Gearless drive wind turbines to power Snowtown II

TrustPower will use gearless drive wind turbine technology from Siemens to construct South Australia’s largest wind farm at Snowtown.

The Snowtown II Wind Farm development will be capable of generating 270MW of renewable energy and powering approximately 180,000 South Australian homes.

Siemens CEO Jeff Connolly says he is pleased to have the opportunity to deliver lead-edge gearless drive technology to TrustPower.

“Our broad project responsibility for this critical piece of sustainable infrastructure is the result of our confidence in the South Australian construction environment and a further extension of our existing commitment to support the state’s development,” Mr Connolly said.

TrustPower, a listed New Zealand electricity company, awarded Siemens the contract to engineer, procure, construct and maintain a full turnkey solution for 90 wind turbines including the substation, switchgear and transformers to connect the wind farm into the grid.

TrustPower CEO Vince Hawksworth said Siemens’ capability as a leading global supplier of renewable energy and provider of full end-to-end solutions set them apart from other suppliers.

“The wind farm will be built with the most advanced renewable energy technology on the market. Of critical importance to us was the proven capability to build and connect wind farms to the grid and Siemens as a global supplier has achieved this in some of the most challenging environments in the world,” Mr Hawksworth said.

Siemens energy head David Pryke said Snowtown offers some of the most ideal wind conditions for the production of renewable energy.

“The wind technology chosen for the project is ideally suited to the Snowtown II site, featuring state-of-the-art gearless drive systems and highly efficient rotor blades allowing us to maximise the delivery of reliable renewable energy from this project,” Mr Pryke said.

With 26 per cent of South Australia’s electricity already generated by wind, the state has set a target of 33 per cent renewable energy by 2020.

Snowtown II is co-located with the existing Snowtown Wind Farm, which will more than triple the renewable energy generation of the region. Early preparations have commenced at the site with construction commencing this month to ensure the project is fully operational by the end of 2014.
