Vortexis will work with your company to build a site specific "wind available" analysis using such tools as AWS True Power

(click map of Florida). With data in hand, Vortexis engineers along with decision makers at your company can determine the ideal customized solution.

## ENERGYPRODUCTION     ## PRODUCTIONFORMULA   According to the AWEA Small Wind Turbine Performance and Safety Standard, the Rated Annual Energy of a wind turbine is the calculated total energy that would be produced during a 1-year period with an average wind speed of 5 meters/second (m/s, or 11.2 mph). The following formula illustrates factors that are important to the performance of a wind turbine. Notice that the wind speed (V) has an exponent of 3 applied to it. This means that even a small increase in wind speed results in a large increase in power. That is why a wind turbine should be mounted on a tower at least 10 meters above the highest elevation nearby - thus maximizing the productivity of any wind turbine by giving it access to higher wind speeds.

How do wind turbines work? Here are some wind turbine facts: Nano and micro wind energy systems can be connected to the electricity distribution system and are called grid-connected systems. A grid-connected hybrid energy system can reduce your consumption of utility-supplied electricity for lighting, appliances, and electric heat. If the turbine cannot deliver the amount of energy you need, the utility makes up the difference. When the wind system produces more electricity than the business requires, the excess is sent or sold to the utility.

Power = Cp 1/2 ρ A V³

Where:

• P = Power output, watts
• Cp = Maximum power coefficient, ranging from 0.25 to 0.45, dimension less (theoretical maximum = 0.59)
• ρ = Air density, kg/m³
• A = Rotor swept area, m² or
• π D² / 4 (D is the rotor diameter in m, π = 3.1416)
• V = Wind speed, mps
