Ref.: Essential Fact:: New Distribution Rates

Dear Sir,

In accordance with Articles 9 and 10.2 of Law 18,045, in addition to the General Rules No. 30 and No. 210, both issued by the Superintendency, and with the authority vested on me, I hereby inform you of the following Essential Fact.

In 2008, pursuant to the General Law of Electric Services, the process of fixing distribution rates began, affecting among other companies, our subsidiary Chilectra S.A.

This process ended on Wednesday, April 8, 2009, when the Ministry of Economy, Development and Reconstruction published in the Official Gazette, the Decree No. 385, that “SETS RATE FORMULAS APPLICABLE TO SUPPLY SUBJECT TO REGULATED PRICES, AS LISTED, DELIVERED BY THE DISTRIBUTION CONCESSIONARIES INDICATED.” Rates published as a result of this process will be effective as of November 4, 2008 until November 2012.

As consequence of the application of the mentioned Decree, the negative effects over Enersis S.A. future results are estimated on 14,100 million of Chilean pesos per annum after taxes, which correspond to a decrease of the income of our subsidiary Chilectra S.A., that is estimated in about 17,144 million of Chilean pesos annually.

Yours sincerely,

Ignacio Antoñanzas Alvear
Chief Executive Officer
