Dynamic Power System Investment Modelingand AnalysisHans Ravn, RAM-løse edb, HansRavn@aeblevangen.dk, www.RAM-lose.dk.AbstractIn the perspective of the expected large structural changes of the energy system in thepresent century in relation to ambitious environmental goals it is essential to have a goodunderstanding of investment processes in energy technologies. This encompasses severalaspects such as uncertainty, e.g. with relation to technological development, to fuelprices and to future demands, investors’ preferences and the timing of investments.Moreover, to properly analyze the possible developments paths of the energy sector,energy system models seem essential.In the present paper some steps towards development of a suitable energy system modelfor that task is described and applied. More specifically, the paper describes theenhancement of the existing energy system model, Balmorel, with an investment modulethat handles endogenous investments in energy transformation technologies withemphasis on the linkage over time. Further, by permitting settings of the investmenthorizon (varying flexibly between myopic to full technology life-time) it allows theanalysis of various actors’ different requirements. This enhances and generalizes thepresent endogenous investments module, which is myopic in the sense that it handlesyears sequentially.The investment considerations and logic is documented in the paper, and basic propertiesof the model are derived and described. Further, it is implemented in the Balmorelmodel, and development paths for the Nordic electricity and combined heat and powersector are investigated. The emphasis is on variations of assumptions with respect to fuelprices, environmental targets and the attitude of investing companies with respect to paybacktime.Consequences of the various settings of handling of time linkage and investmentshorizons are presented and analyzed. The analysis topics include consequences forelectricity prices, possibilities and costs of investment timings, and environmentalaspects.1 IntroductionThe energy sector plays a key role in the environmental policies in the EU andelsewhere. It is expected that large structural changes of the energy sector will take placein the present century in relation to ambitious environmental goals. Due to the large timehorizons of the investments to be undertaken the investigation of future – or moreappropriately of possible futures- is essential. The changes are governed by a mixture ofpublic planning (using various instruments such as taxes, support, regulation and others)and private decisions on investments and operation.One way of properly analyzing the possible developments paths of the energy sector is touse energy system models. Many such models exist, here one such model, Balmorel, willbe described, in particular in relation to its investment capabilities, including a newfeature for providing a more dynamic perspective on investments.Risø International Energy Conference 2011 Proceedings Page 151
