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...

Small decentralized power generation units (DG) are politically promoted because of their potential to reduce GHG-emissions and the existing dependency on fossil fuels. A long term goal of this promotion should be the creation of a level playing field for DG and conventional power generation....

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...

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...

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...

After a period of hibernation, the development of pumped-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%...

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...

In this article we discuss welfare-optimal capacity allocation of different electricity generation technologies available for serving system demand. While the classical peak load pricing theory derives the efficient portfolio structure from a deterministic marginal production cost curve ("merit...

This paper investigates the incentives market participants have in the German electricity balancing mechanism. Strategic over- and undersupply positions are the result of existing stochastic arbitrage opportunities between the spot market and the balancing mechanism. This strategic behavior can...

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