What mid-pack Webster Electric Coop filings show

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. 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 Webster Electric Coop customer experienced 167.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. The SAIFI figure, which tracks average outage events per customer, came in at 1.20 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 118.0 minutes, and the spread against the headline 167.0 indicates how much weather, versus routine infrastructure, drove the outage total.

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 climbed from 99.9 to 167.0 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
