Abstract

Day-of-the-week persistence and seasonality of electricity prices in Spain, spanning 01/01/2006 to 04/11/2021, are investigated by employing updated fractional persistence frameworks in nonlinear settings. The results show marginal higher persistence in electricity prices during the working days (Tuesday, Wednesday, Thursday and Friday), compared to weekend days. In all cases, electricity prices are mean-reverting with long-range dependence properties. Results also show that the monthly electricity price series contain no seasonal effect.
