The authors link two widely used regional planning models, WEAP and LEAP, to study the impact of rising climate variability on water and electricity use in Sacramento, California. Historical data, combined with the current energy and water system configuration, were used to assess the implications of changes in temperature and precipitation.
Climate simulations suggest that electricity imports to the region would increase during hot dry spells, when regional power production is most constrained. In particular, regional imports of electricity would increase over 35% in hot dry years, assuming a 4°C increase in average temperature and a 25% decrease in average precipitation.
