The production of wind energy presents some unusual features which are mainly associated with its uncontrollable nature. This factor makes it necessary to have a backup power system of sufficient capacity constantly available. Such backup power must be provided by other sources of energy.
This feature means that the forecasting, tracking and control functions related to this type of generation must be as accurate as possible. This is achieved through tele-metering of wind farm output and it allows the electricity system to be operated appropriately with regard to safety and in an economic fashion - similar to power stations operating under the ordinary regime.
These real time wind power production charts are prepared from data on the mainland electricity system obtained by Red Eléctrica´s control system.
