Drought Has Big Impact on California Power Market
Rain and snow has returned to California, ending the record-setting drought with record-setting precipitation.
The drought led to forest fires, dead orchards, and brown lawns. It also took a big bite out of ratepayers’ wallets and increased global warming emissions, due to the loss of low-cost, zero-emission hydropower.
In a study released April 26 by Peter Gleick—a noted water expert at the Pacific Institute in Oakland—researchers found that lower hydropower production cost California ratepayers almost $ 2.5 billion in higher power prices, and may have raised power sector carbon dioxide emissions 10%, due to increased output from gas-fired generators (see Figure 2). Gleick’s team used data through September 2016 to calculate the figures.

California has 14 GW of hydro capacity, with little growth in recent decades due to environmental, economic, and political constraints. While hydro typically supplies about 18% of California’s power, the drought dropped production to as low as 7% in 2015, the driest year of the drought.…
