Isladar, the saving of 15% is for the energy part of the costs. C1 is $900, but only 30% is energy. IE. 15% of $300 which is $45.

Sector, not the same.You seem to be agreeing that 12c EXU equates to 50 RMS as per EvFletcher.  Adding in one place and subtracting in another doesn't always add up.

By way of explanation. A little puzzle:

3 men go to Las Vegas and check into a hotel late at night. The night manager charges $300. Each man forks out $100. 

The next morning the day manager realise they've been overcharged by $50. He gives the bellboy $50 to return to the guests. The bellboy recognizes that the $50 can't be readily divided by 3, so returns $30 and pockets the $20. So each guest now gets back $10, thus they've paid $90 each. 3*90 =$270. The bellboy has $20. So $270 + 20 = 290. Where did the other ten dollars go.
