Day-Ahead Electricity Price Forecaster for Netherlands (NL)

High-accuracy calibrated quantile LightGBM model for forecasting Netherlands price. Resolution: hourly intervals. Trained on multi-year data (2023–2026) from ENTSO-E, featuring multi-scale lags, cyclical encodings, and conformal calibration for well-calibrated 80% prediction intervals ($P10, P50, P90$).

Quickstart: Python Inference

import pandas as pd
from huggingface_hub import hf_hub_download
import joblib

# 1. Download model artifacts
model_path = hf_hub_download(repo_id="ORGANIZATION/netherlands-price-forecaster", filename="models.joblib")
models = joblib.load(model_path)

# 2. Predict P10, P50 (point), and P90 quantiles
X_test = pd.read_csv("sample_input.csv")
p10 = models[0.1].predict(X_test)
p50 = models[0.5].predict(X_test)
p90 = models[0.9].predict(X_test)

print("Forecast Point Estimate:", p50[:5])
print("80% Lower Bound (P10):", p10[:5])
print("80% Upper Bound (P90):", p90[:5])
