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.

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-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

Foundation draft. Revisit the lessons and evidence requirements.

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.
