Webster Electric Coop

What This Utility Data Tells You

Webster Electric Coop is a member-owned electric cooperative operating in Missouri under EIA identifier 20318. It reports service to approximately 19,350 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 19 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 Webster Electric Coop customer experienced 167.0 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI — the average number of outage events per customer — was 1.20 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 118.0 minutes — the gap between that figure and the headline 167.0 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Webster Electric Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 99.9 to 167.0 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.
