Siemens Gamesa Renewable Energy has launched its next-generation wind turbine, the SG 3.4-145, in India. The turbine is specifically designed and optimised for wind conditions in the country and aims to deliver the lowest possible levellised cost of energy (LCoE) with high reliability. The new product is an extension of the Siemens Gamesa 3.X platform and will be manufactured at its facilities in India starting early 2021. The SG 3.4-145 has been upgraded with the 145 metre rotor of the Siemens Gamesa 4.X platform owing to its modularity, thus increasing the swept area by 41 per cent and annual energy production by 48 per cent compared to the previous SG 2.2-122. This rotor is already under production in India.
The SG 3.4-145 stands 127.5 metre tall, with a blade-tip height of 200 metres, which helps it maximise the wind potential at every site. Furthermore, the turbine is designed to adapt to the country’s extreme and varying weather conditions, supported by an advanced monitoring and cooling system that ensures efficient thermal conditioning and performance at high-temperature sites.
The prototype of the SG 3.4-145 wind turbine was commissioned successfully at the Alaiz wind farm in Spain. The 145 metre rotor diameter uses 71 metre long blades and can operate up to 3.6 MW with a flexible rating strategy. The product has been designed to comply with the global IECRE Standards and meets the Indian CEA 2019 requirements as well.
