Abstract
Commodity and electricity price models are motivated by the several unexpected evolutions that commodity prices have shown over the previous decades. Several models are based on the classic Black-Scholes model, which was one of the first to simulate the stochastic behaviour of commodity prices. However, as of today, these forecasting models show poor performance when tested in long-term horizons, especially when applied to electricity market prices. This work attempts to determine a way to provide a decent accuracy in long-term (one year or more) forecasts of the Spanish electricity market price using cointegration and vector error correction (VEC) models, alongside other variables, such as fuel spot prices and futures prices. These variables have been assessed in order to determine which factors contribute to this work’s purpose.
