A consortium involving Mike Cannon-Brookes' Grok Ventures and Quinbrook Infrastructure Partners is understood to be the winner of the bidding for Sun Cable, one of the world's biggest solar projects.
An overseas partner is also a member of the consortium that won the bidding, AAP understands.
The deal could be announced as soon as Friday or Monday, a source told AAP on Thursday, speaking on condition of anonymity.
The massive project to export solar power from the Northern Territory to Singapore via a sub-sea cable was placed in administration in January after disagreements between its billionaire backers, Mr Cannon-Brookes and Fortescue Metals' Andrew Forrest.
Mr Forrest has said he became disillusioned when the project ballooned to more than $35 billion.
He had submitted a bid with a plan to develop the Australian portion of the project while scrapping the submarine cable, while Mr Cannon-Brookes was committed to its original vision.
FTI Consulting was soliciting binding bids from interested parties, which were due this week.
Quinbrook Infrastructure Partners is an ESG (environmental, social and governance)-focused investment manager with projects in Australia, the US and the UK.
The Australian first reported that Mr Cannon-Brookes had won the bidding.
