                  (Names and addresses of agents for service)


      American Electric Power Company,  Inc. ("AEP"), a New York corporation and
a registered  holding  company under the Public Utility  Holding  Company Act of
1935,  as amended  (the "1935  Act"),  Central  and South  West  Corporation,  a
Delaware  corporation  ("CSW"),  a registered holding company under the 1935 Act
and a wholly-owned  subsidiary of AEP, and CSW Energy, Inc. ("Energy"),  a Texas
corporation,  an  indirect  subsidiary  of AEP  and a  wholly-owned  non-utility
subsidiary of CSW, hereby amend the Form U-1 Application-Declaration in File No.
70-8205 and restate the  Application-Declaration  in the following respects.  In
all other respects the  Application-Declaration  as previously filed and amended
will remain the same.

ITEM 1.  DESCRIPTION OF PROPOSED TRANSACTIONS

      Pursuant  to an order of the  Commission  dated  August 6, 1993  (HCAR No.
25866) (the "1993 Order") with respect to the  Application-Declaration,  CSW and
Energy obtained  authorization,  among other things,  from time to time to issue
letters of  credit,  bid bonds or  guarantees  (collectively,  "Guarantees")  in
connection   with  the  development  of  qualifying   cogeneration   facilities,
qualifying small power production  facilities and independent  power facilities,
including  exempt  wholesale  generators as defined in Section 32(e) of the 1935
Act  (collectively,  "Facilities")  in an  aggregate  amount  not to exceed  $50
million.  This Guarantee authority was increased from $50 million to $75 million
by order of the  Commission  dated November 28, 1995 (HCAR No. 26416) (the "1995
Order") and expires  December  31,  2000.  The 1993 Order and the 1995 Order are
sometimes collectively referred to herein as "the Orders".

      CSW became a wholly owned subsidiary of AEP on June 15, 2000,  pursuant to
an order of the Commission dated June 14, 2000 (HCAR No. 27186).

      AEP, CSW and Energy hereby request that the  Commission  authorize (a) the
aggregate amount of Guarantees that may from time to time be issued to equal $75
million;  (b) extension of the authorization  under the  Application-Declaration
until March 31,  2006;  and (c) AEP to issue  Guarantees  in addition to CSW and
Energy.  Applicants do not seek to widen such authority,  which will necessarily
remain limited to the Orders and this Amendment.

      This extended  authority (and its vesting in AEP) is needed to enable AEP,
CSW,  Energy and such  subsidiaries to continue and to diversify the development
program with respect to Facilities in accordance with the Orders. CSW and Energy
have issued  Guarantees  in  connection  with  several  Facilities  which are in
various stages of development.  Taken together, these Facilities are expected to
provide substantial revenue to Energy and,  indirectly,  to AEP over the life of
these Facilities.

      Because of the long lead time and  significant  development  expenses that
are required to develop Facilities, however, the success of Energy's development
program depends on a number of factors,  including (1)  diversification  of such
development  efforts over as many Facilities as possible to reduce the effect of
any  particular  Facility  on such  program;  (2)  Energy's  financial  ability,
pursuant  to  Commission  authority,  to take  advantage  of future  development
opportunities  as they  arise  on a  timely  basis;  and  (3)  AEP's  and  CSW's
willingness to guarantee the obligations of AEP's subsidiaries in the short term
in order to create long term profits from developing,  constructing,  owning and
operating Facilities, as contemplated by the Orders.

      The financing and  construction  of some of these  Facilities have already
been  specifically  approved  by  the  Commission;  others  are  in  preliminary
evaluation,  predevelopment,  development  and  structuring  stages.  For  these
reasons,  the Applicants  hereby seek to extend the $75 million aggregate amount
of Guarantees from time to time that may be issued and to authorize AEP to issue
Guarantees pursuant to this Amendment.  By increasing economies of scale through
a diversified Facility investment program, permitting the optimal utilization of
AEP's, CSW's and Energy's development  experience and reducing the impact of the
risk of  failure of any  particular  project on the AEP  system,  this  expanded
authority will benefit shareholders, ratepayers and the general public.


ITEM 2.  FEES, COMMISSIONS and EXPENSES

      The fees,  commissions and expenses incurred or expected to be incurred in
connection with the transactions  proposed in this Post-Effective  Amendment are
estimated not to exceed $2,000, including fees and expenses to be billed at cost
by American Electric Power Service Corporation.


ITEM 3.  APPLICABLE STATUTORY PROVISIONS

      Sections  6,  7,  9,  10 and 12 and  Rule 45  under  the  1935  Act may be
applicable with respect to the proposed activities.

      To the  extent  that  the  proposed  transactions  are  considered  by the
Commission to require authorization,  approval or exemption under any section of
the  1935  Act or  provision  of the  rules  or  regulations  other  than  those
specifically  referred to herein,  request for such  authorization,  approval or
exemption is hereby made.

                             Compliance with Rule 54

      Rule  54  provides  that  in  determining   whether  to  approve   certain
transactions other than those involving an exempt wholesale generator ("EWG") or
a foreign utility company  ("FUCO"),  as defined in the 1935 Act, the Commission
will not consider the effect of the capitalization or earnings of any subsidiary
which is an EWG or FUCO if Rule 53(a), (b) and (c) are satisfied. All applicable
conditions  of Rule 53(a) are currently  satisfied  except for clause (1). As of
June 30, 2000, AEP,  through its  subsidiaries,  had an aggregate  investment in
EWGs and FUCOs of $1,920,829,000. This investment represents approximately 54.2%
of  $3,544,649,000,  the average of the  consolidated  retained  earnings of AEP
reported on Forms 10-Q and 10-K for the four consecutive quarters ended June 30,
2000.  However,  AEP was  authorized  to invest  up to 100% of its  consolidated
retained earnings in EWGs and FUCOs (HCAR No. 26864,  April 27, 1998) (the "100%
Order") in File No. 70-9021. Although AEP's aggregate investment exceeds the 50%
'safe harbor'  limitation  contained in Rule 53, AEP's  aggregate  investment is
below the 100% limitation authorized under the 100% Order.

      As of  September  30,  1997,  the most recent  period for which  financial
statement  information  was  evaluated  in the 100%  Order,  AEP's  consolidated
capitalization consisted of 47.4% common and preferred equity and 52.6% debt. As
of June 30, 2000, AEP's  consolidated  capitalization  consisted of 36.2% common
and preferred  equity and 63.8% debt. The requested  authorization  will have no
impact on AEP's  consolidated  capitalization  ratios on a pro forma basis.  AEP
believes this ratio remains within acceptable ranges and limits.  Further, AEP's
interests  in EWGs and FUCOs have  contributed  positively  to its  consolidated
earnings.

      AEP will continue to maintain in conformity  with United States  generally
accepted accounting principles and make available the books and records required
by Rule 53(a)(2).  AEP does,  and will continue to, comply with the  requirement
that no more  than 2% of the  employees  of  AEP's  electric  utility  operating
subsidiaries shall, at any one time, directly or indirectly,  render services to
an EWG or FUCO in which AEP directly or indirectly owns an interest,  satisfying
Rule  53(a)(3).  And  lastly,  AEP will  continue to submit a copy of Item 9 and
Exhibits  G and H of AEP's Form U5S to each of the  public  service  commissions
having  jurisdiction  over the retail rates of AEP's electric utility  operating
subsidiaries,  satisfying Rule 53(a)(4). Rule 53(c) is inapplicable by its terms
because  the  proposals  contained  herein do not  involve the issue and sale of
securities  (including  any  guarantees)  to finance an acquisition of an EWG or
FUCO.

      Rule 53(b).  (i) Neither AEP nor any  subsidiary  of AEP is the subject of
any pending bankruptcy or similar  proceeding;  (ii) AEP's average  consolidated
retained  earnings for the four most recent quarterly  periods  ($3,544,649,000)
represented an increase of  approximately  $40,644,000  (or 1.2%) in the average
consolidated   retained  earnings  from  the  previous  four  quarterly  periods
($1,693,698,000); and (iii) for the fiscal year ended December 31, 1999, AEP did
not report operating losses attributable to AEP's direct or indirect investments
in EWGs and FUCOs.

      As noted,  AEP was  authorized  to  invest up to 100% of its  consolidated
retained  earnings in EWGs and FUCOs.  In connection with its  consideration  of
AEP's  application for the 100% Order, the Commission  reviewed AEP's procedures
for evaluating EWG or FUCO investments.  Based on projected financial ratios and
on procedures and conditions established to limit the risks to AEP involved with
investments in EWGs and FUCOs, the Commission  determined that permitting AEP to
invest up to 100% of its consolidated  retained earnings in EWGs and FUCOs would
not have a substantial  adverse impact upon the financial  integrity of the AEP,
nor would it have an adverse  impact on any of its  electric  utility  operating
subsidiaries  or their  customers,  or on the  ability of state  commissions  to
protect the electric utility operating subsidiaries or their customers.


ITEM 4.  REGULATORY APPROVAL

No Federal or State  commission or regulatory  body, other than this Commission,
has  jurisdiction  over the proposed  transactions  for which  authorization  is
requested herein.


ITEM 5.  PROCEDURE

      It is requested,  pursuant to Rule 23(c) of the Rules and  Regulations  of
the Commission,  that the Commission's order granting,  and permitting to become
effective this Post-Effective Amendment No. 9 be issued on or before November 6,
2000.  Applicants  waive any recommended  decision by a hearing officer of or by
any other  responsible  officer of the  Commission and waives the 30-day waiting
period  between  the  issuance of the  Commission's  order and the date it is to
become effective,  since it is desired that the Commission's order, when issued,
becomes effective forthwith.

      Applicants  respectfully  request that  appropriate  and timely  action be
taken by the  Commission in this matter in order that the business of Energy may
continue without  interruption  upon the termination of the present authority on
December 31, 2000.

      Applicants consent to the Office of Public Utility Regulation assisting in
the preparation of the Commission's decision and/or order in this matter, unless
the Office opposes the matter covered by this Post-Effective Amendment No. 9.


ITEM 6.  EXHIBITS AND FINANCIAL STATEMENTS

Exhibit F       Opinion of Counsel  (To be filed by amendment)

Exhibit G       Form of Notice


ITEM 7.  INFORMATION AS TO ENVIRONMENTAL EFFECTS

      As  described in Item 1, the  proposed  transactions  are of a routine and
strictly financial nature in the ordinary course of AEP's business. Accordingly,
the  Commission's  action in this matter will not  constitute  any major federal
action  significantly  affecting the quality of the human environment.  No other
federal agency has prepared or is preparing an  environmental  impact  statement
with regard to the proposed transactions.

      Pursuant to the  requirements of the Public Utility Holding Company Act of
1935, the undersigned  companies have duly caused this statement to be signed on

      American Electric Power Company,  Inc. ("AEP"), a New York corporation and
a registered  holding  company under the Public Utility  Holding  Company Act of
1935, as amended (the "1935 Act"), Central and South West Corporation,  ("CSW"),
a registered holding company under the 1935 Act and a wholly-owned subsidiary of
AEP,  and CSW  Energy,  Inc.  ("Energy"),  an indirect  subsidiary  of AEP and a
wholly-owned   non-utility  subsidiary  of  CSW,  have  filed  a  post-effective
amendment to their application-declaration previously filed and amended pursuant
to the Public  Utility  Holding  Company Act of 1935,  as amended  ("1935 Act"),
designating of the 1935 Act and Rule 45 thereunder as applicable to the proposed
transaction.

      Pursuant  to an order of the  Commission  dated  August 6, 1993  (HCAR No.
25866) (the "1993 Order") with respect to the  Application-Declaration,  CSW and

million.  This Guarantee authority was increased from $50 million to $75 million
by order of the  Commission  dated November 28, 1995 (HCAR No. 26416) (the "1995

sometimes collectively referred to herein as "the Orders".

      CSW became a wholly owned subsidiary of AEP on June 15, 2000,  pursuant to
an order of the Commission dated June 14, 2000 (HCAR No. 27186).

      AEP, CSW and Energy hereby request that the  Commission  authorize (a) the
