Power Generation from Renewable Energy in Germany – Assessment of 2016
Collated by Prof. Bruno Burger, Fraunhofer ISE; January 2, 2017, updated: January 6, 2017
These slides visualize power generation data of 2016 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 186 TWh of electricity in 2016. There was no increase in production compared to 2015. Renewables thus made up around 34% of public net power supply. The share in gross power supply – including power plants in the processing sector, the mining sector, quarries, and excavation – is around 32%.

Fraunhofer ISE publishes "Photovoltaics Report"
Last updated: November 17, 2016
Photovoltaics is a fast growing market: On average, installations have grown by 44% annually in the period from 2000 to 2014.
The intention of this presentation is to provide up-to-date information. However, facts and figures change rapidly and the given information may soon be outdated again.
Approach for the integration of renewable energy in Europe and North Africa
Prof. Dr. Werner Platzer, Fraunhofer ISE
March, 12, 2016
The percentage of renewables in the electricity supply is steadily growing worldwide. Using a combination of different renewable sources, an ecological and economical electricity mix can be realized across national borders. Decisive here is the reliable supply, storage and distribution of renewable electricity. In the Supergrid project, several Fraunhofer institutes joined together to research just how such an electricity and transmission grid between North Africa and Europe could function. They developed scenarios for a renewable energy system in the MENA region and compared potential technologies. Detailed solutions were proposed and regulatory mechanisms were evaluated.
Study: What will the Energy Transformation Cost?
Pathways for Transforming the German Energy System by 2050
Prof. Dr. Hans-Martin Henning / Dr.-Ing. Dipl.-Wirt.-Ing.Andreas Palzer, Fraunhofer ISE
Full Study: February 2016 / Short Summary: December 15, 2015
The transformation of the energy system in Germany is a declared political goal of the federal government. By 2050, greenhouse gas emissions are to be reduced by at least 80 percent under 1990 levels. This necessitates a massive reduction in energy-related CO2 emissions, forcing a fundamental restructuring of the present energy system towards a largely carbon-free energy supply. The transformation requires major investments and will not happen of its own accord. Scientists at the Fraunhofer Institute for Solar Energy Systems ISE now presented a study which investigates the system and cost developments of the German energy system transformation in line with meeting the declared climate targets. The study covers the period starting from today up to 2050. The model-based study considers all relevant energy sectors and energy carriers to provide a detailed analysis on how Germany can achieve its climate goals through efficient energy use and renewable energy. Considering various scenarios, simulations show different, cost-optimized pathways for achieving the energy transformation.
Study: Current Status of Concentrator Photovoltaic (CPV) Technology
Dr. Simon P. Philipps, Dr. Andreas W. Bett, Fraunhofer ISE / Kelsey Horowitz, Dr. Sarah Kurtz, National Renewable Energy Laboratory NREL, USA
Version 1.2, February 2016
The German Fraunhofer Institute for Solar Energy Systems ISE and the US National Renewable Energy Laboratory, NREL, have compiled a study that describes the status of both the current market as well as the state-of-the-art for concentrator photovoltaic (CPV) technology. This young technology has achieved tremendous progress and has the potential for delivering solar electricity at a cost-competitive level in sun-rich regions with high direct irradiation values. The study gives an overview of all installations bigger than
1 MW, also of all companies active in the field of high and low concentration technologies as well as of efficiency values and the levelized cost of electricity. The study will be updated every half year.
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.

According to a study by the Fraunhofer Institute for Solar Energy Systems ISE commissioned by Agora Energiewende, solar energy will become the cheapest power source in many parts of the world. By 2025, solar power in sunny regions will be cheaper than power from coal or gas.
Electricity Spot-Prices and Production Data

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.
Study: Levelized Cost of Electricity - Renewable Energy Technologies
Dr Christoph Kost, Noha Saad Hussein, M.Sc., Fraunhofer ISE
The study compares the present costs for conversion of different energy forms into electricity and gives a prognosis for the further cost development up to 2030. The scientists in Freiburg analyze both the levelized cost of electricity (LCOE) from renewables as well as from conventional energy technologies. They present comparative figures for new power plants constructed in Germany, which are based on solar, wind energy and biogas as well as brown coal, hard coal and gas.
As commissioned by the German embassy in Cairo, the Fraunhofer Institute for Solar Energy Systems ISE, in cooperation with SolarizEgypt, has also calculated the electricity generation costs (LCOE) for renewable technologies and conventional power plants in Egypt. The full study (December 2016) is available in english and arabic language.

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”.
