AIT
an indicator of Average Interruption Time in the power transmission system; expressed in minutes per year, it is a product of 60 and energy not supplied (ENS) by the power system, divided by the average power supplied by the transmission system, expressed in MW.
ATC allocation metod
a method of capacity calculation and allocation on the border between systems or zones, where commercial volumes of capacity are offered on the basis of arrangements made between operators of two neighbouring bidding zones in the period prior to capacity allocation (i.e. before the capacity auction), taking into account physical properties of the zones and having regard to congestions and expected demand for trading capacity
