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.
