Capacity factor is a crucial concept for understanding the potential output achievable by a power generator. Imagine a perfectly reliable device that runs 24 hours a day, 365 days a year at its full rated capacity. That device has a capacity factor of 100%. In the real world, the capacity factor is always less than 100, sometimes much less. Reasons might be:
- Mechanical breakdown or shutdown for maintenance
- Lack of demand for the electricity generated
- Intermittent or interrupted energy source
- Variability of the energy source
