A further irony is that because an increase in wind power capacity is seen on the grid as an increase in demand fluctuation it requires dedication of other grid capacity to cover it Rather than reducing other sources wind power requires building more conventional capacity particularly natural gas fired plants which it then forces to operate less efficiently
Get PriceWind speed has an important effect on pumping capacity Below certain speeds the mill can t get going Above 25 35 mph depending on the model the windmill s overspeed controls limit the output by turning furling the direct face of the wheel out of the main wind direction This design feature protects the windmill mechanism but it also limits the pumping rate no matter how fast

Get Price· The wind can disappear for days even weeks far beyond not only the capacity of any storage system but the ability for the wind power to ever fill that capacity and simultaneously provide the power expected by the grid The environmental footprint of a wind system is apparently huge I have seen estimates that almost 300 000 acres would normally be required to site enough turbines to
Get PriceAnother way of stating the annual energy output from a wind turbine is to look at the capacity factor for the turbine in its particular location By capacity factor we mean its actual annual energy output divided by the theoretical maximum output if the machine were running at its rated maximum power during all of the 8766 hours of the year Example If a 600 kW turbine produces million
