Plenty of snow in the Sierra and lots of rain just about everywhere else in California have helped alleviate drought conditions across the state. But there’s also another positive byproduct of the wet winter — a likely boost in the amount of hydroelectricity in California’s energy mix. “I’m looking at the reservoirs in the state and I see almost all of them at the historical average in terms of storage,” said Ghassan Alqaser, chief of the State Water Project Power and Risk Office at the California Department of Water Resources. “With that, we expect an above average hydro year.”
