Instead of SAIDI, Redeia publicly reports on other availability and service quality indicators better suited to the transmission business. The indicators publicly available in the Sustainability Report of Redeia are Grid availability; Energy not-supplied (ENS); and Average Interruption Time (AIT). Taking into consideration that Redeia, as transmission network operator, has no available data of the number of customers connected, the calculation method considered is: SAIDI= 100% - ASAI transmission grid equivalent percentage.
