One of the challenges of renewable energy is dealing with intermittency and providing power when it is needed. In this piece it is pointed out that in the Southwest there is a partial mismatch. It leads to a rapid ramp in power demands over a relatively shore 1 hour period. This is hard for utilities to manage, particularly when they are adding lots of renewables which, for the most part are not dispatchable.
The Solana Generating station has an approach that addresses this nicely.Solana is a solar plant with molten salt storage allowing it to continue to generate electricity after dark.
“it will also be able to continue providing much of that power for six hours after sunset thanks to an innovative heat-storage system”
