Panchabuta had mentioned in December that Suzlon Energy is banking on its new turbines, which can generate power at low wind speeds, to gain an early-mover advantage in the segment.
The company, India’s biggest and the world’s third-largest wind turbine maker, will bring out the prototype of its class-III turbine by February 2011, Robin Banerjee, group chief financial officer, had then said.
As Panchabuta had then opined, high PLF- high potential wind sites are more or less exhausted in India and as Suzlon has observed most of the current installations are happening in Class-II site and there are a number of Class -III sites that have identified but not utilized yet and this should help Suzlon move in that area early on giving it a distinct advantage like the one it enjoys now in some of the high potential wind sites in Tamil Nadu and Gujarat. Panchabuta understands that Greenko group that is developing the 65MW-Ratnagiri Wind Power Projects Ltd- with a technology partnership with GE is planning to use GE’s latest XLE class turbines, which are specifically designed for low wind regimes in India and Class-III sites.
Speaking at the launch of the new S95 and S97 turbines, Mr. Tulsi Tanti, chairman and managing director of Suzlon said that the new S9X suite was designed with the end customers in mind and that they were ideally suited for the emerging markets. He further added, that the turbines were well suited for medium and low wind regime sites and that the rotor diameters are bigger. He also added that the new turbines would incorporate better grid compliance.
He mentioned the biggest challenge the technology team faced in design of this turbine was the increase in cost that would have to be incurred due to design for a low regime wind site and how that had to be balanced with the customer interest, requirements and feedback in mind. The turbine also achieves better standards of reliability and technology.
The S95 would be available in the second quarter of this financial year and the S97 in the fourth quarter. There are a couple of orders include one order for a single turbine from a Ahmedabad based company and another 100Mw order from the Simran Wind farm which is a project of Techno Electric, Kolkota that is currently under implementation, subject to testing and certification.
The company further added that the series was built on the existing S88 platform that has been proven and tested and that this will have a higher availability than 97% that was achieved in that platform.
The blades are also state of the art and have been designed in-house by the Suzlon technical team along with LM Wind. The company adds tha the reliability and availability has been tested for Indian conditions.
