                         SOLICITATION AND VOTING RIGHTS
 
     The accompanying proxy is solicited by the Board of Directors of Powell
Industries, Inc., a Nevada corporation (the "Company"), for use at the Annual
Meeting of Stockholders of the Company to be held on Friday, March 13, 1998 at
11:00 a.m., Houston time, at the Hobby Airport Hilton, 8181 Airport Boulevard,
in Houston, Texas, or at any adjournment thereof.
 
     This Proxy Statement and proxy and the accompanying Notice of Annual
Meeting, Summary Annual Report to Stockholders, and Form 10-K for the year ended
October 31, 1997, including consolidated financial statements, will be mailed to
stockholders on or about January 30, 1998. The cost of soliciting proxies in the
enclosed form will be borne by the Company. The Board of Directors of the
Company has fixed January 14, 1998, as the record date for determination of
stockholders entitled to receive notice of and to vote at the Annual Meeting.
There are 10,644,205 shares of the Company's Common Stock, par value $.01 per
share ("Common Stock"), outstanding and entitled to vote. Each holder of Common
Stock will be entitled to one vote for each share owned.
 
     The presence, in person or by proxy, of the holders of a majority of the
outstanding shares of Common Stock of the Company is necessary to constitute a
quorum at the meeting. The three persons receiving the greatest number of votes
cast at the meeting to fill the directorships with terms to expire in 2001 will
be elected as directors of the Company, class of 2001. Thus, abstentions and
broker non-votes will have no effect on the election of directors. Regarding
other matters, under Nevada law generally the vote of stockholders who hold at
least a majority of the voting power present at a meeting at which a quorum is
present is the act of the stockholders. Accordingly, abstentions and broker
non-votes will have the effect of negative votes with respect to any such other
matters.
 
     The shares represented by each valid proxy received by the Company on the
form solicited by the Board of Directors will be voted in accordance with
instructions specified on the proxy. Under Nevada law, a stockholder giving a
duly executed proxy may revoke it before it is exercised only by filing with or
transmitting to the Secretary of the Company an instrument or transmission
revoking it, or a duly executed proxy bearing a later date.

                             ELECTION OF DIRECTORS
 
     The terms of three directors expire in 1998 under the bylaws of the
Company. The terms of the remaining directors continue after the Annual Meeting.
The Board of Directors has nominated Thomas W. Powell, Joseph L. Becherer and
Lawrence R. Tanner for election as directors with terms to expire in 2001. Mr.
Powell and Mr. Tanner currently serve as directors of the Company, each with a
term expiring in 1998. Mr. Becherer was elected by the Board of Directors on
November 7, 1997 to replace Elbert D. Stewart, Jr., who had resigned on November
6, 1997 upon reaching retirement age for directors, to complete Mr. Stewart's
term which expires in 1998. Mr. Tanner has also reached retirement age, but the
Board has been unable to locate a suitable successor to nominate and accordingly
has requested that Mr. Tanner continue to serve until the Board can secure a
successor. Although the Board of Directors does not contemplate that any of the
nominees will be unable to serve, if such a situation arises prior to the Annual
Meeting, the persons named in the enclosed form of proxy will vote in accordance
with their best judgment for a substitute nominee.
 
     The following table sets forth for each nominee and for each director whose
term of office continues after the Annual Meeting, his name, age, principal
occupation and employment for the past five years, offices held with the
Company, the date he first became a director, and the date of expiration of his

     Only those directors who are not employees of the Company or any of its
subsidiaries or affiliates are entitled to receive a fee, plus reimbursement of
out-of-pocket expenses, for their services as directors. Under the Company's
standard arrangement for compensation of directors, outside directors receive a
quarterly retainer of $2,000 and a fee of $2,000 for each board meeting
attended. Members of a committee other than the chairman receive a fee of $600
for attending each committee meeting. Committee chairmen receive $1,000 for
attending each committee meeting.
 
     In 1993, the Company adopted the Powell Industries, Inc. Directors' Fee
Program which permits directors to defer receipt of the directors' fees to which
they would otherwise be entitled and to have such deferred fees allocated to a
shadow account as if they were invested in Common Stock of the Company on the
date the fees were payable. Then upon expiration of the deferral period or the
retirement or death of the director, payment will be made in the form of shares
of Common Stock equal to the number of shares in his shadow account (plus any
distributions on the Common Stock that were credited to the shadow account).
 
     During the Company's last fiscal year, the Company purchased approximately

policies and reporting practices of the Company and its subsidiaries and the
sufficiency of the audits of all Company activities. It is the Board's agent in
ensuring the integrity of financial reports of the Company and its subsidiaries,
and the adequacy of disclosures to shareholders. The Audit Committee is the
focal point for communication between other directors, the independent auditors,
internal auditor and management as their duties relate to financial accounting,
reporting, and controls.
 
     The Board of Directors also has a standing Compensation Committee which met
2 times during the last fiscal year. The Compensation Committee consists of Mr.
Sykora, Mrs. Powell, and Mr. Wolny. During the year it consults with management

(1) Such options become exercisable at the rate of 20% per year on each of the
    first five anniversaries of June 25, 1997, the date of grant, provided that
    the officer remains employed by the Company or one of its subsidiaries.
    However, upon a change in control of the Company (as defined in the 1992
    Powell Industries, Inc. Stock Option Plan and the Non-Qualified Stock Option
    and Stock Award Agreements thereunder), all previously unexercised options
    will become immediately exercisable. The officer will additionally be
    entitled to receive one share of restricted Common Stock of the Company for
    each five shares of stock acquired through exercise of an option. Such
    restricted stock shall be forfeited if the officer disposes of the stock
    acquired through exercise of the option within five years, or if during such
    five-year period he voluntarily leaves the Company and its subsidiaries
    other than due to retirement or is terminated for cause.
 
(2) The exercise price may be paid by check or in shares of the Common Stock of
    the Company.
 
(3) An officer's options shall terminate earlier upon severance of employment
    with the Company and its subsidiaries, except that (i) if an officer shall
    retire at or after age 62, his options that are then currently exercisable
    shall continue until the expiration date; (ii) if an officer is terminated
    without cause or is terminated in connection with the sale of an operating
    division or unit, his options that are then currently exercisable shall
    continue until the earlier of the expiration date or 90 days after the date
    of the officer's termination; (iii) if an officer shall retire or terminate
    service for disability, or dies while in the employ of the Company or its
    subsidiary, his options shall become 100% exercisable and may be exercised
    until the earlier of the expiration date or one year following the date of
    retirement or termination for disability or death; and (iv) if an officer
    has retired for age or disability or was severed for disability and later
    dies

     Each of the named executive officers is covered by the Company's Executive
Severance Protection Plan, which provides severance pay and other specified
benefits upon termination of employment other than for cause (as defined in the
Plan) within three years of a change in control of the Company. The benefits
payable in such event (grossed up for taxes) are (1) three times the officer's
current annual base salary, plus (2) three times the maximum incentive
opportunity for the officer under the Company's then current Incentive
Compensation Plan, plus (3) continuation of medical, dental, and life insurance
benefits for three years or until the officer is covered under another plan,
whichever is earlier.
 
     Thomas W. Powell is covered by the Company's Executive Benefit Plan.
Pursuant to Mr. Powell's Executive Benefit Agreement executed under such Plan,
he is entitled to the following payments: (1) if he should die while in active
employment with the Company, a lump sum benefit of $630,000 payable to his
designated beneficiary; (2) upon normal retirement on or after age 65 and the
completion of at least ten years of continuous employment, salary continuation
payments of $150,000 per year for five years and then $75,000 per year for ten
years; (3) upon termination of employment prior to qualifying for normal
retirement but after attaining age 55 and the completion of at least ten years
of continuous employment with the Company, the salary continuation payments
payable upon normal retirement, reduced by  1/2% for each month prior to age 65
that employment is terminated, commencing on the later of the date of retirement
or attainment of age 60; and (4) upon a sale of all or substantially all of the
property and assets of the Company other than in the usual course of its
business, or a merger of the Company wherein the Company is not the surviving
corporation, and within two years thereafter Mr. Powell's employment with the
Company is terminated or he resigns following a change of his position to one of
less responsibility, Mr. Powell would be entitled to receive salary continuation
payments of $150,000 per year for five years and then $75,000 per year for ten
years. If Mr. Powell entered into competition with the Company following
termination or retirement described in (3) above, he would (a) forfeit all
further payments if the competition occurred within 36 months following
termination, or (b) not be entitled to any further payments until age 60, if the
competition occurred after 36 months following termination.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee (the "Committee") of your Board of Directors is
pleased to present its annual report to shareholders on executive compensation.
This report summarizes the responsibilities of the Committee, the compensation
policy and objectives that guide the development and administration of the
executive compensation program, each component of the program, and the basis on
which the compensation for the Chief Executive Officer, corporate officers and
other key executives was determined for the fiscal year ended October 31, 1997.
 
     The Committee's responsibilities are to oversee the development and
administration of the compensation program for corporate officers and subsidiary
presidents, and administer the executive incentive and stock option plans. The
Committee met 2 times during the year.
 
EXECUTIVE COMPENSATION PHILOSOPHY
 
     The objective of the executive compensation program is to create strong
financial incentive for corporate officers and managers and subsidiary
executives to increase profits and grow revenues. The following objectives guide
the Committee in its deliberations:
 
     - Provide a competitive compensation program that enables the Company to
       attract and retain key executives and Board members.
 
     - Assure a strong relationship between the performance results of the
       Company or subsidiary and the total compensation received.
 
     - Balance both annual and longer performance objectives of the Company.
 
     - Encourage executives to acquire and retain meaningful levels of Common
       Stock of the Company.
 
     - Work closely with the Chief Executive Officer to assure that the
compensation program supports the management style and culture of the Company.
 
     In addition to normal employee benefits, the executive total compensation
program includes base salary, annual cash incentive compensation, and longer
term stock based grants and awards.
 
     Primary market comparisons are made to a broad group of manufacturing
companies, adjusted for size and job responsibilities. This group is broader
than the published industry index of companies included in the cumulative total
return performance graph presented elsewhere in this Proxy Statement and is used
because it is more representative of the executive market in which the Company
competes for talent and provides a consistent and stable market reference from
year to year. Data sources include national survey databases, proxy statement
disclosures, and general trend data provided by consultants.
 
     Variable incentives, both annual and longer term, are important components
of the program and are used to link pay and performance results. Variable
incentive awards and performance standards are calibrated such that total
compensation will generally approximate the market 50th percentile when Company
performance results are at target levels, and will exceed the 50th percentile
when performance exceeds targets.
 
     The Internal Revenue Code (Section 162(m)) impose a $1,000,000 limit, with
certain exceptions, on the deductibility of compensation paid to each of the
five highest paid executives. In particular, compensation that is determined to
be "performance based" is exempt from this limitation. To be "performance
based," incentive payments must use predetermined objective standards, limit the
use of discretion in making awards, and be certified by the Compensation
Committee made up of "outside directors." While the Committee
 
                                       12
   15
 
believes that the use of discretion is appropriate in specific circumstances, it
believes that the annual incentive compensation and longer term stock plans
comply with the provisions of Section 162(m) as "performance based". It is not
anticipated that any executive will receive compensation in excess of this limit
during fiscal year 1998. The Committee will continue to monitor this situation
and will take appropriate action if it is warranted in the future.
 
     Following is a discussion of each of the principal components of the
executive total compensation program.
 
  Base Salary
 
     The base salary program targets the median of the primary comparison group
for corporate officers and managers. Since subsidiary presidents generally have
a higher incentive opportunity relative to comparable positions in the market,
base salaries for subsidiary presidents are targeted somewhat below the market
median. Each executive is reviewed individually on an annual basis. Salary
adjustments are based on the individual's experience and background, performance
during the prior year, the general movement of salaries in the marketplace, and
the Company's financial position. Due to these factors, an executive's base
salary may be above or below the control point at any point in time.
 
  Annual Incentive Compensation
 
     The Company administers an annual incentive plan for its corporate officers
and managers, and subsidiary presidents and selected subsidiary managers. The
goal of the plan is to reward participants in proportion to the performance of
the Company and/or the subsidiary for which they have direct responsibility, and
their individual contributions to the Company's success.
 
     Subsidiary participants are measured on pre-tax return on sales and revenue
growth for the subsidiary. Return on sales is weighted 70% and revenue growth is
weighted 30% in determining the actual incentive awards. Historical performance
results, and budgeted profit levels and expected revenue growth for the plan
year are considered in setting the performance standards for each subsidiary.
 
     For fiscal year 1997, corporate participants were measured on the Company's
earnings per share and revenue growth. Earnings per share were weighted 70%, and
revenue growth 30%.
 
     If budgeted performance is achieved, the resulting incentive awards, in
combination with base salary, are targeted at the 50th percentile of the market.
If performance is above target, cash compensation will be above the market
median. Due to corporate performance above targeted levels in fiscal 1997,
executive total cash compensation levels for fiscal year 1997 were above
average, which is consistent with this strategy.
 
  Stock Based Compensation
 
     Stock ownership is encouraged through the use of a stock plan that provides
for the grant of stock options and stock awards. Stock option grants are made on
a periodic basis (typically every other year) and are based on competitive
multiples of base salary. Senior executives typically have a higher multiple
and, as a result, have a greater portion of their total compensation linked to
the longer term success of the Company. In determining the appropriate grant
multiples, the Company targets the market median among publicly held
manufacturing companies of similar size. To encourage stock retention,
participants who retain the shares obtained through the exercise of an option
receive a restricted stock award equal to one additional restricted share for
every five option shares retained for five years from the date they were
acquired. During the year, the
 
                                       13
   16
 
Committee approved the grant of options for 250,500 shares, constituting
approximately 2.35% of the total shares outstanding.
 
COMPENSATION OF THE CHIEF EXECUTIVE OFFICER
 
     The Chief Executive Officer, Mr. Thomas W. Powell, participates in the
executive compensation program described in this report.
 
     In establishing the total compensation program for Mr. Powell, the
Committee assessed the pay levels for CEOs in similar companies in the
manufacturing industry and the profit performance of the Company. During fiscal
year 1997, Mr. Powell received stock options for 30,000 shares with an option
price of $15.81 per share (fair market value on the date of grant). These
options become exercisable over five years and have a term of seven years.
