The promotion of electricity from renewable energies in Germany causes difficulties in the profitable operation of many modern conventional power plants. Nevertheless, fluctuating availability of power from renewable energy sources requires flexible conventional plants, i.e. power plants which...

The liberalization of the energy markets and the merit order effect lead to difficulties in the operation even of modern, highly energy-effcient conventional power plants ('missing money problem'). Their operation often becomes unprofitable, so that sometimes the only remaining option is to...

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...

In this paper we develop a decision tool that is based on real options analysis and that supports flexibility investment decisions concerning conventional lignite-fired power plants. The value of the power plant is influenced both by technical and economic variables, the latter including...

This paper investigates whether coal- or biomass-fired Integrated Gasification Combined-Cycle (IGCC) power plants can serve as an economically viable future technology for providing clean electricity and heat in Germany. In the context of CO2 emission reduction in power generation, energy...

We study the economic viability and optimal sizing and siting of a hybrid plant that combines a ringwall hydro storage system with wind and solar power plants (ringwall storage hybrid power plant, RSHPP). A real options model is introduced to analyze the economics of an onshore RSHPP, and in...
