For outages from 1-Jul-2015 to 19-Feb-2016, energy not supplied is calculated using average energy not delivered per customer per minute from ADMS data above multiplied
Unplanned Outages - Total number of unplanned outages N A by the customer minutes off supply. ActewAGL considers this reasonable as it is consistent with legislation (Annual RIN issued by the AER to ActewAGL 3rd February 2016) and
previous years experience (calculation methodology. It was not possible to use option (a) for this period due to IT systems (APPLY and TCS) not allowing the linking of actual
energy delivered (billing history) with customers connected to each feeder.
From 20-Feb-2016 onwards, energy not supplied is calculated using option (a) average consumption of customers interrupted based on their billing history. This data is
