Negative electricity prices arise when supply exceeds demand. With the increasing expansion of renewable energies, this issue is becoming particularly relevant for operators of photovoltaic systems when the systems are taken off the grid during periods of negative electricity prices. In Germany, there is no longer a feed-in tariff during these periods. In addition, the billing period is changed from hourly to quarter-hourly.<\/strong><\/b><\/p>

Negative electricity prices mean that electricity suppliers have to pay to have their electricity taken off the grid. This happens when demand is low but supply is high and the grid cannot absorb any more electricity. This phenomenon occurs, for example, when strong winds and sunshine produce an abundance of electricity, but there is insufficient storage capacity or export options available. In such cases, large photovoltaic systems, for example, are curtailed or taken off the grid altogether, because otherwise they would have to pay for the purchase of their electricity and would push the electricity price even further into negative territory with their supply.<\/p>

Negative electricity prices mostly occur at midday and from April to September<\/strong><\/p>

Negative electricity prices follow certain patterns. During the course of the day, they frequently occur in the German grid between 10:00 and 17:00, with a peak between 12:00 and 15:00. (Figure 1)<\/p>

Over the course of the year, most hours with negative electricity prices occur between April and September. Both the distribution by hour during the day and the distribution by month show a clear meteorological correlation: solar radiation is most intense at midday, and April to September are the sunniest months of the year. (Figure 2).<\/p>

\"Stunden<\/a><\/p>

Looking at the distribution of negative electricity prices across the days of the week, Saturdays and Sundays are particularly affected because less work is done on these days and large consumers do not need energy. Grids are then more quickly overloaded and photovoltaic systems are shut down more often. (Figure 3).<\/p>

Legislative amendment ends feed-in tariffs in times of negative electricity prices<\/b><\/p>

In order to meet the challenges of negative electricity prices, the German Bundestag passed a new law on 31 January, which was approved by the Bundesrat on 14 February. Among other things, the Renewable Energy Sources Act (EEG) adjusts the regulations on remuneration for renewable energy systems in times of negative electricity prices:<\/p>
