In December 2018, Tempo Engineering engaged MAD3 Engineering (formerly McDowall Affleck) to undertake the detailed design of the civil works for the 80 hectares site located on Leitchville Kerang Road, approximately 8km south of Cohuna, Victoria 3568, which had been identified for the development of a 34 MW solar farm by Enel Green Power. Cohuna Solar Farm boasts approximately 87,000 bi-faced panels that harness sunlight on both sides to achieve improved efficiency in energy generation. With 34 MW of installed capacity, the plant generates 77 GWh per year and decreases CO2 emissions by approximately 70,200 tonnes over 12 months.
Scope Of Work
Civil works design including:
- Hydrology/Hydraulics study
- PV panel layout optimisation
- Drainage design
- Road and inverter pad design
Project Challenges
- Extremely tight time and budget constraints
- Demanding Development Approval conditions
- Global EGP specifications do not match Australian Standard practice
How We Managed This
MAD3 Engineering and its Italian partner Studio Techné assisted Tempo Engineering in clearing Development Approval conditions and liaised with Enel Green Power to obtain relaxation of their global specifications to better reflect Australian Standard practice.
Value Engineering
MAD3 Engineering and Studio Techné worked with Tempo Engineering and Enel Green Power to deviate from Enel Green Power global specifications to optimise the design without compromising the performance requirements. Such approach was possible due to the trusted long-term relationship with Enel Green Power and allowed Tempo Engineering to meet their budget expectations.
