Die Kosten von Technologien zur Nutzung fluktuierender erneuerbarer Energien (EE) wie Windturbinen und Photovoltaik-Anlagen sind in den vergangenen 15 Jahren enorm gefallen. Waren solche Technologien anfangs nur durch substanzielle Subventionen für Firmen wirtschaftlich anzuwenden, sind sie...

We conduct a hybrid scenario exercise to analyze decarbonization pathways of the European power market and related distributional effects across countries as well as between consumers and producers. Our CIB analysis reveals qualitative scenarios that differ in the level of political (stringency...

We apply Open Street Map to identify available placement cells and Global Wind Atlas to determine average wind speeds on a 500 x 500m grid in Germany (1.3 million cells). Minimum distances to obstacles such a roads and buildings leave 535,000 potential placement cells. We calculate...

Bottom-up optimization models neglect the inclusion of investment behavior We introduce three investor types that differ in their investment cost specifications, financing costs, and discounting. This leads to a substantially different pace and rate of adoption for specific generation...

Policymakers misjudge results of technology-rich optimization models because those models specify investment cost differently and thus are not equally sensitive towards changing financing cost and discount rates. We apply an intertemporally optimizing power market model to analyze three...

Erdgas- und Strompreise hängen in Deutschland und Europa zwar fundamental zusammen. Doch warum verteuern Erdgaspreise die Strompreise so stark, obwohl der Erdgasanteil im Strommix verhältnismäßig gering ist? Was bedeutet das für europäische und deutsche Strompreise? Können die drei...

Nuclear stretching operation in Germany until April 15, 2023 brings down German (European) power prices by 6.01 percent (1.51 percent) until April 15, 2023 and by 2.98 percent (0.65 percent) in 2023, saving 4.8 TWH (8.6 TWh) of natural gas and 3.3 Mt (4.5 Mt) of CO2 emissions in 2023. Nuclear...

European energy crisis has three elements: skyrocketing prices for energy carriers such as natural gas, coal, as well as electricity, reduced nuclear power plant availability in France, and lower hydro power generation in Europe. This paper decomposes the effects of those elements on power...

When the supply of intermittent renewable energies like wind and solar is high, the electricity price is low. Conversely, prices are high when their supply is low. This reduces the profit potential in renewable energies and, therefore, incentives to invest in renewable capacities. Nevertheless,...

Detailed numerical models of power markets with millions of variables and equations are often perceived as black boxes, because differences in results cannot be traced back to single equations or assumptions, respectively. We unravel parts of those black box by determining the impact of...
