Monte Carlo Simulations

Definition

Monte Carlo simulations are a statistical technique used to model the probability of different outcomes in processes that cannot easily be predicted due to the intervention of random variables. This method relies on repeated random sampling to calculate results, helping analysts understand the impact of risk and uncertainty in forecasting scenarios such as energy production and costs, including the levelized cost of electricity.
