Forecasting electricity prices in nowadays competitive electricity markets is a must for both producers and consumers because both need price estimates to develop their respective market bidding strategies. This paper proposes different transfer function models to predict electricity prices based on both past electricity prices and demands, and discuss the rationale to build them. The importance of electricity demand information is assessed. Appropriate metrics to appraise prediction quality are identified and used. Realistic and extensive simulations based on data from the PJM Interconnection for year 2003 are conducted. The models proposed are compared with naïve and other techniques.
