Wind Turbine Payback in Hitchcock County, NE
Wind turbine payback in Hitchcock 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 Hitchcock County, NE averages 6.24 m/s (14 mph). A 10 kW turbine there would make about 21,484 kWh a year, worth $2,776 at NE's 12.92¢/kWh. Against an installed cost of about $100,000, that is a payback of 36 years, and the turbine is built to last about 20.
What to do in Hitchcock County
A home turbine is not worth buying for savings in Hitchcock County unless your spot is far windier than the county average, 8.8 m/s at the hub against 6.24 m/s here. Per kW, solar panels would make about 1,364 kWh a year here against the turbine's 2,148, so get a solar quote first.
What would have to change
- Power would have to cost 23¢/kWh, 1.8 times what NE pays now.
- Or the average wind at the hub would have to be 8.8 m/s instead of 6.24. A taller tower or an exposed ridge can add some of that; a rooftop never will.
Against the rest of NE
Hitchcock County is the 541st windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in NE is Cherry County at 6.83 m/s, payback 30 years.
Month by month in Hitchcock County
April is the strongest month here, at 6.94 m/s and about 2,188 kWh. August is the weakest, 5.55 m/s and 1,391 kWh, so the best month makes 1.6 times the worst. November to March brings in 43% of the year's output in Hitchcock County.

What a taller tower would buy
Measured at 10 m the wind in Hitchcock County averages 4.9 m/s; at 50 m it is 6.99 m/s. That gives a shear exponent of 0.221, typical of ordinary open country. Going from 20 m to 50 m takes output from 17,555 to 26,971 kWh a year, 54% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.
| Hub height | Average wind | Output | Payback |
|---|---|---|---|
| 20 m | 5.71 m/s | 17,555 kWh | 44 years |
| 30 m | 6.24 m/s | 21,512 kWh | 36 years |
| 40 m | 6.65 m/s | 24,536 kWh | 32 years |
| 50 m | 6.99 m/s | 26,971 kWh | 29 years |

Sun versus wind in Hitchcock County
Hitchcock County gets 4.67 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,364 kWh a year; one kW of the turbine above makes 2,148. This is one of the rare places where a kilowatt of turbine out-produces a kilowatt of panels, by 1.6 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.
