Homer Electric Assn Inc is a member-owned electric cooperative operating in Alaska under EIA identifier 19558. It reports service to approximately 33,816 customer accounts and generated about $0.11 billion in annual electric revenue, with a service footprint spanning 12 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 Homer Electric Assn Inc customer experienced 851.2 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. SAIFI — the average number of outage events per customer — was 3.88 for the same period, so customers statistically faced roughly 4 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 334.2 minutes — the gap between that figure and the headline 851.2 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Homer Electric Assn Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 474.9 to 851.2 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.

SAIDI (System Average Interruption Duration Index) measures the average total minutes per year that a customer of Homer Electric Assn Inc experiences power outages. A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing Homer Electric Assn Inc's SAIDI to that benchmark shows whether this utility is above or below average.
Homer Electric Assn Inc serves approximately 33,816 customers in Alaska. Customer count can affect reliability metrics because larger utilities may face different infrastructure challenges compared to smaller ones.

SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
