## Content Description
|
|
|
|
### What it contains
|
|
|
|
SMARD is the official electricity market data platform of the German Federal Network Agency (Bundesnetzagentur). It provides real-time and historical data on electricity generation, consumption, and market prices in Germany.
|
|
|
|
**Key data available:**
|
|
- **Stromerzeugung** by energy source (11 filter codes for generation)
|
|
- **Stromverbrauch** (total consumption, residual load)
|
|
- **Stromhandel** (import/export balances with neighboring countries)
|
|
- **Marktdaten** (spot prices, day-ahead, intraday)
|
|
- **Regelenergie** (balancing energy)
|
|
- Temporal resolutions: quarter-hour, hour, day, week, month, year
|
|
|
|
**Generation sources covered:**
|
|
- Wind Onshore (4067), Wind Offshore (1225), Photovoltaik (4068), Biomasse (4066)
|
|
- Wasserkraft (1226), Sonstige Erneuerbare (1228)
|
|
- Braunkohle (1223), Steinkohle (4069), Erdgas (4071)
|
|
- Kernenergie (1224), Sonstige Konventionelle (1227)
|
|
- Stromverbrauch Gesamt (410, separate category)
|
|
|
|
### Coverage
|
|
- Geographic: Germany (DE), plus neighboring market zones
|
|
- Temporal: 2015 to present (some historical data back to earlier)
|
|
- Data lag: typically 1-5 days for generation data; real-time for prices
|

## Substrate Relevance
|
|
|
|
### Problems Addressed
|
|
- **Energiewende Monitoring:** Official data for tracking Germany's energy transition — renewable share, coal phase-out progress, nuclear decommissioning.
|
|
- **PR-00002 (Structural Analysis):** Energy market structure affects economic and political power; fossil fuel dependence creates geopolitical vulnerabilities (Russia gas crisis 2022 demonstrated this acutely).
|
|
|
|
### Connection to DE-Plan
|
|
- **Energiewende (CHALLENGE):** Primary data source for measuring progress toward the 65% renewable target (2030) and 80% target (2035).
|
|
- **Kohleausstieg tracking:** Monthly data allows monitoring of coal phase-out trajectory vs. 2038 deadline.
|
|
|
|
### Dataset: DE-Energy-Mix ✅
|
|
|
|
Dataset implemented at `Data/DE-Energy-Mix/DE-Energy-Mix.md`.
|
|
|
|
**As of 2026-04-20 (FY2024):**
|
|
| Metric | Value |
|
|
|--------|-------|
|
|
| Renewable share | 60.2% |
|
|
| Total generation | ~428 TWh |
|
|
| Top source | Wind Onshore (24.9%, 107 TWh) |
|
|
| Coal share | 22.3% (Braunkohle + Steinkohle) |
|
|
| Nuclear share | 0.0% (decommissioned April 2023) |
|

## API / Access
|
|
|
|
- **Web portal:** https://www.smard.de/home/marktdaten (interactive charts and CSV download)
|
|
- **API (undocumented but stable):**
|
|
- Index: `GET https://www.smard.de/app/chart_data/{filter}/{region}/index_{resolution}.json`
|
|
- Timeseries: `GET https://www.smard.de/app/chart_data/{filter}/{region}/{filter}_{region}_{resolution}_{timestamp}.json`
|
|
- Regions: `DE`, `AT`, `LU`, `DE-LU`, `DE-AT-LU`, `50HzT`, `Amprion`, `TenneT`, `TransnetBW`, `APG`, `Creos`
|
|
- Resolutions: `quarterhour`, `hour`, `day`, `week`, `month`, `year`
|
|
- **Substrate fetch script:** `bun get-de-energy` — writes to `Data/DE-Energy-Mix/`
|
|
- **Auth:** None required for public data
|
|
- **Rate limit:** Not documented; sequential per-filter calls are well within limits
|
|
- **TLS note:** Bun on macOS may require `NODE_TLS_REJECT_UNAUTHORIZED=0` — embedded in fetch script
|
|
- **Last fetched:** 2026-04-20 — 11 generation sources, 2024 annual data

## Quality Assessment
|
|
|
|
| Dimension | Rating | Notes |
|
|
|-----------|--------|-------|
|
|
| **Completeness** | Very High | Official metered data from all grid operators; near-complete coverage |
|
|
| **Accuracy** | Very High | Regulatory reporting requirements; not self-reported |
|
|
| **Timeliness** | Very High | 15-minute resolution data, typically 1-5 day lag |
|
|
| **Comparability** | High | Consistent methodology since 2015; ENTSO-E compatible |
|
|
| **Access** | High | Free, no registration, stable undocumented API |
|
|
|
|
**Key limitation:** Erzeugungsdaten (generation) are gross figures; net consumption and import/export balances require separate filter codes. Self-consumption from small solar installations may be partially underreported.
