Resolves conflicts between resilience and commercial dispatch.
BESS & Microgrids · Applied exercise
Draft a BESS sizing basis
A facility wants resilience and peak shaving but has provided only monthly bills. Define the evidence and first calculation model.
- 01Record the evidence
- 02Name assumptions and risks
- 03Choose the decision gate

WorkbookEducational exercise
Record the evidence, then score it.
Four required inputs, three short syntheses and a four-part self-review. Save or download at any point; the review request opens when every item is complete.
Build the decision from the required inputs.
State what is known, what remains assumed and what evidence would change the decision.
Score the evidence, not the effort.
Use 0 when evidence is absent, 1 when it is only named, 2 when it is explained with a source or method, and 3 when it is strong enough to support the next decision.
Separates kW, kWh, duration, losses and usable window.
Identifies protection, islanding and site-engineering dependencies.
Defines sensitivity and an operating acceptance test.
MODEL-ANSWER GUIDANCECompare your structure after completing the exercise.+
Declare resilience reserve as the primary constraint and peak shaving as secondary.
Model PCS kW and battery kWh from interval data, duration, efficiency, SOC window and end-of-life capacity.
Hold islanding, protection and fire strategy for approved engineering and authority review.
Reproduce actual tariff bills and run degradation, downtime and tariff sensitivities.
Finish 13 requirements before requesting review.
You can save or download an incomplete draft at any time. The review request becomes available only when every required response and self-review score is complete.
