Wind Turbine Payback in Meeker County, MN
Wind turbine payback in Meeker 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 Meeker County, MN averages 6.25 m/s (14 mph). A 10 kW turbine there would make about 21,558 kWh a year, worth $3,544 at MN's 16.44¢/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 Meeker County
A home turbine is not worth buying for savings in Meeker County unless your spot is far windier than the county average, 7.5 m/s at the hub against 6.25 m/s here. Per kW, solar panels would make about 1,133 kWh a year here against the turbine's 2,156, so get a solar quote first.
What would have to change
- Power would have to cost 23¢/kWh, 1.4 times what MN pays now.
- Or the average wind at the hub would have to be 7.5 m/s instead of 6.25. A taller tower or an exposed ridge can add some of that; a rooftop never will.
Against the rest of MN
Meeker County is the 528th windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in MN is Lincoln County at 6.68 m/s, payback 25 years.
Month by month in Meeker County
April is the strongest month here, at 6.90 m/s and about 2,164 kWh. July is the weakest, 5.22 m/s and 1,192 kWh, so the best month makes 1.8 times the worst. November to March brings in 45% of the year's output in Meeker County.
| Month | Wind at 30 m | Output | Worth |
|---|---|---|---|
| January | 6.52 m/s | 1,998 kWh | $328 |

What a taller tower would buy
Measured at 10 m the wind in Meeker County averages 4.92 m/s; at 50 m it is 6.98 m/s. That gives a shear exponent of 0.217, typical of ordinary open country. Going from 20 m to 50 m takes output from 17,649 to 26,900 kWh a year, 52% 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 | 5.72 m/s | 17,649 kWh | 35 years |
| 30 m | 6.25 m/s | 21,540 kWh | 28 years |
| 40 m | 6.65 m/s | 24,509 kWh | 25 years |
| 50 m | 6.98 m/s | 26,900 kWh | 23 years |

Sun versus wind in Meeker County
Meeker County gets 3.88 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,133 kWh a year; one kW of the turbine above makes 2,156. This is one of the rare places where a kilowatt of turbine out-produces a kilowatt of panels, by 1.9 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.
