Origin Energy stands to increase gross earnings by about $650 million in 2025-26 if its huge Eraring coal power generator remains open, according to Morgan Stanley estimates, in findings that may play into the terms of a deal expected to be struck with the NSW government to extend its life.
The estimate, by Morgan Stanley energy analyst Rob Koh, came as NSW Treasurer Daniel Mookhey warned Origin against “gaming the system” in its negotiations with the state government on an extension of the 2880-megawatt generator past Origin’s targeted closure date of August 2025.

Mr Koh’s estimate is a theoretical one that assumes coal prices at the current cap of $125 a tonne, and wholesale prices around current levels for the financial 2026 year. But in reality there is considerable uncertainty on what those prices will actually be then.
The NSW government’s confirmation on Wednesday that the price cap on thermal coal will end on June 30, 2024 – after which royalty rates on coal will be increased – underlines that uncertainty. Top-quality Newcastle thermal coal prices are currently almost double the cap, at about $US160 ($250.50) per tonne.
