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.

EXPECTED DELIVERABLEA sizing-basis note with use-case priority, required data, power/energy equations, reserve, efficiency, degradation and acceptance measures.

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.

PART 1 · EVIDENCE AND ANALYSIS

Build the decision from the required inputs.

State what is known, what remains assumed and what evidence would change the decision.

PART 2 · PROFESSIONAL SELF-REVIEW

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.

Use-case priority

Resolves conflicts between resilience and commercial dispatch.

Score Use-case priority
Calculation

Separates kW, kWh, duration, losses and usable window.

Score Calculation
Safety boundary

Identifies protection, islanding and site-engineering dependencies.

Score Safety boundary
Commercial test

Defines sensitivity and an operating acceptance test.

Score Commercial test
Score all criteria

Choose one evidence status for every criterion. A result appears only after all criteria are scored.

MODEL-ANSWER GUIDANCECompare your structure after completing the exercise.+
01

Declare resilience reserve as the primary constraint and peak shaving as secondary.

02

Model PCS kW and battery kWh from interval data, duration, efficiency, SOC window and end-of-life capacity.

03

Hold islanding, protection and fire strategy for approved engineering and authority review.

04

Reproduce actual tariff bills and run degradation, downtime and tariff sensitivities.
