Market power in electricity wholesale markets arises when generators have incentives to mark up their offers above the cost of production.I model a transmission network with a single line. I derive optimality conditions for supply functions for generators who supply energy at both ends of the...

This paper looks at the restructuring of European electricity markets that has been taking place since the 1990s. This liberalisation process, driven largely by EU legislation aiming to create a single market for electricity, has led to significant changes in how electricity markets in member...

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...

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...

This article explores key market design issues to be addressed in future electricity markets dominated by intermittent renewable generation with near zero private marginal costs for generating electricity. Changing technology mixes will change market outcomes, but they do not change the...

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...

In this paper,the trade-off between inefficient transmission forward markets (in nodal pricing regimes) and the inefficiency induced by hiding transmission constraints from the market (in zonal pricing regimes) is analyzed. First, a simple two node model formalizing the general trade-off is...

The expansion of heat pumps drives the electrification of the heating sector which is important to achieve Germany's ambitious climate targets. This paper examines the impact of heat pumps in combination with thermal storage on the flexibility of the German electricity system in 2030, focusing...
