Wind Turbine Payback in Nicholas County, WV

Wind turbine payback in Nicholas 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 Nicholas County, WV averages 3.56 m/s (8 mph). A 10 kW turbine there would make about 4,570 kWh a year, worth $712 at WV's 15.58¢/kWh. Against an installed cost of about $100,000, that is a payback of over 100 years, and the turbine is built to last about 20.

What to do in Nicholas County

A home turbine is not worth buying for savings in Nicholas County unless your spot is far windier than the county average, 7.7 m/s at the hub against 3.56 m/s here. Per kW, solar panels would make about 1,136 kWh a year here against the turbine's 457, so get a solar quote first.

What would have to change

Against the rest of WV

Nicholas County is the 2,451st windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in WV is Preston County at 3.73 m/s, payback over 100 years.

Month by month in Nicholas County

January is the strongest month here, at 4.35 m/s and about 720 kWh. August is the weakest, 2.60 m/s and 133 kWh, so the best month makes 5.4 times the worst. November to March brings in 62% of the year's output in Nicholas County.

What a taller tower would buy

Measured at 10 m the wind in Nicholas County averages 2.22 m/s; at 50 m it is 4.43 m/s. That gives a shear exponent of 0.429, typical of rough, sheltered ground: trees or buildings slow the low wind a lot. Going from 20 m to 50 m takes output from 2,572 to 8,924 kWh a year, 247% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

1 of the 6 closest counties is windier at turbine height; the windiest, Greenbrier County, averages 3.57 m/s.

Sun versus wind in Nicholas County

Nicholas County gets 3.89 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,136 kWh a year; one kW of the turbine above makes 457. Kilowatt for kilowatt, panels make 2.5 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.
