So, bear with me.
Aus used a tad under 900Pj of electricity last year.
Sxy 350Pj represents let's say 1/3 of one year.

The value of traded electricity on the national electricity market is about 10-11 billion aus.

I'm sure if sxy supply was converted to electricity there would be energy loss and costs.
Idk what that would be let's say half.

So that leaves 1/6 Australian annual electricity needs or about 1.8 billion aud at current market prices.
