My understanding is that they are not obligated to inform the market as its confidential and you can see the margin as a composite margin. In one announcement they inferred that the gross margin had not changed and at that time they had about a 30% GP.

If you do a search on utility style electricity pricing versus what you pay as a retailer you can work out a margin relatively easily.

Certainly from my calculations there is more than enough in it but you need to research it.
