Murra Warra II Wind Farm located 25km North of  Horsham, VIC comprises 38 wind turbines with a capacity of 209MW constructed adjacent to the 61 turbines of the first stage of Murra Warra Wind Farm. It has provided over 400 full time equivalent jobs during its two year construction period, and will provide ongoing employment opportunities during its operational lifetime.

Murra Warra Wind Farm Stage II will produce enough clean energy annually to power 90,000 homes, reducing carbon emissions by approximately 500,000 tonnes each year.

Zenviron was subcontracted to carry out the Design and Construct sub-contract for GE International for the Balance of Plant (BOP) Civil and Electrical works. The project includes Tie-in works to the existing substation on site which was constructed to accommodate Stage 2. GE supplied and installed a rotating stabiliser as part of their contract to provide inertia into the Grid at this part of the network. 

Zenviron’s scope included 26kms of access track which required lime stabilisation for subgrade improvement, crane hardstands and the wind turbine foundations with each foundation having in excess of 780m3 of structural concrete and more than 95 tonnes of reinforcing bar.

The medium voltage collector system was made up of a combination of 10km of 33kV overhead line and 32km of underground cable. A purpose built operation and maintenance building was constructed for GE on the site.

The direct economic stimulus provided by the Murra Warra Wind Farm has been in the order of $10M to the local and regional economy through spend on accommodation, retail items and services. It is expected that the stage 2 turbines will be commissioned and fully operational in Q2 2022.
