Scenario Summary
Tornado reads the same shared scenario already used by Core Analysis and Monte Carlo. Assumptions stay read-only here so the sensitivity view remains anchored to Scenario Setup.

Shared Source Context
This page does not create a separate assumptions source. To change project, timing, or financing inputs, return to Scenario Setup.
A deterministic Core run is not required first. Tornado runs directly from the current shared Scenario Setup state.
Blocking issues
Analysis years must be greater than 0.
Construction periods must be 0 or greater.
COD period must be 0 or greater.
Discount rate must be entered in decimal form between 0 and 1.
Total capex must be greater than 0.
Annual revenue must be 0 or greater.
Annual opex must be 0 or greater.
Run Tornado
Configure the returned metric, select the value drivers to test, override ranges where needed, and run the current shared scenario.
Run Status
Scenario not ready
Latest Tornado Run
No run yet
Latest Core Reference
None
Tornado stays idle until the shared Scenario Setup state is complete and supported sensitivity inputs are available.
Selected Result Metric
Returned metric for the current Tornado run.
Selected Drivers
One or more supported value drivers can be included in the same run.
Range Behaviour
Each selected driver uses the standard range unless custom bounds are enabled for that driver.
Authoring Controls
Choose the result metric and the supported drivers to include in the next Tornado run.
Selected Drivers
Choose one or more supported drivers. Debt-linked inputs remain available only when financing inputs are present in the shared scenario.
Current Setup
Compact summary of the next run configuration.
| Driver | Range |
|---|---|
| Selected metric | Project NPV |
| Capex | Default: -10% to +10% |
| Revenue | Default: -10% to +10% |
| Opex | Default: -10% to +10% |
| Discount Rate | Default: -10% to +10% |
Only enabled drivers affect the current Tornado run.
Per-Driver Range Controls
Ranges define +/- shocks applied to each driver for sensitivity analysis.
| Driver name | Enabled | Mode | Low value | High value | Reset |

Tornado Results
Main readout shell for the latest returned Tornado outputs. This section remains read-only and presents the latest successful run in a committee-readable format.
idle
Tornado Status
Scenario not ready. Tornado stays idle until the shared Scenario Setup state is complete and supported sensitivity inputs are available.
Run Tornado to populate the returned summary cards for the selected metric and driver set.
Key Drivers / Tornado Visual
The main one-way sensitivity visual will appear here after the current shared scenario is run.
Run Tornado to populate the ranked driver visual using the returned backend sensitivity results.
