In this work, we explore the impact that intra-daily information could have on explaining and forecasting the conditional volatility of daily electricity returns. Returns are computed on Italian spot prices. The basic model considers an autoregressive structure on the conditional mean, daily...

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...

In the last few years we have observed an increasing interest in deregulated electricity markets. Only few papers, to the authors' knowledge, have considered the Italian Electricity Spot market since it has been deregulated recently. This contribution is an investigation with emphasis on price...

New results are presented relating to the integration of the French, German, British, Dutch and Spanish power markets at day-ahead, week-ahead, one month-ahead and two month-ahead lead times. Overall, there is evidence of market integration, increasing over time, despite an underlying...

We modelled electricity prices by fractionally integrated processes finding significant relations between zonal spot prices and exogenous variables. Day-ahead forecasts have been computed thanks to forecasted volumes and a scenario analysis

In the last few years we have observed deregulation in electricity markets and an increasing interest of price dynamics has been developed especially to consider all stylized facts shown by spot prices. Only few papers, to the authors' knowledge, have considered the Italian Electricity Spot...
