During the last quarter of 2016 and beginning of 2017, French electricity market has been coping with the unavailability of several nuclear power plants. Gas power plants in France, and as well as in neighboring countries thanks to electricity interconnections, have largely made up for the resulting additional power needed. This illustrates how close electricity and gas system are interlinked, providing flexi- bility and solidarity, and optimising production capacities in each country through interconnections. The facts previously described highlight the importance of guaranteeing security of gas supplies and show potential collateral effects of tense gas supply situations on electricity system. As it can be seen in figure 5.11, high electricity prices were reached in the South Region, especially for France, in the last months of 2016 and January 2017.
