Correction to ROI due to energy savings :
If the 2,1 Megawatt savings is per pump and not per station as per Earth1's recent post, the ROI of 21% below becomes 21% x 3 = 63%
If you take the amortization and operating costs out, the ROI would be between 50% and 60%, only taking into account the energy savings and not the flow effect.

An easy to remember figure : 1 Million $ of energy savings per pump per year !

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%.
