Jeffreys Bay Wind Farm | South Africa Jeffreys Bay Wind Farm assists in meeting the ever-increasing demand for electricity in South Africa. Arising from the South African Government’s Renewable Energy Independent Power Producers Procurement Programme (REIPPP), the wind farm supplies the Eskom gridline with 460 000 MWh per year. Jeffreys Bay Wind Farm is one of the first and largest wind farms in South Africa. Each year the wind farm generates sufficient electrical energy to meet the needs of 100,000 average South African households. The Jeffreys Bay Wind Farm benefits the local community in many ways. Through enterprise development, the creation of procurement and employment opportunities and the development of a local community trust, the wind farm is invested in the communities in its vicinity. There are many environmental benefits of wind energy. Reduced carbon emissions, water saving and zero air and water pollution make wind energy a clean, renewable cost effective energy source.

View More Community Benefits Socio-Economic & Enterprise Development Community Trust Procurement & Employment View More FAQs Why is wind a feasible renewable energy option in South Africa? Large parts of South Africa’s coastal land, as well as various areas inland, have an economically viable source of wind energy. Furthermore, the scale and maturity of the global wind industry have made it a cost-competitive energy option, compared not just to other renewable technologies but also many fuel-based technologies. Also with significant local content, these technologies can also raise the employment intensity of the electricity generation sector. How many wind turbines are sited at Jeffreys Bay Wind Farm? The project comprises of 60 wind turbines. How big are the wind turbines? The height and weight statistics of the wind turbines are: a hub height of 80 meters a blade length of 49,5 meters a rotor diameter of 101 metres the rotor weighs 60 tones the nacelle weighs 82 tones the tubular steel tower weighs 162 tones How do wind turbines operate? Wind turbines are sophisticated machines with computer controls. A typical operating sequence is as follows: when the wind speed reaches the cut-in speed of the turbine (usually around 4 metres per second), the turbine blades will spin up to operating speed, usually around 14 to 29 rpm (varies by turbine model), and start generating electricity as the wind speed increases, the generator output increases when the wind speed increases to the rated wind speed (usually around 12-13 metres per second), the generator will output its nameplate-rated capacity (i.e. a 750-kW turbine would now output 750 kW) as the wind speed continues to increase, the generator output will remain at the rated capacity (i.e. 750 kW) until the wind reaches the cut-out speed (usually around 25 metres per second) at this wind speed, the turbine will deploy its tip-brakes and then apply its disk brake, stopping the blades in a few revolutions it will then rotate itself 90 degrees out of the wind and park itself if the wind speed drops to a level below the cut-out speed for a sufficient length of time, the turbine will point itself back into the wind, release the brake, and resume power production. What happens when the wind doesn’t blow? By its very nature, wind varies and does not blow consistently all the time. This is why, where the wind turbines are sited is so important; erecting them in an area with prevailing winds ensures that the turbines can generate energy and provide energy to the grid about 90% of the time. The wind turbine only cuts in (starts operating) when wind speed reaches approximately 13km/h. Are wind turbines noisy? Modern wind turbines are not considered noisy; the mechanical (gearbox/ generator) noise and vibration is almost undetectable with the main sound being the aerodynamic swish of the blades passing the turbine tower. Animals and livestock ignore wind turbines, and continue to graze as they did before wind turbines were installed. Do wind turbines kill birds? In answer to the concern that wind turbines kill birds, studies show that birds are seldom bothered by wind turbines and in fact, the number of birds killed by wind turbines is negligible compared to the number that die as a result of other human activities. Studies from the western part of Denmark, show that birds – by day and night – tend to change their flight route some 100 – 200 metres before the turbine and pass above the turbine at a safe distance. Bird studies form an integral part of the Environment Impact study and any adverse affects will be highlighted during this stage of the development. See Denmark Bird Study here. What happens if turbine throws a blade or a tower collapses, maybe on neighbour’s property or a power line? When designing the site layout, our team ensured that turbines are located with ample clearance from the border of the property, main roads and power lines so that, in the highly unlikely event that a tower collapses, it will not traverse the border of the property. Can wind farms affect airport and military radars? Jeffreys Bay Wind Farm doesn’t fall within the ‘radar buffer distance’ and therefore can’t affect any airport or military radars. What about neighbourhood/community acceptance? The Environmental Impact Assessment included a comprehensive stakeholder consultation process as a prerequisi... Similar Website
