In the current study the savings of CO2 emissions due to the use of ground source heat pump (GSHP) systems was investigated in comparison to conventional heating systems. Based on a subsidy program for GSHP systems in southwest Germany, the regional, average, and total CO2 savings of 1105...

Die Netzausfälle im Münsterland, der Erdgasstreit zwischen Russland und der Ukraine und auch die in Deutschland wieder begonnene Diskussion um die Nutzung der Kernkraft setzten die Frage nach einer zuverlässigen Energieversorgung auf die Tagesordnung. Für Christa Thoben,...

This paper contributes a theoretical analysis of the effects of regulation on the timing of monopoly investment under certainty in a setting with lumpy investment outlays. We distinguish between price-based regulation and cost-based regulation. To motivate investment, we focus on wear and tear...

Energy and climate policy drive large scale integration of distributed generation and demand side management, with massive consequences for distribution grids. New technologies and actors shape the transformation of electricity networks towards smart systems. We argue that future regulation of...

In an intertemporal model, we analyze the timing of irreversible and lumpy monopoly investment under certainty. There are two reasons for investing, i.e. wear and tear leading to replacement investment and demand growth leading to expansion investment. Both in a single investment setting and in...

Smart contracts based on voluntary participation and optionality can be a low transaction cost solution to implement locational signals in distribution networks and thereby avoid network investment. This paper examines the efficiency properties of smart contracts. Based on a three-node example...

The increasing share of distributed generation causes massive network investment. Energy and network pricing can help to reduce the investment need. This paper examines and discusses different models for locational pricing in the distribution network. Locational energy pricing is largely...

For the large-scale integration of electricity from renewable energy sources (RES-E), the German system seems to reach its limits. In 2009, the electricity wholesale market experienced serious negative prices at times of high wind and low demand. The feed-in system in Germany consists of a fixed...
