Further comment.

Available generator capacity is constrained by thermal coal plant
sighted within coal reserves that have now been exhausted, now moving
fuel from further away, and hanging on waiting for the plant
maintenance costs to exceed profit after transport costs.  Just
business and logistics.

None of which seems to be visible in the public political discourse
which instead fixates on policy responses.


And risk of load-shedding this summer estimated by the market operator
at up to 43% for most vulnerable state.


Load-shedding typically begins with the large industrial customers
like aluminium production.
