The Wind Power Plant Project Avignonet Lauragais (Haute-Garonne) was selected in the call for proposals Eole 2005 program (October 1999). The Building Permit was issued in April 2001. Work began in early 2002 ended in October. This facility was initially consisted of the installation of 10 wind turbines N50 on the locality "Brazil" common Avignonet Lauragais. Boralex (group "Waterfalls", Canada) in partnership with SERIS SA Operating Company Industrial Networks South, was the owner of the wind farm. The project implementation was entrusted Cegelec Sud Ouest, a leading electricity. Wind turbines are placed in a double line, taking advantage of the prevailing winds Northwest and Southeast. The selected site is located north of the town, on an agricultural area and away from main roads. Land retained their use after the project. The plant was expanded in February 2008 by the construction of two new Enercon E70 in North East range. Finally opened in July 2011 and connected to the network in November of the same year, a 4.5 MW photovoltaic park was installed between the two rows of wind turbines. Becoming the first "green" energy mix in France Park.

Characteristics of the wind farm :

Type Machine Nordex N50 Enercon E70
Power 800 kW 2000 kW
Diameter 50 m 70 m
Height of platforms 50 m 75 m
Total Power 8000 kW 4000 kW
Developer Poweo EED
Owner Operator Boralex Boralex

Characteristics of the photovoltaic park :

Number of modules 20320
Type Silicium polycristallin
Height floor 2,20 m
Terreste installed surface 13 Ha
Photovoltaic surface active 3 Ha
Rated Power 4500 kW
Owner-Operator Boralex

The power plant was connected to the source by ERDF processing station located in Avignonet RD813 board. The coupling of these two "green" energy allows the power supply to 5,000 households (excluding heating) and avoid the emission of approximately 4,000 tons of CO2.

And Men...
(extracts dailynews Dépêche du Midi)

Twelve wind turbines are located north of Avignonnet, on the ridge of a place called "Brazil", what should we think! Some people decry, others approve. As each innovation, they suffer the fires of criticism. In the 19th century, the Railways were burning wheat fields, even burn sheep wool ...
Highways have suffered assaults rule sounds, gas, etc., not to mention the TGV, and it will soon be time for airlines ... Human beings react when approved, forever, especially on what is new. Those who deplore the turbines are initially shocked by the "visual pollution" of the environment, and they know by writing, leaflets attacking elected ... Others say that these peaceful and huge white birds enliven the landscape when their wings turn. Much citizens abstain or do not care, as for the elections. Some say that the wind does not belong to anyone, it is better to use than building thermal or nuclear power plants. In conclusion, many of them would prefer but also, and not at home ...

But Avignonet, do you really thought of everything ...
