In den letzten Jahren wird vermehrt die Sorge geäußert, dass die Energiewende die Sicherheit der Stromversorgung in Deutschland langfristig durch Engpässe und Stromausfälle gefährden könnte. Während der Ausbau von volatiler Stromerzeugung aus Wind- und Sonnenenergie mit hohem Tempo...

Die Lage der russischen Wirtschaft ist dramatisch. Um 3,7% ist die gesamtwirtschaftliche Leistung 2015 eingebrochen. Die verhängten Wirtschaftssanktionen sowie der Ölpreisverfall haben zu der Abwärtsspirale beigetragen. Doch die eigentlichen Schwächen der russischen Wirtschaft sind eher...

Photovoltaic systems generate electricity around noon, when many homes are empty. Conversely, residential electricity demand peaks in the evening, when production from solar sources is impossible. Based on a randomized control trial, we assess the effectiveness of alternative demand response...

System security in electricity markets relies crucially on the interaction between demand and supply over time. However, research on electricity markets has been mainly focusing on the supply side arguing that demand is rather inelastic. Assuming perfectly inelastic demand might lead to delusive...

Gas-fired power plants constitute a direct and important link between the gas and the electricity sectors and thus between the Target Models for electricity and gas. As the need for a flexible operation of gas-fired power plants will increase in tomorrow's low-carbon power markets, so also will...

With increasing variability of demand and supply, transmission system operators (TSOs) across Europe adapt their internal processes and operational approaches. These processes comprise different interfaces with other market participants (e.g. via balancing markets, reserve procurement or NTC...

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 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...

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...

We discuss the implications of two price zones, i.e. one northern and southern bidding area, on the German electricity market. In the northern zone, continuous capacity additions with low variable costs cause large regional supply surpluses in the market dispatch while conventional capacity...
