Power Generation from Renewable Energy in Germany – Assessment of 2015

Collated by Prof. Bruno Burger, Fraunhofer ISE; January 11, 2016, last updated on: January 13, 2016,

These slides visualize power generation data of 2015 along with trends in individual sources (renewable and conventional), including a comparison with the previous year.

In total, renewable energy sources – solar, wind, hydropower, and biomass – produced approximately 190 TWh of electricity in 2015, 30 TWh more than in the first half of 2014, equivalent to a 20% increase. Renewables thus made up around 35% of public net power supply.

Offshore wind generates more than 2,000 MW for the first time

Prof. Dr. Bruno Burger
July 10, 2015

On Wednesday, 8 July 2015, offshore wind turbines in German waters produced more than 2,000 megawatts (MW) of electricity for the first time. Turbines in the North Sea generated 1,840 MW of that amount for export to grid operator Tennet. The wind farms in the Baltic, which are connected to the 50 Hertz grid, produced 250 MW. In the first half of 2015, several new wind farms went into operation in the North Sea and the Baltic to make this new record possible.

The slides show time series of the production by photovoltaic, wind and conventional energies in Germany combined with the electricity prices (Day-Ahead and Intraday) of the European Energy Exchange, EEX. Furthermore analysis on the history of electricity prices are provided. The slides will be updated regularly to provide recent and transparent data and charts.

Solar Power Plants Deliver Peak Load

Statement Prof. Bruno Burger, Fraunhofer ISE
Freiburg, June 2011
(last update: January 2012)

The comfortable weather of the past weeks lured many outside. However, not only those looking for sun benefited from the beautiful weather, also solar power plants operated particularly well and delivered an important contribution to the power supply. Graphs based on data from the European Electricity Exchange (EEX) show that, depending on the weather, over midday up to 13.2 Gigawatts (GW) of solar power was delivered to the public grid. That corresponds to the net output power of up to ten nuclear power plants.

Solar power plants thus relieve the conventional power plants and significantly reduce the peak power demand. At the moment, in Germany, only four of the 17 Nuclear power plants are operating, therefore solar plants play an important role in a secure power supply. They absorb the peak loads during the day, thereby allowing the conventional power plants to operate with an almost constant power from 7am to 10pm.
The figures 1 and 2 show the planned and actual power production from solar, wind and conventional power plants on Sunday and Monday the 8th and 9th of May 2011. These figures show how well the predicted and actual production agrees.

Figure 3 shows the electricity production over one week. The following figure shows the production over one month. All figures show that solar power is a reliable producer and that it can deliver valuable peak load power. One can also see that every day during this week the complete midday peak load was covered by solar power. The conventional peak load power plants were significantly relieved.

According to Prof. Dr. Bruno Burger from the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg the figures show that the contribution of solar power is very predictable and steady, revealing no rapid changes, as can occur for example, with wind power. “The reason is the large spatial distribution of the solar plants, where local weather conditions, such as moving clouds, are averaged out completely”.
