Mr Musk, who runs electric vehicle giant Tesla, which recently merged with his solar energy outfit SolarCity, was responding to Atlassian boss Mike Cannon-Brookes who tweeted "Holy s#%t" in reference to the plans.
In a follow-up tweet, Musk offered Cannon-Brookes a pricing quote for the project: $250 per kilowatt-hour of energy for 100-megawatt-hour systems, according to Reuters, which amounts to a total of $25 million for the batteries.
In a Twitter conversation Thursday with Australian tech billionaire Mike Cannon-Brookes, Musk bet he could get the systems up and running within 100 days, although Cannon-Brookes might want Musk to go slightly over his target.

Battery storage would help prevent further blackouts by increasing the peak amount of energy available to the grid.

It also said that the company could do the same in the neighboring state of Victoria, which lingers under the risk of frequent blackouts after the recent closure of the Hazelwood coal-fired power station.
