Capacity factor is location- and weather-dependent, and not always known for certain with a new technology (or in this case a known technology this much larger)

Capacity factor is location- and weather-dependent, and not always known for certain with a new technology (or in this case a known technology this much larger). Concentrated solar thermal also allows for storage, making the capacity factor percentage adjustable, and allowing for on-peak optimization, which would have a lower capacity factor but a significantly higher benefit to the power company.
