Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2021, the average Greenwood Utilities Comm customer experienced 18.2 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. SAIFI, the average number of outage events per customer, was 0.08 for the same period, so customers statistically faced roughly 0 distinct interruptions that year.
The EIA dataset includes 2 years of continuous reporting (2020–2021) for Greenwood Utilities Comm, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 16.6 to 18.2 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Greenwood Utilities Comm's other reported years.
