Zero-Shot Foundation Models for Day-Ahead Electricity Price Forecasting
Pretrained time-series and tabular foundation models (Chronos-2, Moirai-2, TimesFM-2.5, TabPFN, Mitra) can forecast day-ahead electricity prices in zero-shot mode, without market-specific training, using in-context learning over price history and exogenous load, renewable and fuel inputs. Students learn why only the prior-fitted tabular TabPFN family beats strong electricity-price benchmarks on MAE, RMSE and CRPS across markets, and why lower statistical error does not guarantee higher battery-arbitrage profit once a trader's risk appetite enters the decision.
