2019 will be a turning point for IFN?, page-27

Next financials will tell us that. The capital light and re-seller models are a good way of generating more direct revenue without creating more debt though so I give them points for creative strategies.
Power prices had an upswing in 2H CY18 as the old coal fired plant have become less reliable. Dropouts in coal fired generation have caused prices to spike upward.That may offset some of the LGC losses as well as the benefits of having battery storage come online in 2H FY19 (as per the Nov presentation). Heat waves across much of the southern continent and higher rates of AC use during hot northerly conditions will also help the revenue side I expect.
LGC prices may yet surge again as policy reviews and political changes have influenced this previously and have potential to do so again.

The rate of debt payment may slow as LGC prices drop away but it will still be paid down in a reasonable time frame IMHO. Time will tell.
