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...

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...

With increasing amounts of power generation from intermittent sources like wind, transmission planning has not only to account for the expected load curve but also for the stochasticity of volatile power infeeds. Moreover investments in power generation are no longer centrally planned in...

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...

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....

Power systems with high shares of wind and solar power have to balance their intermittent nature. Pumped-hydro storage plants can provide the required flexibility, while thermal backup plants offer an alternative. This paper proposes a capacity planning model to describe the efficient technology...

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...
