Wind Turbine Payback in Hale County, TX

Wind turbine payback in Hale 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 Hale County, TX averages 6.37 m/s (14.2 mph). A 10 kW turbine there would make about 22,447 kWh a year, worth $3,598 at TX's 16.03¢/kWh. Against an installed cost of about $100,000, that is a payback of 28 years, and the turbine is built to last about 20.

What to do in Hale County

A home turbine is not worth buying for savings in Hale County unless your spot is far windier than the county average, 7.6 m/s at the hub against 6.37 m/s here. Per kW, solar panels would make about 1,545 kWh a year here against the turbine's 2,245, so get a solar quote first.

What would have to change

Against the rest of TX

Hale County is the 380th 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 Hale County

April is the strongest month here, at 7.35 m/s and about 2,425 kWh. August is the weakest, 5.37 m/s and 1,284 kWh, so the best month makes 1.9 times the worst. November to March brings in 45% of the year's output in Hale County.

What a taller tower would buy

Measured at 10 m the wind in Hale County averages 4.97 m/s; at 50 m it is 7.15 m/s. That gives a shear exponent of 0.226, typical of ordinary open country. Going from 20 m to 50 m takes output from 18,319 to 28,109 kWh a year, 53% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

3 of the 6 closest counties are windier at turbine height; the windiest, Swisher County, averages 6.48 m/s.

Sun versus wind in Hale County

Hale County gets 5.29 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,545 kWh a year; one kW of the turbine above makes 2,245. This is one of the rare places where a kilowatt of turbine out-produces a kilowatt of panels, by 1.5 times. 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.
