The impact of weather and of batteries on the investment risk for backup gas power plants in a largely renewable energy system

With an increasing wind and photovoltaic share, the German generation mix becomes more weather-dependent. Backup technologies can help to bridge scarcity moments. These rare moments with high prices are the main events for their cost recovery. However, the uncertain revenue flow combined with long payback periods leads to high investment...

The Impact of Extreme Weather Conditions on a Renewable Dominated Power System in Germany and Measures to Maintain Security of Supply

With an increasing share of photovoltaic and wind in the German generation mix, the power supply reduces its CO2 emission and becomes more weather dependent. In order to guarantee the security of supply, the volatile power output by the renewables asks for compensation by other sources. These backup technologies have to cope with a variety of...
