SAO PAULO (S&P Global Ratings) Aug. 4, 2021--S&P Global Ratings said today that it maintains its 2021 EBITDA estimate for Enel Chile S.A. (BBB+/Stable/--) at $1.1 billion - $1.2 billion. This is despite the company's weaker-than-expected results in the first half of the year, mainly due to higher purchases of energy to meet its power purchase agreements. Electricity spot prices rose to $75 per megawatt hour (MWh) in the first half of 2021 from $46 per MWh in the same period of 2020. This was the result of dry conditions in Chile, scarce availability of natural gas coming from Argentina, and higher prices for liquefied natural gas. We expect the company's renewable energy facility of 800 MW - 820 MW
