Wind Turbine Payback in Tioga County, NY

Wind turbine payback in Tioga 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 Tioga County, NY averages 3.63 m/s (8.1 mph). A 10 kW turbine there would make about 4,862 kWh a year, worth $1,423 at NY's 29.26¢/kWh. Against an installed cost of about $100,000, that is a payback of 70 years, and the turbine is built to last about 20.

What to do in Tioga County

A home turbine is not worth buying for savings in Tioga County unless your spot is far windier than the county average, 5.6 m/s at the hub against 3.63 m/s here. Per kW, solar panels would make about 1,057 kWh a year here against the turbine's 486, so get a solar quote first.

What would have to change

Against the rest of NY

Tioga County is the 2,354th windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in NY is Niagara County at 6.87 m/s, payback 13 years.

Month by month in Tioga County

January is the strongest month here, at 4.42 m/s and about 752 kWh. August is the weakest, 2.83 m/s and 179 kWh, so the best month makes 4.2 times the worst. November to March brings in 61% of the year's output in Tioga County.

What a taller tower would buy

Measured at 10 m the wind in Tioga County averages 2.25 m/s; at 50 m it is 4.54 m/s. That gives a shear exponent of 0.436, typical of rough, sheltered ground: trees or buildings slow the low wind a lot. Going from 20 m to 50 m takes output from 2,735 to 9,580 kWh a year, 250% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

5 of the 6 closest counties are windier at turbine height; the windiest, Tompkins County, averages 3.88 m/s.

Sun versus wind in Tioga County

Tioga County gets 3.62 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,057 kWh a year; one kW of the turbine above makes 486. Kilowatt for kilowatt, panels make 2.2 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.
