Classic Fleet

Over the last two decades, Suzlon has built a range of turbines that can generate 600KW to 2100KW of power. These turbines continue to generate power across the world, supported by Suzlon’s operations and maintenance services. With the introduction of new, high-yield next generation wind turbines, Suzlon has phased out the manufacturing of its older WTG (wind turbine generator) models - S97, S88, S82, S66, and S52.

Suzlon, however, continues to support, operate and maintain all its installed wind turbines.

S97

S97

The Suzlon S97 - 2.1MW 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 which 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. View the story behind the award

The S97 series has been phased-out since 2018. During the three years of its successful installations, more than 1200 turbines of S97 were installed with a cumulative capacity of more than 2500 MW.

Why was S97 the preferred choice?

  • An award-winning innovation by Suzlon
  • Increased height and stability
  • Reduced cost, simpler logistics and ease of construction
  • Design that enables higher generation
  • Made low wind sites that were previously unusable, viable

S88

S88

The S88-2.1MW was designed for a medium wind speed regime. Inducted into the Suzlon fleet in 2004, the S88-2.1MW 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 2720 turbines were installed with a combined generation capacity of 5712MW. This product was one of the best and most successful to have come out of the Suzlon stable.

The S – 82

S82

The S82-1.5MW was designed for generating optimal power output even at sites with a modest wind speed regime.

Inducted in 2006, the S82-1.5MW 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 2023 turbines installed with a combined generation capacity of 3034.5MW.

S66

S66

The S66-1.25MW was designed for generating the optimal power output even at sites with a modest wind speed regime.

S66-1.25MW 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, 2939 turbines of the S62 along with similar turbines like the S64 and S70 were installed cumulatively generating 3673.75MW of energy.

S52

S52

The S- 52 600KW 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 457.20MW were installed.
