The German government aims at a climate-neutral building stock by 2050 to reach the goals defined in the Climate Action Plan 2050. Increasing the energy efficiency of existing buildings is therefore a high priority. For this purpose, investments of private homeowners will play a major role since...

Nonlinear autoregressive Markov regime-switching models are intuitive and frequently proposed time series approaches for the modelling of electricity spot prices. In this paper such models are compared to an ordinary linear autoregressive model with regard to their forecast performance. The...

The liberalization of electricity markets has triggered research in econometric modelling and forecasting of electricity spot prices. Moreover, both the demand and the supply of electricity are subject to weather conditions. Therefore, we examine the relation between hourly electricity spot...

Employing a quantile regression model, we investigate the impact of renewable sources on their unit revenues (absolute cannibalization) and value factors (relative cannibalization), as well as the cross-effect between technologies. The results indicate that an increase in wind and solar share...

This paper analyzes the valuation of day-ahead Physical Transmission Rights (PTRs) on the German-Dutch interconnector. From a financial perspective, PTRs are options written on the difference between the German and Dutch hourly electricity prices. We propose a model for the valuation of...

Improving the energy efficiency of residential buildings is of paramount importance to reduce CO2 emissions and hence to achieve a climate-neutral building stock – the objective of the German government for 2045. Thereby, a focus on the existing building stock is needed, as regulations for new...

Industrial demand response can play an important part in balancing the intermittent production from a growing share of renewable energies in electricity markets. This paper analyses the role of aggregators – intermediaries between participants and the electricity market – in facilitating...

We describe the determinants of energy intensity, carbon intensity, and CO2 emissions in the German manufacturing sector between 1995 and 2007, applying the LMDI index decomposition technique not to aggregate but to micro data. We trace back changes in total CO2 emissions from manufacturing to...
