In France nuclear + water + wind + solar, all low marginal cost, cover the consumption at 99%+ timestep in the day-ahead market, but there is like 18GW of interconnect, so gas + fuel + coal are running to power our neighbours, in the electricity market the last called capacity in the cost curve set the same price for the whole time step (with some provision for interconnect capacities). Without interconnect French day ahead power price would be at like 17€/MWh, but thanks to our neighbours it is at 150. But still the day ahead market doesn't set the price paid by the consumer, there is long term futures, and 100TWh/year of nuclear offered at 42€.
