What mid-pack Palmetto Electric Coop Inc filings show

Palmetto Electric Coop Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 14398. It reports service to approximately 78,584 customer accounts and generated about $0.18 billion in annual electric revenue, with a service footprint spanning 27 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.

In 2023, the average Palmetto Electric Coop Inc customer experienced 170.6 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. The SAIFI figure, which tracks average outage events per customer, came in at 2.31 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 35.3 minutes, the gap between that figure and the headline 170.6 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Palmetto Electric Coop Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 88.4 to 170.6 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
