éCO₂mix - Market data

Power exchange data

Spot prices are the prices at which electricity is traded the day ahead, for delivery the following day. The prices shown here for France are those of the EPEX Spot market, but other power exchanges operate in the French electricity market.

As long as the exchange capacity between two countries is not reached, the price is the same in both countries. However, insufficient exchange capacity gives rise to a price difference between the two countries. 

It should be noted that prices for Great Britain, published in sterling, are converted using the rates published by the Banque de France.

Europe’s interconnected electricity system

The interconnected European power transmission system carries flows of electricity throughout Europe. Harnessing the complementary nature of national energy mixes by pooling generating capacity, electricity exchanges benefit the community of Europe in three ways: strengthening security of supply and the operational security of interconnected systems; reducing continent-wide production costs by using the cheapest (and least carbon-intensive) means of production at all times; and facilitating the integration of renewable energies.

This pooling takes advantage of the differences in consumption patterns across European countries. Peak consumption, for example, does not occur at the same time of day or during the same season in all countries (peaks occur in the afternoon in Spain, in the evening in France, and in the morning in Scandinavian countries). Furthermore, pooling also makes the most, to a certain extent, of the differences in the production profiles of intermittent renewable energy sources.
