Biogas Sludge Generator Dispatch Package

Calculates source-bound biogas generator dispatch metrics from a deterministic SSC-10 task-owned source pack. The template combines volatile solids destruction, biogas and methane energy, generator electric energy, dispatch runtime, heat recovery, 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-10 biogas dispatch package
medium:
All source-pack values given for the SSC-10 biogas dispatch package
hard:
All source-pack values given for the SSC-10 biogas dispatch package

Scenario archetypes

Each generated task is drawn from one of these realistic scenario bands.

Site contexts ground each scenario in a real locale the model can use to infer hidden values.
