Not sure to be honest. I know SA sends a lot to Vic but not sure if Vic sends a lot to NSW.

Also new SA-NSW interconnector project should provide more opportunity to IFN. FCAS and customer market increased opportunity I would think.

For IFN it means there is a chance to sell FCAS direct to NSW as well as SA and Vic.

I think it will also give SA a chance to sell more renewable electrons into NSW and undercut coal plant generation more often.
