Increasing Renewables Leads to Seasonal Storage Needs
CALIFORNIA WIND AND SOLAR CURTAILMENTS
HIT RECORD HIGH IN MARCH 2021
CALIFORNIA SURPLUS AND DEFICIT PATTERNS
UNDER A 100% RENEWABLE ENERGY SCENARIO
At just 30% renewable integration, peak
monthly curtailment exceeds 300,000 MWh
Renewable Energy Surplus
Renewable Energy Deficit

Seasonal surplus and deficits signal need for long-
duration energy storage “beyond the duck curve”
