Site Suitability Analytics

Fusing multi-source satellite data to rank and qualify candidate renewable energy sites by solar irradiance, wind resource, terrain, land cover and grid proximity.

Governments and developers selecting sites for utility-scale solar and wind projects are making 25-to-40-year capital commitments, yet most still rely on sparse ground-station networks, third-party modelled datasets and commercially licensed indices that can be withdrawn, repriced or withheld at will. The gaps are consequential: a poorly sited 500 MW solar farm that underperforms its P50 estimate by 8% costs hundreds of millions in lost revenue and stranded debt over its lifetime. Satellite data — multispectral, SAR, lidar-derived DEM and hyperspectral — removes the ground-station blind spot and provides consistent, revisitable baselines for every candidate parcel in a national territory.

A sovereign constellation built for this role integrates at least three payload types: a multispectral imager for land-cover classification and albedo mapping, a thermal-infrared channel for surface energy balance estimates, and a passive microwave or SAR payload for soil moisture and terrain roughness. Cross-registered with reanalysis wind fields and open DEM products, these inputs feed a site-scoring pipeline that ranks every 10-hectare parcel in the country against a common, auditable methodology. The output is not a commercial product locked behind a licence agreement — it is a national planning layer owned and updated by the state.

The operational outcome is faster permitting, lower pre-development survey costs and a defensible evidence base for zoning decisions. Nations that control this pipeline can update scores quarterly, flag land-cover change before a site breaks ground, and share data with developers under terms the state sets — rather than paying a foreign vendor to score their own territory and accepting whatever resolution or update cadence that vendor chooses to offer.

What matters

A 1% improvement in irradiance estimation accuracy translates directly to tighter debt covenants and lower cost of capital for utility-scale projects.
Commercial site-scoring products use proprietary algorithms and can be withdrawn or restricted under export-control or geopolitical pressure without notice.
Terrain ruggedness, slope aspect and soil drainage — all satellite-derivable — determine civil works cost more reliably than any ground survey at pre-feasibility stage.
Zoning disputes and environmental objections are won or lost on evidence quality; a sovereign, court-admissible satellite baseline is a litigation asset.

Sovereignty score: 8/10 — A nation that cannot independently score its own territory for renewable potential cedes the strategic agenda of its energy transition to whoever controls the data.

Foreign commercial siting platforms operate under jurisdiction-specific export-control regimes; a host government can be denied updated data or fine-resolution products at the moment of a geopolitical dispute, freezing national energy planning.
Third-party site scores embed proprietary irradiance and wind models that cannot be audited, creating legal and regulatory risk when developers challenge zoning decisions or lenders dispute P50 estimates in arbitration.
Sovereign control of the scoring methodology allows the state to set minimum thresholds for biodiversity impact, grid connection cost and community consultation as first-class inputs — not retrofitted filters on a vendor's product.
Domestic satellite-derived baselines become a recurring public asset updated quarterly, eliminating the per-query licensing fees that currently price smaller nations out of high-resolution pre-feasibility analysis for rural and offshore areas.

Reference architecture

Payload: Three-payload stack per satellite: (1) multispectral imager, 8 bands 400–2500 nm, 5m GSD, 40 km swath for land-cover and albedo mapping; (2) thermal-infrared channel, 60m GSD, 8–12 µm for surface energy balance; (3) X-band SAR, 10m GSD, 50 km swath for terrain roughness and soil moisture under cloud cover
Bus class: ESPA-class microsat, 150–200 kg, 900W total power, deployable solar panels, 3-axis stabilised to 0.01° pointing for consistent cross-track registration between payload channels
Orbit: Sun-synchronous LEO at 520–550 km, 10:30 local time descending node for consistent solar illumination; 6-satellite constellation achieving 3-day global revisit, 1-day revisit for national territory
Ground segment: 2-station national network (X-band downlink at 1.2 Gbps, S-band TT&C); secondary reception agreement with a regional partner station for redundancy; SatNOGS UHF/VHF backup for housekeeping telemetry
