WES30 Power curve There are two ways to generate a wind-turbine Power curve: •    Calculate how much energy the air passing through the swept area of the turbine can generate, or •    Measure the amount of electrical energy being produced by the system. The second way to generate a Power curve is the more reliable one. The Power curve for the WES30 has been measured by the ( ECN ) the Dutch Energy Research Centre. WES dealers use the results of these measurements and have access to the detailed Power curve data. WES dealers can make an accurate calculation of the amount of energy that can be produced in your specific environment. Use the WES30 calculator for a first production estimation for your site.   WES30 calculator    Wind speed [m/s]  Power [kW] 2,7 Cut-in wind speed  3  1,5  4  4,4  5  14,9  6  29,3  7  56,3  8  77,2  9  116  10  145  11  179  12  222  13 - 25  250         Wind speed [m/s]   Annual energy  [MWh]   4   136   5   285   6   464   7   656   8   841   9   1.015   10   1.107   more than 10   1.107 ++
