Renewables briefly covered 78 percent of German electricity

[font size=3]On July 25, Germany surpassed the old record of 74 percent renewable electricity. But perhaps the most interesting aspect is power trading between France and Germany on that day. Craig Morris explains.

At the end of July, the storm Zeljko passed over northern Europe, causing considerable wind damage and flooding in some areas. Here in southern Germany, however, it was a relatively sunny day. In the north, where it was windy, Germany has most of its wind turbines installed. In the south, it has most of its solar. The combination of sunny weather in the south with strong wind throughout the country is rare – and led to a new record.
The chart above visualizes the situation well, but we still need to include biomass (4.85 GW) and hydropower (2.4 GW). The total renewable electricity on Saturday afternoon was therefore 47.9 GW. We then also need to exclude the 8.75 GW of net power exports below the baseline in the chart above to calculate total domestic power demand, which then comes in at 61.1 GW. In that calculation, Germany had roughly 78 percent renewable electricity as a share of domestic demand for a few hours.
