What long-outage Suwannee Valley Elec Coop Inc filings show

Suwannee Valley Elec Coop Inc is a member-owned electric cooperative operating in Florida under EIA identifier 18360. It reports service to approximately 28,992 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 26 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.

In 2023, the average Suwannee Valley Elec Coop Inc customer experienced 6825.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. Over the same period, SAIFI (outage events per customer) was 6.86, putting the typical customer at roughly 7 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 340.0 minutes, and the spread against the headline 6825.0 indicates how much weather, versus routine infrastructure, drove the outage total.

Suwannee Valley Elec Coop Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 335.0 to 6825.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
