Roaring Brook Wind Farm

The Details

The Roaring Brook Wind Farm was constructed in Martinsburg, Lewis County, New York.  The 79.7MW wind farm is comprised of 20 wind turbines. The wind turbines consisted of 5 Gamesa G114 2.6MW turbines and 15 Siemens Gamesa SG145 4.5MW turbines, the first of their configuration installed in North America. This was a comprehensive wind power construction project that leveraged expertise and experience at the heart of The Wesson Group's history; full EPC Contract, project requirements included design, permitting, roadways, foundations, above- and below-ground medium-voltage collection and high-voltage substation construction. TWG returned to Lewis County, where they constructed their first wind farm, for this project. This project was recognized by North American Clean Energy and featured in the November 2022 Magazine Issue.

Scope of Work

The Challenge

This was a full EPC project located in an extremely environmentally sensitive area. Preserving the NYSDEC and USACE wetlands on this project was paramount. The project also had a large 6 miles portion of overhead collection through many land locked areas within sensitive wetlands. Another major challenge was working with the new Siemens Gamesa G145 Turbine model. This was the first installation in North America of this specific configuration of this turbine, with multiple revisions to the specifications as the turbines were constructed.

The Result

Coordination with stakeholders was key to the success of this project. The project was constructed on schedule, on budget, with quality, safety, and environmental stewardship. There were no contraventions of water quality documentation on this project. The challenges relative to the new tower model and OEM multiple specification revisions were overcome and the towers were successfully mechanically completed and commissioned. A transparent team environment geared at solving problems as they arose, was fostered by The Wesson Group and was paramount to the success of the project.
