California drought leads to less hydropower, increased natural gas generation

The drought in California continues to increase in severity since California’s governor declared a state of drought emergency in January 2014. As of September 30, 58% of the state was classified as experiencing exceptional drought, the most intense drought category. These dry conditions limit hydropower generation, requiring generation from other sources to make up for the shortfall.

California’s drought, which began in 2011, has resulted in a significant decline in hydropower generation. On average, hydropower accounted for 20% of California’s in-state generation during the first six months of each year from 2004 to 2013. During the first half of 2014, however, hydropower accounted for only 10% of California’s total generation. Monthly hydropower generation in 2014 has fallen well below the 10-year range for each individual
