On March 16th, Peter Brett from Eco Power took us on a guided tour of his family’s wind farm. Eco Power rent the land on which the turbines are built from local farmers. Houses must be at least 500m away from these turbines.
These 32 wind turbines were built in 2004 and are remote controlled. They produce enough energy to power between 450 and 600 homes daily. Their blades can turn 360 degrees to suit the wind direction. The blades flatten out when they are stopped.
The main parts of the wind turbine are the tower, the hub and the fibreglass blades. It takes less than 1 day to assemble a wind turbine, the foundations and Renee bolts are put in place over 3 days and then they must wait for a calm day. The 2 towers are placed one on top of the other by a crane, then the macell box, the blades and finally the hub. Enercon and Vestes are the two companies who have built the wind turbine son this wind farm. Peter and his team maintain the Vestes wind turbines but Enercon monitor their own.
Electricity is produced when the mechanical turning force of the blades is changed to electricity in generator. This energy is then changed to a high voltage, low amp state so it can be transported to Eco Power’s substation, the power station in Castle ar to its final destination, the national grid. Currently, wind energy provides for 30% of Ireland’s energy needs.
Every part of the wind turbine is recyclable except the blades, which range from 48m to 52m in diameter on this farm. Some newer turbines are 2 and a half times the size of these. The strongest winds on this farm come from the West but the day we were there, the winds were coming from a Northwest direction. Eco Power’s grid connection allows for 35 turbines only so the next 3 will be erected in the coming year.
The children had a wonderful day and we thank Peter for taking time out to show us around!
