AGL Energy has entered into agreements for the construction of a 132MW Hallett-4 wind farm at North Brown Hill in South Australia.

According to the company, the Hallett-4 wind farm will consist of 63 2.1MW S88 V3 turbines to be purchased from Suzlon Energy Australia.

The Hallett-4 site is located 220km north of Adelaide and immediately north of the Hallett-1 wind farm that was commissioned in June 2008.

The long-term average wind speed at Hallett-4 is estimated to be greater than 8.5m², similar to the wind conditions prevailing at Hallett-1 and at the Hallett-2 wind farm currently under construction.

The company has entered into a turnkey engineering, procurement and construction contract and supply agreement with Suzlon. AGL said that it has further options with Suzlon to construct either the Hallett-3 or Oaklands Hill wind farms at average turbine prices similar to those for Hallett-4. If AGL commits to the construction of both Hallett-3 and Oaklands Hill wind farms, a further volume discount will be available from Suzlon.

The company has a diverse power generation portfolio including base, peaking and intermediate generation plants, spread across traditional thermal generation as well as renewable sources including hydro, wind, landfill gas and biomass.
