Wastewater Energy Island Resilience Package

Calculates source-bound wastewater energy island metrics from a deterministic SSC-17 task-owned source pack. The template combines oxygen demand, blower energy, biogas CHP, BESS autonomy, critical-process energy, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:
All source-pack values given for the SSC-17 wastewater energy island package
medium:
All source-pack values given for the SSC-17 wastewater energy island package
hard:
All source-pack values given for the SSC-17 wastewater energy island package
