Hello
The ‘Cost’ value for Tank Energy Cost Results, I can not understand how is calculated. I guessed It has to be the same value as ‘Energy Cost’ for related Pumps, but I was wrong.
How does WaterGEMS calculate Cost for Tanks? And what is correlation between Energy Use Cost of Pumps and Cost of related Tanks?

Sim,
Here is a link to a support solution that explains how the Cost ($) is figured.

So when Cost (for a tank)=14$ it means that HGL (End)<HGL(Begining) and 14$ is required to put the level of End equal to level of Begining. is it correct?
Yes, it means that, based on the pumps' cost per unit volume, it is estimated to cost $14 to fill the tank back to the original level. This is added to the overall cost for the energy cost analysis in order to give a complete view.

Hello Jesse
Another question has remained for me:
How can calculate 'Stored Energy' (for tanks)?
1- First way is subtracting level of water at the end of simulation from level at the beginning and then convert it to Energy after considering Pump Efficiency. (By E=mgh formula)
2- Another way to calculate 'Stored Energy' is using Pump itself and calculating how much energy must be consume to pump 'Volume Change' into the tank. Pump Efficiency is considered.
Please assess and opine on these two ways.
Thanx
The second option appears to the the way it is calculated.
