An Indian wind firm has launched a turbine set to be a “market defining” product for low wind sites. Suzlon, the world's fifth largest wind turbine manufacturer, has announced the launch of its latest wind turbine, the S111 2.1 MW machine, designed for low wind speed sites around the world, including the US.

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

Announcing the new product at WINDPOWER 2012 in Atlanta and speaking at the launch, Tulsi Tanti, Suzlon Group chairman, said: “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.”

Duncan Koerbel, Suzlon Wind Energy Corporation’s interim CEO and global head of OMS, said the turbine will particularly benefit the US. He 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 120m, 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 90m configuration.”

John O’Halloran, president of technology for Suzlon Energy, said: “The S111 builds on our considerable experience in the 2 MW space and combines it with our leading edge capabilities in blade design and testing to create a highly efficient turbine.

“The design builds on extensive feedback from customers and leverages the strengths of our existing designs, enabling wide commonality with our current offerings and passing savings in operations to our customers. This is our fourth new turbine that the technology team has designed, developed and launched in the last three years. We continue to progressively optimise our equipment and are leveraging our New Product Development process to introduce improved turbines with shortened development cycles.”

The S111 program will have its first prototype operational in late 2013 and serial production will begin in 2014. With the launch of the new S111 - 2.1 MW Suzlon is officially making the turbine available for sale.
