Time availability

The time availability is a key figure for the energy industry and is determined as the quotient of the availability time of a thermal power plant and the calendar time . It thus represents the ratio of the availability of a power plant as the ratio of the operating and reserve time to the calendar time. It is calculated without taking into account underperformance during the operating time.

${\displaystyle k_{t}={\frac {t_{v}}{T_{N}}}={\frac {t_{N}-t_{NV}}{T_{N}}}}$

k _t is the time availability, t _V the availability time and t _N the nominal time. t _NA is the unavailability time.

On the basis of the work availability of a plant, it can be determined how much work a plant can perform based on its technical and operational condition, based on a period of time. The work availability is always less than the time availability.
