@happyborg @katemorley The quickest way to break the stupid marginal price system would be to allow people to sell their generated surplus to others, within, say, a 30km radius, and ignore the marginal price targets. And that power is delivered first, backing out the gas gen.
Yes, that would need an aggregation system for billing, but itโs not impossible.
If I sell for, say, 10p/kWh, with a 1p transmission cost, my village could all pay 11p/kWh and not 25-35p.
