Utilities

The Utilities tab shows the utilities that may be purchased to fuel the plant operations, along with pricing and constraints for these utilities.

Note: Utilities are a type of property and must exist in the global reference data before they can be used. Like other properties, utilities have units of measure categories to allow conversion between different units of measure (so for example kWh can be transformed to MWh). Utilities, like other properties, must be published from other AVEVA tools such as Assay.

To add a utility:

1. Click the Add Utility button in the Manage group of the Home ribbon tab. The Add Utility Purchase dialog box opens.

   

2. Select the required utility from the Utility menu and click OK. A row for the new utility is added to the table.

3. If desired, edit the name of the utility in the Purchase/Tranche Name column.

4. Enter the price for the utility in the Price column, and select the desired unit of measure.

5. If desired, enter a Minimum, Maximum or Fixed constraint, and choose the appropriate unit of measure in the Utility UoM column.

6. Optionally, enter a Priority for the utility. If you set a priority, ensure that the utility has no active minimum or fixed constraints, and the solution is not locked. In addition, make sure you have an active Maximum constraint.

To add a tranche for an existing utility:

7. Select the row corresponding to the utility for which you want to add a tranche. Click any cell to select the row.

8. Click the Add Tranche button in the Manage group of the Home ribbon tab. A row for the new tranche is added to the table.

9. Edit values in the new row as you would for a new utility.

10. Optionally, enter a Priority for the tranche. If you set a priority, ensure that the utility has no active minimum or fixed constraints, and the solution is not locked. In addition, make sure you have an active Maximum constraint.

To edit a utility or a tranche, make the desired changes in the corresponding table row.

To delete one or more utilities or tranches:

11. Select the utilities or tranches to be removed and click Delete in the Manage group of the Home ribbon tab.

12. Click Yes to confirm that the utilities or tranches should be deleted.
