If you replace the 2,1 Megawatt per station of my post below by 9,5 Megawatt x 75% (9,5 being the figure on page 6 of your document), you have a savings of 7,1 megawatt, so my ROI below becomes 21% x 7,1/2,1 = 71%.
And if you take only 50% for power saving, the ROI becomes :
21% x 9,5 x 50%/2,1 = 47%
This is consistent with your figures.

To how much does the energy savings amount to, apart from the flow effect ?
The energy savings of 75% brings the power from 2,8 Megawatt to 0,7 Megawatt per station.
Ballpark cost of 0.05 $/KilowattHour in the US so 50$ per MegawattHour.
So a savings of 2,1 Megawatt per station leads to :
2,1 x 50$ x 24h/day x 365day/year = 919,800 $ /year per station. At 4,3 M$ per AOT pack, the ROI is "only" 21%.
