Suzlon Group has announced the launch of its newest wind turbine – the S111 - 2.1 MW machine designed for low wind speed sites.
Suzlon announces new low-wind turbine with up to 29 percent increased output

Featuring a rotor diameter of 111 meters, and a swept area of more than 9,500 square meters, the S111 is the latest generation of Suzlon’s 2.1 MW fleet, and one of the highest-yielding IEC Class III wind turbines of any comparable class machine.

“We are extremely pleased to introduce the S111 wind turbine," said Suzlon Chairman Tulsi Tanti during a visit to Atlanta, Georgia in the US. "This new turbine builds on our extensive experience operating over 2,500 units of our S88, S95 and S97 2.1 MW turbine platforms around the world.

“With the industry increasingly looking to lower wind speed sites, the S111 represents a major step forward in our strategy to create products that deliver ever increasing output from lower wind speeds, delivering solutions that precisely fit our customers’ needs. We believe the S111 will be a market defining product,” Tanti said.

Giving the North American perspective, Duncan Koerbel, Suzlon Wind Energy Corporation’s interim CEO and Global Head of OMS, said, “In today’s ultra-competitive North American PPA market, our customers need a higher efficiency machine that can generate more megawatts at the lowest possible cost per kWh. We believe S111 meets those needs.

“We will offer the S111 with tower heights of 95 and 120 meters, and combined with our all new third generation rotor, the S111 will deliver a 20 to 29 per cent increase in annual energy production over our S97 design in a 90 meter configuration,” Koerbel said.

The S111 program will have its first prototype operational in late 2013 and serial production will begin in 2014.
