French National Grid status

Demand: This is the total demand of the entire country (excluding exports) less any unmetered generating sources like wind and domestic solar installations. France's total demand reflects not only its domestic demand but also its place as a major supplier of base-load and renewable balancing power to Western Europe.

Nuclear: Frances primary electicity generating technology. Surplus is exported across Europe. Variations in output are either signs that reactors have been deliberately throttled to match lower demand, or that refuelling or maintenance is ongoing.

Hydroelectric power: France has a significant number of hydro-electric stations (mainly in the Alpine foothills) which are used to deliver a considerable amount of electricity, and also balance the grid against fluctuations in European renewable sources

Gas: France has litle reliance on gas but it's has a few gas power stations that run as base load in winter.

Coal: Coal is not a large contributor to the French grid. Coal plants are now restricted in running hours for emissions, so tend to run in winter when prices are higher.

Oil: These are stations running thick fuel oil or bunker oil or in some cases diesel.

Biomass: These power stations are either (parts of) old coal plants that have been converted to run on biomass, or purpose built biomass burners, or municipal waste burning stations.

Pumped Storage: France has a single pumped storage power station - The Grand'Maison Dam capable of absorbing 1.8GW and delivering 2.4GW. Unlike the UK France only records the energy beng stored, not delivered. That is included in hydro. In general it is replenished whenever there is surplus power on the grid.

Solar: This is the metered solar farms. Yes, don't ask me why there is 10MW at night, a fact that is airbrushed out of RTE's user friendly website...

Wind: This is the total contributed by metered wind farms. The variability of wind leads to very high fluctuations in output, more or less in step across the whole of Western Europe.

European frequency: Most of Western Europe is synchronised to a commmon frequency, with all member countries participating to keep the stability..

German Exports: Germany exports its surplus of renewable energy to France by day, or when the wind is high, but at night or when the wind is low it imports.

The impact of Germany's Energiewiende, especially solar, can be seen in terms of the wildly fluctuating value of the import/export balance.

Belgian exports: Belgium is largely nuclear, but has some coal and gas, and a little 'renewable' capability. It is usually a net importer of power from France.

Italian exports: Italy has a deficit of power and relies on French nuclear power to enable it to function alongside its predominantly gas powered grid, with some hydroelectricity and pumped storage. 10% of Italy's electricity is imported, mainly from France.

Swiss exports: Switzerland has good hydro and nuclear of its own, but not quite enough and relies on France to make up the balance.

Spanish exports: Spain has an increasing amount of renewable energy, and when it works it's a net exporter, at other times it imports to supplement its mainly gas powered grid, with a little nuclear and hydro.

UK exports: This is the 2GW connector to England. Generally the UK is a net importer, but at times of low renewable energy the UK coal and gas stations are able to top up the European Grid.
