The harmonization and integration of separate national energy markets to an interconnected internal European market is a top priority of the European Commission. However, as energy policy largely remains subject to national sovereignty, a higher degree of integration can cause unilateral...

We measure the degree of market power execution and inefficiencies in Alberta's restructured electricity market. Using hourly wholesale market data from 2008 to 2014, we find that firms exercise substantial market power in the highest demand hours with limited excess production capacity. The...

A capacity mechanism next to the energy-only market provides necessary investment incentives that spot markets lack. The adequate capacity mix can only be achieved by accounting for the current transition phase to electricity generation with a growing share of renewables. We show that an...

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...

This paper studies the interaction between hydro and wind power in hydro-thermal-wind power system. Socially efficient and monopoly hydropower allocation solutions are presented. Market power utilization potential for hydropower is reduced during low demand periods when residual demand crosses...

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...

We report results from a large field experiment that with a few hours prior notice provided Danish residential consumers with dynamic price and environmental signals aimed at causing them to shift their consumption either into or away from certain hours of the day. The same marginal price signal...

Decarbonization goals of the European Commission foresee different future scenarios for the European power market of which all are exceeding 60% renewables in the power system.3 High shares of intermittent renewable sources require significant changes to the physical system and impact the...

Long-term energy contracts have featured prominently in many decisions of the European Commission to support the opening of the electricity markets. Contracts were seen to foreclose the market hence the Commission comprehensively unwound pre-existing long-term contracts and formulated strict...

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...
