A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how...

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...

Due to increasing shares of renewable energies in electricity production, the cost-effective system integration of these installations is becoming more and more important. Technologies and locations are viewed as system-friendly when they are more cost-efficient and easier to integrate because...

Restricted participation in sequential markets may cause high price volatility and welfare losses. In this paper we therefore analyze the drivers of restricted participation in the German intraday auctin which is a short-term electricity market with quarter-hourly products. Applying a...

With a growing number of distributed energy resources, the electricity network is challenged with a higher quantity of technical problems such as capacity congestions and over- or under-voltages. One often-discussed approach to solve these problems, especially in the European zonal electricity...

We analyze the gross welfare gains from real-time retail pricing in electricity markets where carbon taxation induces investment in variable renewable technologies. Applying a stylized numerical electricity market model, we find a U-shaped association between carbon taxation and gross welfare...

Deutschland hat im internationalen Vergleich bereits seit langem sehr hohe Strompreise. Da Strom teilweise aus Gas erzeugt wird, haben sich die Preise infolge des Ukrainekriegs weiter erhöht. Aber auch die gestiegenen CO2-Preise zur Reduzierung des CO2-Ausstoßes wirken weiter preistreibend....

Increasing shares of intermittent renewable energies challenge the dominant way to trade electricity ex-ante in forward, day-ahead, and intraday markets: Coal power plants and consumers cannot react to the stochastic element of renewables, whereas gas turbines can. We use a theoretical model to...

In current power markets, the bulk of electricity is sold wholesale and transported to consumers via long-distance transmission lines. Recently, decentralized local power markets have evolved, often as isolated networks based on solar generation. We analyze strategic pricing, investment, and...

Short-term electricity markets are key to an efficient production by generation units. We develop a two-period model to assess different bidding formats to determine for each bidding format the optimal bidding strategy of competitive generators facing price-uncertainty. We compare the results...
