Mumblin Wind Farm

About the Wind Farm

The Mumblin Wind Farm will consist of eight wind turbine generators with a combined capacity of approximately 54 megawatts (MW), and will generate enough power for approximately 35,000 homes.

The location of the proposed Mumblin Wind Farm is shown on the map below. This site has been chosen for the following reasons:

It receives undistributed wind flow with strong, consistent wind speeds.
It is in close proximity to the electricity grid;
There are large setbacks to houses;

There will be minimal effects on flora and fauna;
It offers easy access for construction.

Revised Wind Farm Layout

The wind farm layout has recently been revised and now consists of eight wind turbine generators. The key changes made to the previous are as follows;

One wind turbine has been removed from the wind turbine layout;
One wind turbine has been moved by less than 200 m;

Three wind turbines have been moved by less than 50 m.

To partially offset the reduction in the overall capacity of the wind farm a more powerful wind turbine model has been adopted, and as a result the capacity of the wind farm remains at approximately 54 MW. The overall height of this turbine model is 5 m greater than the model we previously proposed, meaning an overall height of 252 m instead of 247 m.

The new wind farm layout is shown in the below map.

Environmental Benefits

The wind farm will have significant environmental benefits as it will replace energy that would otherwise be generated by burning fossil fuels.

Modelled energy output per year (MWh)

~190,000 MWh

Greenhouse gas emissions reduction (Tonnes CO₂)

~190,000 t

Equivalent number of households that can be powered by green energy annually

~35,000

Equivalent number of cars whose emissions will be offset.

~ 43,000 pa

Equivalent number of trees which would provide the same emissions reduction.

~280,000

Connection to the Electricity Grid

The proposed location of connection to the electricity grid remains unchanged, being an existing powerline that passes along Cobden – Warrnambool Rd. There will be no new overhead powerlines on the wind farm site as all electrical cables internal to the wind farm site will be located underground. There will also be no new powerlines required off the site.

Meteorological Monitoring

There is now one meteorological masts located on the wind farm site. The mast carries monitoring equipment that measures, records and transmits wind and weather data. This essential data informs the design of the wind turbines to ensure they achieve maximum efficiency while minimising wear and tear.
