It is RES's largest ever solar project, which once fully operational will have 450,000 solar panels and will generate electricity for 80,000 homes in the east coast state.

The construction is expected to begin later this year and will create more than 230 full-time local jobs during construction, RES said.

The project will help avoid over 157,000 tonnes of carbon each year and had won approval from the state government in 2019.

"The optimised portfolio of Avonlie project will enable Iberdrola to provide its growing customer base with long-term electricity contracts that are at once reliable, affordable and clean," Ross Rolfe, chief executive of Iberdrola Australia, said.
