Frequency stability requires equalizing supply and demand for electricity at short time scales. Such electricity balancing is often understood as a sequential process in which random shocks, such as weather events, cause imbalances that system operators close by activating balancing reserves. By...

El propósito de este artículo es hacer un análisis de la seguridad en el suministro de electricidad en Colombia, considerando el nuevo esquema del Cargo por Confiabilidad, modelo adoptado en Colombia para garantizar las inversiones en generación. Para esto se analiza la diferencia entre...

Congestion management schemes have taken a prominent place in current electricity market design discussions. In this paper, the implications of establishing zonal pricing in Europe are analyzed with regard to potential zonal delimitations and associated effects on total system costs. Thereby, a...

Natural gas is playing an important role in Germany, Europe, and around the globe as a bridge fuel in the transition toward lower-carbon energy systems. In this context, natural gas price development is very important, particularly in relation to its competitor, coal. Up until a few years ago,...

Die "Energiestrategie 2030" setzt den Weg Brandenburgs in Richtung erneuerbarer Energien konsequent fort. Die am 28. Februar vom Kabinett der Landesregierung verabschiedete Strategie sieht den schrittweisen Ausstieg aus den fossilen Technologien hin zu einer vollständigen Stromerzeugung aus...

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...

Requirements for the electricity network in Germany increased in recent years due to the energy transition. The utilization of existing infrastructure applying so called congestion management becomes more important. Regional pricing might help to set the right incentives for generation...

In den kommenden zwei Jahrzehnten wird die CO2-Abscheidung auf dem deutschen Stromsektor keine Rolle spielen. Dies zeichnet sich spätestens seit der öffentlichen Bekanntgabe von Bundesumweltminister Norbert Röttgen vom 29. Oktober 2011 und der Absage des CCTS-Demonstrationsprojekts am...

This paper exploits unique features of a recently introduced tariff schedule for natural gas in Buenos Aires to estimate the short-run impact of price shocks on residential energy utilization. The schedule induces a non-linear and nonmonotonic relationship between households’ accumulated...

The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...
