AGL Energy Limited and Meridian Energy have entered binding contracts to construct a 420 MW wind farm at Macarthur in Victoria, Australia’s south west at a total capital cost of $1 billion. On completion in early 2013, the Macarthur Wind Farm will be the largest wind farm in the southern hemisphere, and one of the largest wind farms in the world. It will join AGL’s market leading suite of renewable energy generation assets.

The wind farm will comprise 140 Vestas V112-3.0 MW wind turbine generators and be constructed by a Vestas/Leighton Contractors consortium. The wind farm will be situated near Hamilton, 260 kilometres west of Melbourne, in the Shire of Moyne.

Scale Delivers Operating Cost Savings

AGL and Meridian will each fund 50% of the capital cost of constructing the wind farm. AGL will fund its share of the cost and the costs associated with the construction of a substation at Tarrone from its existing balance sheet capacity. AGL will have 100% ownership of the substation, which will enable the future development of a gas-fired power station.

AGL CEO and Managing Director Michael Fraser said: “The joint venture between AGL and Meridian combines the considerable experience and complementary skill sets of the largest renewable developers in Australia and New Zealand. I have great confidence the partnership will deliver significant benefits for both parties.”

AGL will acquire all of the wind farm’s energy output and renewable energy certificates.

Mr Fraser said: “This project is consistent with AGL’s renewable energy strategy and entrenches our position as the leading developer, owner and operator of renewable energy assets in Australia.

“As a result of utilising Vestas’s new 3.0 MW V112 turbines, we have been able to increase the capacity of the wind farm while reducing the number of towers from 174 to 140. This reduces the environmental footprint of the project and achieves substantial operating cost savings in excess of $30 million over the life of the wind farm.”

Operational as Market Demands More Renewable Energy

The recent enhancements to the 2020 Renewable Energy Target (RET) scheme will require around 9,500 MW of new renewable generation capacity to be built this decade.

The Macarthur Wind Farm is expected to be fully operational in 2013 at a time when it will be needed to meet the legislated demand for Renewable Energy Certificates under the RET scheme.

Good For The Environment

Once operational, the Macarthur Wind Farm will have the capacity to power more than 220,000 average Victorian homes and abate more than 1.7 million tonnes of greenhouse gases every year – the equivalent of taking more than 420,000 cars off the road each year.

The Premier, Mr Brumby, said: “This $1 billion project will help cut emissions, create new jobs and provide clean energy for Victorians. Attracting a renewable project of this scale to Victoria is yet another example of how Victoria is leading the way towards a clean energy future.”

Helping to Reach The Renewable Energy Target

Mr Fraser said that the renewable energy from the Macarthur Wind Farm would make a significant contribution to delivering the expanded RET. “The changes to the Renewable Energy Target scheme provided the investment certainty we needed to make Macarthur viable.”

The CEO of Meridian, Tim Lusk, said: “Wind generation has a substantial cost advantage over other grid scale renewable technologies that can be practically deployed in Australia.

We expect wind farms – and Macarthur in particular – to make a substantial contribution to Australian retailers meeting commitments under the Renewable Energy Target.”

Jobs, Economic Growth, and Community Benefits

AGL commissioned consultants Sinclair Knight Merz (SKM) to undertake an Economic Impact Assessment to calculate the benefits of AGL’s wind energy activities in the region and more broadly. In terms of employment, approximately 400 direct jobs will be generated at the peak of construction, as well as another 800 indirect jobs at the peak.

There will be ongoing employment for about 30 full time staff for 25 years following construction.

Direct construction expenditure in the region is estimated to be approximately $245 million between 2010 and 2013, with regional construction expected to add about 1.5% to the Gross Regional Product in 2013.

AGL and Meridian will jointly establish a Macarthur Wind Farm Community Fund which will operate for the life of the wind farm. Through the Community Fund, AGL and Meridian aim to bring positive benefits to the local community through grants that enable the broader community near the wind farm to participate in the benefits the project will bring.

Mr Fraser said: “One of the most important considerations in developing a wind farm is the need for a supportive local community. We believe there will be significant benefits for local people and businesses as the project gets underway. We are working closely with the Macarthur community to make sure we deliver these benefits in a way that protects the local environment.”

Committed to Renewable Energy

On completion, the Macarthur Wind Farm will augment AGL’s portfolio of renewable energy assets, which comprise about 30% of the company’s generation capacity. AGL is developing the Hallett group of wind farms in South Australia, with the Hallett 2 Wind Farm formally commissioned in April and Hallett 4 and 5 Wind Farms under construction and Hallett 3 in development. AGL formally opened the 140 MW Bogong Hydro Power Station last November, the final stage of the 391 MW Kiewa scheme. This has brought AGL’s hydro generation capacity to almost 800 MW.

Last month, AGL commenced construction of the 63 MW Oaklands Hill wind farm which is located 5km south of Glenthompson, also in western Victoria.

Meridian is New Zealand’s largest electricity generator and currently owns and operates nine hydro stations and three wind farms within New Zealand, and one wind farm in Australia:

  • Manapouri power station and eight hydro stations on the Waitaki River in the SouthIsland
  • Te Apiti wind farm near Palmerston North
  • White Hill wind farm in Southland.
  • West Wind farm in Wellington.
  • Mt Millar wind farm, Eyre Peninsula, South Australia

Internationally, Meridian has operations in Sydney Australia and San Francisco California. Meridian also retails electricity to around 188,000 customers throughout New Zealand, which includes households, farms, and businesses. It also provides electricity to New Zealand’s single largest electricity user, the Rio Tinto Alcan New Zealand Limited aluminium smelter in Bluff. Meridian invests strongly in renewable energy development and has over 1,500 megawatts of Australasian development opportunities in the development pipeline and has recently commenced construction on the Te Uku wind farm, in Hamilton, New Zealand.
