By using time series of hourly spot prices and volumes of four European electricity markets, we show that the total traded volume has negligible impact in determining the volatility of electricity prices when spikes are excluded. This result is robust to the different econometric techniques...

We propose a simple univariate model for the dynamics of spot electricity prices. The model is nonparametric in the sense that it is free from parametric model assumptions and flexible in capturing the dynamics of the data. The estimation is performed in two steps. Preliminarily, spikes are...
