Yes, there's no plan to resolve that as far as I know. The interconnects are meant to mitigate it a bit (i.e. import cheap green power from other countries when the winds not blowing, export it when it is blowing), but most of the plan is that there needs to be enough gas electricity generation for when there's zero solar and zero wind.
Grid scale storage on the order of days isn't really viable yet.
- martinald 3y agoMy personal guess is something like hydrogen will take this place eventually. In the not so distant future I think we will see a lot of sharply negative pricing on windy days, given that we will probably have ~70GW of wind capacity installed for perhaps 50GW of demand by 2030. Then on non windy days (especially at night with no solar), somewhat higher prices - not sure how high but there is going to be a big delta between the two. That means there will be a lot of aribitrage to be had and money to be made to store and shift that power. My guess is H2 will work quite well for this, as even if it's really quite inefficient the fact your input power is free/negative negates a lot of that. It really will come down to how cheap hydrogen electrolyzers can get.
