                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

                      CHIEF FINANCIAL OFFICER CERTIFICATION

I, Jerome A. Benkert, Jr., certify that:

          1.   I have reviewed this Annual Report on Form 10-K of Vectren
               Corporation;

          2.   Based on my knowledge, this report does not contain any untrue
               statement of a material fact or omit to state a material fact
               necessary to make the statements made, in light of the
               circumstances under which such statements were made, not
               misleading with respect to the period covered by this report;

          3.   Based on my knowledge, the financial statements, and other
               financial information included in this report, fairly present in
               all material respects the financial condition, results of
               operations and cash flows of the registrant as of, and for, the
               periods presented in this report;

          4.   The registrant's other certifying officer(s) and I are
               responsible for establishing and maintaining disclosure controls
               and procedures (as defined in Exchange Act Rules 13a-15(e) and
               15d-15(e)) and have:

                   (a) Designed such disclosure controls and procedures, or
                  caused such disclosure controls and procedures to be designed
                  under our supervision, to ensure that material information
                  relating to the registrant, including its consolidated
                  subsidiaries, is made known to us by others within those
                  entities, particularly during the period in which this report
                  is being prepared;

                   (b) Evaluated the effectiveness of the registrant's
                  disclosure controls and procedures and presented in this
                  report our conclusions about the effectiveness of the
                  disclosure controls and procedures, as of the end of the
                  period covered by this report based on such evaluation; and

                   (c) Disclosed in this report any change in the registrant's
                  internal control over financial reporting that occurred during
                  the registrant's most recent fiscal quarter (the registrant's
                  fourth fiscal quarter in the case of an annual report) that
                  has materially affected, or is reasonably likely to materially
                  affect, the registrant's internal control over financial
                  reporting; and

          5.   The registrant's other certifying officer and I have disclosed,
               based on our most recent evaluation of internal control over
               financial reporting, to the registrant's auditors and the audit
               committee of the registrant's board of directors (or persons
               performing the equivalent functions):

                   (a) All significant deficiencies and material weaknesses in
                  the design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrant's ability to record, process, summarize and report
                  financial information; and

                   (b) Any fraud, whether or not material, that involves
                  management or other employees who have a significant role in
                  the registrant's internal control over financial reporting.
