	Buenos Aires, Argentina, May 11, 2007 – Empresa Distribuidora y Comercializadora Norte S.A. (NYSE: EDN; Buenos Aires Stock Exchange: EDN) (“EDENOR” or “the Company”), Argentina’s largest electricity distributor, today announced its results for the three month period ended March 31, 2007 (first quarter of 2007). All figures are stated in Argentine Pesos and have been prepared in accordance with Argentine GAAP.
	1Q07 Highlights
	•	Net Sales increased 89.6% to Ps. 628.4 million in the first quarter of 2007, compared to Ps.331.5 million in the first quarter of 2006, mainly due to the recording of the retroactive portion of the tariff increase charged to our non-residential customers for the period from November 1, 2005 through January 31, 2007, which amounts in aggregate to Ps. 218.6 million. This retroactive amount will be collected from our customers in 55 monthly installments beginning in February 2007 . Excluding this effect, net sales would have amounted to Ps. 409.8 million in the first quarter of 2007, with an increase of 23.6%, or Ps. 78.3 million, compared to the same period of 2006. This increase is due mainly to the fact that we began charging our non-residential customers the new tariffs ( adjusted by the November 2005 - May 2006 Cost Monitoring Mechanism, CMM) on February 1, 2007, as well as to an increase in volume of energy sold compared to the first quarter of 2006.
		On January 30, 2007, the ENRE formally approved a new tariff schedule reflecting a 28% increase, plus the CMM in the distribution margins (Aggregated Distribution Value or “VAD”) charged to non-residential customers as per the Adjustment Agreement, bringing our average tariff to Ps. 0.093 per KWh in the first quarter of 2007, compared to Ps.0.082 per KWh in the same period 2006 .
		Additionally, the application of the CMM represented an 8.032% increase of our VAD, which combined with the 28% increase, resulted in an overall 38.3% increase in our VAD compared to the same period of 2006.
	•	Volume of Energy Sold increased 9.0% to 4,390.7 GWh in the first quarter of 2007, compared to 4,027.1GWh in the first quarter of 2006.This increase was due mainly to a 6.2% increase in the average GWh consumption per customer and a 2.8% increase in the number of customers.

First Quarter 2007 Page 2 of 12

• Gross Margin increased 186.5% to Ps. 414.0 million in the first quarter of 2007, compared to Ps. 144.5 million in the same period of 2006.This increase is also largely due to the recording of the retroactive portion of the tariff increase under the new tariff structure. Without taking this effect into account, our gross margin would have been Ps. 195.4 in the first quarter of 2007.

• Net Operating Income increased significantly to Ps. 268.4 million for the three months ended March 31, 2007, compared to Ps. 11.9 million in the same period of 2006. In the first quarter of 2007, net operating income was mainly affected by the recording of the retroactive adjustment (Ps.218.6 million); without that effect, the net operating income for the first quarter of 2007 would have amounted to Ps. 49.8 million (an increase of 318.5 % vs. the first quarter of 2006)

• Net Income reached Ps. 106.8 million in the first quarter of 2007, compared to Ps.440.4 million in the first quarter of 2006. In the first quarter of 2007, net income was positively affected by the recording of the retroactive portion of the tariff increase; which was partially offset by the adjustment to present value of this retroactive amount and certain trade receivables and the adjustment to present value of restructured debt. In the first quarter of 2006, net income was positively affected by the gain resulting from our debt restructuring, including the adjustment to present value of the restructured debt (Ps. 284.8 million) and the recognition of the partial reversal of the valuation allowance of our net deferred tax assets (Ps. 193.5 million). Excluding all of these items, we would have recorded net income before income tax of Ps. 7.4 million in the first quarter of 2007, compared to a net loss of Ps. 37.9 million in the first quarter of 2006.

Comments from the Chief Executive Officer

Alejandro Macfarlane, the Company’s Chief Executive Officer, stated, “I am very pleased to present our results of operation for the first time as a publicly-traded company. The success of our initial public offering last month, reflected in an over subscription and growing share price, demonstrate the interest in our company, sector and country by the global capital markets.

Edenor’s strong first quarter results reflect the 28% VAD increase plus the CMM ratified in January for our non-residential customers, as well as improved efficiency in our operation and distribution.

Lastly, the new timeline for the integral tariff revision announced last week by the government confirm our outlook for a revised tariff structure in 2008, which, at a minimum, will maintain our current distribution margins following the increases granted under the Adjustment Agreement, including all CMM adjustments.”

	*        In millions of Argentine Pesos
(1)	For the three months of 2007 includes the effect of the retroactive tariff increase charged to our non-residential customers for the period from November 1, 2005 through January 31, 2007, which amounts to Ps. 218.6 million.

Net sales

Our net sales increased Ps. 296.9 million to Ps. 628.4 million in the first quarter of 2007 from Ps. 331.5 million in the first quarter of 2006; this variation is significantly affected by the recognition, during the first quarter of 2007, of the retroactive tariff adjustment from November 1, 2005 through January 31, 2007 resulting in a positive impact of Ps. 218.6 million. Net energy sales represented approximately 98.8% of our net sales in the first quarter of 2007, compared to 97.6% in the first quarter of 2006. Late payment charges, pole leases and connection charges represented the balance. Without considering the retroactive effect, net sales would have amounted to Ps. 409.8 million in the first quarter of 2007, with an increase of 23.6%, or Ps. 78.3 million, compared to the same period of 2006.

Energy sales increased Ps. 295.2 million, to Ps. 625.5 million in the first quarter of 2007 from Ps. 330.3 million in the first quarter of 2006, primarily as the result of the full accrual of the retroactive adjustment on the VAD (28% + CMM). The increase without considering this effect was of Ps. 76.6 million. The interim tariff increase began to be billed in February 1, 2007, reflecting a 28% increase in the VAD charged to our non-residential customers. Additionally, the regulator (ENRE) applied the CMM for the six months period between November 2005 and May 2006. This represented an 8.032% increase of our VAD, variation which when compounded with the 28% increase, resulted in an overall 38.3% increase in the VAD.

Regarding GWh sold, the period shows a 9.0% increase (4,390.7 GWh in the three months ended March 31, 2007 from 4,027.1GWh in the three months ended March 31, 2006). The increase in volume in the first quarter of 2007 compared to the same period in 2006 is attributable to:

- a 6.2% increase in the average GWh consumption per customer; and

- a 2.8% increase in the number of our customers.

Electricity purchases

Our electricity purchases increased 14.6% to Ps. 214.3 million in the first quarter of 2007 from Ps. 187.0 million in the first quarter of 2006, primarily due to a 12.6% increase in the volume of electricity (4,066.7 GWh in the first quarter of 2007 from 3,611.4 GWh in first quarter of 2006) resulting from an increase in demand, which we believe was attributable to an improvement in macroeconomic conditions in Argentina and to a shift by a number of our wheeling system customers (for whom we do not purchase energy) to the industrial category of customers (507 wheeling system customers in the first quarter of 2007 vs. 777 for the

First Quarter 2007 Page 4 of 12

first quarter of 2006). Total energy demand (including wheeling system demand) increased 8.5% in the first quarter of 2007 .

Our energy losses decreased to 9.3 % in the first quarter 2007 , compared to 9.8 % in the first quarter 2006.

Gross margin

Edenor’s gross margin increased significantly (186.5%) to Ps. 414.0 million in the first quarter of 2007 from Ps. 144.5 million in the first quarter of 2006. This increase is substantially affected by the recording in the first quarter of 2007 of the retroactive adjustment (from November 1, 2005 through January 31, 2007) of the tariff increase to our non residential customers (amounting to Ps. 218.6 million).

Without this effect, our gross profit would have amounted to Ps. 195.4, representing an increase of 35.2% over the same period of 2006.

Transmission and distribution expenses

Transmission and distribution expenses increased 15.0% to Ps. 98.9 million in the first quarter of 2007 from Ps. 86.0 million in the first quarter of 2006, mainly due to a Ps.6.3 million (30.1%) increase in salaries and social security taxes attributable to an increase in compensation and, to a lesser extent, an increase in the number of employees. Also due to price and activity increases in our contractors, we experienced a Ps. 4.5 million (39.8%) variation.

The percentages on revenues for 2007 are calculated on the basis of net sales excluding the retroactive VAD difference (a basis of Ps. 409.8 million).

Based on this analysis, our transmission and distribution expenses represented 24.1% of our revenues excluding the retroactive adjustment in the first quarter of 2007 compared to 25.8% in the same period of 2006.

Administrative expenses

Our administrative expenses include, among others, expenses associated with accounting, payroll administration, personnel training and systems maintenance and operation. Administrative expenses increased 11.0% to Ps. 26.3 million in first quarter of 2007 from Ps. 23.7 million in the first quarter of 2006, primarily as a result of:

- a Ps. 2.8 million (215.4%) increase in advertising expenses (including institutional relations, radio advertising and community service programs);

- a Ps. 0.7 million (25.9%) increase in computer services due mainly to the full effect of the renewal of our software licenses during 2006;

- a Ps. 0.6 million (8.4%) increase in salaries and social security taxes attributable to an increase in compensation.

The percentages on revenues for 2007 are calculated on the basis of net sales excluding the retroactive adjustment (of Ps. 409.8 million).

Administrative expenses represented 6.4% of our revenues excluding the retroactive adjustment in the first quarter of 2007 compared to 7.1% in the same period of 2006.

First Quarter 2007 Page 5 of 12

Selling expenses

Our selling expenses include expenses related to services to customers at our commercial offices, billing, invoice mailing, collection, and collection procedures, as well as allowances for doubtful accounts.

Selling expenses decreased 10.5% to Ps. 20.5 million in the first quarter of 2007 from Ps. 22.9 million in the first quarter of 2006, primarily as a result of a Ps. 5.3 million (96.4%) decrease in our allowance for doubtful accounts attributable to a favorable evolution of past due balances of customers. This was partly offset by increases of Ps. 0.5 million (8.8%) in outsourcing attributable to a price increase in outsourcing services contracts and of Ps. 0.8 million (17.8%) in salaries and social security taxes attributable to an increase in compensation and, to a lesser extent, an increase in the number of employees.

The percentages of revenues for 2007 are calculated on the basis of net sales excluding the retroactive adjustment (of Ps. 409.8 million).

Selling expenses represented 5.0% of our revenues excluding the retroactive adjustment in the first quarter of 2007 compared to 6.9% in the same period of 2006.

Net operating (loss) income

Net operating income increased significantly from Ps. 11.9 million in the first quarter of 2006 to Ps. 268.4 million in the same period of 2007, basically due to the aforementioned recording in the first quarter of 2007 of the retroactive adjustment. Excluding the effect of the retroactive portion of this increase, our net operating income for the first quarter of 2007 would have amounted to Ps. 49.8 million an increase of 318.5% compared to the first quarter of 2006.

Adjustment to present value of the retroactive tariff increase arising from the application of the new electricity rate schedule and of the Payment Plan Agreement with the Province of Bs.As.

The retroactive portion of the tariff increase, which amounts in aggregate to Ps. 218.6 million, will be billed and collected in 55 equal and consecutive monthly installments beginning in February 2007. In addition the amounts due under the Payment Plan of the Framework Agreement signed with the Province of Buenos Aires will be collected in 18 installments starting in January 2007. As required by Argentine GAAP, we account for these long term trade receivable at their present value, which we calculate at a discount rate of 10%. We have recorded a loss of Ps. 41.2 million in the three months ended March 31, 2007 as adjustment to present value of these two described receivables.

Adjustment to present value of new notes

We recorded a gain of Ps. 102.5 million in the first quarter of 2006, as a result of the adjustment to present value of payments due on our new debt instruments issued in our debt restructuring. In the first quarter of 2007, this gain is being partially offset, and thus we have recorded a loss of Ps. 15.1 million for this concept.

Other income (expenses), net

Other income (expenses), net, includes principally voluntary retirements and terminations, severance payments, revenues from outsourcing services we provide to third parties, net revenues or expenses from technical transportation services between electricity distribution companies and accrual for lawsuits. We recorded other expenses, net, of Ps. 6.4 million in the first quarter of 2007, compared to other income, net,

First Quarter 2007 Page 6 of 12

of Ps. 2.6 million in the first quarter of 2006. In the first quarter of 2006 we registered one-time gains such as recovery of supplies from third parties, which more than offset an increase in voluntary retirements and terminations.

Income tax

We recorded a tax charge of Ps. 63.0 million in the first quarter of 2007, compared to a benefit of Ps. 193.5 million in the first quarter of 2006.

The benefit in the first quarter of 2006 was due to the partial reversal of the valuation allowance of our net deferred tax assets mainly due to the fact that our management estimated that tax loss carry-forwards would be partially offset against future taxable income as a result of the then anticipated increase in our distribution margins, which at March 31, 2006 our management considered probable, and the effect of the gain on the debt restructuring recorded during that three-months period.

We recorded a tax charge of Ps. 63.0 million in the first quarter of 2007 due to a significant increase in our taxable income in this period, which allowed us to partially offset our tax loss carry-forwards recognized as an asset in 2006 .

Net income (loss)

We recorded net income of Ps. 106.8 million for the first quarter of 2007, compared to net income of Ps. 440.4 million for the first quarter of 2006. In the first quarter of 2007, net income was positively affected by the recording of the retroactive portion of the tariff increase; which was partially offset by the adjustment to present value of this retroactive amount and certain trade receivables and the adjustment to present value of restructured debt. In the first quarter of 2006, net income was positively affected by the gain resulting from our debt restructuring, including the adjustment to present value of the restructured debt (Ps. 284.8 million) and the recognition of the partial reversal of the valuation allowance of our net deferred tax assets (Ps. 193.5 million).Excluding all of these extraordinary items, we would have recorded net income of Ps. 7.4 million in the first quarter of 2007, compared to a net loss of Ps. 37.9 million in the first quarter of 2006.
