Scenario Energy Cost Manager
The Scenario Energy Cost Manager is used to set up energy cost calculations. To calculate energy costs, the following information must be supplied:
To access the Scenario Energy Cost manager, click the Analysis > Energy Costs command, or click the Energy Costs button 
.
The left pane consists of a tree view that contains the name of the base scenario when it is first opened. Click the scenario icon to activate controls in the right side of the dialog that will allow you to specify the elements that will be used in the energy cost calculations.
Use the Compute button 
to calculate the energy costs based on the information set in the Energy Pricing Manager (accessed by using the Energy Pricing 
button for the currently selected scenario; select the scenario to use with the Scenario pull-down menu).
Before performing energy cost calculations, it is necessary to have run an extended period simulation for the scenario of interest.
If price of energy is not entered, the scenario energy cost calculations will calculate energy use but now cost.
After energy costs have been computed, the tree view will also contain icons for Pump/Turbine Usage, Storage, and Peak Demand details. Click on an icon to highlight it and view the associated results in the pane on the right.
To specify the elements that will be considered in the calculation
- Highlight the scenario icon in the tree view.
- Click the Pumps tab. All of the pumps in the model are listed in the table. By default, all of the pumps in the model are included in the energy cost calculations. To disregard a pump during the calculation, clear the Include in Energy Calculation? check box associated with it.
- Assign Energy Pricing to each pump that will be included in the calculation. Choose an energy price definition for each pump from the list in the Energy Pricing column. If no energy price definitions have been defined, click the ellipsis button to open the Energy Pricing Manager. See the Energy Pricing Manager topic for more details on creating a new energy pricing definition.
- Click the Tanks tab. All of the tanks in the model are listed in the table. By default, all of the tanks in the model are included in the energy cost calculations. To disregard a tank during the calculation, clear the Include in Energy Calculation? check box associated with it.
- If there are VSPB (variable speed pump battery) elements in your model, follow the instructions for Pumps above to specify which VSPBs are to be included in the calculation and to assign energy pricing definitions to them.
- If there are Turbine elements in your model, follow the instructions for Pumps above to specify which Turbines are to be included in the calculation and to assign energy pricing definitions to them. Since turbines generate power, the results for turbines will be negative numbers.
