                                PROXY STATEMENT
                              -------------------
 
    This Proxy Statement is furnished to you and other shareholders of DPL Inc.
in connection with the solicitation of proxies by its Board of Directors to be
used at the Annual Meeting of Shareholders to be held at Cedarville College, 251
S. Main Street, Cedarville, Ohio, on April 14, 1998 at 10:00 a.m. and any
adjournments thereof. At the close of business on February 16, 1998, the record
date for the Annual Meeting, DPL Inc. had outstanding 160,202,949 common shares.
Only holders of common shares on such record date are entitled to vote at the
Annual Meeting, and each such shareholder is entitled to one vote per share.
 
    All common shares represented by properly executed proxies received by the
Board of Directors pursuant to this solicitation will be voted in accordance
with the shareholder's directions specified on the proxy. If no directions have
been specified by marking the appropriate squares on the accompanying proxy
card, the shares will be voted "FOR" the proposal as listed. A shareholder
signing and returning the accompanying proxy has the power to revoke it at any
time prior to its exercise.
 
    All expenses in connection with this solicitation of proxies will be paid by
DPL Inc. Proxies will be solicited principally by mail but directors, officers,
and certain other individuals specified by DPL Inc. may personally solicit
proxies. In addition, DPL Inc. has retained Georgeson & Co., a proxy
solicitation firm, to assist in the solicitation of proxies. DPL Inc. will
reimburse custodians, nominees or other persons for their out-of-pocket expenses
in sending proxy material to beneficial owners and will pay Georgeson & Co. a
fee of approximately $12,000, plus out-of-pocket expenses.
 
    This Proxy Statement together with the accompanying proxy card were first
mailed to common shareholders on or about March 2, 1998.

                            BUSINESS OF THE MEETING
 
1.  ELECTION OF DIRECTORS
 
    The Regulations of DPL Inc. provide for the classification of Directors into
three classes, with each class being of approximately equal size and in no event
shall any class contain fewer than three directors nor more than four directors.
The term of each directorship is three years and the terms of the three classes
are staggered in a manner so that only one class is elected by the shareholders
annually. The Board is presently authorized to consist of nine directors. These
nine directors are also directors of The Dayton Power and Light Company
("DP&L"), the principal subsidiary of DPL Inc. Three directors are to be elected
this year to serve until the Annual Meeting of Shareholders in 2001 or until
their successors are duly elected and qualified.
 
    Unless specifically instructed to the contrary, the Proxy Committee named in
the enclosed form of proxy will vote all duly executed proxies "FOR" the
election of the nominees named below. Should any nominee become unable to accept
nomination or election, the Proxy Committee will vote for the election of such
other person as a director as the present directors may recommend in the place
of such nominee. The following information regarding the nominees and the other
directors continuing in office is based on information furnished by them:

    The three candidates receiving the greatest number of votes will be elected
as directors. Abstentions and broker non-votes will be treated as non-votes.
 
    Under Ohio law, if a shareholder gives written notice to the President, a
Vice President or the Secretary, not less than 48 hours before the Annual
Meeting, that such shareholder desires the voting at the election of directors
to be cumulative, and if an announcement of the giving of such notice is made
upon the convening of the meeting by or on behalf of the shareholder giving such
notice, then shareholders will be entitled to give one candidate as many votes
as the number of directors to be elected multiplied by the number of their
shares, or to distribute their votes on the same principle among two or more
candidates. In the event that directors are elected by cumulative voting and
cumulated votes represented by proxies solicited hereby are insufficient to
elect all the nominees, then the Proxy Committee will vote such proxies
cumulatively for the election of as many of such nominees as possible and in
such order as the Proxy Committee may determine.

OTHER MATTERS
 
    DPL Inc. directors, all of whom are also directors of DP&L, receive no
annual fee for their services as directors of DPL Inc. Directors of DP&L who are
not employees receive $12,000 annually for services as a director, $600 for
attendance at a Board meeting, and $500 for attendance at a
 
                                       7

committee meeting or operating session of DPL Inc. and DP&L. Members of the
Executive Committee receive $2,000 annually for services on that committee. Each
committee chairman receives an additional $1,600 annually. Directors who are not
employees of DP&L also participate in a Directors' Deferred Stock Compensation
Plan (the "Stock Plan") under which a number of shares are awarded to directors
each year. All shares awarded under the Stock Plan are transferred to a grantor
trust (the "Master Trust") maintained by DPL Inc. to secure its obligations
under various directors' and officers' deferred and incentive compensation
plans. Receipt of the shares or cash equal to the value thereof is deferred
until the participant retires as a director or until such other time as
designated by the participant and approved by the Committee. In the event of a
change of control (as defined in the Stock Plan), the authority and discretion
which is exercisable by the Compensation and Management Review Committee, will
be exercised by the trustees of the Master Trust. In April 1997, each
non-employee director was awarded 1,600 shares.
 
    DPL Inc. maintains a Deferred Compensation Plan (the "Compensation Plan")
for non-employee directors in which payment of directors' fees may be deferred.
The Compensation Plan also includes a supplementary deferred income program
which provides that DPL Inc. will match $5,000 annually of deferred directors'
fees for a maximum of ten years. Under the supplementary program, a $150,000
death benefit is provided until such director ceases to participate in the
Compensation Plan. Under the standard deferred income program directors are
entitled to receive a lump sum payment or payments in installments over a period
up to 20 years. A director may elect payment in either cash or common shares.
Participants in the supplementary program are entitled to receive deferred
payments over a ten-year period in equal installments. The Compensation Plan
provides that in the event of a change in control of DPL Inc., as defined in the
Compensation Plan, all benefits provided under the supplementary deferred income
program become immediately vested without the need for further contributions by
the participants and the discretion which, under the Compensation Plan, is
exercisable by the Chief Executive Officer of DPL Inc. will be exercised by the
trustees of the Master Trust. If the consent of the Chief Executive Officer of
DPL Inc. is obtained, individuals who have attained the age of 55 and who are no
longer directors of DPL Inc. may receive a lump sum payment of amounts credited
to them under the supplementary deferred income program.
 
    Mr. Forster has entered into an agreement with DPL Inc. and DP&L pursuant to
which Mr. Forster will serve as Chairman of the Board of DPL Inc. and DP&L and
will provide various advisory and consulting services. The term of the agreement
expires on December 31, 1999 (which term is automatically extended on December
31, 1999 and each December 31 thereafter for an additional year unless either
party gives advance notice of nonrenewal). Under the agreement, Mr. Forster
receives an annual consulting fee of $500,000 (as well as such bonuses, if any,
as may be determined by the Compensation and Management Review Committee in its
discretion) and an award opportunity of 35,000 restricted shares under the Stock
Plan. Commencing in 2000, Mr. Forster will participate in a bonus program for
individuals monitoring and managing DPL Inc.'s financial assets pursuant to
which he will have the opportunity to receive an annual bonus if there is a
positive cumulative cash return on such financial assets (after recovery of all
amounts invested plus expenses). Payments under the bonus program, if and as
earned, will continue following termination
 
                                       8

of the agreement for any reason. Mr. Forster, who retired as Chief Executive
Officer of DPL Inc. effective December 31, 1996, continues to actively perform
significant duties and functions for DPL Inc. and its subsidiaries under the
agreement.
 
                             EXECUTIVE COMPENSATION
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
    DPL Inc. has designed its executive compensation programs to create a strong
and direct link between the compensation paid to senior executives and current
and long-term level of company performance. The program also recognizes each
executive's individual contribution to that performance.
 
    There are three elements of DPL Inc.'s executive compensation program. Each
element is designed to reward different aspects of executive performance.
 
        1.  Base salary and salary increases recognize competitive pay levels,
    sustained long-term value creation and contributions by individual
    executives.
 
        2.  Annual incentives, which are awarded through the Management
    Incentive Compensation Program, reward the achievement of operational and
    strategic milestones. Actual objectives vary from year to year depending on
    Company priorities and are different for each executive. Each executive has
    three or four individual objectives which are weighted equally. The
    individual objectives for 1997 were related to maintaining competitive
    energy prices and providing superior customer service. They included
    reductions in operating expenses, outside service costs, fuel inventory
    expenses and capital expenditures, as well as improvements in plant
    productivity, customer satisfaction and earnings per share. Over half of
    each executive's annual incentive payout is determined based on their
    performance as compared to their individual objectives. The remaining
    portion of the executive's annual incentive payout is based on the executive
    group's aggregate performance on their individual objectives. For 1997,
    executives generally satisfied their individual objectives. Target incentive
    awards range from thirty to sixty percent of base salary, depending upon the
    executive's position. Executives can earn from zero to one and a half times
    the target amount.
 
        3.  DPL Inc.'s long-term stock incentive unit ("SIU") plan rewards
    longer-term financial results and total return to shareholders. The actual
    number of SIU's earned is based on return on equity as compared with the
    performance of the 75 largest electric and natural gas utilities.
 
    Compensation opportunities are positioned at the general industry median.
Over half of the target total compensation for each executive will vary with
performance. Long-term incentives are paid only when return on equity
performance exceeds electric and natural gas utility industry medians.
 
                                       9

    Similar to the other executives, the Chief Executive Officer's total
compensation potential is based on consideration of median general industry
practices. The Chief Executive Officer's annual and long-term incentive programs
are variable enough to provide actual total compensation at median general
industry levels only if DPL Inc.'s performance is in the top quartile of
electric and natural gas utilities. If DPL Inc.'s return on equity performance
is at the median of the electric and natural gas utility industry or lower, the
Chief Executive Officer's actual total compensation will be at or close to
electric and natural gas utility industry median levels.
 
    Overall, Mr. Hill exceeded his annual performance objectives for 1997. Mr.
Hill's salary was increased in 1997 based on his individual contributions and
consistent with the performance criteria used for all executives. Under the
Management Incentive Compensation Program, Mr. Hill received a bonus based
seventy-five percent on DPL Inc.'s performance and twenty-five percent on the
Committee's assessment of his individual performance. Company performance
objectives were based on equal consideration of earnings per share performance,
which objective was satisfied, and the aggregate performance of the executive
group versus their individual objectives. The Committee based its assessment of
Mr. Hill's individual performance on consideration of several factors, including
DPL Inc.'s performance versus other electric and natural gas utilities,
investment community evaluations and progress on management development and
succession planning. Mr. Hill was contingently awarded 30,500 SIU's in 1997
based on consideration of median general industry long-term incentive
opportunities and the overall competitiveness of the remainder of his
compensation package. Mr. Hill will receive these SIU's in 2001 based on the
extent by which DPL Inc.'s average return on common equity between 1998, 1999
and 2000 exceeds the median for other electric and natural gas utilities.
 
    Based on current compensation levels and the present structure of DPL Inc.'s
executive compensation programs, the Committee believes that the compensation
payable to executives will not be subject to the limitation on deductibility
imposed by the Omnibus Budget Reconciliation Act of 1993.
 
    The Committee believes that DPL Inc.'s annual and long-term incentive plan
goals have contributed to the strong stock market performance shown in the
performance chart in the next section. DPL Inc.'s total return to shareholders
between 1992 and 1997 was significantly higher than total return to shareholders
for the utility industry as a whole.

    The S&P Electric Company Index has replaced the Dow Jones Utility Index used
in prior years as a utility industry index. This change has been made due to
changes in the companies included in the Dow Jones Utility Index in 1997. DPL
Inc. believes the S&P Electric Company Index, comprised of regulated electric
and combination electric and natural gas companies, is now a more appropriate
industry index against which to compare the stock price performance of DPL Inc.

(1) Amounts in this column represent awards made under the Management Incentive
    Compensation Program. Awards are based on achievement of specific
    predetermined operating and management goals in the year indicated and paid
    in the year earned or in the following year.
 
(2) Amounts shown in this column have not been paid, but are contingent on
    performance and represent the dollar value of restricted stock incentive
    units ("SIU's") awarded to the named executive officer under the Management
    Stock Incentive Plan ("MSIP") based on the closing price of a DPL Inc.
    common share on the New York Stock Exchange -- Consolidated Transactions
    Tape on the date of award. The SIU's for 1995, 1996 and 1997 vest only to
    the
 
                                       12

    extent that the DPL Inc. average return on equity ("ROE") over a three-year
    performance period is above the RRA industry median.
 
   Depending on the performance of DPL Inc., these SIU's vest in amounts ranging
    from 0% to 100% of the target award at an ROE between 0 and 100 basis points
    above median ROE and from 100% to 150% of target award at an ROE between 100
    and 200 basis points above median ROE.
 
   No units vest if the three-year average ROE is below 10%. Amounts shown for
    1995, 1996 and 1997 reflect target awards. For each SIU which vests, a
    participant receives the cash equivalent of one DPL Inc. common share plus
    dividend equivalents from the date of award. Prior to payout at retirement,
    an individual may elect to convert a portion of vested SIU's to a cash
    equivalent and accrue interest thereon. All payouts of vested SIU's under
    the MSIP are deferred until retirement.
 
(3) Amounts in this column represent employer matching contributions on behalf
    of each named executive under the DP&L Employee Savings Plan made to the DPL
    Inc. Employee Stock Ownership Plan.
 
(4) Annual compensation shown for Mr. Forster for 1997 was paid pursuant to an
    agreement with DPL Inc. and DP&L. Long term compensation award opportunities
    shown for 1996 and 1997 represent the dollar value of restricted shares
    awarded to Mr. Forster under the Directors' Stock Plan which are subject to
    the same earning and vesting criteria generally applicable to SIU's. All
    other compensation shown for 1997 represents directors fees of $32,600 and
    the dollar value of the annual award of 1,600 shares to each non-employee
    director under the Directors' Stock Plan. See "Information Concerning the
    Board of Directors and its Committees -- Other Matters."
 
CERTAIN SEVERANCE PAY AGREEMENTS
 
    DPL Inc. entered into severance pay agreements with each of Messrs. Hill,
Koziar, and Santo and Mrs. Lansaw providing for the payment of severance
benefits in the event that the individual's employment with DPL Inc. or its
subsidiaries is terminated under specified circumstances within three years
after a change in control of DPL Inc. or DP&L (generally, defined as the
acquisition of 15% or more of the voting securities or certain mergers or other
business combinations). The agreements entered into between 1987 and 1991
require the individuals to remain with DPL Inc. throughout the period during
which any change of control is pending in order to help put in place the best
plan for the shareholders. The principal severance benefits under each agreement
include payment of the following: (i) the individual's full base salary and
accrued benefits through the date of termination and any awards for any
completed or partial period under the MICP and the individual's award for the
current period under the MICP (or for a completed period if no award for that
period has yet been determined) fixed at an amount equal to his average annual
award for the preceding three years; (ii) 300% of the sum of the individual's
annual base salary at the rate in effect on the date of termination (or, if
higher, at the rate in effect as of the time of the change in control) plus the
average amount awarded to the individual under the MICP for the three preceding
years; (iii) all
 
                                       13

awarded or earned but unpaid SIU's; and (iv) continuing medical, life, and
disability insurance. In the event any payments under these agreements are
subject to an excise tax under the Internal Revenue Code of 1986, the payments
will be adjusted so that the total payments received on an after-tax basis will
equal the amount the individual would have received without imposition of the
excise tax. The severance pay agreements are effective for one year but are
automatically renewed each year unless DPL Inc. or the participant notifies the
other one year in advance of its or his or her intent not to renew. DPL Inc. has
agreed to secure its obligations under the severance pay agreements by
transferring required payments to the Master Trust. Mr. Forster's agreement with
DPL Inc. and DP&L contains similar severance benefits provisions.

      1,400,000.............................   394,500   591,500    788,500

 
    The years of accredited service for the named executive officers are Mr.
Hill -- 28 yrs.; Mr. Koziar -- 28 yrs.; Mrs. Lansaw -- 18 yrs. and Mr. Santo --
22 yrs. Years of service under the retirement income plan are capped at 30
years, however, the retirement and supplemental plans, taken together, can
provide full benefits after 20 years of accredited service. Benefits are
computed on a straight-life annuity basis, are subject to deduction for Social
Security benefits and may be reduced by benefits payable under retirement plans
of other employers. For each year an individual retires prior to age 62,
benefits under the supplemental plan are reduced by 3% or 21% for early
retirement at age 55. Mr. Forster ceased to accrue benefits under the retirement
and supplemental plans effective as of December 31, 1996 upon his retirement as
an employee of DPL Inc. and DP&L.
