Engie, who own the Hazelwood site (with some partners) are on the hook to "rehabilitate" it when they are done burning coal.
And they are definitely done burning coal, because it's no longer cost effective to maintain the old equipment and it's definitely too risky to build new burners.
So here's what they plan for the site long term: https://www.hazelwoodrehabilitation.com.au/
And in the short term, they are still a power company, so why not plonk their new batteries there, the site they own and which already has big connections to the power networks.
This is disgusting, even if you don't care about the cuddly wildlife, it's clear this plant is spewing a toxic amount of waste into the surrounds.
This is the wrong headline for this story.
