What short-outage Kerrville Public Utility Board filings show

Kerrville Public Utility Board is a municipally-owned utility operating in Texas under EIA identifier 28604. It reports service to approximately 24,105 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.

In 2023, the average Kerrville Public Utility Board customer experienced 57.3 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 0.92 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 36.2 minutes, and the spread against the headline 57.3 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Kerrville Public Utility Board, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 367.8 to 57.3 minutes across that span, a direction regulators and prospective customers tend to watch closely. 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 Kerrville Public Utility Board's other reported years.
