This paper presents a theoretical and empirical analysis of liquidity in the German intraday market for electricity. Two models that aim at explaining intraday liquidity are developed. The first model considers the fundamental merit-order and intraday adjustment needs as the drivers of liquidity...

This paper presents an analytical benchmark model for national intraday adjustment needs under consideration of fundamental drivers, market concentration and portfolio internal netting. The benchmark model is used to calculate the intraday market outcomes if (i) large and small players as well...

This article investigates the impact of the fuel mix structure in power generation portfolios on expected stock returns for major European power companies. The 22 biggest publicly listed European power producers are examined between January 2005 and December 2010. Based on the capital asset...

After a period of hibernation, the development of pumpedâ€hydro storage plants in Germany regains momentum. Motivated by an ever increasing share of intermittent renewable generation, a variety of energy players considers new projects, which could increase the available capacity by up to 60%...

Optimal capacity allocation for investments in electricity generation assets can be deterministically derived by comparing technology specific long-term and short-term marginal costs. In an uncertain market environment, Mean-Variance Portfolio (MVP) theory provides a consistent framework to...

Power systems with high shares of wind and solar power have to balance their intermittent nature. Pumpedâ€hydro storage plants can provide the required flexibility, while thermal backup plants offer an alternative. This paper proposes a model based on peakâ€loadâ€pricing theory to...

This paper links Hotelling's theory, in recent literature applied to an emission constrained environment, with the classical capacity planning framework to describe portfolio timeâ€paths in electricity production. Emission targets are considered by a ceiling on the stock of pollution. We...

This paper explores the economic implications of different contract durations in markets for on-line (primary and secondary) reserve capacity in Germany with the crucial feature of separate markets for spot energy and reserve capacity provision. The analysis is based on an equilibrium model...

Increasing renewable generation results in growing supply uncertainty. By now hydrostorages are the most efficient way of smoothing uncertain power supply. In liberalized and competitive markets the valuation of hydro storages investment projects needs to take the market information and...

Ueber das Fuer und Wider einer Foerderung Erneuerbarer Energien mittels spezifischer Foerderinstrumente wie dem EEG sowie ueber die bestmoegliche Ausgestaltung dieser Instrumente sind in den letzten Jahren viele sowohl praxisorientierte als auch wissenschaftliche Debatten gefuehrt worden. Dabei...
