Systemic System Infrastructure Index

The First Open Digital Twin Fusing Grid Risk with Societal Exposure

A composite resilience score for OECD countries power grids — 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

Starting with Italy, Germany, France, Spain, United Kingdom, United States, Switzerland, Austria, Canada and Japan. Each country's digital twin uses the same SSI v4.0.2 methodology adapted to local data sources, enabling cross-border comparison and OECD country-level risk insights.
