Navasota Valley Elec Coop, Inc is a member-owned electric cooperative operating in Texas under EIA identifier 16146. It reports service to approximately 21,275 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 16 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 Navasota Valley Elec Coop, Inc customer experienced 3968.8 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. The SAIFI figure, which tracks average outage events per customer, came in at 4.92 for the same period, meaning customers statistically saw about 5 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 1079.7 minutes; the difference from the headline 3968.8 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Navasota Valley Elec Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 416.6 to 3968.8 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
