High production peaks in the winter months

The greatest amount of energy is generated between October and April, with the hig-

The 8,000 meter square windfarm has wind turbines that are 55 meters tall, the same height as a 23-foor building. The blades spin a maximum of 30 ti-mes per minute, at a speed of 4 m/s to 25 m/s. After reaching the speed of 25 m/s, they stop to avoid spinning at a greater speed.

hest production peaks recorded in the win-ter months. In the summer, there are days when a lot of energy is generated although sometimes the machines have refrigeration problems because of the high temperatures of the gondola which can reach more than 50°C. When this happens, the machines come to a halt until the temperature goes down. Energy from each windmill is trans-

ferred through an underground cable sys-tem. The generators are hooked on series, joined together into different groups. The fber optic power cables are placed in 130 cm-deep ditches, and transport the elec-tricity and information to the substation. The voltage is transformed here to about 220,000 V and redistributed through the power grid by means of high-voltage cables and towers.
