"Over the last year, we've obviously seen an absolute explosion in our pipeline," IBISWorld research analyst Andrew Ledovskikh says.
His research has found Australia currently has about 2.3 gigawatts (GW) worth of power capacity in 79 data centres.
That's enough to power about 1.5 million homes, depending how you work the numbers.

"That comes at a $4.1 billion opportunity a year," she said.
