Capacity Factor and Annual Generation Workspace
Estimate annual generation and test utilization, including standard and leap-year handling.
Annual generation equals rated MW multiplied by annual hours and capacity factor.

How the result was produced
- 100 MW × 8,760 h × 0.3
Professional application
Use the result to frame the next decision.
- Translate utilization into annual output.
- Check a forecast against installed MW.
- Compare utilization without confusing it with efficiency.
Worked case
Follow the units through one concrete example.
A 100 MW plant at 30% capacity factor produces 262,800 MWh in a 365-day year.
Exclusions
What this model deliberately leaves unresolved.
- Capacity factor is not efficiency.
- The output is not a production guarantee.
- Timing and captured value are not represented.
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 annual-generation 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.
