Going Where Existing Wind Technology Cannot Go

 High-wind sites are blocked for one or more of the following reasons:

  1. There may be objections from neighboring landowners or communities.
  2. There may be infrastructure costs that make a project prohibitive.
  3. There may be height restrictions set by the need for air corridors, civilian, or military operations
  4. Wildlife restrictions may present problems.
  5. Access to the site for shipping HAWT turbine parts/blades may be impossible.

WHI Turbine Systems may offer a solution for your site.  Utilizing 18m tall turbines in arrays that are modular and relatively low-tech, this complementary technology can go where the 130m tall horizontal axis wind turbines (HAWT)  cannot go.

Capacity Factor Enhancement

For existing wind farms, significant costs are sunk in infrastructure, substations and transmission investment.  Wind is an intermittent resource, and the average capacity factor of sites around the world is about 25%.  If we produce more power on the site by building an understory of WHI Turbine Systems between the large turbines, we can significantly raise the capacity factor of a significant percentage of today’s wind farms.

Double Production For Many New Wind Farms

This may seem like an outrageous claim, however an understanding of the paradigm of Power Density begins with an assessment of the Optimal Power Production of the site. It is basic:  the MORE CLOSELY SPACED the turbines in a WHI VAWT System, the MORE EFFICIENT.  This is the physics of VAWT technology, and its promise.  Higher land utilization is key.  For those who are open to big new pieces of the wind puzzle, WHI Turbine Systems open gates to significant new resources of renewable energy.

Transition Aging Wind Farms to Higher Production

Premium wind sites built out in the late 80s and early 90s are coming to the end of their useful life.  WHI Turbine Systems can support developers in managing the transition through understory installation of WHI 70kW VAWTS, and re-evaluating the Optimal Power Potential of the site.

Capitalizing on complementary technologies, HAWT and WHI VAWT Turbine Systems can yield significantly higher production and capacity factor on many of these high-wind, close-to-load sites.
