Short-term forecasting of Italian gas demand

Forecasting natural gas demand is a key problem for energy providers, as it allows for efficient pipe reservation and power plant allocation, and enables effective price forecasting. We propose a study of Italian gas demand, with particular focus on industrial and thermoelectric components. To the best of our knowledge, this is the first work about these topics. After a preliminary discussion on the characteristics of gas demand, we apply several statistical learning models to perform day-ahead forecasting, including regularized linear models, random forest, support vector regression and neural networks. Moreover, we introduce four simple ensemble models and we compare their performance with the one of basic forecasters. The out-of-sample Mean Absolute Error (MAE) achieved on 2017 by our best ensemble model is 5.16 Millions of Standard Cubic Meters (MSCM), lower than 9.57 MSCM obtained by the predictions issued by SNAM, the Italian Transmission System Operator (TSO).

Italian residential gas demand forecasting

Natural gas is one of the most important energy sources in Italy: it fuels thermoelectric power plants, industrial facilities and domestic heating. Forecasting gas demand is a critical process for each energy provider, as it enables pipe reservation and stock planning. In this paper, we address the problem of short-term forecasting of residential gas demand, by comparing several statistical learning models, including Ridge Regression, Gaussian Processes, and Deep Neural Networks. We also present the preliminary steps of preprocessing and feature engineering. To the best of our knowledge, no benchmark is available for the task we performed, thus we derive a theoretical performance limit, based on the inaccuracy of meteorological forecasts. Our best model, a deep neural network, achieves an RMSE which is about double with respect to the performance limit.
