Guaranteeing a steady supply of electricity at any given time requires that our businesses employ modern technologies for power delivery and monitoring system reliability. Reliability is tracked by average number and duration of system interruptions per customer, weighted based on ownership adjusted EBITDA.
System Average Interruption Frequency Index (SAIFI) represents the average number of interruptions the average customer experiences annually. System Average Interruption Duration Index (SAIDI) represents the total minutes of interruption the average customer experiences annually.
Our distribution businesses have made system upgrades to improve power delivery and, as a result, overall customer interruptions and reliability continue on favorable trends. However, in 2012 we experienced an increase at two of our businesses. The increase experienced at IPL was in large part due to a significant weather event phenomenon called a 'derecho' which left millions of customers without power in an area stretching from the Upper Midwest into the Mid-Atlantic during the month of June. AES Sonel's higher SAIDI and SAIFI in comparison to other businesses are mainly due to longer collection periods and higher bad debt.
