The UK system has a "capacity auction", separate from the spot price, which covers dispatchable generation.
"Through the auction, government has procured 49.26GW of capacity at a clearing price of £19.40kW" (second link). Note units are kW not MWh.

Certainly some markets have prices that vary through the day to give generators the incentive to generate when power is needed most if they have that flexibility.
