Blog: California’s hydroelectric generation affected by historic drought
[A]s a result of this year’s harsh drought conditions, we expect hydroelectric generation in California to be lower in 2021 than it has been in recent years. In the first four months of 2021, hydroelectric generation in California was 37% less than in the same four months in 2020 and 71% less than during those months in 2019. According to our Short-Term Energy Outlook, hydroelectric generation in California this year will be 19% less than last year, decreasing from 16.8 million megawatthours (MWh) in 2020 to 13.6 million MWh in 2021.
