    TXU REPORTS IMPROVED FIRST QUARTER RESULTS; PROGRESS ON INITIATIVES, AND
                               INCREASED OUTLOOK

DALLAS - MAY 5, 2005 - TXU Corp. (NYSE: TXU) today reported consolidated results
for the first quarter ended March 31, 2005.

o    For the first quarter of 2005, TXU reported net income available for common
     stock of $416 million,  representing a loss of $0.19(1) per share, compared
     to net income of $173 million, or $0.49 per share for 2004.

o    Operational  earnings(2),  which exclude  special  items  and  discontinued
     operations,  for the first  quarter  of 2005 were $246  million,  $1.01 per
     share,  compared to $149  million,  $0.43 per share for 2004, a 135 percent
     increase in per share earnings.

o    The outlook for  operational  earnings  for 2005 was  increased to $6.25 to
     $6.45 per share,  and the growth  rate for 2006  relative  to this  revised
     outlook base was maintained at 16 to 20 percent. For details see page 9.

REPORTED EARNINGS
For the first quarter of 2005,  reported earnings of $416 million include income
from discontinued  operations(3) of $15 million, or $0.06 per share. Income from
continuing operations was $406 million,  representing a loss of $0.23 per share,
for the first quarter 2005  compared to income of $128 million,  $0.37 per share
for the prior year  period.  Income  from  continuing  operations  for the first
quarter of 2005 includes  income from special items,  primarily  associated with
the benefits of reductions in tax reserves and  litigation  settlement  expenses
net of transitional Capgemini outsourcing costs and other  restructuring-related
expenses,  totaling $155  million,  $0.64 per share.  For reported  earnings per
share purposes,  the dilution calculation also subtracts $462 million related to
the estimated true-up (as of March 31, 2005) on the company's  accelerated share
repurchase program.  Reported earnings of $173 million, $0.49 per share, for the
first quarter of 2004 include  losses from special  items of $26 million,  $0.07
per share and income from  discontinued  operations  of $50  million,  $0.13 per
share. Special items are discussed in more detail on page 3.

Reported and operational earnings per share are diluted. For periods when common
stock  equivalents  are not dilutive,  diluted  shares are equal to basic shares
outstanding.

OPERATIONAL EARNINGS
The 135 percent  increase in  operational  earnings  per share,  which  excludes
special  items  and the  effect  of the  accelerated  share  repurchase  program
true-up,  reflects  improved  performance  from the TXU Energy  Holdings and TXU
Electric Delivery segments, reduced corporate expenses, and fewer average common
shares outstanding.

"The first quarter  results are a solid start to delivering on our 2005 outlook,
in spite of  unsustainably  low  margins  and robust  competition  in the retail
business,  and very  volatile  commodity  prices,"  said C. John  Wilder,  chief
executive officer, TXU Corp. "We continue to progress in transforming TXU into a
high-performance  industrial company through a focus on operational  excellence,
market leadership, and performance management."


- ----------------------------
(1) A description of the  calculation of diluted  earnings per share is provided
    in Table 2 on page 3. The  primary  reason for  positive  net income  versus
    negative  diluted  earnings per share is,  pursuant to accounting  rules, an
    adjustment to net income for purposes of calculating  earnings per share for
    the $462 million change during the quarter in the estimated  true-up payment
    related  to the  company's  52.5  million  share  accelerated  common  stock
    repurchase in November  2004,  which is expected to be settled in the second
    or third quarter of 2005.

(2) Operational  earnings  is a non-GAAP  measure  that  adjusts  net income for
    special  items.  See  Attachment  1:  Financial  Definitions  for a detailed
    definition  of  operational  earnings and other GAAP and non-GAAP  financial
    measures used in this release.

(3) See Appendix Table L for details of discontinued operations.

Table 1 below  provides  a  recap  of  operational  highlights  and  significant
transactions completed since the beginning of 2005.

TABLE 1: 2005 HIGHLIGHTS
================================================================================
DATE                                      HIGHLIGHT
- ------------- ------------------------------------------------------------------
01-21          Reached a  comprehensive  settlement of shareholder  class-action
               litigation initially filed in Oct. 2002. The agreement,  which is
               subject  to final  court  approval  and in which TXU  denies  any
               liability, benefited shareholders and the company by removing the
               distractions,   expense,  and  uncertainty  that  accompany  such
               litigation.
.............. ..................................................................
01-27          Announced a comprehensive  agreement  resolving  potential claims
               related to TXU Europe Ltd. and its  affiliates and major creditor
               groups.  The  agreement  is  contingent  in  part  upon  creditor
               approval of the  bankruptcy  plan.  While such  approval has been
               received,  two creditor groups  subsequently filed an application
               in UK  court  objecting  to the  plan.  TXU  expects  that  these
               objections  will be resolved but that completion of the agreement
               will be delayed  until the third or fourth  quarter of 2005.  The
               agreement benefits the parties by providing  additional funds for
               creditors,  eliminating a potential  protracted  claim proceeding
               that could have  included  claims of  billions  of  dollars,  and
               closing a difficult chapter in TXU's history.
.............. ..................................................................
02-01          Offered  the  capacity  from 61 percent of its  natural-gas-fired
               Texas   generating   fleet  for   contract   (through  a  tolling
               arrangement)  or for sale.  This request for  proposal,  which is
               expected  to be  completed  in  phases  in the  second  and third
               quarters,  will help TXU Power  ensure it  remains  competitively
               priced, highly dependable,  and flexible to meet the needs of the
               market.
.............. ..................................................................
02-01          Launched TXU ENERGY  REWARDS+,  a  one-of-a-kind,  internet-based
               program for retail electricity  customers that offers merchandise
               and  services at prices that are up to 45 percent  lower than the
               most popular  online  travel and shopping  sites.  Early  results
               indicate  the new  loyalty  program  is being  well  received  by
               customers as over 30,000 have joined during the pilot.
.............. ..................................................................
03-31          Amended  subsidiary  credit  facilities,  increasing the capacity
               from $2.5 billion to $3.5 billion,  lowering the borrowing  costs
               and extending the maturity dates.  These actions further evidence
               the strength of TXU's business.
.............. ..................................................................
04-15          Opened the Power Optimization  Center (POC), a  state-of-the-art,
               fleet-level  diagnostic  facility  designed to provide  real-time
               monitoring  of TXU's power  plant  performance  systems.  The POC
               integrates  telecommunications and on-line technologies to detect
               plant and  equipment  performance  issues,  resulting in improved
               heat rates and reliability at the plants.
.............. ..................................................................
04-15          Filed a request with the Public  Utility  Commission  of Texas to
               raise retail  electricity  prices in native North Texas  markets,
               reflecting  the more than 20  percent  increase  in  natural  gas
               prices since the last adjustment in August 2004. Since the retail
               electricity  market  in  Texas  opened  to  competition  in 2002,
               natural gas prices have increased  more than 170 percent.  If the
               requested increase of 9.9 percent on an average  residential bill
               is  approved,  electricity  prices would have  increased  only 25
               percent from prices before the market opened.  TXU Energy's price
               to beat will remain one of the lowest in the state.
.............. ..................................................................
04-28          Comanche  Peak  Unit 2  synchronized  to the grid  after a 32 day
               planned refueling and maintenance outage, 3 days earlier than the
               35 day target.
.............. ..................................................................
05-04          Signed a definitive agreement to sell TXU's Pedricktown gas-fired
               cogeneration facility located in New Jersey for $8.5 million. The
               closing of the sale is  expected  to occur in the second or third
               quarter of 2005.
.............. ..................................................................
05-05          Announced the intent to increase the accelerated share repurchase
               program  by 6  million  shares,  consistent  with  the  company's
               previously  disclosed plan to offset share issuances and maintain
               average   diluted   shares  of  common   stock   outstanding   at
               approximately 240 million for 2005. Details of the agreement will
               be filed with the  Securities  and Exchange  Commission in a Form
               8-K.

============================================================================================================================


Special items in the first quarter of 2005  accounted for income of $155 million
after tax, or $0.64 per share of common stock.  These benefits relate  primarily
to the reduction of $138 million of the company's  federal  income tax valuation
allowance  reserve  related to the write-off of its investment in TXU Europe due
to the anticipated ability to utilize additional capital losses and the expected
receipt of an  additional  $23 million ($35 million  before tax) from  insurance
carriers  related to the  settlement  of the  securities  class  action  lawsuit
announced  in  January  2005.  For the  first  quarter  of 2004,  special  items
accounted  for a loss of $26 million  after tax or $0.07 per share and  resulted
primarily from costs associated with the company's restructuring and improvement
program and one-time  compensation  expense as disclosed in 2004. Because of the
nature and significance of these items, presentation of results after adjustment
for  the  items  allows  for  a  more  meaningful  analysis  of  the  underlying
performance of the business. Special items are described in Appendix Table A.

The  calculation of reported  earnings per share also includes the effect of the
estimated  true-up on the price of the company's  accelerated  share  repurchase
agreement  entered in November 2004.  The effect of the estimated  adjustment on
reported  (GAAP)  earnings  per share is to reduce  net  income to common by the
estimated $462 million change in the true-up during the quarter ending March 31,
2005.  Although  impacting the diluted  earnings per share, the true-up will not
affect net income when paid.

Under  the  terms of the  repurchase  agreement,  the  counterparty  immediately
borrowed shares of TXU Corp. common stock that were sold to and cancelled by TXU
Corp. at an initial price of $64.57 per share. The  counterparty  then purchases
an  equivalent  number of shares in the open market to return the shares.  Under
the  agreement,  the  initial  price that TXU Corp.  paid for the shares will be
adjusted to the actual price paid for the shares by the counterparty in the open
market plus related


- ---------------------------
(4) For the  first  quarter  2005,  the  dilution  calculation  for  operational
    earnings  reflects the addition to net income of interest on the convertible
    senior  notes of $0.1  million  after tax and  addition of 5 million  shares
    related  primarily to the effect of share-based  compensation (3.4 million),
    the convertible senior notes (0.7 million) and the equity-linked  securities
    (0.8  million).  The diluted  earnings  per share  calculation  for reported
    earnings  reflects a reduction of net income by the $462  million  change in
    the  estimated  cost  of the  true-up  of  the  company's  share  repurchase
    agreement  during the quarter and divides the reduced  amount by the average
    basic shares.  For the first quarter 2004 reported and operational  earnings
    dilution calculation,  the $13 million after-tax interest expense on the TXU
    Energy Co. exchangeable  preferred membership interests (EPMIs),  which were
    repurchased  by TXU Corp. on April 26, 2004, are added to net income and the
    related 57 million shares are added to the share average share count.

settlement  fees and expenses.  As of March 31, 2005,  approximately  66% of the
shares had been  purchased  at an average  price of  $69.82.  Had the  remaining
shares  been  purchased  at the $79.63  closing  share  price on that date,  the
estimated change between December 31, 2004 and March 31, 2005 in the amount that
TXU Corp.  would pay for the  adjustment  to the  initial  share  price was $462
million.

As of May 3, 2005,  approximately  84% of the shares had been  repurchased at an
average price of $72.73.  If the remaining  shares are repurchased at the $81.65
closing share price on that date,  the estimated  true-up  payment would be $540
million.  While TXU Corp.  has the option under the agreement to pay the true-up
in cash and/or  common stock,  it currently  expects to make the payment in cash
from credit facility borrowings and repay those borrowings with free cash flows.
The timing of the true-up is currently estimated to be June 2005.

Q1 05 OPERATIONAL EARNINGS                            246           1.01
=========================================================================

Operational  earnings were $1.01 per share of common stock,  up 135 percent from
$0.43 per share in the first  quarter  of 2004.  The  increase  was  driven by a
reduction in the average shares  outstanding,  a $0.21 per share  improvement in
operational  earnings from the TXU Energy  Holdings  segment,  a $0.02 per share
improvement in operational earnings from the TXU Electric Delivery segment and a
$0.03 reduction in corporate expenses.  The decrease in average shares of common
stock was primarily due to the repurchase of TXU Energy  Company's  exchangeable
preferred  membership  interests  in April 2004,  and  approximately  84 million
shares of TXU Corp.  common stock between May and November  2004,  inclusive.  A
more detailed review of variances by segment is provided below.

CASH FLOW AND FINANCIAL FLEXIBILITY
For the quarter ended March 31, 2005, cash provided by operating  activities was
$197 million compared to $338 million for 2004. The decrease  primarily reflects
a payment of $84 million in settlement of the  securities  class action  lawsuit
announced  in January  2005,  which is net of $66 million of  insurance  carrier
proceeds  received through March 31. An additional $35 million recovery has been
agreed to with  carriers  and is expected to be received  later this month.  The
variance  also includes a $42 million tax payment in 2005  associated  with 2004
results.

BUSINESS SEGMENT RESULTS
The following is a discussion of operational  earnings by business segment.  TXU
Corp.'s  business  segments  include  the TXU  Energy  Company  LLC (TXU  Energy
Holdings segment), TXU Electric Delivery, and Corporate operations.

TXU ENERGY HOLDINGS SEGMENT
TXU Energy Company LLC, the  unregulated  business  segment (TXU Energy Holdings
segment),  consists of electricity generation (TXU Power) and consumer, business
and wholesale markets activities  (collectively,  TXU Energy).  These businesses
are effectively  managed as one business through the wholesale  markets function
that  captures  the natural  hedge  inherent  between the retail and  generation
businesses.  TXU Power and the retail  business of TXU Energy are separate legal
entities that, in accordance with regulatory requirements, operate independently
within the competitive Texas power market.

TXU ENERGY HOLDINGS SEGMENT: OPERATIONAL PERFORMANCE
TXU  Energy  (consumer,  business,  and  wholesale  markets)  continued  to make
progress  toward  operational  excellence  and  market  leadership  in the first
quarter of 2005.

Competition in consumer markets  remained robust,  primarily driven by increased
competitor  marketing and higher  discounting  despite  declining  headroom as a
result of  increased  natural gas and power  prices.  Net  residential  customer
attrition  was 1.2% for the  quarter,  down from 2.1% the  previous  quarter but
higher than the 0.5% net growth  experienced  during Q1 2004,  primarily  due to
higher native market switching than a year ago when competitive activity was low
and  reduced  levels  of  customers  returned  to TXU  Energy  from  competitive
retailers  due to  non-payment.  However,  as TXU Energy  continues  to focus on
customer  service  improvements  and bad debt  reduction  efforts,  the relative
profitability   of  the  customer  base  continues  to  improve.   For  example,
approximately 50 percent of the customer  attrition was from customers with poor
payment history in the past 12 months.

TXU Energy  expects  to launch  several  initiatives  during the summer of 2005,
including  retention  programs and  competitive  offers,  to reduce the level of
switching during this period of high competition. These include expansion of the
successfully piloted TXU Rewards+ program in North Texas. The internet-based TXU
Energy Rewards+ program,  a loyalty program allowing TXU Energy customers to use
Rewards dollars to obtain discounts on the purchase of travel, entertainment and
merchandise  of up to 45 percent lower than popular  on-line travel and shopping
sites, was launched in February.  Over 30,000 customers have joined this program
since it began, and expansion of the program is underway. In addition, to remain
aggressive in acquiring  and  retaining a high-value  customer mix, an assertive
advertising  campaign is being launched outside of TXU Energy's native market to
highlight the benefits of switching to TXU Energy.  These  programs are expected
to increase profitable  customer  acquisitions since TXU Energy has improved its
bad debt management capabilities and lowered its cost to serve customers through
the Capgemini agreement. For the year TXU Energy expects native market attrition
to range from 7 to 8 percent  as  compared  to  previous  forecasts  of around 5
percent.

                                       5

================================================================================


================================================================================

TXU Energy also continues to improve the customer  experience.  Average speed to
answer  customer  calls for the  quarter  was 12  seconds  compared  to over 110
seconds  in the  prior  year  period.  Customer  time  in the  integrated  voice
recognition  system  (IVR) was down 28 percent  from the prior year period to 78
seconds.  PUC  complaints  were also down by 42 percent from the prior year. The
Capgemini   Energy   partnership  has  assisted  in  delivering   these  service
improvements  and is  expected  to deliver  an  estimated  $115  million of SG&A
expense savings  system-wide in 2005 as compared to 2003, of which approximately
30 percent was realized in 2004. TXU Energy also  continues to make  substantial
progress  in  reduction  of bad debt  expense  with an  additional  $15  million
reduction in the first quarter as compared to the prior year period.

Competition  also remains robust in business  markets.  The churn rate for small
and medium  businesses  remained at about the fourth quarter 2004 pace even with
increased  power prices  reducing  headroom during the first quarter of 2005. In
response,  TXU Energy has expanded and enhanced the  telephone  and direct sales
forces. The acquisition process for new small and medium customers has also been
streamlined  by  eliminating  several  steps and improving  monitoring  which is
expected to significantly  increase its effectiveness,  simplify the process for
customers  and reduce the time required to complete the  acquisition.  For large
commercial and industrial  customers,  delivered volumes decreased 35 percent to
4.4 TWh as  compared  to 6.7  TWh in the  first  quarter  2004,  reflecting  TXU
Energy's  change in  strategy  in 2004 to focus on more  profitable  margins and
continued fierce  competition in the market.  Along with the change in strategy,
the business  markets group has improved its contracting  activity  through more
effective sales coverage and by reducing selling costs by over 35 percent.

TXU Power achieved several  significant  milestones  during the first quarter of
2005.  Excluding planned outages, TXU Power's nuclear plant safely produced at a
100.1 percent capacity factor  outperforming  the 99.2 percent level in the same
period of 2004. Unit 2 recently  completed a planned  refueling  outage that was
completed  safely  and in 32  days,  or 3 days  less  than  the  targeted  plan.
Performance  from the lignite  fleet also improved with high levels of reliable,
low cost output,  achieving  an  aggregate  capacity  factor  excluding  planned
outages of 96.0  percent as  compared  to 92.3  percent in the first  quarter of
2004.  The lean  operating  techniques  of the TXU  Operating  System have had a
dramatic and positive impact on the fleet performance.  Planned outage durations
have been reduced by approximately nine percent,  while maintaining the scope of
the maintenance performed.  Cycle times for equipment repairs, such as draglines
and coal  crushers  have also been  safely cut by 25 to 30  percent,  increasing
availability and output.  This and other TXU Operating System  improvements have
been achieved by fully engaging  employees and  contractors  in identifying  and
eliminating   waste  and  delivering   sustainable   operational   and  earnings
improvements.  In  mid-April,  TXU Power  opened the Power  Optimization  Center
(POC). The POC utilizes  telecommunications  and on-line  technologies to detect
plant  performance  issues  before they become a problem,  resulting in improved
heat  rates  and  reliability  at  the  plants.  The  POC is  already  improving
reliability by identifying elevated vibration and temperature trends in fans and
motors at TXU Power's lignite and nuclear plants.

TXU ENERGY HOLDINGS SEGMENT: FINANCIAL PERFORMANCE
In the first quarter of 2005, the TXU Energy  Holdings  segment  reported income
from  continuing  operations  of $0.85 per share,  a 174 percent  increase  over
income from  continuing  operations  of $0.31 per share in the first  quarter of
2004.  Special  items for the first quarter 2005 were $2 million,  or $0.01,  as
detailed in Appendix Table A. Operational  earnings in the first quarter of 2005
were $0.85 per share as compared to $0.33 per share in the prior year period,  a
158 percent  increase.  Excluding  the effect of lower average  shares,  the TXU
Energy Holdings segment operational earnings improved by $0.21 per share.

======================================================================

The $44 million ($0.11)  increase in  contribution  margin for the first quarter
2005 versus the  comparable  2004 period  reflects  higher  retail and wholesale
prices  (primarily  driven by increased  natural gas prices),  increased lignite
generation plant output, and more effective replacement of gas plant output with
lower cost purchased power.  These increases were partially offset by the effect
on  contribution  margins  of  decreased  retail  sales  volumes  due to  robust
competition,  milder weather  (approximately $13 million in margin versus normal
weather and $5 million  versus the prior year period),  and reduced  hedging and
risk  management  activities  revenue.  The  decline in  operating  costs of $15
million was primarily due to reduced expenses  resulting from the dissolution of
the  customer  services  agreement  with  TXU Gas and the  sale of the TXU  Fuel
assets, both of which have associated  reductions in contribution  margin..  The
decline also  reflects $3 million in lower  pension and  postretirement  benefit
costs.

                                       6

================================================================================


================================================================================

The reduction in depreciation and amortization  expense was primarily the result
of reductions in the 2005 depreciation rates for lignite  generation  facilities
assets due to an  increase in the  estimated  average  depreciable  lives of the
assets and decreased  depreciation  expense associated with TXU Fuel assets sold
in June 2004.  SG&A  expenses for the first quarter of 2005 declined $35 million
primarily due to reductions in shared  services  costs of $12 million  including
the effects of the  Capgemini  agreement,  reductions  in pension  and  benefits
expenses and  incentive  plan  accruals,  and decreased bad debt expenses of $15
million as a result of stricter  disconnect  policies,  more focused  collection
activities and lower accounts receivable balances.  Other deductions include the
benefit of a $15 million  reduction to the  estimated  combustion  turbine lease
impairment  recorded in 2004.  The  adjustment  was made to reflect the value of
bids received in the offer to lease the units under a tolling  agreement.  Other
deductions  also include a $12 million  provision for default by a  counterparty
under a coal supply contract.

Total retail electricity revenues for the quarter ended March 31, 2005 decreased
$148  million,  10.5  percent as compared to the 2004  period  primarily  due to
decreased sales volumes resulting from the effects of retail customer losses and
milder weather,  partially offset by higher retail prices,  reflecting increased
natural gas prices.  Wholesale  electricity revenues increased $50 million, 10.7
percent, due to higher wholesale prices, somewhat offset by lower sales volumes.
The  decrease of $11 million in other  revenues  for the first  quarter  2005 as
compared to the prior period is primarily associated with the dissolution of the
customer services  agreement with TXU Gas and the sale of the TXU Fuel assets in
June 2004.  Appendix Table B provides details of operating  revenues for the TXU
Energy Holdings  segment for the first quarter of 2005 compared to previous year
period.

Revenues from hedging and risk management  activities  decreased $45 million for
the quarter ended March 31, 2005 versus the comparable 2004 period. The decrease
includes $18 million in losses related primarily to short term positions used to
hedge gas  commodity  price risk.  It also  includes  an $8 million  increase in
credit   reserves  due  to  increased   commodity   prices  and  $6  million  in
mark-to-market losses on economic hedges on gas storage expected to be offset by
accrual  gains later in the year.  Because  hedging  activities  are intended to
mitigate  the risk of commodity  price  movements on revenues and cost of energy
sold,  the changes in such results  should not be viewed in isolation but rather
taken together with the effects of price and cost changes on margins.

As shown in Appendix  Table F, the total cost of energy sold and  delivery  fees
decreased $198 million,  15.8 percent for the first quarter 2005 compared to the
prior year quarter  primarily  due to a decrease in sales  volumes.  The segment
contribution  margin percent improved due to more efficient base load generation
and lower levels of natural gas generation and purchased power, partially offset
by higher prices of natural gas and  purchased  power and an increase in average
delivery fees.

Appendix  Table G  provides  a  quarter-to-quarter  summary  of the  TXU  Energy
Holdings  segment  generation and supply operating  statistics.  Results for the
2005 quarter  depict the benefit of more effective  sourcing of purchased  power
versus  higher  heat rate  natural  gas-fired  generation  as well as  increased
production from the lignite generation plants. The increase in gas and purchased
power  prices for 2005 was the  result of higher gas  prices.  The  increase  in
lignite production was primarily due to improved operating performance,  reduced
planned and unplanned outages and the timing of maintenance outages. The lignite
plants achieved record  production  levels in 2004 and are on pace to improve on
those levels in 2005.

Appendix Tables C through E provide TXU Energy customers and volumes statistics.
For the first  quarter  2005,  the 20%  decrease  in  retail  sales  volumes  is
predominantly  due  to a  decrease  in  customers  in  the  competitive  market,
especially  larger business  customers,  and reduced overall usage due to milder
weather.  Native market  residential  customer levels declined 1.3 percent since
year-end and 6.3% versus the first quarter of 2004.  The 16% decrease in average
small business  segment  volumes for the quarter is primarily due to competitive
activity,  especially  for  larger  customers  in this  customer  segment;  this
competitive  intensity is evident throughout the state. The 35% decline in large
business  volumes  reflects a change in strategy  to focus on margin  instead of
volumes.

TXU ELECTRIC DELIVERY SEGMENT
TXU's  Electric  Delivery  segment  continued  to make  progress on its goals of
delivering  operational  excellence  in system  reliability  and  maintaining  a
position of cost leadership. In the first quarter 2005, the segment delivered at
or near top-decile  performance in O&M expense per distribution customer and O&M
expense per MWh.

TXU ELECTRIC DELIVERY SEGMENT: OPERATIONAL HIGHLIGHTS
For the 2005 quarter,  the three key metrics used to measure  reliability showed
improvement  over the  comparable  2004  period.  The first  quarter 2005 System
Average  Interruption  Duration  Index  (SAIDI)  minutes  of 72.76,  placed  TXU
Electric Delivery among top quartile reliability performers and was a 12 percent
improvement over the same period in 2004. TXU Electric Delivery's System Average
Interruption  Frequency Index (SAIFI) improved from 1.04 in 2004 to 0.92 in 2005
- -- also a 12 percent  increase.  Additionally,  the first  quarter 2005 Customer
Average  Interruption  Duration  Index  (CAIDI)  improved  to  78.72,  a  slight
improvement over 2004. As current reliability initiatives begin to be more fully
realized in 2005 and 2006, TXU Electric Delivery expects further  improvement in
these key metrics.

Excluding  the  $0.11 per share  benefit  of  reduced  average  shares,  the TXU
Electric  Delivery  segment's  contribution  for the first quarter  increased by
$0.02 per share from the prior year period. The improved  performance  reflected
an  increase  of $8  million  ($0.02 per share pre tax) in  contribution  margin
(revenues),  excluding  transition  revenue,  due to increased  transmission and
other tariff  revenues,  offset in part by decreased  consumption  due to milder
weather. Revenues also increased $19 million related to transition revenue under
tariffs to service  securitization bonds which have offsetting  depreciation and
amortization  expense.  The  increase  in  operating  costs  was the  result  of
increased third party  transmission  costs and property  taxes.  The $18 million
increase in  depreciation  and  amortization  expense was  primarily  due to $19
million  ($0.05 per share  pre-tax) of  amortization  of regulatory  assets as a
result of  securitization  bonds  issued in June 2004 for which  there are equal
associated  transition  revenues.  The major  factors in decreased  net interest
(interest  expense net of interest income) were higher  reimbursements  from the
TXU Energy Holdings segment related to securitized  regulatory  assets and lower
average interest rates.

Appendix  Tables J and K summarize  the details of the  operating  revenues  and
operating  statistics,  respectively,  for the TXU Electric Delivery segment for
the first quarter of 2005 as compared to the first quarter of 2004.

CORPORATE AND OTHER
Corporate and Other  consists of TXU Corp.'s  remaining  non-segment  operations
consisting primarily of general corporate expenses, equity earnings or losses of
unconsolidated  affiliates,  and interest on debt  outstanding  at the corporate
level.  Income  from  continuing  operations  for  Corporate  and Other was $132
million,  or a loss of $1.38  per  share,  reflecting  the  dilution  adjustment
related to the share repurchase estimated true-up, for the first quarter 2005 as
compared to a loss of $53 million,  $0.11 per share for the first  quarter 2004.
Excluding the effect of the accelerated share repurchase true-up,  special items
of $0.65 per  share,  and  deducting  preference  stock  dividends,  operational
earnings  were a loss of $0.14 per share in 2005 as  compared to a loss of $0.07
per share in 2004.

Excluding the effect of reduced  shares,  current  period  operational  earnings
improved  by $0.03 per share  from the prior year  period.  The  improvement  is
primarily  related  to lower SG&A  expenses  and  increased  other  income.  The
improvements  in SG&A  expense  were  driven by reduced  services  expenses as a
result of the Capgemini  Energy agreement and reduced legal and consulting fees,
while  the   improvement  in  other  income  and  deductions  is  primarily  the
amortization of the deferred gain on the sale of the TXU Fuel assets.

DISCONTINUED OPERATIONS
Appendix Table L provides  details of the components of discontinued  operations
for the first quarter 2005 and 2004. For the first quarter of 2005,  income from
discontinued  operations of $15 million  primarily  reflects a $17 million after
tax benefit related to the TXU Gas sale as a result of favorable resolution of a
proposed  working capital  adjustment to the sales price.  The $50 million after
tax of  income  from  discontinued  operations  for the  2004  period  primarily
reflects  net income of $38  million  and $32 million and a net loss of $16 from
TXU Gas, TXU Australia, and TXU Communications respectively, which were disposed
through sale or merger  transactions  in 2004. The results of TXU Energy Company
LLC's  cogeneration  and wholesale  energy sales business in New Jersey are also
reflected in discontinued operations for both periods. As noted above, on May 4,
2005,  TXU Energy  Company LLC entered into a definitive  agreement to sell this
business.

2005 OUTLOOK
TXU is updating its operational earnings outlook(5) for 2005 to a range of $6.25
to $6.45 per share, an increase of 10 percent from the previous outlook of $5.65
to $5.85 per share.  As shown in Table 10, several  factors led to the change in
outlook.   The  primary  factor  was  the  substantial   increase  in  wholesale
electricity  prices  since  the  beginning  of the year,  driven by  significant
increases in natural gas prices.  This increases the estimated revenues from TXU
Power's  base load plants by a pro forma  estimate of $1.64 per share after tax.
As  previously  noted,  however,  TXU  Energy  Holdings  segment's  consolidated
portfolio  is  substantially  balanced  to natural  gas  prices in 2005.  Absent
changes in retail  prices to offset  increases  in the cost of goods  sold,  the
change in  natural  gas and  wholesale  market  prices  would lead  directly  to
compressed  margins in TXU  Energy.  By  submitting  the  requested  fuel factor
adjustment to the price-to-beat to reflect higher natural gas prices, TXU Energy
is expected  to offset at least a portion of the  increase in its cost of goods;
overall, net of the fuel factor adjustment TXU Energy's expenses are expected to
increase by a pro forma  estimate of $0.91 per share after tax.  The net overall
impact of the increase in natural gas and  wholesale  market  forward  prices is
$0.73 per share.

The increase in wholesale  market  prices and  resulting  change in retail rates
also is  expected to have some impact on  customer  switching,  customer  demand
elasticity,  and bad debt in the small business and residential markets; the net
impact is estimated to be a decrease of approximately $30 million,  or $0.08 per
share after tax. Interest expense (net of preferred  dividends) is also expected
to  increase  relative to prior  estimates  by $0.05 per share,  primarily  as a
result of the increase in the company's  share price this year and the impact on
the projected true-up payment for the accelerated  share repurchase  program and
the repurchase of the additional six million shares to achieve approximately 240
million average shares outstanding for the year.

In total, these changes increase the 2005 outlook for operational  earnings from
the  previous  estimate of $5.65 to $5.85 per share to $6.25 to $6.45 per share.
Of this total, the operational earnings of TXU Energy Holdings represent roughly
89  percent of the  midpoint  range;  TXU  Electric  Delivery  21  percent;  and
corporate/other negative 10 percent.

============================================================================================================================


Table 11 details the  phasing of the revised  outlook.  TXU's  previous  outlook
represented roughly 55 percent improvement in operational  earnings for the full
year 2005, or a 105 percent increase on a per share basis. In the first quarter,
operational  earnings exceeded last year's results by 65 percent, or 135 percent
on a per share basis.  For the remainder of the year,  with today's  increase in
outlook, TXU's operational earnings are estimated to improve by 69 to 77 percent
over the last  three  quarters  of 2004,  or 120 to 128  percent  on a per share
basis, corresponding to a full year outlook estimate for operational earnings of
$6.25 to $6.45 per share.

TXU expects cash flows to improve substantially in 2005 as a result of increased
earnings and operational improvements. Table 12 shows cash provided by operating
activities  and free cash flow for 2004 and  estimates  for 2005.  The change in
free cash flow from the previous  outlook is primarily  driven by the  increased
outlook for operational earnings, somewhat offset by a small increase in capital
expenditures due to the purchase of mining transportation  equipment rather than
financing through an operating lease.

The outlook for 2005 includes the expected  impact of  implementing  the Phase 2
improvement initiatives, which include among other items savings associated with
the Capgemini  Energy joint  venture;  the ongoing  success of the TXU Operating
System in improving productivity and output in the generation plants;  increased
efficiency in sourcing  purchased power and optimizing  production of TXU Energy
Holding's gas generation  fleet;  improving  margins in the large commercial and
industrial  business,  and other variables such as customer  retention rates and
weather. Successful execution of these improvement initiatives remains a primary
focus of the  management  team and the overall  implementation  program is going
well, despite challenges to TXU Energy Holding's margins in the first quarter.

Notwithstanding  the higher base of the revised 2005  outlook,  TXU is affirming
its expected  growth range of 16 to 20 percent in  operational  earnings in 2006
relative  to 2005 based on current  market  forward  natural gas curves and plan
assumptions.  Table 13 highlights the main drivers of expected growth, including
the net impact of higher wholesale  market prices.  Consistent with the approach
taken in 2004,  the  company  expects to  conduct a detailed  review of its 2006
business  plan over the summer,  review the plan with the Board of  Directors in
the fall,  and provide a more detailed  update on the 2006 outlook in October or
November 2005.

    million of cash special items in 2004.

================================================================================

ATTACHMENT 1: FINANCIAL DEFINITIONS

OPERATIONAL  EARNINGS (A NON-GAAP MEASURE):  Income from continuing  operations,
less special items and preference stock dividends. TXU believes that operational
earnings is a useful measure of underlying  results because of the magnitude and
scope of the performance  improvement  program and the significant effect of the
special  items on  reported  results.  TXU relies on  operational  earnings  for
evaluation of performance and believes that analysis of the business by external
users is enhanced by visibility  to both reported GAAP earnings and  operational
earnings.

OPERATIONAL EARNINGS PER SHARE (A NON-GAAP MEASURE):  Per share (diluted) income
from continuing operations net of preference stock dividends,  excluding special
items and the adjustment for the estimated cost of a true-up payment on the 52.5
million share  accelerated  common stock  repurchase.

CASH INTEREST EXPENSE (A NON-GAAP MEASURE): Interest expense and related charges
less  amortization  of discount and  reacquired  debt  expense plus  capitalized
interest.  Cash  interest  expense  is a measure  used by TXU to  assess  credit
quality.

EBIT (A NON-GAAP  MEASURE):  Income from continuing  operations  before interest
income,  interest expense and related charges, and income tax and special items.
EBIT  is a  measure  used  by TXU to  assess  performance.

EBITDA (A NON-GAAP MEASURE):  Income from continuing  operations before interest
income,  interest expense and related charges,  and income tax plus depreciation
and  amortization  and special items.  EBITDA is a measure used by TXU to assess
performance.

EBITDA/INTEREST (A NON-GAAP MEASURE): EBITDA divided by cash interest expense is
a  measure  used  by TXU to  assess  credit  quality.

DEBT/EBITDA  (A  NON-GAAP  MEASURE):   Total  debt  less  transition  bonds  and
debt-related restricted cash divided by EBITDA.  Transition,  or securitization,
bonds are  serviced  by a  regulatory  transition  charge on wires rates and are
therefore excluded from debt in credit reviews.  Debt-related restricted cash is
treated  as net  debt  in  credit  reviews.  Debt/EBITDA  is a  measure  used by
management to assess credit quality.

FREE CASH FLOW (A NON-GAAP MEASURE):  Cash provided by operating activities less
capital  expenditures and nuclear fuel. Used predominantly as a forecasting tool
to estimate cash available for dividends, debt reduction, and other investments.

INCOME  FROM  CONTINUING  OPERATIONS  PER  SHARE  (A GAAP  MEASURE):  Per  share
(diluted) income from continuing  operations before cumulative effect of changes
in accounting principles, before preference stock dividends.

CONTRIBUTION  MARGIN (A GAAP  MEASURE):  Operating  revenues less cost of energy
sold and delivery fees.

REPORTED  EARNINGS PER SHARE (A GAAP  MEASURE):  Per share  (diluted) net income
available to common shareholders.

RETURN ON AVERAGE  COMMON STOCK EQUITY BASED ON NET INCOME:  Twelve months ended
net income available for common stock (a GAAP measure) divided by the average of
the  beginning  and ending  common stock equity (a GAAP  measure) for the period
calculated.

RETURN ON AVERAGE COMMON STOCK EQUITY BASED ON OPERATIONAL  EARNINGS (A NON-GAAP
MEASURE):  Twelve months ended operational earnings (a non-GAAP measure) divided
by the average of the  beginning and ending common stock equity (a GAAP measure)
for  the  period  calculated.  This  measure  is used  to  evaluate  operational
performance and management effectiveness.

RETURN ON INVESTED  CAPITAL  BASED ON ADJUSTED NET INCOME (A NON-GAAP  MEASURE):
Twelve months ended net income (a GAAP measure) plus after-tax  interest expense
and related  charges net of interest  income on restricted cash related to debt,
divided by the average of the  beginning  and ending total  capitalization  less
debt-related restricted cash for the period calculated.  This measure is used to
evaluate operational performance and management effectiveness.

RETURN ON INVESTED  CAPITAL BASED ON ADJUSTED  OPERATIONAL  EARNINGS (A NON-GAAP
MEASURE):  Twelve months ended  operational  earnings (a non-GAAP  measure) plus
preference  stock dividends plus after-tax  interest expense and related charges
net of  interest  income on  restricted  cash  related  to debt,  divided by the
average of the  beginning  and ending  total  capitalization  less  debt-related
restricted  cash for the period  calculated.  This  measure is used to  evaluate
operational  performance and management  effectiveness.

SPECIAL ITEMS:  Unusual charges related to the implementation of the performance
improvement  program  and other  charges,  credits or gains that are  unusual or
nonrecurring.  The  performance  improvement  program  is being  implemented  in
phases,  and the charges are expected to occur largely within a one-year period.
Special  items are included in reported  GAAP  earnings,  but are excluded  from
operational earnings.  Special items associated with the performance improvement
program  include  debt  extinguishment  losses and costs  related  to  severance
programs, asset impairments and facility closures.

TOTAL CAPITALIZATION (A NON-GAAP MEASURE): Total debt plus shareholders equity.

TOTAL DEBT (A GAAP MEASURE):  Long-term debt (including  current portion),  plus
bank loans and commercial  paper plus  long-term debt held by subsidiary  trusts
plus preferred  securities of  subsidiaries,  including  exchangeable  preferred
membership interests (EPMIs).

TOTAL DEBT LESS TRANSITION BONDS AND RESTRICTED CASH (A NON-GAAP  MEASURE):  TXU
also uses a total debt measure that  excludes  transition  bonds and  restricted
cash.  Transition,  or  securitization,  bonds  are  serviced  by  a  regulatory
transition charge on wires rates and are therefore  excluded from debt in credit
reviews.  Debt-related restricted cash is treated as net debt in credit reviews.
TXU uses this measure to evaluate its debt and capitalization levels.
