NSW: NSW wind farm defies high-profile critics

A wind farm that has taken more than 10 years to get up and running is powering customers who are determined to use green energy.

The Collector Wind Farm, backed by supply deals with ALDI supermarkets and energy utility Iberdrola, is the largest wind farm that RATCH-Australia has built in this country and will officially open on Tuesday.

The green energy replaces coal-fired sources in the electricity grid and is expected to save 320,000 tonnes of greenhouse gas emissions each year, or the equivalent of taking 120,000 combustion engine cars off the road.

The wind farm project was once slammed by local Liberal MP Angus Taylor, a former federal energy minister, as being part of an "economically unviable" industry that relied on massive subsidies.
