 When used in conjunction with a variable resistive load, a higher wind penetration is possible, permitting the substantial second to second variability to be controlled with the resistor, reducing the need to spill excess wind through throttling of the turbines.A short-term peak output of 400 kW can be supplied.As a result, there has been a substantial reduction in the use of diesel fuel, however the full diesel capacity must be maintained, including the need to maintain spinning reserve for system security.
