Euronews' headline is pure clickbait.

The UK proposed only to supply free or discounted excess wind power to nearby homes, on windy days (not all the time, and not predictable). And that only because "Sometimes there is too much wind for our outdated grid to handle, especially in Scotland and the East of England."

“Rather than paying wind farms to switch off we’re trialling a new system where people who live near these constrained areas get cheaper - or even free - electricity.”

So, not applicable to the other 90+% of homes, or for the other 90+% of the year.

Surprise surprise. Australia is exploring 3 free hours of supply where people have modern Time Of Use (TOU) digital meters. And yes, owners of EV and battery stacks are discussing how to maximise import and arbitrage storage for best pricing/cost decisions in this model.
