Estimate cycle margin from MWh, spread, efficiency, cycling, degradation and operating cost.

CalculationMargin = MWh × cycles × spread × efficiency − degradation cost − operating cost

Cycle margin is efficiency-adjusted spread income less degradation and annual operating cost.

Live result

Indicative annual cycle margin

1,564,000EUR/year

This model does not forecast dispatch or prove that each entered spread can be captured.

Calculation trace

How the result was produced

  1. Annual discharged throughput: 30,000 MWh
  2. Efficiency-adjusted spread income less throughput degradation cost and annual operating cost.

Professional application

Use the result to frame the next decision.

  1. Screen cycle economics.
  2. Test efficiency and degradation.
  3. Separate energy margin from other revenues.

Worked case

Follow the units through one concrete example.

The model isolates cycle margin and does not assume every cycle captures the same spread.

Exclusions

What this model deliberately leaves unresolved.

  • Dispatch is simplified.
  • Availability is excluded.
  • Other revenue stacks are omitted.

Decision questions

Interpret the result before you use it.

These are the questions most likely to expose a wrong unit, inconsistent boundary or misleading commercial shortcut.

Can this BESS cycle-economics calculation replace a bankable model?

No. It is an educational screening calculation. A financeable conclusion requires project-specific evidence, documented assumptions, expert review and due diligence.

Are my inputs stored or shared?

No. Scenarios remain in this browser session and are not persisted to a project database.

How should gross and net values be handled?

Choose one measurement boundary, label it and keep it consistent across inputs and comparisons.

What should accompany an exported result?

Keep the source, date, units, boundary, scenario and every assumption that materially changes the conclusion.

Methodology and evidence

Inspect the basis before relying on the output.
