                  Vectren to enhance environmental stewardship
                      through new air quality improvements

Evansville, Ind., May 16, 2005 -- Vectren Corporation (NYSE: VVC) announced
today that its utility subsidiary, Vectren Energy Delivery of Indiana, Inc., has
filed a new multi-emission compliance plan with the Indiana Utility Regulatory
Commission (IURC). The plan will mean Vectren's electric generation fleet will
be 100 percent scrubbed for sulfur dioxide (SO2), 90 percent scrubbed for
nitrogen oxide (NOx), and will further reduce mercury to meet new mercury
reduction requirements. This level of emissions reductions will continue to make
Vectren an industry leader in its environmental stewardship efforts.

"Vectren is committed to be a leader in air quality, and today's filing should
be welcome news for residents of Southwestern Indiana," said Carl Chapman,
Vectren's executive vice president and chief operating officer. "This continues
our practice of both protecting the environment and utilizing clean coal
technology with Indiana coal."

Included in phase one of the proposed project is an expenditure of approximately
$110 million to fund the construction of a flue gas desulfurization system
(scrubber) at Warrick Unit 4 scheduled for completion by 2010 and the
installation of a fabric filter at Culley 3 scheduled to be complete by
mid-2007.

"While there may be some fine tuning of the new federal requirements, it is
prudent to proceed with a core multi-emission control strategy," Chapman said.
"In order to plan outages and maintain reliability, it is important to plan and
initiate these large construction projects well in advance of compliance
deadlines. This additional capital investment positions our plants to continue
to operate in an environmentally responsible manner."

The IURC petition includes a cost recovery mechanism to spread the cost over
multiple years to minimize customer impact. When fully implemented, this
proposal would mean an approximate 6 to 8 percent increase for a typical
residential electric customer.

On March 10, 2005, the U.S. Environmental Protection Agency (EPA) issued its
Clean Air Interstate Rule (CAIR). The new CAIR rule mandates state
implementation plan revisions in 29 states, including Indiana, requiring further
reductions of NOx and SO2 beyond those currently required in the NOx SIP Call
and Acid Rain Program. Similarly, on March 15, 2005, EPA finalized its Clean Air
Mercury Rule (CAMR). The CAMR rule establishes a market-based cap and trade
approach under which each state is assigned a mercury emission budget to be
allocated among generation units within the state. Under the new CAMR,
nationwide mercury emission will be reduced 70 percent from current levels.

By using a combination of scrubbers, fabric filters and the recently installed
selective catalytic reduction devices (SCRs), Vectren will have the best
available mercury reduction equipment in place. These projects also should help
to alleviate PM2.5 (fine particulate, dust and aerosols) non-attainment in
Southwestern Indiana.

SCRs remove NOx from the flue gas created from the combustion of coal by
electric generating facilities. Both the scrubber and fabric filter are advanced
technologies designed to reduce air emissions from existing sources fueled by
coal. In this case, the construction of a scrubber and fabric filter will allow
Vectren the continued use of these two low-cost units (Warrick 4 and Culley 3)
for baseload generation and will also ensure the continued ability of these
units to burn Indiana coal.

In addition, Vectren will retire and permanently cease operation of F.B. Culley
Unit 1 by Dec. 31, 2006. The 46 MegaWatt (MW), coal-fired generation unit
located in Warrick County, Ind., was placed in service more than 50 years ago
and is the smallest coal-fired generation unit in the Vectren fleet. The
decision to retire this unit meets EPA requirements and also will enhance the
area air quality as it operates less efficiently than the larger generating
units.

In 1992, Vectren enhanced its environmental compliance plan and constructed a
scrubber for the removal of sulfur dioxide (SO2) emissions from F.B. Culley
Units 2 and 3 required by EPA's Acid Rain Program. A.B. Brown units 1 and 2 were
both originally constructed with scrubbers.

Vectren owns and operates 1351 MW of total generating capacity. Vectren's
baseload units include the following: A.B. Brown 1, 250 (MW); A.B. Brown 2, 250
(MW); Culley 1, 46 (MW); Culley 2, 90 (MW); Culley 3, 270 (MW); Warrick 4, 150
(MW) (represents Vectren's 1/2 interest in Warrick 4 - a 300 MW unit co-owned
with Alcoa Corporation). Vectren also has 295 MW of gas-fired peaking capacity.
