cents of every dollar paid by customers for their gas service.
These "non-gas" costs are incurred to build, operate and maintain the pipes,
other equipment and systems that are used to deliver gas across Vectren North's
system to its customers. The remaining 70 to 75 cents of each dollar represents
the cost of the gas used by customers. That gas is purchased on the competitive
wholesale market by Vectren North on behalf of its customers, and its actions
are subject to regulatory scrutiny under the state's Gas Cost Adjustment (GCA)
procedures to ensure its purchasing actions are reasonable. Every three months,
the IURC reviews Vectren North's gas purchase costs to ensure that those costs
are reasonable. Under Indiana regulation, Vectren North is not allowed to make a
profit on the cost of gas.

The filing also includes a normal temperature adjustment (NTA) mechanism to
reduce the impact on customer bills caused by the variations in weather. With
the NTA, historic average temperatures serve as the basis for computing
customers' bills, thereby smoothing out the effects of significant temperature
fluctuations.

"It has been about 13 years since we last sought to adjust our base rates. Given
this passage of time, we need an increase to recover the costs associated with
providing our customers with safe and reliable gas service. The primary driver
is the investment of more than a quarter of a billion dollars in infrastructure
upgrades over this time period," said Bill Doty, Vectren's executive vice
president of utility operations. "A strong utility infrastructure is a critical
component to Indiana's continued economic growth. Adjusting our base rates to
reflect this investment is important to our efforts to sustain and promote the
service reliability that is critical to our customers."

The merger in early 2000 of Indiana Energy, Inc. and SIGCORP, Inc. to create
Vectren, combined with the acquisition later that same year of significant
natural gas distribution assets in west-central Ohio, has contributed to the
ability to delay the need to seek a rate increase by creating the opportunity to
spread operating costs across the companies and by providing many efficiencies
that avoid duplication of costs.
