5.1Assumptions
Scenario SCN-SR02-PWR-01: what is assumed, and what is held constant.
- Baseline
- the 2026 reference state in this edition
- Drivers
- a regional power loss during a heat wave, coinciding with a software or cloud outage at a shared vendor
- Analogues
- Iberian blackout, 2025; global software outage, 202414
- Interventions
- none modelled: the specification describes the unmitigated case
- Run state
- narrative specification; quantified run scheduled for 2027
5.2The cascade, step by step
- 1
ENE → INF
voltage and frequency events trip generation; the grid separates
2025
- 2
INF → DAT
exchanges and data centres run on batteries and generators
2025
- 3
DAT → INF
a vendor outage removes remote management and payment services
2024
- 4
INF → WAT
pumping and treatment stop or run on reserves
2026
- 5
INF → HLT
hospitals move to emergency power; dispatch and records degrade
2024 · 2025
- 6
INF → FIN
payments and markets pause; losses accumulate
2024
5.3The scenario as a table of steps
How the shock in scenario SCN-SR02-PWR-01 would travel through Critical Infrastructure and Lifeline Systems‘s coupled systems, step by step, under the assumptions the edition states.
| Step | What happens | Source |
|---|---|---|
| 01 Energy to infrastructure | Voltage and frequency events trip generation; the grid separates. Analogue or source: 2025. | Edition SR-02, scenario SCN-SR02-PWR-01, step 1 |
| 02 Infrastructure to dat | Exchanges and data centres run on batteries and generators. Analogue or source: 2025. | Edition SR-02, scenario SCN-SR02-PWR-01, step 2 |
| 03 DAT to infrastructure | A vendor outage removes remote management and payment services. Analogue or source: 2024. | Edition SR-02, scenario SCN-SR02-PWR-01, step 3 |
| 04 Infrastructure to water | Pumping and treatment stop or run on reserves. Analogue or source: 2026. | Edition SR-02, scenario SCN-SR02-PWR-01, step 4 |
| 05 Infrastructure to health | Hospitals move to emergency power; dispatch and records degrade. Analogue or source: 2024 · 2025. | Edition SR-02, scenario SCN-SR02-PWR-01, step 5 |
| 06 Infrastructure to finance | Payments and markets pause; losses accumulate. Analogue or source: 2024. | Edition SR-02, scenario SCN-SR02-PWR-01, step 6 |
