FOR IMMEDIATE RELEASE

April 26, 2005


                               Vectren Corporation
                       Reports First Quarter 2005 Increase


Evansville,  Indiana - Vectren Corporation  (NYSE:VVC) today reported net income
for the three months ended March 31, 2005 of $56.1 million,  or $0.74 per share,
compared  to net  income of $54.8  million,  or $0.73 per  share,  for the three
months ended March 31, 2004.  Weather for the quarter was 7 percent  warmer than
normal and 3 percent warmer than the prior period.


Company Highlights

     o    Increased utility earnings during the first quarter of 2005
     o    Increased results from Coal Mining operations during the first quarter
          of 2005
     o    Implemented new Vectren Ohio gas rates in April 2005
     o    Affirmed 2005 earnings guidance

Said Niel C. Ellerbrook,  Chairman, President and CEO, "We are very pleased with
our first quarter results,  despite the warmer than normal weather impacting our
heat sensitive throughput.  In the last nine months we have implemented new base
rates for all three of our gas  jurisdictions  and  continue  to  recover  costs
associated with our power generation environmental compliance expenditures.  The
nonregulated  group also performed well during the quarter,  especially our coal
mining group,  which achieved  increased  production  levels.  We continue to be
confident in our previously disclosed 2005 earnings guidance."


2005 Earnings Guidance

The company  affirmed  that fiscal 2005 earnings are expected to be in the range
of $1.70 to $1.90 per  share.  The  targeted  range is  subject  to the  factors
discussed under "Forward  Looking  Statements"  including normal weather for the
balance of the year, stable economic  conditions,  and continued growth from the
company's nonregulated businesses.


Utility Group

Utility  Group  earnings were $48.1 million for the three months ended March 31,
2005,  compared to $44.7 million in the prior year. The $3.4 million increase in
the Utility Group earnings is due to the implementation of new gas base rates in
the company's Indiana service  territories,  higher electric revenues associated
with recovery of pollution control  investments and increased wholesale electric
margins.  Gas base rate increases added margin of $7.9 million,  or $4.7 million
after tax. These increases were partially offset by the impact of warmer weather
on  customer   usage  during  this  high   consumption   quarter  and  increased
depreciation  expense and income  taxes.  For the quarter  ended March 31, 2005,
heating weather 7 percent warmer than normal and 3 percent warmer than the prior
year reduced  first  quarter 2005  margins by an  estimated  $4.8 million  ($2.9
million  after tax) and by an estimated  $3.0 million  ($1.7  million after tax)
when compared to the same period last year.

Gas  utility  margins  for the three  months  ended  March 31,  2005 were $145.8
million, an increase of $6.3 million,  or 4 percent,  compared to the prior year
period.  The rate case  orders  implemented  in the  second  half of 2004  added
revenues of $7.9  million.  This  increase in  revenues  reflects  new gas rates
designed  to recover the  majority of the  authorized  increase  evenly  through
higher customer  charges and non-weather  sensitive usage rates. It is estimated
that the impact of weather  decreased  margin $2.6 million  compared to the same
period last year and was the primary  contributor to decreased  throughput.  The
remaining change is primarily  attributable to expense recovery pursuant to Ohio
regulatory trackers.

Electric  retail and firm wholesale  margins were $56.5 million,  an increase of
$2.0 million when  compared to 2004.  Margin  increased  $2.6 million due to the
increase in retail  electric  rates  related to the  recovery  of  environmental
compliance  expenditures and related operating  expenses.  The effects of warmer
weather  partially  offset these increases by $0.4 million  compared to the same
period last year.

Electric wholesale margin primarily results from asset  optimization  activities
derived from  generation  capacity in excess of that needed to serve native load
and firm  wholesale  customers.  Net wholesale  margins  increased  $2.0 million
compared to 2004 due to an increase in available  capacity.  The availability of
excess  capacity was impacted in 2004 by scheduled  outages of owned  generation
related to the installation of environmental compliance equipment.

Other operating expenses decreased $0.5 million for the three months ended March
31, 2005 compared to the same period in 2004.  The decrease was primarily due to
$1.1 million in lower NOx operating expenses, offset somewhat by increased costs
for scrubber chemicals, gasoline and other costs.

Depreciation  expense for the three months ended March 31, 2005  increased  $3.8
million  compared to 2004.  Installation of environmental  compliance  equipment
accounted  for $1.4 million of the increase.  In addition,  the first quarter of
2004 was $1.8 million lower due to a one-time  adjustment of depreciation  rates
and amortization of regulatory assets.

Income  taxes for three  months  ended March 31, 2005  increased  $4.2  million,
compared to 2004, primarily attributable to higher pre-tax income.


Vectren Energy Delivery of Ohio Rate Settlement Implemented

On April 13,  2005,  the Public  Utilities  Commission  of Ohio (PUCO)  approved
Vectren Energy  Delivery of Ohio's (VEDO) base rate increase for its natural gas
distribution business. The PUCO's order provides for a $15.7 million increase in
VEDO's base  distribution  rates. As reported  previously,  new natural gas base
rate  increases  were  implemented  for Vectren  Energy  Delivery's  two Indiana
service territories on July 1, 2004 and on December 1, 2004. In all three cases,
the new rates  implemented were designed to help mitigate the effects of extreme
weather with a significant portion of the rate increases achieved through higher
customer  charges and higher  non-weather  sensitive usage rates. As such, it is
expected that the allowed  increases will generally be realized  evenly over the
course of a year.


Nonregulated Group (all amounts following in this section are after tax)

Nonregulated  Group  earnings were $8.9 million for the three months ended March
31, 2005, as compared to $10.6 million in the prior year. The company's  primary
nonregulated  business groups,  Energy Marketing and Services,  Coal Mining, and
Utility Infrastructure  Services contributed $9.4 million to 2005 earnings, down
slightly  from the $10.0 million  contributed  in 2004.  The slight  decrease is
attributable  to lower earnings from gas marketing and  performance  contracting
operations,  partially offset by increased earnings from mining operations.

The 2004 contribution  from Other Businesses  reflects an after tax gain of $5.3
million  recognized  on the  sale of an  investment  held by  Haddington  Energy
Partners  which was largely offset by a $4.5 million after tax charge related to
the write down of the company's broadband investments.


Energy Marketing and Services

Energy  Marketing  and  Services is  comprised of the  company's  gas  marketing
operations, performance contracting operations and retail gas supply operations.

Net income  generated by Energy  Marketing  and  Services for the quarter  ended
March 31,  2005,  was $6.0  million  compared to $7.0  million in 2004.  In both
periods presented, gas marketing operations, performed through ProLiance Energy,
provided the primary  earnings  contribution,  totaling  $6.4 million in 2005, a
slight  decrease  from the $6.9 million  contributed  in 2004.  This decrease is
attributable  to  pre-verdict  legal fees  associated  with  litigation  between
ProLiance  and the  City of  Huntsville,  Alabama  (Huntsville  Utilities).  The
remaining  decrease in earnings  contribution  is primarily  attributable to the
timing of performance contracting operations.  For the quarter, Vectren Source's
retail gas supply  operations  earned $0.8 million,  compared to $0.6 million in
the prior period. Source's earnings contribution was also significantly impacted
by warmer than normal weather.


Coal Mining

The Coal Mining Group mines and sells coal to the Company's  utility  operations
and to other third parties  through its wholly owned  subsidiary  Vectren Fuels,
Inc.  (Fuels).  The Coal Mining  Group also  generates  IRS Code  Section 29 tax
credits resulting from the production of coal-based  synthetic fuels through its
8.3% ownership interest in Pace Carbon Synfuels,  LP (Pace Carbon). In addition,
Fuels receives  synfuel-related  fees from synfuel  producers  unrelated to Pace
Carbon for a portion of its coal production.

Coal  Mining net income for the three  months  ended  March 31,  2005,  was $4.4
million,  compared to $3.6 million in 2004.  Earnings from the Mining operations
were $1.3 million in 2005,  compared to $0.7 million in 2004.  The  contribution
from Mining operations  increased despite rising commodity costs,  primarily due
to greater  production and higher revenue per ton.  Synfuel-related  results for
the quarter, which include earnings from Pace Carbon and synfuel processing fees
earned  by  Fuels,   increased  $0.2  million.  This  increase  reflects  higher
production  of  synthetic  fuel  produced  by Pace  Carbon as the  result of the
relocation of a previously underperforming plant.


Utility Infrastructure Services

Utility Infrastructure Services provides underground  construction and repair to
gas, water,  electric and  telecommunications  companies  primarily  through its
investment  in  Reliant  Services,  LLC  (Reliant)  and  Reliant's  100  percent
ownership in Miller Pipeline.  Reliant is a 50 percent owned strategic  alliance
and is accounted for using the equity method of accounting.

For the three  months  ended March 31, 2005,  Utility  Infrastructure  Services'
operated at a seasonal loss of $1.0 million,  compared to a loss of $0.6 million
in 2004


Broadband and Other Businesses

Broadband  invests  in  communication   services,   such  as  cable  television,
high-speed  internet,  and advanced local and long distance phone services.  The
Other Businesses Group includes a variety of operations and investments.

For the three months ended March 31, 2005, other  businesses  reported a loss of
$(0.5)  million,  compared to earnings of $0.6 million in 2004.  The decrease is
primarily  due to the net  contribution  in 2004  from an after tax gain of $5.3
million  recognized  on the  sale of an  investment  held by  Haddington  Energy
Partners, which was largely offset by a $4.5 million after tax charge related to
the write down of the Company's broadband investments.


Corporate

Contributions  to various  community and civic  organizations  and corporate and
other expenses in the first quarter 2005 were $0.9 million after tax.
