Wind Turbine Payback in Lincoln County, NE

Wind turbine payback in Lincoln 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 Lincoln County, NE averages 6.5 m/s (14.5 mph). A 10 kW turbine there would make about 23,407 kWh a year, worth $3,024 at NE's 12.92¢/kWh. Against an installed cost of about $100,000, that is a payback of 33 years, and the turbine is built to last about 20.

What to do in Lincoln County

A home turbine is not worth buying for savings in Lincoln County unless your spot is far windier than the county average, 8.8 m/s at the hub against 6.5 m/s here. Per kW, solar panels would make about 1,317 kWh a year here against the turbine's 2,341, so get a solar quote first.

What would have to change

Against the rest of NE

Lincoln County is the 208th 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 Lincoln County

April is the strongest month here, at 7.24 m/s and about 2,364 kWh. August is the weakest, 5.57 m/s and 1,403 kWh, so the best month makes 1.7 times the worst. November to March brings in 45% of the year's output in Lincoln County.

What a taller tower would buy

Measured at 10 m the wind in Lincoln County averages 5.14 m/s; at 50 m it is 7.25 m/s. That gives a shear exponent of 0.214, typical of ordinary open country. Going from 20 m to 50 m takes output from 19,401 to 28,811 kWh a year, 49% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

2 of the 6 closest counties are windier at turbine height; the windiest, Logan County, averages 6.66 m/s.

Sun versus wind in Lincoln County

Lincoln County gets 4.51 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,317 kWh a year; one kW of the turbine above makes 2,341. This is one of the rare places where a kilowatt of turbine out-produces a kilowatt of panels, by 1.8 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.
