Question
Market clearing electricity prices are determined by the production cost of the last units demanded, essentially because:Electricity is a homogenous good, from the point of view of consumers.Producers produce electricity only from the last source in the merit order.The marginal cost of production of electricity are constantThat is how the European Commission designed the electricity markets.
Solution
The statement is referring to the economic principle of marginal cost pricing, which is used in various markets, including electricity. Here's a step-by-step explanation:
-
Homogenous Good: Electricity is considered a homogenous good because no matter where it comes from or how it is produced, it is the same from the consumer's perspective. This means consumers are indifferent about the source of electricity, they just want their demand to be met.
-
Merit Order: The 'merit order' is a way of ranking available sources of energy, especially electrical generation, based on ascending order of their short-run marginal costs of production. Producers will first use the cheapest resources. As demand increases, they will start using more expensive resources.
-
Marginal Cost of Production: The cost of producing one additional unit of electricity is the marginal cost. In the electricity market, this cost is not constant. It varies depending on the source of energy (coal, gas, wind, solar etc.) and the demand-supply situation.
-
Market Clearing Price: The market clearing price in electricity markets is determined by the cost of producing the last unit of electricity demanded. This is because as demand increases, more expensive sources of energy are used, raising the marginal cost of production. This higher cost is then reflected in the market price.
-
European Commission's Design: The European Commission has designed the electricity market in such a way that it operates on these principles. This is done to ensure efficient use of resources and fair pricing.

Consider an electricity market where the base of the demand curve is vertical and varieslinearly between 4000MW and 8000MW (so is equally likely to be found anywhere inthat range). Above 7500MW demand can be curtailed at a price of $4000/MWh.

A coal-fired power station produces electricity worth $40 per unit to consumers. However, for each unit produced air pollution is produced, costing $20, which is not reflected in the price of electricity paid by consumers. Suppose a Pigovian tax has been implemented to correct the market distortion. In the Social CBA the production of additional electricity should be priced at:
