Wind Turbine Payback in Doddridge County, WV
Wind turbine payback in Doddridge 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 Doddridge County, WV averages 3.29 m/s (7.4 mph). A 10 kW turbine there would make about 3,541 kWh a year, worth $552 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 Doddridge County
A home turbine is not worth buying for savings in Doddridge County unless your spot is far windier than the county average, 7.7 m/s at the hub against 3.29 m/s here. Per kW, solar panels would make about 1,124 kWh a year here against the turbine's 354, so get a solar quote first.
What would have to change
- Power would have to cost 141¢/kWh, 9.1 times what WV pays now.
- Or the average wind at the hub would have to be 7.7 m/s instead of 3.29. A taller tower or an exposed ridge can add some of that; a rooftop never will.
Against the rest of WV
Doddridge County is the 2,761st 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 Doddridge County
January is the strongest month here, at 3.97 m/s and about 545 kWh. August is the weakest, 2.47 m/s and 110 kWh, so the best month makes 5.0 times the worst. November to March brings in 61% of the year's output in Doddridge County.
| Month | Wind at 30 m | Output | Worth |
|---|---|---|---|
| January | 3.97 m/s | 545 kWh | $85 |
| February | 4.05 m/s | 523 kWh | $81 |
| March | 3.85 m/s | 496 kWh | $77 |

What a taller tower would buy
Measured at 10 m the wind in Doddridge County averages 1.99 m/s; at 50 m it is 4.15 m/s. That gives a shear exponent of 0.457, typical of rough, sheltered ground: trees or buildings slow the low wind a lot. Going from 20 m to 50 m takes output from 1,871 to 7,354 kWh a year, 293% 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 | 2.73 m/s | 1,871 kWh | over 100 years |
| 30 m | 3.29 m/s | 3,527 kWh | over 100 years |
| 40 m | 3.75 m/s | 5,376 kWh | over 100 years |
| 50 m | 4.15 m/s | 7,354 kWh | 87 years |

Sun versus wind in Doddridge County
Doddridge County gets 3.85 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,124 kWh a year; one kW of the turbine above makes 354. Kilowatt for kilowatt, panels make 3.2 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.
