Number Three Wind Farm

The Details

The Number Three Wind Farm was constructed in Lowville, Lewis County, New York. The 103.9MW wind farm comprised 27 wind turbines. The wind turbines consisted of 5 GE 2.3MW turbines with 116-meter rotors with 80-meter towers and 22 VESTAS 4.2MW V150-4.2 turbines with 150-meter rotors atop 105-meter towers. The WTG design finalization included two wind turbine foundation designs. This project was recognized by North American Clean Energy and featured in the November 2023 Magazine Issue.

Scope of Work

• 54,000 linear feet of access roads and 27 wind turbine foundations

• 175,000 tons of subbase placed for the access roads, crane pads, laydown yard, and radii

• 1,250 tons of rebar procured and installed

• 16,000 cubic yards concrete procured and installed

• Sitewide erosion control best management Practices

• Daily on-site safety management

• WTG erection

The Challenge

The site had challenges with the component deliveries, crane walks and civil construction due to the ground conditions with the record rainfall weather events. In addition, numerous turbines were sited within a flood plain. There was also a design-build development need with a quick turnaround to meet schedule, for the point of interconnect access road bridge within New York State Department of Transportation easement.

The Result

The Wesson Group worked alongside the owner to come up with the best overall solution for the benefit of the project. The Wesson Group teamed with wwner/engineers/financiers to develop excavation and dewatering plans to complete the foundation excavations in a safe/efficient manner. The Wesson Group reduced costs and schedule impacts to the owner by proposing a stone strong abutment/pre-engineered bridge deck in lieu of a costly cast-in-place bridge that was initially included in the preliminary designs.
