Electric utilities serving Dimmit County, Texas
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
3 utilities list Dimmit County, Texas, in the service territory they reported to EIA for 2024, the largest by residential customers statewide being Medina Electric Coop, Inc, Rio Grande Electric Coop, Inc and AEP Texas Central Company.
Their average residential prices ran from 12.10¢ to 18.51¢ per kilowatthour, with a median of 15.31¢, against a Texas average of 14.94¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Texas customers, not for this county alone.
AEP Texas Central Company lists the county too but reported no residential sales in Texas under its own name: in the competitive part of Texas the distribution company delivers the power while retail electric providers bill the customer, and EIA does not publish those providers' customers by county.
The median SAIDI they reported was 235.2 minutes per customer including major event days; the median among all Texas utilities reporting was 200.2.
The Census Bureau estimates the county's population at 8,024. EIA does not publish customers by county, so which utility serves a given address has to be confirmed with the utility or the state utility commission.
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Figures are for each utility's whole Texas operation; EIA publishes nothing at county level.
