Enefit Prosumer Forecasting

Forecasting the energy behaviour of prosumers from large-scale smart-meter data, with weather and time-series feature engineering feeding a gradient-boosting pipeline.

Overview

A forecasting model for the energy behaviour of prosumers, customers who both consume and generate electricity. Built at Wageningen in January 2024 on large-scale smart-meter data.

The problem

Prosumers make grid balancing harder. A household with solar panels is a load for part of the day and a supplier for another part, and the switch depends on weather, season and behaviour at once. Imbalance costs money, so a forecast that is wrong in a predictable direction is worse than useless.

What I did

  • Engineered time-series and weather features over large-scale smart-meter data.
  • Built a gradient-boosting pipeline using LightGBM and CatBoost.
  • Set up cross-validation with early stopping and tuned hyperparameters against mean absolute error.
