Musk responded with a fixed cost of $250,000 per kilowatt hour for systems that produce over 100 megawatt hours of energy, adding that Tesla offered fixed prices for all customers.
"Holy s#%t", he tweeted, then appealed to Musk directly: "Lyndon & @elonmusk - how serious are you about this bet?".
The offer prompted Cannon-Brookes, co-founder of Australian software developer Atlassian Corp, to ask Musk on Twitter whether the offer was serious.
"It is just making sure we can get the rules set in a way that maximises battery storage, being able to offer that solution and with the backing of some fantastic people like Elon Musk and Mike Cannon-Brookes, I think we can make it happen", she said.
It seems the process has already been started as Sarah Hanson-Young, Senator of South Australia and Jay Weatherill, Premier of the state reached out to Elon Musk. Zen Energy, chaired by economist Ross Garnaut, last month said its proposal for a $100 million large-scale solar plant with battery storage could solve most of South Australia's electricity problems if rules were changed to make it viable.
A spokesman for Mr Weatherill declined to comment further about the specifics and how much funding the state government may be prepared to commit to advance such a proposal.

Early on, Tesla worked in private with companies to sort out pricing depending on the size of the contract.
Tesla recently completed an installation of an 80MWh grid-scale battery farm in southern California within just 90 days, which cost $100m.
As the federal government grapples with talk of an energy crisis, two tech billionaires appear to be getting a ground-breaking deal done on Twitter.
Apparently, Elon Musk is 100 percent behind Rive on this, which is what Cannon-Brookes challenged in the tweet above. The SpaceX emperor and Tesla overlord has been keeping an eye on the power blackouts that keep hitting South Australia, and he's made a decision to step in and lend a hand.
