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) |

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.
