Record amount of solar energy in Eastern Germany

31.03.2020

We are accustomed to hearing from 50Hertz, the transmission system operator (TSO) from the north-east of Germany, remarkable record figures as regards the feed-in of wind-generated electricity into the TSO’s transmission grid. Nonetheless, the TSCNET shareholder has always ensured the security and stability of power supply, also under circumstances that temporarily put a strain on the system. The above-average wind energy feed-in of February 2019, for example, meant that wind and sun accounted for around 85% of electricity consumption.

Now there are also impressive figures from the photovoltaic sector: Never before has the 50Hertz system management fed in so much solar power as last week, when an often almost cloudless sky provided a lot of sunshine for photovoltaic installations. An all-time high was achieved on Monday, 23 March, when at midday the TSO integrated almost 8,500MW of photovoltaic power into the grid without having to throttle a single MW.

According to 50Hertz CEO Stefan Kapferer, these figures prove the TSO’s experience in managing weather-related fluctuations in electricity supply from renewable sources and in the secure integration of even the highest shares of renewable energies. And also in current times of crisis, the 50Hertz system management is well prepared: “The present electricity demand, which is lower now due to the measures to fight the corona pandemic, is also manageable.“ 50Hertz is monitoring developments very closely and will increase control power reserves if necessary, so that sufficient reserve capacities are available anytime. “These capacities complement the electricity feed-in from renewable energy sources and therefore guarantee the stable operation of the grid and the system,” explains Stefan Kapferer.

In the fourth week of March, a record amount of solar energy was fed into the 50Hertz grid without losses
