Energy markets are systems for effecting the purchase and sale of electricity using supply and demand to set the price. A typical energy market involves a wholesale market for electricity generation, when competing generators offer their electricity output to retailers, and a retail market for electricity retailing, when end-use customers choose their supplier from competing electricity retaile...

This paper quantifies the degree of market power in the German wholesale electricity market. A fundamental model is used to derive competitive marginal cost estimators which are compared with observed electricity prices. Marginal costs are calculated focusing on market fundamentals such as plant capacities, fuel prices, and load structures. In addition, international power exchange and dynamic ...

In this paper a model based analysis of competition in the German electricity market is presented. Applying a multi-regional two-stage model, which captures interregional transmission constraints and the impact of forward trading on spot market decisions, potential for exercising market power of the four dominant electricity producers has been found. Assuming Cournot behavior in the spot market...

Price volatility analysis has been reported in the literature for most competitive electricity markets around the world. However, no studies have been published yet that quantify price volatility in the Ontario electricity market, which is the focus of the present paper. In this paper, a comparative volatility analysis is conducted for the Ontario market and its neighboring electricity markets....

In this paper, we conduct numerical experiments based upon the oligopolistic model of electricity market proposed in [1]-[2] and applied to the German electricity market. Presently, the German electricity market is shaped by strategic behavior of energy firms so that a perfect competition market has not been reached as yet. An oligopolistic market structure emerges from the analysis and is char...

The main goal of MASCEM – Multi-Agent Simulator of Competitive Electricity Markets, is to give electricity market entities a tool to support their decisions and to obtain knowledge about market behaviour and evolution. Intelligent agents with strategic behaviour represent entities from electricity markets. In this paper we propose some illustrative scenarios to explain and take some conclusions...

a r t i c l e i n f o JEL classification: D82 D83 Q49 L11 L12 L94 Keywords: Price pass-through Norwegian electricity market Price asymmetry Market power Transmission lag In this paper we estimate the pass-through of wholesale electricity price to the end consumer price with variable price contracts in the Norwegian electricity market using weekly data. We find substantial asymmetry when retaile...

Electricity market liberalization aims to boost competition at the level of each member state as well as within the European Union (EU). Therefore, observing the strategic behavior of the market players (e.g. related to net access, cooperation or refusal to collaborate, etc.) becomes crucial. There are different mathematical models for describing the behaviour of a competitive market. For the s...
