What if, instead of paying for curtailed renewable power, NESO would use that budget to find the switch to individual heat pumps or heat pump fed district heating, possibly linked to (seasonal) solar or wind based heat storage? That could help absorb excess RES production locally while creating space on electricity grids.

Curtailment of renewable output will quickly rise to monstrous levels unless new markets can be developed for intermittent REe. A good candidate is massive thermal storage, heat reservoirs such as insulated waterproof pits, linked to district heating. Does not even have to be ultra-long duration interseasonal storage, as there is lots of wind output in the heating season. A short term answer that can sustain a fast roll-out is to use REe as available to displace gas heating, but Smart electricity tariffs need sorting. e.g. Low and negative prices at times.
