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 May 27, 2020, the Board of the Company approved the early disconnection of Bocamina I and Bocamina II coal-fired power plants, both located in the district of Coronel, with a gross installed capacity of 128 MW and 350 MW, respectively (hereinafter “Bocamina I” and “Bocamina II” respectively). All the aforementioned is subject to the corresponding authorizations of the National Energy Commission (“CNE” in Spanish).

If the aforementioned authorizations from the CNE are obtained, Enel Generación will permanently withdraw and disconnect these two power plants from the National Electric System, establishing as deadlines for these milestones, December 31, 2020 for Bocamina I and May 31, 2022 for Bocamina II. All the abovementioned is subject to the authorization provided for in the General Law of Electrical Services, and to the applicable procedure for the power plants disconnection that is included in the Decarbonization Agreement between the Ministry of Energy and Enel Generación Chile S.A. subscribed on June 4, 2019.

As a sign of the Company's commitment to tackle climate change, Enel Generación has determined to anticipate the date of disconnection and withdrawal of Bocamina I and II, initially planned for no later than December 31, 2023 and December 31, 2040, respectively, according to the significant event issued by the Company on June 04, 2019. Regarding the Bocamina I power plant, no significant effects in 2020 results are generated, considering that during 2019 an impairment loss was recorded regarding this power plant, which reduced its book value to its recoverable value.

Consequently, Enel Generación should record an impairment loss related to the Bocamina II power plant, which will affect the Company's 2020 net income for an approximate amount of Ch$ 502,000 million (approximately USD 626 million).

Sincerely,

Michele Siciliano
