Modeling Technology Adoption as an Irreversible Investment Under Uncertainty: The Case of the Turkish Electricity Supply Industry
This paper studies energy conversion technology adoption in the electricity supply sector from the perspective of irreversible investments under uncertainty, and with a particular interest in environmental sustainability. We develop a dynamic technology adoption model that is firmly rooted in economic theory and that takes important determinants of optimal investment in available technologies (e.g. life-cycle capital and operation cost) explicitly into account. Uncertainty is introduced for the demand for peak-load capacity, unit generation costs, and for the average electricity price. We test the model empirically by applying it to data for the Turkish power supply industry. The model-guided optimal investment results based on net present value considerations exhibit significant deviations from the actual investment outcome. We find that the increased adoption of natural-gas-fired power generation technologies in Turkey in recent years, while contributing to environmental sustainability, has had doubtful merits from an investor’s perspective.
