# FBMC Flow-Based Market Coupling Forecasting API

Zero-shot electricity cross-border flow forecasting for 38 European FBMC borders using Amazon Chronos-2.

## 🚀 Quick Start

This HuggingFace Space provides a **Gradio API** for GPU-accelerated zero-shot forecasting.

### How to Use (Web Interface)

1. **Select run date**: Choose the forecast date (YYYY-MM-DD format)
2. **Choose forecast type**:
   - **Smoke Test**: 1 border × 7 days (~30 seconds)
   - **Full Forecast**: All 38 borders × 14 days (~5 minutes)
3. **Click "Run Forecast"**
4. **Download results**: Parquet file with probabilistic forecasts

### How to Use (Python API)

```python
from gradio_client import Client

client = Client("evgueni-p/fbmc-chronos2")
result_file = client.predict(
    run_date="2025-09-30",
    forecast_type="smoke_test"
)

# Download and analyze locally
import polars as pl
df = pl.read_parquet(result_file)
print(df.head())
```

## 📊 Dataset

**Source**: [evgueni-p/fbmc-features-24month](https://huggingface.co/datasets/evgueni-p/fbmc-features-24month)

- **Rows**: 17,880 hourly observations
- **Date Range**: Oct 1, 2023 - Oct 14, 2025
- **Features**: 2,553 engineered features
  - Weather: 375 features (52 grid points)
  - ENTSO-E: ~1,863 features (generation, demand, prices, outages)
  - JAO: 276 features (CNEC binding, RAM, utilization, LTA, net positions)
  - Temporal: 39 features (hour, day, month, etc.)

- **Targets**: 38 FBMC cross-border flows (MW)

## 🔬 Model

**Amazon Chronos 2** (120M parameters)
- Pre-trained foundation model for time series
- Zero-shot inference (no fine-tuning)
- Multivariate forecasting with future covariates
- Dynamic time-aware data extraction (prevents leakage)

## ⚡ Hardware

**GPU**: NVIDIA A10G (24GB VRAM)
- Model inference: ~5 minutes for complete 14-day forecast
- Recommended for production workloads

## 📈 Performance Target

**D+1 MAE Goal**: <150 MW per border

This is a zero-shot baseline. Fine-tuning (Phase 2) expected to improve accuracy by 20-40%.

## 🔐 Requirements

Set `HF_TOKEN` in Space secrets to access the private dataset.

## 🛠️ Technical Details

### Feature Availability Windows

The system implements time-aware forecasting to prevent data leakage:

- **Full-horizon D+14** (603 features): Weather, CNEC outages, LTA
- **Partial D+1** (12 features): Load forecasts (masked D+2-D+14)
- **Historical only** (1,899 features): Prices, generation, demand

### Dynamic Forecast System

Uses `DynamicForecast` module to extract context and future covariates based on run date:
- Context window: 512 hours (historical data)
- Forecast horizon: 336 hours (14 days)
- Automatic masking for partial availability
