Ausenco was hired by Enercon to install six E-70 E4 2.3MW wind turbines at the 14MW Grasmere Wind Farm in Albany, Western Australia.
The wind farm now produces around 44 GWh of electricity each year and, together with the Albany Wind Farm will produce 104 GWh to meet 80% of Albany’s electricity needs with clean inexhaustible renewable energy.
The Grasmere wind farm is located at a site 11 km south-west of Albany adjacent to the existing Albany wind farm and is, in effect, an extension of the existing Albany wind farm. The chosen site is an excellent one for wind farming, having a good wind resource, available land and a community already comfortable with, and supportive of, the technology.
The new turbines were placed on the coast using the same pattern and spacing as the existing wind farm and were built to the same high environmental and social standards.
The electrical cabling was buried underground and operates at 22,000 Volts (or 22kV) and runs between the wind turbines and back to the Albany substation.
Grasmere results in the saving of 43,500 tonnes of greenhouse gases per year from electricity production, equivalent to taking 10,000 cars off the road. It is being developed, owned and operated by Verve Energy.
The wind turbines have been commissioned in stages with the installation and erection component completed in November 2011.
This wind farm will also feed electricity into the Western Australian South West Interconnect System (SWIS) supplying renewable electricity free of carbon emissions.
