Photovoltaics

Photovoltaics in Germany is a fast growing part of the renewable electricity generation. The installed capacity in the country has raised to an amount of around 42 gigawatts (As of end of 2017). About 10 gigawatts of solar power are already installed in the control area of 50Hertz. This also involves balancing the fluctuations in power feed-in during day and night.

Today, solar power represents about three per cent of the German energy mix, and the trend is rising. Other than for conventional power plants, the generation of electricity by photovoltaic installations is subject to fluctuations. As a result, solar power seldom corresponds to the actual demand. The operators of the German energy supply grids are nevertheless obliged by the Renewable Energy Act (EEG) to feed in all electricity generated from renewable sources into the grid. In order to maintain the balance between offer and demand, operators have to compensate for fluctuations due to the weather. 50Hertz ensures this balance.

Below, you will find a number of important key figures relating to Photovoltaics in the 50Hertz control area.

Data based on the extrapolation of the actual figures (15 minute mean capacity figures). The figures are transmitted to 50HzT every 15 minutes by two providers (Meteocontrol & EnergyMeteoSystems). The individual extrapolations are used to generate a meta extrapolation. The values refer to solar power, including direct marketing.

The forecast figures and extrapolated actuals of Photovoltaics feed-in for the 50Hertz control area are available on the following sites:

The relevant audit certificates in connection with the feed-in time series will be authoritative for final EEG settlement.
