ENERSIS

ANNOUNCES CONSOLIDATED RESULTS

FOR THE PERIOD ENDED ON MARCH 31^st,, 2011

Highlights for the Period

Summary

Ø On April 25, Moody's upgraded the international senior unsecured debt rating of Enersis and our subsidiary Endesa Chile to Baa2 from Baa3, with stable outlook. According to the agency, the upgrade of both companies “largely reflects each issuer’s strong consolidated credit metrics”, and also factors that “internal cash flow generation will remain robust and that dividend policy will continue to be conservative”.

Ø Within this financial context, it’s important to highlight the successful issuance on the international markets of an unsecured bond issued by Emgesa, our Colombian generation subsidiary, for an amount equivalent to US$ 400 million in Colombian pesos.

Ø The first quarter of this year confirmed the growth in electricity demand experienced in the markets where we operate, of which we can highlight the strong increase in demand observed in our Chilean and Peruvian operations, where demand for electricity grew 9.1% and 7.7% respectively.

Ø This relevant increase in demand is mostly attributable to the stronger economic activity in these markets, in every segment.

Ø The boosted activity, according to consensus forecasts, will remain during 2011, based on projections for GDP growth, of 6.8% in Peru, 6.0% in Chile, 5.8% in Argentina, 4.6% in Colombia and 4.1% in Brazil.

Ø Linked to the above mentioned it is important to highlight that a proper commercial policy and also the availability of our thermal capacity allowed us to satisfy the growing demand, although Chile is facing one of the more severe droughts in the last 60 years.

Ø In this context, it is important to highlight the recovery of our coal-fired power plant Bocamina I, damaged by the last year earthquake. This positive achievement allowed us to provide the country with a more secure and stable source of energy during a dry year.

Ø A well diversified mix of assets, contributed to balance the structure of our EBITDA, as follows,

§ Generation and Transmission
§ Distribution 53%
47%

Ø Our Distribution client´s base increased by more than 372,000 new customers, confirming the high stability coming from the natural growth of our business.

Ø Operating income of the period totaled Ch$ 350,715 million, equivalent to a 9% decrease compared with the same period of 2010.

	PRESS RELEASE 1Q 2011

Distribution Business

Consolidated figures for the Distribution Businesses are detailed as follows:

Ø Operating Revenues increased 4.1%, amounting to Ch$ 1,075,926 million.

Ø Operating Costs reached Ch$ 921,954 million, which represent an 8.8% increase compared with 2010.

Ø EBITDA totaled Ch$ 205,985 million, a 17.7% decrease when compared with 2010, mainly due to the decrease in results from our Colombian and Brazilian operations, partially offset by better results from our Chilean and Peruvian operations.

Factors that influenced these results, on a country by country basis, are the following:

In Chile, EBITDA increased Ch$ 6,975 million, which is mainly the result of:

Ø A better sales margin mainly related to the strong demand observed during the quarter.

Ø An increase in revenues from ancillary services, mainly related to the higher economic activity prevailing during the first quarter of the year 2011 when compared with 2010.

In Peru, EBITDA increased Ch$ 340 million, as a result of:

Ø Higher physical sales by 7.7%, which resulted in increased revenues from energy sales.

Ø The increase in revenues from ancillary services.

Ø The latter was partially offset by higher energy losses by 0.3 pp.

In Argentina, EBITDA decreased Ch$ 8,311 million, as result of:

Ø A lower purchase/sales margin measured in Argentinean pesos.

Ø An increase in operational costs, mainly related to higher costs due an increase in wages.

Ø The above mentioned was partially offset by an increase in physical sales, mainly explained by the higher demand related to the increase in economic activity in the country.

In Brazil, EBITDA decreased Ch$ 26,092 million, as a result of:

Ø A decrease in sales margin on both Ampla and Coelce, due to a worse sales margin mainly related to a reduced tariff in Ampla related to a lower energy cost recognized, and a worse sales mix at the level of Coelce.

Ø The above was partially offset by an increase in physical sales at the level of Ampla.

In Colombia, EBITDA decreased Ch$ 17,343 million, mainly due to

Ø The effect of the government reform on the Equity Tax, which resulted in registering as of January 1^st 2011 the entire amount to be paid for this concept within the period 2011-2014.

Ø This one-time effect completely offset the better sales margins recorded during the period, resulting from higher physical sales and lower energy looses.

	PRESS RELEASE 1Q 2011

Generation and Transmission Business

Ø Consolidated physical sales rose by 3.8% to 15,672 GWh, increasing mainly in Colombia, Peru and Argentina. As a result of these higher physical sales and higher average sales prices, sales revenues increased by 8.6% when compared to the first quarter of 2010, reaching Ch$ 630,888 million.

Ø Operating Revenues increased 9.5%, when compared with same period 2010, amounting to Ch$ 639,046 million.

Ø Operating Costs reached Ch$ 438,281 million, which represent a 14.3% increase compared with 2010, as a result of higher energy and fuel purchase costs in our Chilean, Brazilian and Argentinean operations.

Ø EBITDA totaled Ch$ 231,710 million, an 11.5% decrease when compared with 2010.

Ø Consolidated hydroelectric generation decrease 2.7%, mainly explained by reductions in Brazil, Chile and Argentina, partially compensated by increases in Colombia and Peru.

Factors that influenced these results, on a country by country basis, are the following:

In Peru, EBITDA increased by Ch$ 2.870 million due to:

Ø Higher energy sales revenues of Ch$ 5,364 million, resulting from a higher sales volume related to the increasing energy demand observed in the country.

Ø Lower energy purchase costs of Ch$ 1,904 million.

Ø Partially compensated by increased fuel costs of Ch$ 2,036 million.

In Chile, EBITDA fell by Ch$ 4,048 million mainly due to:

Ø Higher energy purchase costs by Ch$ 43,316 million.

Ø Higher transportation costs of Ch$ 3,484 million.

Ø Partially compensated by higher energy sales revenues of Ch$ 31,873 million.

In Brazil, EBITDA fell by Ch$ 5,253 million mainly due to:

Ø Higher energy purchase costs of approximately Ch$ 14,756 million, mainly at the level of Endesa Fortaleza.

Ø Partially compensated by higher energy sales revenues of Ch$ 12,353 million.

In Argentina, EBITDA fell by Ch$ 6,162 million due to:

Ø Higher fuel costs of Ch$ 11,720 million.

Ø Partially compensated by higher energy sales revenues of Ch$ 10,173 million.

In Colombia, EBITDA decreased Ch$ 17,601 million, mainly due to

Ø The effect of the government reform on the Equity Tax, which resulted in registering as of January 1st 2011 the entire amount to be paid for this concept within the period 2011-2014.

Ø This one-time effect completely offset the better sales margins recorded during the period, resulting from better hydrology and higher physical sales.

Pg. 3

	PRESS RELEASE 1Q 2011

Financial Summary

Ø The average interest rate increased, from 7.4% up to 8.5%, mainly because of inflationary effects.

Ø Liquidity, a key consideration in our financial management, continues to be in a very solid position, as shown below:

· Cash and cash equivalents amount to US$ 2,080 million in the aggregate for Enersis Consolidated.

· Committed long term credit lines for US$ 975 million in the aggregate for Enersis Consolidated, of which US$ 268 million are due on the short term.

· Non-committed credit lines for US$ 1,866 million available in the aggregate for Enersis Consolidated.

Ø Within this context, it’s important to highlight the successful issuance on the international markets of an unsecured bond in local currency by Emgesa, our Colombian generation subsidiary, for an amount equivalent to US$ 400 million. This breaking-through deal, the first bond issued in local currency on the international markets by a Colombian private company, was rated as Investment Grade by Fitch and Standard and Poor’s, ratified our criteria of allowing subsidiaries to be financially healthy by its own merits.

Ø Coverage and Protection: In order to mitigate exchange rate and interest rate risks, Enersis has established strict internal rules to protect our cash flows and balance sheet from variations in these variables.

· Our exchange rate policy is based on cash flows and it strives to maintain a balance between US dollar indexed flows, and assets and liabilities in such currency. In addition to this policy, we have contracted Cross Currency Swaps for a total amount of US$ 1,437 million and Forwards, for US$ 329 million.

· In order to reduce volatility on financial results due to changes in market interest rates, we seek to maintain an adequate balance upon our debt structures. Thus, we have contracted Interest Rate Swaps for US$ 354 million.

Market Summary

Risk Rating Classification Information

Enersis’ international and domestic credit ratings have been upgraded in 2010, due to Company’s improvements in its liquidity position and lower leverage. The positive perspectives on operational and credit profile of Enersis have been reflected in the upgrades received by Fitch Ratings and Standard & Poor’s for our international ratings and by Feller Rate and Fitch Rating for our domestic rating.

Current ratings are further supported by our well diversified asset portfolio, strong credit metrics, adequate debt structure and solid liquidity. Enersis’ geographic diversification through Latin America provides us a natural hedge against different regulations and weather conditions. Most of our operating subsidiaries are financially strong and have leading market positions in the countries where they operate.

Additionally, on April 25, 2011, Moody's upgraded the international senior unsecured rating of Enersis from Baa3 to Baa2 with stable outlook. According to the agency, this improvement reflects Enersis’ long established and strong financial position.

The current risk classifications are:

Ø International Ratings:

Enersis	S&P	Moody’s	Fitch
Corporate	BBB+ / Stable	Baa2 / Stable	BBB+ / Stable

Ø Domestic Ratings (for securities issued in Chile):

Enersis	Feller Rate	Fitch
Shares	1^st Class Level 1	1^stClass Level 1
Bonds	AA / Stable	AA / Stable

Net Financial Income

The Company’s Net Financial Income as of March 31, 2011 was negative Ch$ 69,391 million, representing an improvement of 16.4% over the same period last year. The latter is mainly explained by: (i) higher Financial Income by Ch$ 16.926 million equivalent to Ch$ 13,644 million, as a consequence of an increase in the amount of financial incomes due to the Brazilian pension plan by Ch$ 11,267 million and higher cash deposits during the period, (ii) lower expenses related to Foreign Currency Exchange Differences by Ch$ 10,616 million, primarily linked to Chile, Argentina and Brazil.

The latter was partially offset by: (i) higher Financial Expenses by Ch$ 11,321 million, due to an increase of average interest rates during this period and an update of pension funds (ii)higher costs related to indexed liabilities by Ch$ 2,577 million, linked to the negative effect of inflation over U.F. denominated debt in Chile. U.F., a non-transaction currency linked to the inflation in Chile, increased its value by 0.6%

Taxes

Income Tax increase by Ch$ 3,312 million at the end of March 2011. The latter is mostly explained by decreases in: Ampla by Ch$ 6,459 million, Coelce by Ch$ 5,150 million, Endesa Chile by Ch$ 4,816 million, Edesur by Ch$ 2,941 million and Pangue by Ch$1,465 million. The latter was partially offset by increases in Cien by Ch$ 5,843 million, Emgesa by Ch$ 2,582 million, Pehuenche by Ch$ 2,380 million Codensa by Ch$ 1,218 million, Edegel by Ch$ 1,162 million and Chilectra by Ch$ 720 million.

Total Assets increased Ch$ 352,637 million, mainly due to:

Ø Ch$ 375,596 million increase in Non-Current Assets, equal to a 3.5%, as a result of:

v Ch$ 198,533 increase in Property, Plant and Equipment, explained by the conversion effect to Chilean pesos from subsidiaries’ financial statements by Ch$ 171,436 million, and additions for the period in approximately Ch$ 112,682 million.

v Ch$ 89,629 million increase in Intangible Assets other than Goodwill, due exchange rates variations.

v Ch$ 46,848 million increase in Trade Accounts Receivables and Other Receivables, mainly due to the increase in Ampla and Coelce, by the appliance of IFRIC 12 interpretation, regarding Service Conversion Arrangements.

v Ch$ 27,489 million increase in Goodwill linked to fluctuation of local currency against Chilean peso.

v Ch$ 12,002 million increase in Other Non-Current Financial Assets, mainly explained by an increase of liens in Ampla and Coelce.

The above was partially offset by:

Ø Decrease in Current Assets by Ch$ 22,960 million, which equals to a 1.0% decrease, mainly due to:

v Ch$ 73,893 million decrease in Non-Current Assets Classified as Held for Sell, related to the selling process of the former subsidiaries CAM and Synapsis, executed during this quarter.

	PRESS RELEASE 1Q 2011

v Ch$ 12,334 million decrease in Other Current Financial Assets, due to lower liens delivered by Ampla.

v Ch$ 35,825 million increase in Cash and Cash Equivalent, primarily explained by increases in Time Deposits at Emgesa by Ch$ 68,952 million; Chilectra by Ch$ 46,119 million due to increases in repos (repurchase agreements); Cachoeira Dourada by Ch$ 26,382 million and Fortaleza by Ch$ 14,532, and Edegel by Ch$ 10,535 million all explained by an increase in Time Deposits.

Book Value and Economic Value of Assets

Regarding the more important assets, the following should be mentioned:

Properties, Plants and Equipment are valued at their purchase cost, net of the corresponding accumulated depreciation and impairment loss they have been subject to. Properties, Plants and Equipment, net of their residual value, if applicable, are linearly by distributing the cost of their different elements along the estimated years of useful life, which is the period that the companies expect to use them. The useful life is reviewed regularly.

The capital gain (lower investments or goodwill value) generated by consolidation represents the acquisition cost surplus on the Group’s share in terms of the reasonable value of assets and liabilities, including the identifiable contingent liabilities of a Subsidiary at the time of acquisition.

Capital gain is not amortized. Instead, at the closing of each accounting period an assessment is made of whether any impairment has occurred during the period that could reduce its recoverable value to an amount below the registered net cost, proceeding in this event to make a timely impairment adjustment (See Note 3.e to the Consolidated Financial Statements).

Throughout the fiscal year and in particular at the date of closing, an assessment is made as to any indication of possible loss due to the impairment of any asset. In the event of any such indication, an estimate of the recoverable sum of said asset is made to determine, if applicable, the depreciated amount. If this involves identifiable assets that do not originate independent cash flows, the recoverability of the Cash Generating Unit that the asset belongs to is estimated, understanding as such the smaller Group of identifiable assets that generate independent cash incomes.

Assets expressed in foreign currency are submitted at the prevalent exchange rate at the closing of the period.

Notes and accounts receivable from related companies are classified according to their short and long term maturities. These operations are adjusted according to prevalent market equity conditions.

In summary, assets are valued according to the International Financial Reporting Standards, whose criteria are expressed in Note 3 of the Consolidated Financial Statements.

Liquidity, a key consideration in our financial management, continues to be in a very solid position. As of March 2011, liquidity reached 1.07 times, increasing 0.10 times, equivalent to a 10.3% when compared to December 2010. Enersis has a sound financial profile and ample access to credit markets. In fact, the Company has been serving its debt maturities with own generated resources, with an appropriate maturity schedule.

The Company has credit lines with financial institutions, as described below:

Ø Cash and cash equivalents amount to US$ 2,080 million in the aggregate for Enersis Consolidated.

Ø Committed long term credit lines for US$ 975 million in the aggregate for Enersis Consolidated, of which US$ 268 million are due on the short term.

Ø Non-committed credit lines for US$ 1,866 million available in the aggregate for Enersis Consolidated.

Leverage ratio, as of March 31, 2011, reached 0.97, showing a decrease of 3.0% as of December 2010.

Financial Expenses Coverage reached 3.9 times, a decrease of 0.87 times or 18.0% drop from the ratio registered on equal period the precedent year. This is mainly the result of the EBITDA decrease during this period, and the increase in Financial Expenses.

Operating Income over Operating Revenues profitability decreased 14.5%, reaching a 22.3% as of March 2011.

The annual ROE of the Parent Company reached 13.1%, a decrease of 27.8% from the registered as of March 2010. This decrease is derived from the lower results for the period, together with an increase in shareholders’ equity.

Annual ROA reached 8.0% in March 2011, a decrease of 12.4% from the registered as of March 2010, reflecting the decrease in the present period’s results partially offset by a decrease in Total Assets.

PRESS RELEASE
1Q 2011

The Principal Risks associated to the activities of the Enersis Group

Commercial and Regulatory Risk

The Group’s activities are subject to a broad range of governmental standards and environmental regulations. Any modification of such standards and regulations may affect the Group’s activities, economic situation and operating results.

The Group’s distribution activity is subject to a wide range of rules regarding tariffs and other issues that govern their activities in each of the countries where it operates and which could modify distribution subsidiaries operating results.

The Group’s generation activity is subject to existing hydrological and weather conditions in the geographic zones in which the Group’s hydroelectric generating plants are located. Commercial policies have been planned in order to moderate the possible impact of changes in these variables.

Group’s activities are subject a wide of environmental regulation that Enersis fulfills constantly. Modifications applied on such regulations may affect the operations, economic condition or the results of these operations.

Enersis and its operating subsidiaries are subject to environmental regulations which, among other things, require the company to conduct environmental impact studies for future projects, obtaining permits, licenses and other authorizations and the fulfillment of all requirements of those licenses, permits and norms. As any other regulated company, Enersis cannot guarantee:

· The approval from regulators of environmental impact studies.

· That public opposition may not cause delays or modifications to any proposed project and

· That laws or regulations may not change or be interpreted in a manner that could adversely affect the operations or the plans for companies in which Enersis or its subsidiaries hold investments.

Interest Rate Risk

Interest rate variations modify the fair value of those assets and liabilities that accrue a fixed interest rate, as well as the future flows of assets and liabilities pegged to a variable interest rate.

In compliance with our current interest rate hedging policy, the portion of fixed and/or hedged debt to the total net debt was 54% as of March 31, 2011 on a consolidated basis.

Depending on the Group’s estimates and debt structure objectives, hedging transactions take place contracting derivatives that mitigate these risks.

Exchange Rate Risk

The exchange rate risks are mainly related to the following transactions:

Foreign currency debts contracted by Group’s companies.
Payments to be made on international markets for the acquisition of projects related materials.
Group companies’ incomes directly linked to the evolution of the dollar, and
Incoming cash flows from our subsidiaries abroad exposed to exchange rate fluctuations.

Pg. 26

	PRESS RELEASE 1Q 2011

In order to mitigate exchange rate risks, Enersis’ exchange rate hedging policy is based on cash flows and it strives to maintain a balance between dollar indexed flows and the asset and liability levels in such currency. Currency swaps and exchange rate forwards are the instruments currently used in compliance with this policy. Likewise, the policy strives to refinance debts in each company’s functional currency.

Commodities Risk

Enersis is exposed to the price fluctuation risk on some commodities, basically through fuel purchases for the electricity generation and also energy transactions (buying and/or selling) in the local markets.

In order to reduce risks in extreme drought conditions, the company has designed a trading policy that defines sales commitment levels consistent with its generating plants’ firm energy in a dry year, including risk mitigation clauses in some unregulated clients’ contracts.

In view of the operative conditions faced by the electricity generation market in Chile, like extreme drought and rising oil prices, the company has decided to take a hedge to place a cap on the Brent price for consumption projected for the period April-July 2011. Market and operative conditions will be constantly analyzed to adjust the volume hedged or take new hedges for the following months.

Liquidity Risk

In engaging committed long term credit facilities and short term financial investments the Group maintains a consistent liquidity policy, for the amounts required to support projected needs for the period, contingent with the situation and the expectations in the debt and capital markets.

As of March 31, 2011, the Enersis Group held liquidity in the amount of Ch$ 997,179,889 thousand in cash and cash equivalent and Ch$ 339,048,000 thousand in committed long term credit lines. As of December 31^st, 2010, the Enersis Group held liquidity in the amount of Ch$ 961,355,037 thousand in cash and cash equivalent and Ch$ 242,750,000 thousand in committed long term credit lines.

Credit Risk

Credit risk in accounts receivable, originating from trading activities, has been historically very limited given that the short term collection conditions with customers doesn’t allow them to individually accumulate significant amounts. Additionally, in the case of the so-called “unregulated clients” of our electricity generation and distribution business, a formal procedure is applied to control the credit risk, using a systematic evaluation of our counterparties, index definition and credit risk factors by virtue of which the contracts are approved or additional guarantee requirements are defined.

Furthermore, in our electricity generating business line, in the event of non-payment, some countries allow power supply cut-offs, and in almost all contracts a lack of payment is established as cause for contract termination. For this purpose, credit risks are constantly monitored and the maximum amounts exposed to payment risks are measured, which are limited.

In turn, in our electricity distribution business line, the energy supply cut-off is a power held by our companies in case of default by our customers, applied in accordance with the applicable regulation in each country, enabling the credit risk evaluation and control process, which is also limited.

Surplus cash flow investments are placed in prime national and foreign financial entities (with an investment grade equivalent risk rating) with limits set for each entity.

Pg. 27

	PRESS RELEASE 1Q 2011

In the selection of banks for investment, are considered those that hold two investment grade classifications, according to the three main international risk agencies (Moody’s, S&P and Fitch Ratings).

Positions are backed up by treasury bonds from the country of operations and instruments issued by the most reputable banks, favoring, wherever possible, the first ones.

Derivatives are engaged with highly solvent entities; about 90% of operations are conducted with entities that hold an A or higher rating.

Risk Measurement

The Enersis Group measures the Value at Risk (VaR) of its debt and financial derivatives positions in order to guarantee that the risk taken by the company remains consistent with the risk exposure defined by Management, thus restricting the volatility of its financial results.

The positions portfolio used in the calculations of the current Value at Risk is comprised of debt and financial derivatives.

The calculated Value at Risk represents the possible value loss of the aforementioned positions portfolio over one day time horizon with 95% of confidence.

The volatility of the risk variables that affect the value of the positions portfolio has been studied, including:

The U.S. dollar Libor interest rate.
The usual banking local indexes for debts, taking into account the different currencies our companies operate under, and
The exchange rates of the different currencies involved in the calculation.

The calculation of VaR is based on generating possible future scenarios (at one day) of market values (both spot and term) for the risk variables, using Monte Carlo simulations. The number of scenarios generated ensures compliance with the simulation convergence criteria. A matrix of volatilities and correlations between the various risk variables calculated based on the historical values of the logarithmic price return, has been applied to simulate the future price scenario.

Once the price scenarios have been obtained, the fair value of the portfolio is calculated using such scenarios, obtaining a distribution of possible values at one day. The one-day 95% confidence VaR number is calculated as the 5% percentile of the potential increases in the fair value of the portfolio in one day.

The various debt positions and financial derivatives included in the calculation have been valued consistently using the financial capital calculation methodology reported to Management.

Other Risks

A portion of Enersis and Endesa Chile’s debt is subject to cross default provisions. If certain defaults in debt of certain specific subsidiaries are not remedied within specified grace periods, a cross default could affect Endesa Chile and Enersis, and under certain scenarios, debts at the holding company level could be accelerated.

Nonpayment – after any applicable grace period – of the debts of Enersis and Endesa Chile, or their so-called Relevant Subsidiaries, with an individual principal amount outstanding in excess of US$ 50 million dollars (or its equivalent in other currencies), and with a missed payment also in excess of US$ 50 million dollars, could give rise to a cross default of several bank revolving debt facilities at the Endesa

Chile and Enersis levels. Furthermore, some of these debt facilities are also subject to cross acceleration provisions in the event of a default in other Relevant Subsidiary debt, for reasons other than payment default, for events such as bankruptcy, insolvency proceedings, and materially adverse governmental or legal actions, in all cases for amounts in excess of US$ 50 million dollars.

	PRESS RELEASE 1Q 2011

Similarly, nonpayment – after any given applicable grace period - of the debts of these companies or any of their Chilean subsidiaries, in single indebtedness in default with a principal in excess of US$ 30 million dollars, could potentially give rise to a cross default of Enersis and Endesa Chile Yankee bonds.

There are no clauses in the credit agreements by which changes in the corporate or debt classification of these companies from risk classification agencies could trigger prepayments. Nevertheless, a modification in the Standard & Poor’s (S&P) debt risk classification in foreign currency could trigger a change in the margin applicable to determine the interest rate, in the credit loans executed in 2004 and 2006, and in local credit lines executed in 2009.

Endesa Costanera

The Operating Income reached Ch$ 6,097 million during the first quarter 2011, increasing by 7.4% when compared to the same period in 2010. This is mainly explained by Ch$ 13,622 million of larger revenues related to energy sales, which were partially compensated by an increase of Ch$ 11,720 million in fuel costs. It is important to highlight that Operating Revenues increased by 25.3%, supported by a 17.2% rise in physical sales and an 11.5% increase on the average sale price, measured in local currency.

The effect of converting the financial statements from the Argentine peso to the Chilean peso in both periods produces a reduction in Chilean pesos of 9.8% as of March 2011, with respect to March 2010.

Operating Income reached Ch$ 5,362 million, decreasing 42.6% when compared to first quarter 2010. The latter is mainly explained by lower Operating Revenues for Ch$ 3,442 million, related to a decrease in physical sales by 24.6%. This is linked to poorer hydrological conditions, leading to a generation of energy 34.7% lower when compared to first quarter 2010. Additionally, during the period El Chocón experienced higher costs related to energy purchases and tolls.

Operating Income decreased Ch$ 8,000 million, mainly due to a lower purchase/sales margin measured in Argentinean pesos, which was partially offset by a 0.7% increase in physical sales.

On the other hand, operational costs increased due to higher personnel wages, linked to the inflation that the country is experiencing.

Energy losses remained at 10.5%, the same level when compared to 2010. The customer base increased by 40,000 new clients, surpassing the 2.3 million clients served in the concession area.

Operating Income amounted to Ch$ 47,868 million, a 20.4% decrease when compared to first quarter 2010. The decrease is mostly explained by a lower purchase/sales margin and higher operating costs, especially related to external services.

The above was partially offset by a 4.6% increase in sales volume. It is worth mentioning the 1.2p decrease in energy losses during the period, which is the outcome of the application in full force of advanced and technology-based solutions for controlling non-technical losses.

Chilean Operations

The Operating Income of our Chilean operations reached Ch$ 94,732 million, result that almost suffered no variations when compared to the same period of the previous year.

The Operating Revenues increased due to a 15% rise on average prices, partially offset by a decrease in physical sales. This effect is mostly explained by lower sales in the spot market, linked to the poorer hydrology persistent in the country. Despite of the latter, higher sales in the regulated and non-regulated markets were registered, mainly explained by the economic recovery of Chile. It is important to mention that regulated and non-regulated customers showed an important increase in consumption when compared to the first quarter 2010, period that was affected by an earthquake in February 2010.

Additionally, the Operating Income was also affected by an increase of 27.2% for Procurement and Services, due to higher energy purchases and transport costs.

Chilectra

Operating Income amounted to Ch$ 30,079 million, showing an increase of 28.9% when compared to the period ended on March 31, 2010.

The increase is explained mainly due to better sales margin related to electricity business line, associated to a higher demand during the first quarter. Additionally, revenues from ancillary services also increased, explained by the lower comparison base when judged against 2010, especially regarding major clients and the effects post-earthquake.

The latter was partially offset by an increase in personnel wages.

Energy losses reached 5.7%. The customer base increased by 27,000 new clients, reaching 1.6 million clients served in the concession area.

The Operating Income reached Ch$ 27,913 million, 36.7% lower when compared to first quarter 2010. The main factor in this result was the effect of the government reform on the Equity Tax, which resulted in registering as of January 1^st 2011 the entire amount to be paid for this concept within the period 2011-2014. This one-time effect completely offset the better sales margins recorded during the period, as a consequence of better hydrological conditions and higher physical sales.

The effect of translating the financial statements from the Colombian peso to the Chilean peso in both periods produces an increase in Chilean pesos of 3.7% as of March 2011, with respect to March 2010.

Operating Income registered Ch$ 23,295 million, an increase of 18.2% with respect to the same period in 2010. The latter is mainly explained by a Ch$ 5,364 million increase in energy sales that relied on a 17.1% increase in physical sales. Another positive effect was the decrease in energy purchases that represented Ch $ 1,904 million lower expenses.

The above was partially offset by an increase in fuel costs, due to a higher generation of electricity based on thermal facilities and also to higher transportation costs.

The effect of translating the financial statements from the Peruvian sol to the Chilean peso in both periods produces a decrease in Chilean pesos of 4.7% as of March 2011, with respect to March 2010.

Operating Income reached Ch$16,690 million, representing a 2.4% increase when compared to first quarter 2010. The aforementioned is explained by a 7.7% rose in sales volume, and the increase in revenues from ancillary services. The latter was partially offset by a lower purchase/sales margin by 1.4%.

Energy losses reached 8.3%. The customer base increased by 42,000 new clients, surpassing the 1.1 million clients served in the concession area.

The effect of translating the financial statements from the Peruvian sol to the Chilean peso in both periods produces a decrease in Chilean pesos of 4.7% as of March 2011, with respect to March 2010.
