City of Lafayette - (LA) is a municipally-owned utility operating in Louisiana under EIA identifier 9096. It reports service to approximately 71,521 customer accounts and generated about $0.20 billion in annual electric revenue, with a service footprint spanning 11 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average City of Lafayette - (LA) customer experienced 41.7 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 0.62, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 20.4 minutes, and the spread against the headline 41.7 indicates how much weather, versus routine infrastructure, drove the outage total.
City of Lafayette - (LA) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that window, SAIDI moved from 1054.4 down to 41.7 minutes, a trend worth noting for anyone weighing capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against City of Lafayette - (LA)'s other reported years.
