Tri-County Electric Cooperative rates per kWh and bills

A 19.1% jump in one year

Tri-County Electric Cooperative, registered with EIA as Tri-County Electric Coop, Inc (TX) (utility number 19159), is a member-owned co-op on the ERCOT grid that both supplies and delivers electricity to its members. Co-ops with the same name operate in other states; the figures here are for the Texas one only.

Its residential members paid an average of 12.65¢ per kWh² in 2024 and 15.07¢ per kWh¹ in 2025. Average revenue per kWh is what members were billed in total divided by the kWh they used, so it moves with base rates, fixed monthly charges and power-cost adjustments all at once, and EIA's data do not separate them. Among the other Texas utilities with a page here that sell full-service power, no change in the same two years came close:

In 2024 Tri-County's members paid less per kWh than CoServ's; a year later they paid more. Why the average rose is a question for the co-op's board decisions and published rate schedules: EIA collects revenue and sales, not the reasons behind them.

The co-op is not in the sample of Form EIA-861M, EIA's monthly utility survey, so 2025 is the latest year with an official average. Texas homes across all providers paid 15.98¢ per kWh⁴ over the 12 months September 2025 to August 2026 (2026 months preliminary); that statewide figure is context, not a Tri-County price.

Where 15.07¢ sits

After the increase, the co-op's 2025 average landed in the middle of most comparisons:

• In Texas: 11th highest of the 61 utilities with 10,000 or more bundled residential customers, and 2.1% below the Texas average (15.40¢ per kWh³, all providers). The range among those utilities ran from 9.42¢ per kWh at Kerrville Public Utility Board to 17.04¢ per kWh at Grayson-Collin Electric Cooperative.
• Among co-ops: 6.9% above the national average for electric cooperatives; Texas co-ops as a group averaged 13.17¢ per kWh.
• Nationally: 89th highest of 177 among utilities with 100,000 or more residential customers, whose median was 15.07¢ per kWh¹.

1,512 kWh a month: why the bill is high

The price explains only part of the bill. A Tri-County home used 1,512 kWh a month on average in 2025, up from 1,487 kWh in 2024. The Texas average was 1,110 kWh, and Texas already ranked 5th highest⁵ among the states for use per home. A higher price on slightly more kWh lifted the average bill from $188.12² to $227.78, +21.1%¹.

The comparison with the state shows how use drives the gap: Tri-County's 2025 average price was 2.1% below the Texas average, yet its average bill of $227.78¹ was well above the Texas figure of $170.95⁵. EIA's annual data do not say what the extra kWh go to; a household's own bill history is the better guide to where it stands against the co-op average.

16 counties, none served alone

EIA's 2025 territory records place Tri-County in 16 counties: Archer County, Baylor County, Denton County, Foard County, Haskell County, Hood County, Jack County, King County, Knox County, Palo Pinto County, Parker County, Stonewall County and 4 others. In 16⁶ of them at least one other distribution utility also reports customers, so a county, city or ZIP code does not settle who serves a home. The co-op's service-area map does, by address.

The neighbor determines what kind of bill a home gets. In Parker, Hood, Palo Pinto, Tarrant and Wise counties, among others, EIA's records list Oncor alongside the co-op; in Knox, King and Haskell counties they list AEP Texas North. Both are delivery-only utilities: homes on their lines buy power from a retail electric provider. Oncor's residential delivery revenue averaged 5.64¢ per kWh in 2025 and AEP Texas North's 5.86¢ per kWh, while retail providers' residential customers across Texas paid 17.23¢ per kWh, a past average over all plans and not an offer. Those are separate parts of a different bill and do not compare directly with Tri-County's bundled 15.07¢ per kWh¹; the Oncor page covers them. In Denton, Tarrant and Wise counties, Tri-County's records also sit beside CoServ, another member-owned co-op.

Outages, meters and rooftop solar

Members averaged 203 minutes without power in 2025 counting major events, fewer than the Texas average of 225 minutes, and 132 minutes with major event days excluded (130 minutes statewide). The average member saw 1.67 interruptions, against 1.71⁸ for Texas. These are IEEE 1366 measures; current outages are on the co-op's own outage map, which EIA does not track.

Every residential meter was an advanced meter in 2025 (100.0%). Members reported 1,907 net-metered rooftop solar systems with 17.4 megawatts of capacity: 16.2 per 1,000 residential customers, above the Texas figure of 10.8 and below the national 38.1⁹. How exported power is credited is set in the co-op's tariff; the net metering guide explains the general mechanics.

Business accounts

Tri-County counted 20,402 commercial accounts in 2025, which paid an average of 13.47¢ per kWh and were billed $637.75 a month. Its 1,271 industrial accounts are small by industrial standards, with an average bill of $127.71 a month, and they paid 16.66¢ per kWh, more per kWh than homes. Across all 139,530 accounts the co-op averaged 14.51¢ per kWh¹. The wider picture is on electricity in Texas.
