Optimal capacity mix and scarcity pricing
For example, if the annualized fixed cost of the marginal power plant is EUR 50,000 per MW (or EUR 50 per kW) the electricity price rises to EUR 50,000 per MWh plus the variable cost of the plant. This is called "peak- load pricing" or "scarcity pricing", because overall capacity is scarce in this, and only this, hour.
