                            CSW Submits Plan in Texas
                          for Transition to Competition

Dallas, Texas (Jan. 10, 2000) -- Central and South West Corporation (CSW) (NYSE:
CSR) today filed with the Public Utility Commission of Texas (PUCT) its business
separation  plan required by Texas Senate Bill 7 on Electric  Restructuring  (SB
7). The business  separation  plan  describes  the  approach  proposed by CSW to
separate,  or "unbundle," the activities of each of its Texas electric operating
companies  into  three  entities.  While  the  plan  is  directed  to  meet  the
requirements of the Texas restructuring legislation,  the separation plan should
also meet  restructuring  requirements  anticipated  in Arkansas,  Louisiana and
Oklahoma.

CSW is the parent company of Central Power and Light Company  (CPL),  West Texas
Utilities Company (WTU), Southwestern Electric Power Company (SWEPCO) and Public
Service Company of Oklahoma (PSO). CPL and WTU operate in Texas. SWEPCO operates
in portions of Texas, Louisiana and Arkansas. PSO operates in Oklahoma.

CSW's  separation  plan  describes  the proposed  approach that will be taken to
separate the  traditional  activities of its  integrated  electric  companies to
provide for competition in Texas. By Jan. 1, 2002, utilities must separate their
operations into three basic units:

- -   A retail electric provider (REP), which will sell electric service to retail
    customers;
- -   A  power  generation  company,  which  will  produce  the  electricity;  and
- -   An energy delivery  company (transmission  and  distribution, or T&D), which
    will deliver the electricity to the customer.

Based on the  experience by other  utilities in other states,  the total cost to
restructure the entire CSW system to implement retail  competition in its states
could range from $100 million to $200 million.

"The plan will ensure a smooth  transition for our customers  while  providing a
cost-effective  way to  separate  the  energy  delivery,  generation  and retail
business functions to comply with SB 7," said Mark Roberson,  CSW vice president
of  regulatory  affairs.  "The  proposed  separation  is  intended  to  minimize
restructuring costs for the benefit of our customers.

"The plan envisions a two-stage structural separation," Roberson continued. "The
first stage will be the  structural  separation of the management and control of
the  transmission  and  distribution  areas  from  the  generation  areas of the
corporation and the creation of a separate retail electric provider.  This would
occur on or before the Jan. 1, 2002, start date for retail competition in Texas.



"The  second  stage would  occur  after a  transition  period of up to six years
following the Jan. 1, 2002,  start date,"  Roberson  said. "By Jan. 1, 2008, CSW
will have  resolved in a  cost-effective  way existing  contracts  that restrict
transfers  of asset  ownership  and would have  transferred  legal  ownership of
generating and T&D assets to the new entities.  By that time,  operating  staffs
also  would  have  been  transferred  into  the  separate   generating  and  T&D
companies."

Taking this two-stage approach is expected to potentially save approximately $35
million in refinancing costs that likely would occur if there were a requirement
to transfer  asset  ownership by Jan. 1, 2002,  according to Wendy  Hargus,  CSW
treasurer.  Consequently,  CSW is asking the PUCT to  provide a  decision  on an
accelerated basis as to whether it will allow its proposed two-stage approach.

"Under the proposed  two-stage  structural  separation plan,  separate books and
records would be kept for each business  unit," Hargus said.  "Office,  computer
systems,  accounting systems and similar equipment would be segregated,  and the
employee Code of Conduct would restrict information exchanges among employees of
the  businesses.  Ownership of the power plants and T&D facilities will continue
on  the  books  of  our  individual  electric  operating  companies  during  the
transition period."

"Our goal in CSW's  reorganization  planning is to maintain the efficiencies and
economies  that have been achieved by the CSW system  through  consolidation  of
similar  activities  over the last several  years,"  Roberson said. "At the same
time, we must ensure that we meet the requirements  mandated by Texas SB 7 while
allowing the flexibility to meet the  requirements of Arkansas Act 1556, as well
as any restructuring requirements mandated in Louisiana or Oklahoma."

Central and South West  Corporation  is a Dallas-based  public  utility  holding
company  that owns four U.S.  electric  utility  subsidiaries  with 1.7  million
customers,  a regional  electricity  company serving 2 million  customers in the
United  Kingdom,  and  non-utility   subsidiaries   involved  in  energy-related
investments  as well  as  subsidiaries  that  offer  telecommunications,  energy
efficiency  and financial  transactions.  On December 22, 1997,  CSW announced a
definitive  merger  agreement for a tax-free,  stock-for-stock  transaction with
Columbus, Ohio-based American Electric Power Company, Inc.
