Active Data Sources
| Source | Status | Last Fetch | Freshness | Plants Using | Notes |
|---|---|---|---|---|---|
| Open-Meteo (ECMWF IFS + ICON + GFS) | Active | — | — | all | FREE tier or €29/mo commercial |
| NASA POWER (MERRA-2 Kt) | Active | — | — | training only | FREE, 1-2 day lag |
| NOAA METAR (aviation obs) | Active | — | — | all | FREE, 30-min cadence |
| ECMWF Open Data (direct) | Standby | — | — | fallback | FREE, used if Open-Meteo stale > 6 hr |
| MOSDAC INSAT-3DR | Pending registration | — | — | 0 | FREE w/ registration • 4 km India GHI |
| Solcast (DNV) — premium | Optional | — | — | 0 | Paid, recommended for >25 MW plants |
Fallback Cascade (FRD §15.2)
- Primary: Open-Meteo live (flag:
GOOD) - L1: Cached Open-Meteo < 6 hr old (flag:
NWP_STALE) - L2: ECMWF Open Data direct (flag:
NWP_SOURCE_SWITCH— MOS bias recalibrated) - L3: Climatology from historical SCADA (flag:
CLIMATOLOGY_ONLY— red alert fires)
Every forecast row carries exactly one data_quality_flag for DSM-dispute provenance.
🛰️ Solar & Wind Asset Detection
Geodatabase of detected RE assets from satellite + drone imagery
FRD §14 Solar Asset Detection • §17 Wind Turbine Detection
This module runs YOLOv8-seg + SAM2 on Sentinel-2 / Planet / WorldView / drone imagery to detect
solar panels and wind turbines. Results land in solar_assets and wind_assets
PostGIS tables.
For Phase-1 pilot, detection runs on demand via
POST /api/v1/solar-assets/detection-job (admin role).
Aggregate capacity feeds the BtM correction layer in the forecast engine
(FRD §14.8), improving portfolio MAPE by 1–2% in high-rooftop-density zones.

💰 Data Vendors & Cost Efficiency
Free-first vendor stack with paid upgrade only when DSM savings justify
See docs/VENDORS.md for full analysis and per-plant ROI scenarios
Recommended Stack
| Layer | Vendor | Cost | Why |
|---|---|---|---|
| NWP primary | Open-Meteo | FREE / €29/mo | ECMWF IFS 9 km + ICON + GFS + AIFS in one API; no key; <10ms |
| NWP backup | ECMWF Open Data | FREE | Direct source, independent fallback, CC-BY 4.0 commercial OK |
| Satellite irradiance | MOSDAC INSAT-3DR | FREE w/ reg | ISRO, 4 km India, 30-min cadence, mandated by FRD §4.2 |
| Historical Kt | NASA POWER | FREE | MERRA-2 clearness index for training; 1-2 day lag |
| Aviation obs | NOAA METAR | FREE | 30-min visibility + cloud at 15+ Indian airports |
| Premium solar | Solcast (DNV) | Quote | 25-50% better than NWP; enable only if DSM > subscription |
| Premium wind | Meteomatics | Quote | EURO1k 1 km downscaling for complex terrain |
| Fallback simple | Visual Crossing | $35/mo | Cheapest metered API; weak on radiation, good for temp/wind |
| ❌ Not used | OpenWeatherMap | n/a | Low-res GFS derivation; tight rate limits; no cost advantage |
Monthly Cost Scenarios
A. Pilot (5 plants, free only): ₹0/month • DA solar MAPE ~12–15% by month 3
B. Prod 50 plants (Open-Meteo commercial): ~₹2,700/month • MAPE 9–11% by month 6
C. Premium 100 plants incl. 20 big solar: ~₹2 lakh/month • DSM savings ~₹8–15 lakh/month
