Wind Power

Wind power technology uses a device known as a ‘turbine’ to convert the energy of the blowing wind into mechanical energy which is then converted into electricity.  This technology is now the fastest-growing form of renewable energy in the world.

Sundance’s five-state service area is blessed with some exceptionally strong wind sites. If you are fortunate enough to have a site with good resources, wind power may be the right renewable energy choice for you.  Depending on your energy objectives, and your site’s wind resources, Sundance can provide a wind power system that connects to your electric utility (‘grid-tied’) to reduce or offset your energy bills, or we can provide a system that offers you complete independence from your utility (‘off-grid’).

How Wind Power Works
In reality, wind energy is simply solar energy in motion.  The sun’s energy heats different parts of the earth at different rates (i.e. different types of land surfaces, urban versus rural areas, bodies of water), and those rates change around the clock and through the seasons.  This in turn, causes portions of the atmosphere to warm differently.  Hot air rises, and cooler air is drawn in to replace it.  The result is wind.  The faster the wind, the more energy it has which may be captured.To measure the wind potential of a site, Sundance takes measurements using an anemometer and consults wind resource maps published by NOAANREL, and other meteorological research organizations.  Due to the physics of wind, accurate measurements are critical – a wind blowing twice the speed has eight times the energy.

Some of the energy of the wind can be captured and converted into electricity using a wind turbine.  The blades of the turbine rotate in proportion to the speed of the wind, and in turn, rotate the shaft of a generator.  Some generators produce direct current (‘DC’), while others produce alternating current (AC) directly.

Using data collected during the site assessment, Sundance will determine the best type and size of wind turbine and mounting tower for the wind conditions of your site.

Power from the wind turbine is routed to the ‘balance of system’ components that condition the produced electricity for connection to your utility or for use on your site.  If your system is ‘off-grid’ or grid-tied with back-up, additional components including batteries and charge controllers will also be designed into your system.  Sundance uses its own collaborative 5-Step Design Process to partner with you to ensure that your energy needs, objectives, site conditions and budget are considered.

For each kilowatt-hour of electricity your wind system produces, it also creates a ‘Renewable Energy Credit’ (also known as a ‘REC’ or a ‘greentag’) which has significant value in the marketplace.  In addition to selling the electricity itself to your local utility, you can sell the electricity’s renewable energy attribute.  Sundance will help you obtain the highest price from the sale of your RECs.  To learn more, contact Sundance.

Advantages of Wind Power
  • Wind can be used in both Off-Grid and Grid-Connected Systems.
  • Wind is the perfect compliment to an Off-Grid solar system because especially in the winter, windy conditions and cloudy weather occur simultaneously.
  • If you have a strong wind source, wind can be one of the most cost effective renewable energy technologies.
  • Wind has the capacity to produce power continuously all day and night in periods of windy weather
