Something important to be aware of, LGC forward prices have moved significantly over the last 6 months. This is from a recent online event run by BRC-A on renewable energy and LGCs. I know Genex only sells LGCs from Jemalong but it also significantly improves the economics of Kidston wind (and other renewable investments).
Say Jemalong sells 100,000 LGCs a year and the price improves $20, that’s an extra $2 mil a year in revenue. And the price for all certs (CY22-30 until the end of the RET) has increased by around 20 dollars in the last year.
