The Integrated Energy and Climate Protection Program of the German government includes the political target of doubling the share of combined heat and power generation (CHP) in Germany from currently about 12% to 25% by 2020. In order to reach this goal, a new CHP law was enacted to improve the...

Fuzzy sets theory is proposed as an alternative to the probabilistic approach for assessing portfolios of power plants, in order to capture the complex reality of decision-making processes. This paper presents different fuzzy portfolio selection models, where the rate of returns as well as the...

Today's European utilities not only focus on electricity supply, but also offer exchange-traded “structured products” or portfolio management for unbundling financial and physical risk positions. Many utilities are only able to provide these services inside of their home markets, but in the...

The aim of this study is to analyze the impact of credit risk mitigation via margining on the optimal portfolio selection for power plants. We develop a model to estimate margining cashflows that is based on the clearing framework of the European Commodity Clearing AG (ECC), on stochastic...

The EU Directive 2004/8/EC concerning the promotion of cogeneration established principles on how EU member states can support combined heat and power generation (CHP). Up to now the implementation of these principles into national law has not been uniform and led to the adoption of different...

In this paper, we investigate existing and possible future power generation capacities in Switzerland from a risk-return perspective, using the Mean-Variance Portfolio Theory of Markowitz (1952). The study covers power generation technologies currently in operation, such as nuclear power,...

The Integrated Energy and Climate Protection Program of the German government includes the political target to double the share of combined heat and power generation (CHP) in Germany from currently about 12% to 25% in 2020. In order to reach this goal a new CHP law was enacted to improve the...

In this paper, we design and evaluate eight different strategies for hedging commodity price risks of industrial cogeneration plants. Price developments are parameterized based on EEX data from 2008-2011. The probability distributions derived are used to determine the value-at-risk (VaR) of the...

The aim of our research is to test and evaluate the technical indicators and oscillators, which are commonly used on other stocks and commodity markets (e.g. moving averages, stochastic oscillator, etc.) in terms of their efficiency at the present European natural gas virtual trading points...

In this paper we apply fuzzy set theory to the portfolio optimization of power generation assets, using a semi-mean absolute deviation (SMAD) model as a benchmark and a fuzzy semi-mean absolute deviation (FSMAD) model for comparison. The two models are applied to five onshore wind power plants...
