Due to open on the ASX on November 15, the IPO will offer about one billion shares to Australian and Singapore investors at $1.57 per share.
Singapore Power chairman Ng Kee Choe said his company would keep a 51% stake in SP AusNet.
The prospectus was launched on Friday with Singapore’s Monetary Authority and is scheduled for lodgement in Australia on Monday, November 14.
Ng said SP AusNet planned to invest further in electricity and gas transmission, as well as distribution growth opportunities in Australia and New Zealand.
SP Ausnet currently supplies gas to 504,000 customers in central and western Victoria, and electricity to 575,00 customers in the state's east.
Another Asian player is expected to put forward an even bigger IPO soon.
Hong Kong giant Cheung Kong Infrastructure (CKI) is said to be working with Deutsche Bank to list a A$1.8 billion trust that will hold half of the company's stakes in Victorian electricity distribution businesses Powercor and CitiPower, as well as half of its stake in South Australia's ETSA Utilities.
