Wind Turbine Payback in Oswego County, NY

Wind turbine payback in Oswego 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 Oswego County, NY averages 4.74 m/s (10.6 mph). A 10 kW turbine there would make about 10,826 kWh a year, worth $3,168 at NY's 29.26¢/kWh. Against an installed cost of about $100,000, that is a payback of 32 years, and the turbine is built to last about 20.

What to do in Oswego County

A home turbine is not worth buying for savings in Oswego County unless your spot is far windier than the county average, 5.6 m/s at the hub against 4.74 m/s here. Per kW, solar panels would make about 1,048 kWh a year here against the turbine's 1,083, so get a solar quote first.

What would have to change

Against the rest of NY

Oswego County is the 1,592nd 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 Oswego County

January is the strongest month here, at 6.22 m/s and about 1,815 kWh. July is the weakest, 3.51 m/s and 371 kWh, so the best month makes 4.9 times the worst. November to March brings in 65% of the year's output in Oswego County.

What a taller tower would buy

Measured at 10 m the wind in Oswego County averages 3.54 m/s; at 50 m it is 5.43 m/s. That gives a shear exponent of 0.266, typical of ordinary open country. Going from 20 m to 50 m takes output from 7,928 to 15,534 kWh a year, 96% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

Sun versus wind in Oswego County

Oswego County gets 3.59 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,048 kWh a year; one kW of the turbine above makes 1,083. This is one of the rare places where a kilowatt of turbine out-produces a kilowatt of panels, by 1.0 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.
