Seems like a great time and place for the iron air batteries that are getting deployed now (Form Energy). Even in the US, without Dunkelflaute, these 100:1 energy:power batteries are economical and paying for themselves on the grid. If there are several of these occasions per year it could be a great fit.

It also seems likely that HVDC from sunnier areas like Spain or maybe even Morocco could be cheap enough. I'd recommend nuclear but EDF is having such great difficulty building it. HVDC and other exotic solutions like enhanced geothermal seem for more practical at the moment.

Do you ever actually converse with people or do you just DDoS them with random information. I made one simple point and you have not addressed it.

HVDC, long-duration batteries, and enhanced geothermal directly address your concern. And if they do not, you have not bothered to express your concern clearly.

		You’ve shifted to promoting renewables. That wasn’t the point. The point was cost-shift: rooftop customers still use the grid but avoid paying for fixed T&D. Address that.
