France started supplying natural gas to Germany during the energy crisis.
Since Thursday, gas has been flowing through the only connection point between the two countries near Niedergailbach in Saarland, the network operator GRTGaz announced in Paris.
"In a new energy situation related to the war in Ukraine, France is in solidarity with its German neighbor by supplying gas directly to it." Initially, 31 gigawatt hours flow across the border every day, the maximum capacity is 100 according to GRTGaz gigawatt hours per day.
Since the only line between the two countries was originally only intended for the delivery of gas from Germany to France and not the other way around, adjustments had to be made first.
The network operator explained that these were made in view of the sharp decline in Russian gas supplies to Europe and as part of European solidarity for energy security.
In return, France, whose nuclear power plants are weak at the moment, is to receive electricity from Germany in order to get through the critical winter months.
Due to maintenance, only 30 of the 56 nuclear power plants are currently in operation, as President Emmanuel Macron said on Wednesday evening.
In the next few weeks, 40 power plants are expected to be back online and, according to Macron, 46 in January.
However, recent strikes by power plant workers could thwart these plans.
