Wind Harvest expects to install Wind Harvester® 4.S turbines on the Coke Dock Peninsula in St. Croix, U.S. Virgin Islands. The energy generated will power the grid of the local oil refinery that controls the land. Designed to endure harsh marine environments and Category 5 hurricanes, these vertical axis wind turbines (VAWTs) are uniquely suited for island deployment. This project will help open other wind properties on the islands to development with Wind Harvesters.

St. Croix, a Caribbean island with strong trade winds and open terrain, is an ideal site for Wind Harvester technology.

• This first project should qualify for 50% Investment Tax Credits and 100% bonus depreciation, which significantly reduces the amount of capital needed.
• The islands and site have good wind resources that continue to blow after sunset.
• Large traditional wind turbines have not been installed for many reasons, including impacts on views, the threat of Category 5 hurricanes, and transportation of large components.
• Energy prices are high on the island, and solar has its limitations and requires a lot of storage.
• St. Croix is exempt from US tariffs.

This project marks a unique collaboration between Wind Harvest and a St. Croix oil refinery—powering the facility with clean energy while reducing pollution and reliance on imported propane. The project will create local jobs, use existing facilities for assembly and installation, and deliver long-term energy cost savings.

Engineered specifically for tempestuous environments, the Wind Harvester 4.S features corrosion-resistant components and a reinforced base designed to withstand winds up to 80 m/s (180 mph). Its compact, modular design simplifies installation and long-term maintenance, making it an ideal fit for coastal and island settings.

Environmental stewardship is central to Wind Harvest’s mission. Vertical axis wind turbines with their 3d shape and slower moving blades are naturally safer for birds and bats. Wind Harvest has hired Geographic Consulting to conduct bird observation studies, which began in the spring of 2025. If birds on the peninsula are unable to see and avoid Wind Harvester turbines in operation, the company will use advanced bird detection systems to slow down or pause turbine rotation when protected species approach, preventing harm to local and migratory birds.

The Least Tern is territorially endangered in the Caribbean. These birds do not nest on the Coke Dock Peninsula, so are not expected to be impacted by this project.

St. Croix will serve as the launchpad for the Wind Harvester 4.S, showcasing its durability, efficiency, and ease of deployment in marine environments. Once operational, this project will signal to governments, businesses, property owners, and energy consumers across the Caribbean and beyond that resilient wind energy is not only possible—but practical and affordable.
