SHARP GROWTH IN NET INCOME IN ALL OF THE COMPANY'S BUSINESSES

-- The business in Spain and Portugal posted net income of Euro 568 million in the first quarter of 2006, an increase of 49.5%. This includes Euro 212 million of higher compensation, net of tax, for non-mainland generation in 2001-2005 pursuant to the Ministerial Orders passed on March 30, 2006.

-- EBIT was Euro 1,491 million, a 41.9% increase.

-- Cash flow from operations totalled Euro 1,299 million, 28.4% higher than in 1Q05.

ENDESA'S 1Q06 RESULTS CLEARLY SURPASSED THE TARGETS SET OUT IN THE2004-2009 STRATEGIC PLAN

-- The 87.9% increase in net income in 1Q06 is far above the pace envisaged in the 2004-2009 Strategic Plan presented to the markets on October 3, 2005 in the document "ENDESA: stronger business, greater value", which set a CAGR target of 12%.

-- The increase in EBITDA of 31% was also well above the target 2004-2009 CAGR of 10-11%.

-- Financial leverage at March 31, 2006 stood at 124.2%, 15.8 percentage points below the Strategic Plan's target.

SOLID FINANCIAL POSITION

-- Net financial debt at March 31, 2006 stood at Euro 18,760 million, a mere 2.6% increase from year-end 2005, mostly due to the financing of the tariff deficit in Spain in 2005 and 1Q06.

-- Regulatory items whose recovery has been recognised to the Company amount to Euro 3,038 million, so net debt excluding these amounts stands at Euro 15,722 million.

-- Net financial expenses were 13.1% lower than in the same period last year.

BUSINESS IN SPAIN AND PORTUGAL

Excellent performance; strong growth in net income

-- Net income from the business in Spain and Portugal increased by 49.5% to Euro 568 million and accounted for 54% of ENDESA's total net income.

-- As compared to 1Q05, EBITDA grew 25.9% to Euro 1,037 million and EBIT by 38.5% to Euro 773 million.

-- These sharp increases were achieved despite the impact of the Royal Decree Law 3/2006, which amounted to Euro 164 million and Euro 107 million on EBITDA and Net Income, respectively.

-- 1Q06 figures include a Euro 399 million asset related to the revenue shortfall from regulated activities in the period. Excluding this asset, the impact of this deficit in net income would have been Euro 259 million.

Completion of the regulatory framework for the non-mainlandsystems

-- The regulation of the non-mainland electricity systems is now in place. Application of the regulation implied Euro 887 million compensation to ENDESA for the 2001-2005 period, above the provisional amounts envisaged in the subsequent Royal Decree tariffs of each year. At December 31, 2005, ENDESA's financial statements included revenues of Euro 644 million in this connection, with the remaining Euro 243 million booked in 1Q06. Euro 212 million were recorded as sales while Euro 31 million as financial revenues.

-- With the new regulatory framework in place, non-mainland generation is guaranteed sufficient revenues going forward to meet the costs of the business and becomes hedged to fuel prices volatility, thereby ensuring a reasonable return.

-- Noteworthy is the completion of the regulatory framework for the non-mainland systems in line with the hypothesis considered under the 2004-2009 Strategic Plan.

ENDESA: Spain's leading electric utility

-- ENDESA still proves to have the largest share of the total electricity generation market and sales of any Spanish electric utility.

Output/sales balance

ENDESA met 88.3% of its total electricity sales in 1Q06 from itsown output. This balanced situation between output and demand shouldconsiderably reduce the risk of its electricity business, providingENDESA with a significant competitive advantage, especially in theSpanish market. In Spain, the Company met 86.6% of its demand in theperiod from its own output.

Revenue growth outstrips costs

ENDESA's total sales in 1Q06 rose 26% vs. 1Q05 to Euro 5,274million.

Sales growth was greater by value than by volume. This was due toincreases in electricity prices in the countries where ENDESAoperates, because of higher power generation costs.

The growth in sales covered the 35.8% increase in supply andservice costs (variable costs), which was caused by increases in fuelcosts, energy purchases and CO2 emission right prices in the period.

Sharp increases in gross margin, EBITDA and EBIT

The increase in revenues clearly offset the increase in costs. TheCompany reported significant rises in gross margin (+26.9%), EBITDA(+31%) and EBIT (+41.9%).

Net financial expenses: -13.1%

ENDESA reported negative financial results of Euro 214 million for1Q06, a 3.2% improvement over 1Q05.

Net financial expenses totalled Euro 232 million, 13.1% less thanin the year-ago period. This figure includes revenues of Euro 31million related to the portion not recorded at December 31, 2005 ofthe interest accrued on the compensations derived from the deficit onnon-mainland generation calculated in accordance with the MinisterialOrders passed in March 2006.

Worth highlighting is that the increase in net debt caused byfinancing of the revenue deficit on regulated activities in Spain doesnot impact net financial expenses. Both, the cumulate amount of thedeficit financed and the amounts pending collection as compensationfor the historical deficit on non-mainland generation, earn interestthat offset the cost.

Cash flow: Growth of 28.4%

Cash flow from operating activities through March 31, 2006 wasEuro 1,299 million, a 28.4% increase vs. the same period in 2005.

Solid financial position

ENDESA's net debt was Euro 18,760 million at March 31, 2006, just2.6% higher than at year-end 2005.

By business, debt declined by 4% in Europe and 3% in LatinAmerica, but increased by 1.2% in Spain and Portugal.

The average life of the ENDESA Group's debt at March 31, 2006 was5.5 years.

ENDESA enjoys a high degree of protection against interest-raterisk, since 79.3% of all its debt is either fixed-rate or hedged.

At March 31, 2006, ENDESA in Spain and its direct subsidiaries,excluding the Enersis Group, had liquidity of Euro 5,279 million, ofwhich Euro 4,632 million corresponded to unconditional undrawn creditlines. These balances are sufficient to cover maturities falling duein the next 34 months for this group of companies.

The Enersis Group held Euro 701 million of cash and cashequivalents, as well as Euro 403 million in unconditional undrawncredit lines. The total amount cover debt maturities for the next 10months.

Financial leverage ended 1Q06 at 124.2%, 10.8 percentage pointslower than at September 30, 2005 and 19.5% lower than at March 31,2005.

Comparisons with this ratio as of December 31, 2005 (112%) are notvery meaningful, as financial leverage at the end of 1Q06 reflects theimpact of the approval at the General Shareholders' Meeting of thepayment of the final dividend, which, in turn, includes the payout ofcapital gains obtained from the sale of the 27.7% stake in Auna. Thecapital gains were collected in 4Q05 and were therefore reflected infinancial leverage at December 31, 2005. However, it did not reflectthe distribution to shareholders, when will take place in 2006.

As a result of Gas Natural's take over bid for ENDESA, Standard &Poor's and Fitch Ratings decided to place ENDESA's credit rating underreview for a possible downgrade, while Moody's changed its ratingoutlook from stable to negative.

In all these cases, changes were due to the negative impact thetransaction would have, were it to go ahead, on the new company'sfinancial position. As a result, at May 16 2006, ENDESA's long-termdebt ratings are: Standard & Poor's, A, under review for a possibledowngrade; Moody's, A3, negative outlook, and Fitch, A+, under reviewfor a possible downgrade.

Disposal of Auna

1Q06 marked the end of the period for Auna shareholders toexercise their pre-emptive rights on the 5.01% stake ENDESA sold toDeutsche Bank on December 30, 2005.

After the end of this period, the sale to Deutsche Bank wasformalised. It now has the right to hold the shares. Accordingly, allthe conditions required by International Financial Reporting Standards(IFRS) - derecognition of the shares from ENDESA's balance sheet andthe recognition of the capital gain in its income statement - havebeen met.

Therefore, as indicated in ENDESA's consolidated financialstatements for the year ended December 31, 2005, in 1Q06 the Companyrecorded a capital of Euro 196 million (Euro 171 million after tax)for the sale of the 5.01% stake in Auna to Deutsche Bank.

Once the sale was completed, "Other businesses" has been removedfrom ENDESA's accounts, so in the rest of 2006, there will only bebooked this capital gain.

Real estate disposals: Bolonia Real Estate activity

The Euro 14 million real estate disposals made in 1Q06demonstrates the Company has made further progress in the divestmentplan committed in its Strategic Plan. ENDESA's target from real estatedisposals is to obtain Euro 250 million for the whole 2006. Among theprojects managed by Bolonia Real Estate, ENDESA's subsidiary managing140 million square meters, noteworthy is its active role in the UrbanDevelopment Plan taking place in Palma de Mallorca. It owns 187,000square meters of land to be built on, to be added to the 37,000 squaremeters already sold in this city in 2005.

PROGRESS IN THE STRATEGIC PLAN

The excellent results achieved by ENDESA in the first three monthsof the year leave it well on track to beat the targets included in itsStrategic Plan.

This performance extends the trend achieved in 2005, when theCompany also easily surpassed its targets.

The key financial targets in the Company's Strategic Plan andcomparison with the 1Q06 performance are explained below.

ENDESA's Strategic Plan

-- Compound annual net income growth in excess of 12%.

-- Compound annual EBITDA growth of between 10% and 11%.

-- Financial leverage below 140%.

On the basis of meeting these targets, ENDESA is to implement adividend policy which prioritises shareholder remuneration along thefollowing lines:

-- Growth in excess of 12% in dividends linked to ordinary activities, i.e., in line with expectations for net income growth.

-- Distribution of 100% of capital gains from disposals of non-core assets.

The implementation of this dividend policy entails thedistribution of over Euro 7,000 million of dividends to shareholdersover a five-year period.

1Q06 RESULTS SURPASSED THE TARGETS COMMITED IN THE 2004-2009STRATEGIC PLAN

A comparison of the results obtained by ENDESA in 1Q06 and themain targets of the Strategic Plan shows the following:

-- Net income growth of 87.9% in the first three months of 2006 compared with the 12% CAGR 2004-2009 target.

-- EBITDA growth of 31%, above the 10-11% CAGR target for the period mentioned.

-- Financial leverage at March 31, 2006 of 124.2%; i.e. 15.8 percentage points below the maximum 140% level defined in the Strategic Plan.

Meanwhile, in 1Q06 the Company disposed of Euro 393 million worthof non-core assets, obtained Euro 181 million of net capital gains,roughly 60% of the total net capital gains envisaged for 2006.

This large amount, coupled with the dividend paid out of profitfrom ordinary activities for the year, will help maintain a highreturn policy and meet the overall dividend target. Accordingly, inthe first two years of the Strategic Plan, shareholders have receivedroughly 60% of the more than Euro 7,000 million earmarked fordividends in the 2004-2009 period.

In sum, ENDESA's excellent set of interim results, achieveddespite the more stringent regulatory environment in Spain, leave theCompany on track to not only achieve, but surpass, the targets of theStrategic Plan.

RESULTS BY BUSINESS LINE:

BUSINESS IN SPAIN AND PORTUGAL

Net income up 49.5%

Net income from this business line was Euro 568 million in 1Q06,an increase of 49.5% on 1Q05 and equivalent to 54% to the Company'soverall bottom line.

EBITDA rose 25.9% to Euro 1,037 million and EBIT by 38.5% to Euro773 million.

In 1Q06, ENDESA recorded under revenues the amount correspondingto compensation for the non-mainland generation historical deficitcalculated in accordance with the Ministerial Orders passed on March30, 2006 which was above the amounts booked at December 31, 2005. ThisEuro 212 million of higher compensation was booked as revenues. AtDecember 31, 2005, these compensations earned Euro 31 million ofinterest, recognised as financial revenue. The impact of these amountson ENDESA's net income is Euro 212 million.

Key operating highlights

Maintaining a leadership position

ENDESA maintained its leading position in the Spanish electricitymarket in the first quarter this year.

The Company boasts a 38.5% market share in ordinary regimeelectricity generation, a 42.2% in share distribution, 49% in sales toderegulated customers and 41.6% in total sales to final customers.

Considerable progress in the New Capacity Plan

ENDESA continued to make progress throughout 1Q06 on its NewCapacity Plan.

During the period, work on the 400MW Cristobal Colon (Huelva) CCGTwas completed. The tests carried out in the first few months of theyear proved fully satisfactory.

In addition, construction continued on the 800 MW CCGT at AsPontes (La Coruna), while preparations were made to convert group 3 ofthis facility to imported coal.

In addition, the Company added 93 MW of capacity to itsnon-mainland systems and brought 46 MW of new renewable capacity onstream.

The 539 MW through to March 2006 represent 40.8% of plannedcapacity additions for the full year.

Strong growth in the Company's market

In 1Q06, ENDESA's total demand was 29,375 GWh. This figurerepresents growth of 2.9% compared to 1Q05.

The number of customers served by ENDESA in the regulated businessincreased by 61,984 through March.

In the deregulated market, ENDESA ended March with 1,038,215customers, 38.9% more than at end-March 2005. The Company's presencein this market provides a hedge against the volatility of pool prices.

Further improvement in quality of supply

The Quality Plan being implemented by ENDESA in the last few yearsenabled the Company to register a sharp improvement in its supplyquality in 1Q06, particularly noteworthy if we consider that this wasachieved in a scenario that featured sharp increases in thepeak-demand.

ENDESA's total system average interruption duration index (SAIDIor TIEPI) for 1Q06 was 35 minutes, 5.4% better than in 1Q05.

As for customer service, ENDESA's retention rate for customersswitching to the deregulated market was 95.8%, outperforming all itscompetitors and reflecting a high degree of loyalty towards theCompany.

Regulatory updates

Impact of Royal Decree Law 3/2006

Royal Decree Law 3/2006 entails the following changes to powergeneration revenues.

-- As from March 3, 2006, sales to the wholesale generation market that match purchases by a distributor belonging to the same group to be sold in the regulated market will be settled at a price set by the government based on market prices, which must be objective and transparent.

-- The Royal Decree Law sets the price provisionally at Euro 42.35 per MWh. ENDESA's accounts for 1Q06 must be drawn up based on this price. However, if generation costs remain at 1Q06 levels during the rest of the year, the final price will have to be higher, meaning that ENDESA's reported revenues and income will also be higher.

-- The impact on ENDESA's revenues in 1Q 06 of applying a price of Euro 42.35/MWh rather than the pool price, has amounted to Euro 43 million.

-- The amount finally recognised for each business group for financing the deficit in regulated revenues in 2006 will be subtracted from the value of the free CO2 emission rights received from during the period from January 1 to March 2, 2006.

-- Pending to the definition of the detailed norm which will explain how to make the calculation, ENDESA has opted to be conservative, calculating the proportional part of the period of freely allocated emission rights received in 2006 and assessing the value taking the average market price in the first two months of 2006. This methodology gives an amount of Euro 121 million, recognised as a decrease in revenues from generation sales and a decrease in the amount receivable to be recouped from the tariff deficit.

-- From March 3, 2006, revenues from power sales on the OMEL organised market at the established price by this market are minorized by the value of the freely allocated emission rights related to those revenues.

As some aspects of the new legislation are provisional, theaccounting entries at March 31, 2006 related to its application arelikewise provisional until the detailed norms are enacted and thecorresponding settlements are made.

Completion of the regulatory framework for non-mainland systemsensuring revenues from the generation business

On March 30, 2006 the Ministry of Industry, Tourism and Tradeapproved the Ministerial Orders which fully develops the Royal Decree1747/2003, which rules Spain non-mainland systems.

These orders establish the methodology for calculating regulatedremuneration on generation in these systems and, accordingly, thecompensation to be received by the companies operating in them.

Application of the orders gives rise to compensation of Euro 887million to ENDESA for the 2001-2005 period above the provisionalamounts envisaged in the subsequent Royal Decree tariffs of each year.To December 31, 2005, ENDESA's financial statements recognisedrevenues for this concept of Euro 644 million, recording the remainingEuro 243 million in 1Q06. Of this amount, Euro 212 million were bookedas revenues and the remainder, i.e. Euro 31 million, as financialrevenues as they correspond to interest accrued.

With the regulatory framework in place, non-mainland generationare guaranteed sufficient revenues going forward to meet the costs ofthe business and facilitate appropriate fuel price hedges, while atthe same time ensuring a reasonable return.

Noteworthy is the completion of the regulatory framework for thenon-mainland systems in line with the hypothesis considered under the2004-2009 Strategic Plan.

Sharp growth in sales: +25.9%

Sales from the business in Spain and Portugal totalled Euro 2,578million in 1Q06, a 25.9% increase compared to 1Q 05.

Growth was primarily due to the increase in sales prices to finalcustomers, to higher prices in the wholesale market in January andFebruary -before Royal Decree Law 3/2006 came into effect- and theimpact of the enactment of the Ministerial Orders regulating thecalculation of remuneration of non-mainland generation.

The increase in sales was enough to offset the sharp rise incosts, mainly fuel and energy purchases.

The increase in costs underpinned a 16.5% rise in averagegeneration pool prices. The high pool price impacted ENDESA's resultsin January and February. However, from March 3, 2006, following theapplication of Royal Decree Law 3/2006 discussed above, the pool pricehas not a significant impact on ENDESA's results, as the balancebetween the Company's output and sales means it sells a low volume ofelectricity to the pool.

However, the pool price will provide a benchmark for setting thefinal price for generation sales to regulated customers in areas whereENDESA distributes electricity. This price is provisionally Euro42.35/MWh.

The tariff deficit

Although the electricity tariff for 2006 is 4.48% higher, it isinsufficient to cover the system's entire costs, particularlygeneration costs, which include the pool price.

This leads to a deficit in revenues from regulated activities inthe sector, estimated at Euro 1,178 million, of which Euro 520 millioncorrespond to ENDESA.

Of this amount, Euro 399 million have been recorded as a financialasset, after subtracting the Euro 121 million corresponding to theprovisional valuation of the free CO2 emission rights allocated toENDESA in the first two months of the year as established by RoyalDecree Law 3/2006.

This is recognised as a financial asset because of the rightrecognised to the Company to recover the amount, even though the wayit will be recovered has yet to be regulated once the fiscal yearends.

The Euro 121 million contribution to cover the deficit notrecognised as a financial asset, have been booked as a decrease ingeneration revenues.

Had this Euro 399 million from the revenue deficit on regulatedactivities not been booked as a financial asset, revenues, EBITDA andEBIT would be that much lower and net income Euro 259 million lower.

We would also point out that in accordance with the CNE's latestsettlement, the portion of the regulated revenue deficit for 2005,which ENDESA must finance amounts to Euro 1,691 million, Euro 110million higher than in the 2005 financial statements. The amount ofthe 2005 deficit to be recouped increases by the same amount. Thischange does not affect ENDESA's FY2005 or 1Q06 results, as itcorresponds to an amount paid by the Company that it will recover infuture.

Revenues: up 32.9%

Revenues at this business unit totalled Euro 2,867 million in1Q06, up 32.9% on 1Q05.

Of this amount, sales accounted for Euro 2,578 million, 25.9%higher than in 1Q05.

compensation for non-mainland generation deficit calculated in
accordance with the Ministerial Orders passed on March 30 2006,
which was above the amounts recorded at December 31, 2005.
Stripping out this amount, revenues from the non-mainland supply
and generation businesses in 1Q06, calculated in accordance with
these Ministerial Orders, amount to Euro 415 million, 48.2% higher
than in 1Q05.

Mainland generation

Demand for electricity in the Spanish mainland system as a wholein 1Q06 grew by 2.3%. Ordinary regime output was 6.9% higher andrenewable/CHP generation 1.6%.

ENDESA's mainland electricity output totalled 20,008 GWh, 5.4%less than in 1Q05. Of this amount, 19,393 GWh corresponded toelectricity generated under the ordinary regime (-6.2%) and 615 GWhunder the renewable/CHP or special regime, up +31.1% compared to 1Q05.

The fall in ordinary regime generation was mostly due to higherhydro output by the system as a whole, to scheduled plant downtimesfor maintenance of some fossil fuel groups and ENDESA's priority onmargins over market share.

ENDESA's coal plants continued to play an important role inmeeting Spanish electricity demand in 1Q06. The utilisation rate atthese plants was 81.2% in response to grid requirements, proving that,in spite of the CCGT and wind farm capacity additions, coal plants arestill indispensable to meet the country's electricity requirements.Specifically, ENDESA's coal-fired plants covered 13.2% of mainlanddemand in the period.

Growth in sales

Sales to the Ordinary Regime totalled Euro 1,151 million throughMarch, 2.8% higher than the same period last year.

This amount includes sales made after March 3 to EndesaDistribucion to supply regulated customers in areas where ENDESAdistributes electricity, which were recognised taking a provisionalprice of Euro 42.35/MWh.

In accordance with Royal Decree Law 3/2006, to obtain this amountof sales, Euro 121 million corresponding to the provisional marketvalue of certain CO2 emission rights allocated freely were deductedfrom the settlement made by OMEL.

The average pool price in 1Q06 was Euro 63.48/MWh, 16.5% higherthan in 1Q05.

The negative impact on 1Q06 figures from selling the 2,609 GWhproduced in March, which were sold to regulated customers in the areaswhere ENDESA acts as a distributor, at the provisional price of Euro42.35/MWh as established in the Royal Decree Law was Euro 43 million.This impact is only temporary, as the final settlement price for theenergy has yet to be established.

ENDESA renewable/CHP generation

Special Regime companies fully consolidated by ENDESA produced 615GWh in 1Q06. This marked a 31.1% increase on 1Q05, despite thedisappointing wind energy conditions in the first two months of theyear. In addition, ENDESA has holdings in other Special Regimecompanies, which generated 953 GWh in the same period.

Revenues from sales of renewable/CHP energy generated byconsolidated companies totalled Euro 83 million, 124.3% more than in1Q05. This underpinned a 9.26% increase in EBITDA to Euro 52 millionand a 117.7% increase in EBIT to Euro 37 million.

Supply to deregulated customers

ENDESA had 1,038,215 deregulated customers at March 31, 2006. Ofthese, 976,695 corresponded to the mainland deregulated market, 58,557are from the non-mainland systems and 2,963 are from other Europeanderegulated markets.

ENDESA's sales to these customers totalled 9,606 GWh in the firstthree months of 2006, 10.5% more than in the same period of 2005. Ofthis amount, 8,476 GWh were sold on the Spanish deregulated market, anincrease of 10.7%, and 1,130 GWh on other deregulated Europeanmarkets, up 8.6%.

Revenues from supply to deregulated clients in Spain (excludedtolls paid to Endesa Distribucion) totalled Euro 452 million, a 23.2%increase on 1Q05. Of this amount, Euro 422 million corresponded to themainland deregulated market and Euro 30 million to the non-mainlandone.

Revenues from supply to deregulated European markets other thanSpain rose 27.3% to Euro 76 million, implying an average increase inprices of 27.3%.

Worth highlighting is the 10.9% year-on-year increase in theaverage selling price to final customers deriving from the Company'smore stringent and selective commercial policy.

Distribution

ENDESA distributed 29,375 GWh of electricity in the Spanish marketthrough March, 2.9% more than in the first three months of last year.

Revenues from regulated distribution activities totalled Euro 413million, up 4% on 1Q05.

ENDESA supplied 17,502 GWh to customers on the regulated Spanishmarket in the period, 5.5% more than in the same period last year.

Non-mainland generation

ENDESA's output in non-mainland systems rose 3.1% in 1Q06 to 3,456GWh, with sales surging 123.9% from the year-ago period to Euro 627million.

These sales include Euro 212 million of additional compensationsabove those recorded at December 31, 2005 for the non-mainland systems2001-2005 deficits as recognised in the Ministerial Orders of March30, arising from Royal Decree 1747/2003. Stripping out this amount,sales would have been Euro 415 million, a 48.2% increase.

Gas distribution and supply

ENDESA sold a total of 7,140 GWh of natural gas in 1Q06, 12.2%more than in the same period last year.

Of this amount, 6,739 GWh were sold through fully consolidatedcompanies, representing a 14.2% increase. And of these, 5,624 GWh weresold on the deregulated market (up +23.1% vs. 1Q 05) and 1,115 GWh onthe regulated market (down -16.2% vs. 1Q 05). ENDESA also sold 401 GWhon the regulated market through gas subsidiaries non-fullyconsolidated.

The 7,140 GWh sold in both the regulated and liberalized markets,together with the 5,209 GWh consumed in ENDESA's own generationplants, amount to a total of 12,349 GWh, implying a 10.8% marketshare.

Revenues from gas sales in the deregulated market in 1Q06 totalledEuro 140 million, representing growth of 40% on 1Q05. Revenues fromregulated gas distribution increased 9.1% to Euro 12 million.

Other operating revenues

Other operating revenues in 1Q06 came to Euro 289 million, Euro179 million more than in 1Q05.

This item includes Euro 239 million corresponding to 1Q06 portionof free CO2 emission rights allocated to ENDESA within the scope ofthe Spanish National Allocation Plan for emissions, which are recordedas revenue.

This figure is Euro 172 million higher than in 1Q05, mostlybecause of the higher value of the rights received in 2006. The higherrevenue is offset by the higher expense recorded for use of theemission rights.

Power purchases

Power purchases in the period rose 39.4% to Euro 301 million. Themain component of this line item relates to transactions on thewholesale generation market. This increase in power purchases islinked to the 16.5% rise in the average pool price and to higherpurchases on the market.

The balance relates to gas purchases to supply deregulatedcustomers, which rose as a result of the 40% increase in sales tothese customers and the increase in gas prices.

Fuel consumption

Fuel consumption amounted to Euro 562 million in the first quarterof 2006, an increase of 15.2% vs. the same period in 2005.

This increase is due to the generalised increase in raw materialsprices on international markets.

These higher costs were offset by the Company's proactive fuelprocurement policy, which resulted in below-market purchasing prices.

Compared to the estimated 22% increase in fuel costs by the restutilities in the mainland system, ENDESA's rose only by 5%. This hasconsiderably strengthened the Company's competitive position withrespect to price and generation mix.

Other supplies and services

Expenses under this line item totalled Euro 382 million, Euro 244million higher than in 1Q05.

This increase reflects the recognition of Euro 279 million ofexpenses in connection with rights acquired to cover the CO2 emissionsmade throughout the first quarter of the year, which totalled 12.7million tonnes: 9.5 million tonnes for the mainland production and 3.2million tonnes for non-mainland one. This cost was Euro 187 millionhigher than in 1Q05, mostly because of the higher value assigned tothe freely allocated emission rights in 2006 vs. 2005, as mentioned inthe section "Other operating expenses".

The net effect of revenues and expenses booked in 1Q06 to coverCO2 emissions was Euro 40 million, corresponding to an estimatedrights deficit of 1.8 million tonnes.

Personnel expenses

At March 31, 2006, the workforce in Spain and Portugal totalled12,711, a decline of 121 employees or 0.9% on the year before.

Personnel expenses rose 16.8% vs. 1Q05 to Euro 250 million.

These expenses include Euro 18 million corresponding to aprovision for headcount reduction, mainly related to the provision forthe early layoff of specific workforce groups, which will help theCompany achieved part of the cost reductions envisaged in theStrategic Plan.

Stripping out the impact of the net provisions for contingenciesrelated to the job losses both in 1Q05 and 1Q06, personnel expenses inthe first three months this year were only 3.6% high.

Net financial expenses: a decrease of 28.3%

ENDESA reported net financial expenses for the first quarter of2006 of Euro 79 million, 31.9% lower than in 1Q05.

Of this amount, Euro 81 million corresponded to net financialexpenses, 28.3% less than in the same period last year, and Euro 2million to exchange-rate gains.

Net financial expenses include revenue of Euro 31 millioncorresponding to the interest accrued at 31 December 2005 on thehigher compensations derived from the non-mainland generation deficitcalculated in accordance with the Ministerial Orders passed on March30, 2006.

When assessing financial results, the Euro 2,936 million financialassets corresponding to the tariff deficit and non-mainlandcompensation, both of which bear financial interest, must beconsidered.

Net financial debt in the Spain and Portugal business at March 31,2006 stood at Euro 11,602 million vs. Euro 11,461 million at December31, 2005. This slight increase is due to the Euro 666 million paid in1Q06 to financial the revenue shortfall from regulated activities.

Equity-accounted income

Equity-accounted income in the electricity business in Spain andPortugal totalled Euro 24 million. This amount includes, inter alia,the contribution from Nuclenor.

Asset disposals: Euro 14 million of capital gains

In 1Q06, ENDESA generated gross capital gains of Euro 14 millionon disposals of non-core assets -basically real estate- of itsbusiness in Spain and Portugal.

Cash flow from operating activities: Euro 728 million

Cash flow from operating activities from the Spanish andPortuguese business totalled Euro 728 million through March, anincrease of 35.1% on the same period last year.

Investments: 78.9% increase in new generation capacity and 38.4%increase in distribution to improve quality of service

Investments in Spain and Portugal in 1Q06 reached Euro 950million, 63% more than in the same period last year. Excluding thefinancing of the tariff deficit, the total was Euro 441 million, 45.5%higher than in 1Q05.

90.9% of total investment was spent on capex to develop or enhanceelectricity generation and distribution facilities.

The breakdown of capex reflects the considerable effort made bythe Company to improve service quality in Spain, with investment indistribution facilities accounting for 65.6% of the total. We alsohighlight the significant increase in capital expenditure to expandENDESA's generation capacity, above all on the construction theCristobol Colon (400 MW) and As Pontes (800 MW) CCGTs and capacityincreases in renewables.

BUSINESS IN EUROPE

Net income of Euro 118 million

Net income from the business in Europe rose 3.5% year-on-year toEuro 118 million.

This result does not reflect any capital gains from assetdisposals, unlike in 1Q05, when ENDESA booked Euro 36 million ofincome under this heading. Like-for-like (i.e. stripping out thecapital gains on the sale of assets in 1Q05), net income would havegrown 51.3%.

Solid growth projects

In 1Q06, Endesa Europa focused on two of its main strategictargets: consolidating its current position and seeking new growthopportunities.

On March 17, Endesa Europa signed an agreement to acquire 25.5% ofOLT Offshore LNG Toscana, S.P.A., the owner of the offshoreregasification terminal to be built off the coast of Livorno (Italy).Estimated investment amounts to Euro 400 million and authorisedregasification capacity is close to four billion cubic metres (bcm)per annum of which, under the terms of the agreements negotiated,Endesa Europa will control approximately two bcm per annum.

This project, together with ENDESA's project in the Gulf ofTrieste, guarantees competitive gas supplies for the Italian marketand increases the flexibility of ENDESA's fuel mix.

In addition, on March 27, Endesa Europa signed an agreement toacquire from the Merloni Group a 50% of MPE Energia S.R.L., a companythat sells energy and provides related services to final customers.

Concerning Endesa Italia, the construction on the two 400MW CCGTsat the Scandale plant (Calabria) is proceeding according to schedule.This project was acquired by a 50/50 joint venture between EndesaItalia and ASM Brescia at the end of December 2004.

In the first quarter of 2006, Endesa Italia distributed a Euro 176million dividend to shareholders, of which Euro 140.8 millioncorresponded to Endesa Europa.

Initiatives undertaken in the period at Snet fell under theauspices of its Industrial Plan, aimed at developing new capacity bymeans of the future optimisation of its current sites in order tobring total new capacity of 2,000 MW in CCGTs and 200 MW inrenewables/CHP on-stream. Within the scope of this plan, noteworthyinitiatives in 1Q06 include the adjudication to build a 10 MW windfarm at Lehaucourt (Picardy) at an estimated investment of Euro 10million.

Snet also made significant progress in its supply activitiesduring the period. It signed an agreement with the Frenchmultinational company Auchan (Alcampo) to supply 400 GWh of power in2006 and an agreement with SNCF (the French railway operator) tosupply 6,600 GWh in the period 2007-2011. The second contract enablesSnet to lock-in demand for a significant portion of its free capacityduring this period.

Finally, a Euro 59.7 million dividend payments to shareholders wasapproved at Snet's General Shareholders' Meeting held on March 1. Inlight of the Euro 21.2 million interim dividend already paid out, onMarch 9, Snet paid out a final dividend of Euro 38.5 million, of whichEuro 25 million corresponded to Endesa Europa.

Positive performance of Endesa Italia continues

Endesa Italia's revenues totalled Euro 809 million in 1Q06, up44.5%, due to a 9.5% increase in electricity sold, higher electricityprices in the Italian market and the fact that the Delibera 254 forunfair trade practices was not levied on the Company, allowing it torelease a Euro 26 million provision in previous years to 2005 revenue.

The Company generated a total of 7,619 GWh of electricity, anincrease of 1,538 GWh or 25.3% on 1Q05. Its market share in Italystood at 9.5%.

The generation structure of Endesa Italia in 1Q06 reflects ahigher percentage of fuel-oil production, up from 17.8% to 24.4%, as aresult of the application of extraordinary measures to reduce gasconsumption through March in order to guarantee supply availability.Although Endesa Italia's fuel costs increased by Euro 137 million in1Q06, this was far less than the increase in revenues due to higherelectricity prices triggered by the jump in fuel prices.

The Italian Government approved the National Allocation Plan (NAP)of greenhouse gas emission rights in the first quarter of 2006, whichhas been afterwards ratified by the Europeans Authorities. At the endof the 1Q 06, the formal constitution of the corresponding Registerwas still pending, which began to operate in April.

This NAP has allocated to Endesa Italia 33.9 million tonnes forthe period 2005-2007. However, as of March 31, 2006, the physicaldelivery of the company's rights was still pending -that is why theyhad not been booked as an intangible asset at the balance sheet close.

The income statement reflects the cost of the CO2 emission rightssolely on the basis of the estimated deficit since as the rights hadnot yet been delivered at March 31, 2006, neither the revenue nor theexpense associated with the free allocation of emission rights hasbeen booked, which will have a neutral impact on earnings.

Significant earnings improvement at Snet

Earnings at Snet improved significantly in 1Q06, with EBITDAgrowing 30.2% to Euro 56 million and EBIT by 93.3% to Euro 29 millionvs. 1Q05.

The French generator recorded revenues of Euro 333 million in thefirst three months of the year, a 48.7% increase vs. the same periodin 2005. This is mainly the result of the 34.4% increase in output to4,324 GWh.

Variable costs increased Euro 96 million basically as a result ofthe Euro 29 million increase in fuel costs, the Euro 48 million risein energy purchases and greater expense of Euro 25 million associatedwith emission rights, primarily due to their higher unit cost in 1Q06vs. 1Q05, although the impact is offset by a similar increase inrevenues from the free allocation of emission rights.

European debt: reduction of Euro 51 million

Net financial debt at ENDESA's business in Europe stood at Euro1,235 million at 1Q06, a reduction of Euro 51 million, or 4%, over thedebt at year-end.

Net financial results amounted to an expense of Euro 11 million in1Q06, Euro 4 million less than in 1Q05.

Cash flow: Euro 208 million

Operating cash flow generated by this business stood at Euro 208million, compared to Euro 200 million in 1Q05.

Investments: Euro 42 million

Investments in 1Q06 in the European business totalled Euro 42million. Of this, Euro 32 million were capex and the remaining Euro 8million were accounted for by Endesa Italia and Snet.

Financial investments for the period totalled Euro 10 millionincluding Euro 2 million for the acquisition of 25.5% of OLT OffshoreLNG Toscana, S.P.A. and Euro 3 million for the acquisition of 50% ofMPE Energia S.R.L.

BUSINESS IN LATIN AMERICA

Excellent bottom line growth: net income up 170.8%

Net income at ENDESA's Latin American business totalled Euro 195million in 1Q06, an increase of Euro 123 million, or 170.8% on 1Q05and equivalent to 18.35% to the Company's overall net income.

The results includes a positive impact of Euro 101 million, net ofminority interests, from the lower tax charge derived form theElesur-Chilectra merger approved at each companies' respective GeneralShareholders' Meetings held in March 2006.

This performance reflects the consolidation of the favourableeconomic trends witnessed in the region in 2005, marked by highergrowth and increased exchange rate stability in ENDESA's operatingmarkets, as well as the success of the management measures implementedby its subsidiaries throughout the region.

Highlights in the period

Growth in volume sales in generation and distribution

The favourable economic environment pushed demand sharply, 5.8%increase on average and above 4% in all the countries where ENDESA hassubsidiaries. Noteworthy is the increase in demand in Peru (8.2%),Argentina (7.3%) and Chile (5.5%).

Higher demand led ENDESA's subsidiaries to record totalelectricity sales of 14,363 GWh, up 6.5% vs. 1Q05, with sharpincreases in Peru (+9.7%) and Brazil (+7.5%).

ENDESA generated 14,656 GWh in the region in 1Q06, 0.7% more thanin 1Q05. Output increased the most in Peru (+6.2%) in response to thesharp increase in demand and in Colombia (+4.2%), primarily due tohigher rainfall in the region where the Betania plant is located andhigher Emgesa's thermal output to make up for the rain shortfall inthe Guavio region.

The fall in output in Argentina (-2.9%) is due to the fact thehigher hydro production at the El Chocon plant was not enough tooffset the fall in thermal generation, due to maintenance downtimes atthe CCGTs and lower dispatch from the Costanera plant; and in Brazil(-4.3%) primarily to lower output at the Fortaleza plant as a resultof restrictions on gas supply which more than offset the increase inoutput at Cachoeira.

Finally, output in Chile grew 1.6%, where the Company has showedsignificant improvement in costs thanks to a better generation mix asa result of higher rainfall during the period.

Improvement in generation and distribution margins

Growth in demand, tighter reserve margins and the bettergeneration mix at ENDESA's subsidiaries caused the unit margin ofgeneration companies to increase by 19.9% in 1Q06 vs. 1Q05 to US$ 25.9per MWh produced.

Generation margins expanded significantly in all countries whereENDESA operates with the exception of Argentina, which declined due tolower capacity payments on export contracts.

In distribution, operating margins were considerably boosted byimproved pass-through of generation costs achieved in tariff revisionsover recent months and operating efficiency improvements, leading to aconsiderable improvement in these companies' operating indicators. Theunit margin of distribution stood at $34.8/MWh, up by 23%.

Reduction in distribution losses

Energy distribution losses were 11.3% in 1Q06, 0.5 percentagepoints lower than in 1Q05.

Losses were contained in all countries, notably in Argentina andBrazil, where the percentage of losses was cut by 0.7 and 0.6percentage points, respectively.

These improvements in the distribution network management are theresult of a continuing technological innovation policy, as it has beendemonstrated by the positive progress made in Brazil through thedevelopment and implantation of the Ampla new grid.

New capacity development

In 1Q06, Endesa Chile continued work on the CCGT San Isidro II,which will have a total installed capacity of 377MW, as well as thePalmucho hydroelectric plant, with planned capacity of 32MW. Bothprojects are located in Chile.

In Peru, progress was made on the construction of Etevensa II(second CCGT being build) and on the conversion of Etevensa I into aCCGT. Both projects are slated for completion this year, bringing anadditional 172 MW of new capacity on-stream and making the generationmix significantly more competitive.

In Colombia, Emgesa completed the acquisition of the 186 MWTermocartagena thermal plant.

Endesa Eco commenced work on the 9 MW Canela wind farm and on theOjos de Agua mini hydro station, also with capacity of 9 MW.

Finally, in 2Q06 ENDESA Chile signed an agreement with electricityprovider Colbun -controlled by the Matte Group, one of Chile's leadingbusiness conglomerates- for its inclusion in the Aysen Project, whichentails the construction of four hydro plants with total installedcapacity of 2,430 MW.

Optimisation of organisational structure

1Q06 featured the completion of the organisational restructuringin Brazil (incorporation of the Brazilian holding company, EndesaBrasil), Peru (Etevensa-Edegel merger) and Chile (Chilectra-Elesurmerger).

-- ENDESA contributed all the assets it held directly and indirectly in Brazil to ENDESA Brasil. The incorporation of this holding company will simplify the organisational structure in Brazil, resulting in the generation of more stable local cash flows, improve third-party financing and reinforce the Company's position in Brazil vis-a-vis new growth opportunities.

-- On January 17, 2006, the shareholders of Edegel and Etevensa ratified the resolutions taken by their respective Boards in November 2005 to merge Etevensa and Edegel. On April 12, this operation was approved by the corresponding local anti-trust authorities. This transaction results in a more balanced overall generation mix (51% hydro and 49% thermal), which will reduce earnings volatility as a result of variations in rainfall, create synergies from overlapping overhead costs, strengthen its financial structure, generate economies of scale and increase shareholder liquidity.

-- The Boards of Directors of Chilectra and Elesur approved the merger of the two companies on March 31. This transaction will eliminate holding companies, reduce overhead costs, and optimize tax charges.

Regulatory update

Regulatory highlights in 1Q06:

-- In Brazil the tariffs applied to Ampla and Coelce were increased by 2.9% and 10.01%, respectively.

-- In relation to the Bilateral Agreement between Argentina and Brazil, the Argentina Secretary for Energy issued a resolution on February 3 permitting companies with export contracts to renegotiate them. The aim of the resolution is to encourage imports to meet demand.

-- On February 15, the Argentine Senate ratified the agreement between UNIREN and Edesur. Now the President must sign the resolution for its definitive approval. This is expected to be given within the next two months.

-- A trust has been set up to enable the Argentine generation companies under the Foninvemem agreement - awarded with 1,600 MW of CCGTs -to obtain the necessary administrative and operating resources.

-- In January, the Colombian electricity regulator issued a resolution modifying the calculation to limit generation market share, providing ENDESA's subsidiaries with access to higher market volume.

Generation and transmission

Chile

Energy generated in 1Q06 rose 1.6% to 4,369 GWh. Output wasdampened by natural gas supply problems, which were offset by theimproved generation mix thanks to higher hydro generation.

This, together with the favourable trend in the Chilean pesorelative to the euro and higher prices drove EBITDA from ENDESA'ssubsidiaries to Euro 133 million and EBIT to 104 million, increases of87.3% and 131.1%, respectively, vs. 1Q05.

Colombia

A 4.2% increase in total electricity generation output togetherwith the Colombian peso appreciation against the euro underpinnedincreases of 16.7% and 18.6% in EBITDA and EBIT, respectively, to Euro63 million and EBIT to 51 million.

Brazil - Generation

Total electricity generation declined by 4.3%, as the growth inactivity at Cachoeira Dourada was not enough to make up for gas supplyproblems.

However, this, coupled with favourable exchange-rate, helpedcushion the impact of the increase in fuel consumption, giving EBITDAin 1Q06 of Euro 34 million and EBIT of 29 million, increases of 6.3%and 3.6%, respectively, vs. 1Q05.

Brazil - Transmission

The difficulties in exporting electricity from Argentina to Brazildue to gas supply restrictions continued, having a negative impact onresults of this interconnection. EBIT in 1Q06 was Euro 2 million, Euro15 million lower than in 1Q05.

Peru

Generation sales reached Euro 76 million in 1Q06, up 18.8% on1Q05, mainly thanks to higher prices, which offset the Euro 11 millionincrease in fuel costs.

EBITDA was Euro 45 million, 7.1% higher than in 1Q05, while EBITstood at Euro 34 million, up 6.3% on the same period last year.

Argentina - Generation

Total electricity generation fell 2.9% due to lower output at theCostanera plant.

Gas supply problems continued to trigger increases in fuel costs(+23.4%) due to the need to generate power using more expensive liquidfuels. This undermined margins. As a result, EBITDA in 1Q06 totalledEuro 34 million, down 15% vs. 1Q05, while EBIT fell 28.6% to Euro 25million.

Distribution

Chile

The 52.6% increase in revenues, boosted by exchange rates andhigher volumes, offset the squeeze on margins caused by the latesttariff revision.

EBITDA rose 35.1% to Euro 50 million EBIT by 34.4% to Euro 43million compared to 1Q05.

Colombia

EBITDA of the distribution business was Euro 63 million, 28.6%higher than in 1Q05, while EBIT stood at Euro 48 million, up 54.8%.

These rises were due to an 18.1% increase in revenues to Euro 163million, enough to cover the higher costs of buying electricity and astronger Colombian peso versus the euro.

Brazil

Distribution sales came to Euro 421 million in 1Q06, a 56.5%increase on 1Q05.

The rise resulted from wider margins as consequence of theenhanced pass-through of generation prices to customers and, to alesser extent, higher volume sales (+7.5%).

This increase in electricity sales clearly offset the highercosts, boosting EBITDA in 1Q06 by 101.7% to Euro 117 million and EBITby 120.0% to Euro 99 million compared to 1Q05.

Peru

EBITDA from distribution amounted to Euro 22 million in 1Q06, up22.2% on 1Q05, mainly due to higher sales (+15.5%) which more thanoffset higher costs. EBIT advanced 27.3% from the same period lastyear, to Euro 14 million.

Argentina

Revenues from distribution stood at Euro 100 million in 1Q06, up23.5% year-over-year, outpacing the 17% increase in procurements coststo give EBITDA of Euro 25 million and EBIT of Euro 18 million,increases of 13.6% and 12.5%, respectively.

Financial results: Euro 124 million

Financial results for the business in Latin America reflected aloss of Euro 124 million in the first quarter of 2006, Euro 53 millionmore than in 1Q05.

Net exchange-rate gains were Euro 34 million lower, down from Euro50 million in 1Q05 to Euro 16 million this quarter. Net interestexpense totalled Euro 140 million, Euro 19 million or 15.7% higherthan the year-ago period.

This increase is mainly due to the higher costs driven byreadjusted pension funds, the early pay off of loans, and the exchangerate effect on financial expenses. These debt financial expensesexpressed in local currencies remain stable compared to the previousyear.

Net debt at ENDESA's Latin American business at March 31, 2006stood at Euro 5,923 million, representing a reduction of Euro 186million since the start of the year. This decrease is fundamentallydue to the performance of the euro against the currencies in whichENDESA's Latin American subsidiaries' debt is denominated, accountingfor Euro 122 million of the reduction.

Worth pointing out is that in the second quarter this year, therating agency Fitch has upgraded its ratings for Enersis and EndesaChile from BBB- to BBB, stable outlook.

Tax

The merger between the Chilean companies Chilectra and Elesur hasled to a lower tax change, for a total recognised amount of Euro 170million (Euro 101 million after minority interests).

Cash flow: up 26%

Cash flow generated by ENDESA's business in Latin America totalledEuro 363 million in 1Q06, an increase of 26% with respect to 1Q05.

Investments: Euro 220 million

Investment in Latin America stood at Euro 220 million in 1Q06. Ofthis amount, Euro 193 million corresponded to capex.
