Suzlon Energy Limited products

S97 Wind Turbine Generator is a part of our latest 2.1 MW range of products, the S97 Wind Turbine Generator (WTG) has been designed to make low wind sites viable.

Suzlon’s new S120 wind turbine generator, built on the highly successful 2.1 MW platform is set to improve the ROI for customers and a new benchmark in the wind industry. Wider rotor diameter of 120 metres with swept area of 11,225 sq. meters. Suitable for low wind sites IEC Class S. Next-generation controls with state-of-the-art software. All new individual pitch control mechanism.

The S88-2.1 MW was designed for a medium wind speed regime. Inducted into the Suzlon fleet in 2004, the S88-2.1 MW was designed to withstand extreme conditions and operate effectively with low maintenance costs. The S88 was phased out in 2015 after 11 years of successful operations, during which time a total of 2,738 turbines were installed with a combined generation capacity of 5,748 MW. This product was one of the best and most successful products of Suzlon.

The S82-1.5MW was designed for generating optimal power output even at sites with a modest wind speed regime. Inducted in 2006, the S82-1.5 MW is equipped with an asynchronous generator with high slip; it can operate within a limited speed range. In conjunction with the pitch system, it is possible to achieve an optimal energy yield within a wide wind range, with comparably low loads. Till its phase-out in 2015, there were 2,022 turbines installed with a combined generation capacity of 3,033 MW.

The S66-1.25 MW was designed for generating the optimal power output even at sites with a modest wind speed regime. S66-1.25 MW is equipped with a dual-speed, dual-rating asynchronous generator; it can operate within a limited speed range. In conjunction with the pitch system, it is possible to achieve an optimal energy yield within a wide wind range, with comparably low loads. Between 2002 and its eventual phase-out in 2016, 2,940 turbines of the S62 along with similar turbines like the S64 and S70 were installed cumulatively generating 3,675 MW of energy.

The S-52 600 KW is similar to the S–66 1.25, but with lower energy generation capacities. Between 2006 and 2014, 762 turbines with a total installed capacity of 457 MW were installed.

Suzlon boasts of a wide range within its 2.1 MW suite of products with varying rotor blade and tower heights suitable for all wind regimes. The S111 wind turbine has an impressive 111 rotor diameter, which can extract maximum power from available wind. S111 offers various hub height (90m, 120m, 140m) and construction (Steel Tubular, Hybrid Lattice, Hybrid Concrete) options depending upon site conditions to optimally harness wind energy for maximum generation.  The S111-140m (140 meter hub height) prototype was set up in August 2017 in Gujarat, has achieved 43% plant load factor (PLF). It received its Type Certification in June, 2017. The installed serial fleet confirms the high plant load factor and availability above 97%.

The Suzlon S97-2.1 MW series is an award-winning wind turbine generator range which was specially designed to make low wind speed sites profitable. It was available in two variants:  S97-90m - All steel tubular tower that reaches a height of 90m. S97-120m - All steel tower that combines the lattice and tubular structure with a unique transition piece that reaches a height of 120m. This innovative design of S97-120m won the prestigious Golden Peacock award 2016 in the ‘eco-innovation’ category.
