Traditional optimisation techniques when modeling energy systems seek to minimize cost and/or GHG emissions. However, investment decisions from an investor’s perspective not only seek to invest in the least-cost options but on least-risk characteristics of the electricity portfolio.
My research focuses in including financial portfolio theory as an additional proxy for assessing optimised electricity generation portfolios. This would lead to having not only a single or a deterministic set of optimal scenarios but a whole range of cost-risk Pareto efficient portfolios that allows the policy maker to choose according to his/her risk seeking characteristics.
Applied to developing countries this approach brings new criteria for analysing the impact of the uncertainty of climate change and the risk of cost overruns of large infrastructure. I use a TIMES energy system optimisation model for the Republic of Ecuador and include risk parameters in the objective function to account for uncertainty.
