Ref.: SIGNIFICANT EVENT

Dear Sir,

In accordance with articles 9 and 10 under Chilean Securities Market Law N° 18,045, and as established under Chilean General Norm N°30 of the Financial Market Commission (“CMF” in Spanish), and as duly authorized on behalf of Enel Generación Chile S.A. (“Enel Generación” or the “Company”), I hereby inform you as significant event that on July 27, 2020, the Board of the Company unanimously approved the update of both schedule and budget for the works of Los Cóndores Project (the “Project”) indicating a completion term foreseen for the last quarter of year 2023, followed by the commissioning and commercial operation of the generation units of the Project, with a total investment value of US$ 1,152 million.

Los Cóndores Project was informed to the Financial Market Commission through a significant event on April 1, 2014 and updated through a significant event on September 14, 2018.

The direct financial effects implying an increased amount up to US$ 195 million are related to future disbursements for the construction and completion of Los Cóndores Project, not being possible to determine at this date the financial effect of the longer operational start-up term, which will depend, among others, on the future price of the marginal cost, the price of the current contracts, the energy and power demand, maintenance and dispatch of other units of the system managed by the National Electric Coordinator, the exchange rate and the price of fuels.

Sincerely,

Michele Siciliano
