Wind Turbine Payback in Red River County, TX

Wind turbine payback in Red River County

No. The turbine wears out before it pays for itself.

At 30 m, the height a home turbine tower usually reaches, the wind in Red River County, TX averages 5.04 m/s (11.3 mph). A 10 kW turbine there would make about 12,805 kWh a year, worth $2,053 at TX's 16.03¢/kWh. Against an installed cost of about $100,000, that is a payback of 49 years, and the turbine is built to last about 20.

What to do in Red River County

A home turbine is not worth buying for savings in Red River County unless your spot is far windier than the county average, 7.6 m/s at the hub against 5.04 m/s here. Per kW, solar panels would make about 1,340 kWh a year here against the turbine's 1,281, so get a solar quote first.

What would have to change

Against the rest of TX

Red River County is the 1,436th windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in TX is Dallam County at 6.82 m/s, payback 24 years.

Month by month in Red River County

March is the strongest month here, at 5.83 m/s and about 1,566 kWh. August is the weakest, 3.98 m/s and 550 kWh, so the best month makes 2.8 times the worst. November to March brings in 51% of the year's output in Red River County.

What a taller tower would buy

Measured at 10 m the wind in Red River County averages 3.76 m/s; at 50 m it is 5.78 m/s. That gives a shear exponent of 0.267, typical of ordinary open country. Going from 20 m to 50 m takes output from 9,493 to 18,079 kWh a year, 90% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

Sun versus wind in Red River County

Red River County gets 4.59 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,340 kWh a year; one kW of the turbine above makes 1,281. Kilowatt for kilowatt, panels make 1.0 times as much here as the turbine. Panel output assumes an 80% system performance ratio. Wind or solar runs the same comparison for every county.

How this is worked out

Wind is NASA's Power climate record, the 2001-2025 average at 10 m and 50 m for the county's centre, carried to 30 m with this county's own measured wind shear and spread into hours with a Rayleigh distribution. The turbine is a generic 10 kW, 7 m rotor machine with 10% losses. Cost is $10,000 per kW installed with no tax credit, because the federal one ended in 2025. One county-centre number cannot see your hilltop or your tree line, so treat it as the starting point for a site survey, not a substitute. The full method and its weak spots are in how the numbers are made.
