Das Zeitdreieck Versorgungssicherheit, Wirtschaftlichkeit und Umweltschutz beschreibt grundlegende Ziele der Energiepolitik. Für die Wirtschaftlichkeit ist funktionierender Wettbewerb wesentlich, im Bereich der Netze ist jedoch staatliche Regulierung erforderlich. Im Hinblick auf Umweltschutz...

The profitable exploitation of asset portfolios in the European electricity markets has become more challenging in recent years. This is particularly true for combined heat and power (CHP) generation units that are often facing must-run conditions due to heat demands that need to be satisfied....

Increasing infeed from renewable energy sources poses considerable challenges to system operators who are in charge of power system reliability. Accordingly, the frequency of network congestion and the corresponding congestion management costs have increased dramatically over the last years and...

Hydro electricity generation is of great importance for the current and the future electricity system since it provides electricity without emitting CO2 and moreover hydro reservoirs offer high operational flexibility. With increasing shares of fluctuating renewable energies, their value is even...

Climate change mitigation requires governmental intervention, but different choices are at hand. While economists in general advocate for first-best instruments, reality looks quite different, with especially many subsidy schemes for renewable energies being used. Supporters of these schemes...

The German housing stock needs substantial energetic retrofit to meet carbon reduction targets. Various instruments are available to motivate building owners to improve the energy efficiency of their dwellings. These instruments mainly focus on the economic issue of funding and financing energy...

There is a broad consensus that the energy transition planned in Europe, along with an increasing share of renewable energy sources, demands a sufficient number of flexibility providers. The established flexibility procurement mechanisms, notably the reserve markets, are expected to reflect the...

German Abstract: Die gekoppelte Erzeugung von Strom und Wärme in KWK-Anlagen ist eine der brennstoffeffizientesten Erzeugungsformen im Strommarkt. Aus diesem Grund wird sie in vielen europäischen Ländern gefördert und ihr Ausbau ist erklärtes Ziel von Regierungen und...

Increasing shares of fluctuating renewable energy, the integration of European electricity grids and markets as well as new technologies induce continuous change in the European energy system. Due to these changes, fundamental electricity system and market models that have been developed and...

The ongoing transformation process towards a low or even zero emission energy system is facing a steadily increasing complexity, notably through variable renewable energies and sector coupling. At the same time, the necessity for long-term decisions associated with high capital costs...
