German transmission system operator (TSO) 50Hertz successfully integrated a record 8500MW of solar electricity into the grid in a single morning on 23 March.
The company said that lots of sun and an almost cloud-free sky were the reasons for the record volume.
50Hertz also said February was a strong month for energy production.
Renewables were able to cover most of the electricity demand between the Baltic Sea coast and the Ore Mountains, with wind and sun accounting for 85% of electricity consumption.
“In the first months of this year, the wind blew frequently and strongly, especially in the northern regions of the 50Hertz grid area, resulting in above-average wind energy feed-in,” 50Hertz said.
50Hertz chief executive Stefan Kapferer said: “Our colleagues are able to deal routinely with meteorological fluctuations in the supply of electricity from renewable energies and are even able to integrate the highest feed-in values into our system.”
Kapferer added: “The current decline in electricity demand as a result of the corona pandemic measures is also well manageable for us at the moment.”
The chief executive said adapting to short-term changes in supply and demand is one of the typical requirements for system management.
“We are monitoring the situation very closely and, if necessary, we will increase our reserve reserves,” said Kapferer.
