India’s Suzlon Group, the world’s fifth largest wind turbine maker, has announced a next generation turbine for the country. The 1.5MW range focuses on harnessing Class III low-wind sites.

The new turbine is specifically designed to deliver high efficiency and cost-effective power generation even at low wind speeds, therefore increasing the size of the market and making wind power projects even more financially competitive than they are today.

The S8X is designed specifically for the Indian market where the majority of potential lies in medium-to-low wind sites. This turbine is designed with advanced rotors, with diameters of 86.5 and 89m, and a tower height of 90m, which will bring improvements in energy yields of between 15 to 20 per cent over the current S82 – 1.5 MW offering in low wind conditions.

Tulsi Tanti, Suzlon Group chairman, said: “We are very pleased to bring this cutting edge offering to the market. As the Indian wind market continues to grow at over 40 percent per year, we believe the S8X will be a game changer in the high-growth 1.5 MW segment –delivering higher reliability, uptime, energy production and ultimately greatly improved returns on investment to customers over its lifecycle.”

Additionally, the S8X is designed specifically to operate in high temperatures, and to meet the current and future grid requirements in India. This turbine is an evolution of the proven S82 – 1.5MW platform, with approximately 2,400MW in installations consistently delivering 97 per cent plus availability.

The new design also incorporates several key features from the S9X suite of turbines, helping to achieve higher reliability, improved power output, higher safety and improved lightening protection. Like the S9X, the new turbine offers an improved pitch and yaw system, hub assembly, main frame and other key components, ensuring easier maintenance, greater reliability and higher uptime.

John O’Halloran, Suzlon Energy, technology president, said: “This marks an extremely important step forward in our product strategy. The S8X builds on our extensive operating experience with our highly successful S82 – 1.5MW fleet in some of the most challenging environments in the world. The development program drew extensively on feedback from our key customer groups – primarily PSUs and IPPs in India – to create a product that meets their current and future needs, and provides consistently improving returns on investment.

“The S8X features advanced blade designs and highly efficient control systems to optimise loads and performance – delivering higher reliability, significantly improved energy output and ultimately, increased financial performance for our customers.

These turbines will be built to the latest guidelines issued by certification agencies, with even more advanced and stringent testing standards than previous guidelines,” he added.

Developments in wind energy turbines in India will be a focus in the agenda of BigSwitch Offshore Wind. The international event, which Renewable Energy Technology (RET) is sponsoring, is taking place in Glasgow on 27h and 28th June. It aims to advance technological developments across global offshore wind by encouraging the European renewable energy industry to work with key delegations from the world’s biggest emerging markets, including China and India, as well as the US.
