Largest Wind Farm In Southern Hemisphere Opens Down Under

The 420 megawatt Macarthur wind farm was opened in the state of Victoria on Friday. It is the largest wind farm in the southern hemisphere and its 3 megawatt Vestas turbines are the largest in Australia. The Mcarthur Wind Farm is actually the first project to use Vestas’ V112-3.0 MW wind turbines. The project’s expected operating capacity is 35% and its cost was almost exactly one billion dollars.

One billion dollars may sound like a lot of money, probably because it is, but that doesn’t mean it’s not a good deal. The wind farm has an operating life of 25 years and if a 5% discount rate is used for the cost of money, it will generate electricity at about 6 cents a kilowatt-hour. While this is slightly higher than the average price of electricity generated from coal in Australia, it does have the very large advantage of being non-fatal on both the personal and planetary scales. It’s also cheaper than electricity from new coal plants and is a major reason why Australia is extremely unlikely to ever build any new coal capacity.
