Ref.: MATERIAL INFORMATION

Dear Sir,

In accordance with clauses 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 under the powers conferred to me, I report to you the following material information:

The Decree No. 320, of the Ministry of Economy, Development and Reconstruction that establishes the sub-transmission tariffs that apply to our 99.09% subsidiary, Chilectra S.A., has been published on the Official Gazette, on January 9, 2009, reason why they will apply since January 14, 2009.

As consequence of the application of the mentioned Decree, the negative effect over Enersis S.A. future results are estimated on 43 billion Chilean pesos per annum after taxes, which correspond to a decrease of the income of our subsidiary Chilectra S.A. In present days market conditions, such decrease is estimated in about 52 billion Chilean pesos annually, before taxes.

Finally, we inform you that once Decree’s tariffs are effective, Chilectra S.A. will reverse provisions by 54.5 billion Chilean pesos net of taxes.

Yours sincerely,

Ignacio Antoñanzas Alvear
Chief Executive Officer
