The University of NSW has signed an agreement to become fully solar powered.

UNSW has signed a 15-year agreement with solar company Maoneng Australia and energy company Origin for a solar corporate power purchase agreement (PPA).

The agreement will see solar energy from Maoneng’s Sunraysia solar farm provide 100 per cent of the campus’ energy.

Sunraysia, which will be constructed near Balranald in NSW, will be the largest solar farm in Australia, generating at least 530,000-megawatt hours of electricity annually.
