At a joint meeting of the New Orleans City Council’s Utility, Cable, Telecommunications and Technology (UCTTC) and Climate and Sustainability Committees last week on Wednesday, February 8, the Council adopted minimum electric reliability standards for Entergy New Orleans LLC.
The standards are based on calculations known as System Average Interruption Frequency Index and System Average Interruption Duration Index, or SAIFI and SAIDI. Essentially, these scores together indicate the average number of outages for a utility customer and the average length of time, in minutes, of those outages.
Under the standards as adopted by the Council, the initial SAIFI standard for ENO is 1.53, meaning the average customer should not experience more than approximately 1.5 outages annually (yes, you’re right, there’s no such as “half an outage”, but these are averages; basically, it means fewer than two outages per year). The SAIDI standard is 178.2, meaning that the average customer should not experience outages of longer than 178.2 minutes each year, or just under three hours.
Just as importantly, the standards provide a path toward improving reliability over time, requiring ENO to submit annual reports not only detailing its compliance, but also identifying the worst-performing portions of its distribution infrastructure and creating a plan to improve performance. ENO’s failure to make those improvements can result in an additional $500K penalty annually.
These standards must be refined and made more stringent over time. The Council must enforce them rigorously, and hold ENO accountable for failure to improve. When the Council’s paid advisors first presented these standards to the Council for consideration, they noted that ENO would have been in compliance for all but one of the past five years. The city has already experienced multiple fair-weather outages just since the beginning of 2023.
