Increasing penetration of residential photovoltaic (PV) systems has intensified concerns over the related impacts on utility revenue and the equity of deployment subsidies. Community solar (CS) has surfaced as an alternative deployment model for PV that could potentially mitigate these concerns,...

How should we select winning bids of generation units for strategic reserves that consist of capacity bids and energy bids? In this paper, we analyze two selecting mechanisms (scoring rules): "simultaneous" and "sequential". In case of a simultaneous scoring rule, capacity and energy bids are...

This article analyses cross-border effects of capacity mechanisms and discusses whether such mechanisms countervail the goals of European Market Integration. Using a two-country-model, the countries' policy options are analysed from a game-theoretical viewpoint. A model simulation identifies the...

Liberalized electricity markets are characterized by fluctuating priceinelastic demand of non-storable electricity, often defined by a substantial market share held by one or few incumbent firms. These characteristics have led to a controversial discussion concerning the need for and the design...

The power exchange and the real-time markets used by the system operator differ in how system constraints are managed. This can result in regulatory arbitrage, which can increase consumer costs, increase the risk of power outages and distort investment incentives. This paper uses a...

Renewable energy installations are rapidly gaining market share due to falling technology costs and supportive policies. Meanwhile, the energy price crisis resulting from the Russian-Ukrainian war has shifted the energy policy debate toward the question of how consumers can benefit more from the...

The unbundling of formerly vertically integrated utilities in liberalized electricity markets led to a coordination problem between investments in the regulated electricity grid and investments into new power generation. At the same time investments into new generation capacities based on...

Analyzing commodity market dynamics, we observe that price volatility increases with reduced contract duration. In this paper, we derive a theoretical model depicting the price formation in two markets with altering product granularity. Supplemented by empirical evidence from German electricity...

Balancing power markets ensure the short-term balance of supply and demand in electricity markets and their importance may increase with a higher share of fluctuating renewable electricity production. While it is clear that shorter tender frequencies, e.g. daily or hourly, are able to increase...

Durch die steigenden Anteile erneuerbarer Energien an der Stromproduktion wird die kostengünstige Systemintegration der Anlagen immer wichtiger. Als systemfreundlich werden dabei Technologien und Standorte bezeichnet, die günstiger und einfacher zu integrieren sind, weil sie, im Gegensatz zu...
