Systemic System Infrastructure Index

The First Open Digital Twin Fusing Grid Risk with Societal Exposure

A composite resilience score for OECD countries power grids — plus Greenland (Kingdom of Denmark) — open data, open methodology, zero proprietary dependencies. Select a country to explore its digital twin.

Operated as a non-profit through a dedicated foundation — ensuring the Index serves the public interest.
Breaking the Silos

Power grid resilience is inseparable from its socio-economic context. The SSI fuses traditional grid metrics with socio-economic, environmental, and energy-transition data — all from public sources — to capture what single-discipline indices miss.

OECD Coverage

Now covering 23 OECD countries plus Greenland: Italy, Germany, France, Spain, United Kingdom, United States, Switzerland, Austria, Canada, Japan, Australia, Chile, Denmark, Norway, Finland, Poland, Sweden, Mexico, Greece, Turkey, Ireland, Portugal, New Zealand, and Greenland (autonomous territory within the Kingdom of Denmark — grid independent from Denmark's). Each country's digital twin uses the same SSI v4.0.2 methodology adapted to local data sources, enabling cross-border comparison and pan-OECD risk insights. Targeting full OECD membership coverage.
