This is the main issue. People simply cannot afford to use this extra power. If power was cheap then all kinds of devices would switch to electric, especially heating and cars.

The other issue is that the UK has unpredictable weather and no way to store energy at a grid-level. It can store enough to load balance spikes but there is still nothing to replace the months of gas we once had stored in giant salt chambers (you can thank Liz Truss for decommissioning those).

Without vast amounts of long-term energy storage we will continue to throw away power when we have too much and fire up gas generators when wind power isn't making any (which happens surprisingly often).
