Grid-Scale Battery Energy Storage Systems worked example

Supplier Risk Score with severity of supply disruption impact on bess production of 23 score: a worked example in grid-scale battery energy storage systems

This scenario runs the supplier risk score calculation on the strong side: severity of supply disruption impact on bess production of 23 score, with every other input held at its documented default. Use it when ranking BESS cell or module suppliers in the supply chain risk register and you need a defensible supplier risk priority number to decide whether to qualify a second source or increase incoming inspection intensity.

The inputs for this scenario

  • Severity of supply disruption impact on BESS production: 23 score (raised for this scenario; the documented default is 9)
  • Frequency of supplier quality or delivery issues: 4 score (unchanged)
  • Detection effectiveness of incoming inspection and audits: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Supplier risk priority number = severity of disruption x frequency of issues x detection effectiveness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.35 score for bess supplier risk priority number, the number this scenario is built around.
  • At this operating point the engine returns 23 score for severity of supply disruption on bess production.
  • At this operating point the engine returns 4 score for frequency of supplier quality or delivery issues.
  • At this operating point the engine returns 3 score for detection effectiveness of incoming inspection and audits.

How this compares with the baseline

  • Against the tool's baseline example, where severity of supply disruption impact on bess production sits at 9 score and the headline result is 5.75 score, this scenario comes in 97.39% above the baseline at 11.35 score.
  • Use it when building a supply-chain risk register, prioritizing supplier audits, or justifying dual-sourcing and safety-stock decisions. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • BESS supplier risk priority number: 11.35 score (headline result)
