Analyzing price data from sequential German electricity markets, namely the day-ahead and intraday auction, a puzzling but apparently systematic pattern of price premiums can be identified. The price premiums are highly correlated with the underlying demand profile. As there is evidence that...

The paper at hand examines the power system costs when a coal tax or a fixed bonus for renewables is combined with CO2 emissions trading. It explicitly accounts for the interaction between the power and the gas market and identifies three cost effects: First, a tax and a subsidy both cause...

Nuclear power is an important pillar in electricity generation in France. However, France's nuclear power plant fleet is ageing, and the possibility of reducing its share in power generation or even a complete phaseout has been increasingly discussed. Our research therefore focuses on three...

The prevalent market structures found in many resource markets consist of a high concentration on the supply side and a low demand elasticity. Market results are therefore frequently assumed to be an outcome of strategic interaction between producers. Common models to investigate the market...

In liberalized power systems, generation and transmission services are unbundled, but remain tightly interlinked. Congestion management in the transmission network is of crucial importance for the efficiency of these inter-linkages. Different regulatory designs have been suggested, analyzed and...

The economic and ecological performance of OECD countries over two decades is measured by employing a Malmquist-Luenberger productivity index. The index credits the expansion of goods (value added) and the contraction of bads (emissions), at given inputs. We consider the inputs of capital,...

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...

The common application of EUGAS, a long-term, dynamic, interregional linear optimization model, is the projection of European natural gas supply up to 2030. Based on current expectations regarding future demand, supply costs and reserves, the model results comprise production and transport...

This paper analyzes the effects of start-up costs of different technologies in providing electricity power. We explicitly solve a simplified linear formulation of the dispatch problem. Transforming this primal problem, we show that dominated technologies should be used only in the case of...

Europe's increasing import dependency in natural gas facilitates a number of new infrastructure projects. However, up to now it has always been diffcult to assess the full impact of these projects as interdependencies within the whole European gas infrastructure system were hard to predict. We...
