Start the Energy Wizard Setup program, click on the large button 'Supplier'. When the 'Supplier' form appears, set it up as required, click on the 'OK' Button to save the changes and then click on the 'Tariff Setup' button. Select the 'Peak Energy' tab and the following will be displayed.

Here you can setup how the Energy Wizard will calculate the Peak Energy for the month and also if it will cost that peak.

Please note that, in energy terms, to find the single highest peak you would take the following steps:

• Find the period that has the highest energy usage for the month.
• Take that value and calculate it back so that it represents an instantaneous energy flow based on the length of the period.

When referring to peaks, the peak is not actually the highest instantaneous rate but the highest integrated average rate. For example, given that the highest energy usage has been recorded at 120 kWhrs for a 30 minute period. Then the Peak (integrated average) would equal 120 kWhrs / 0.5 hrs = 240 kW. Note that the actual highest instantaneous rate experienced during this period would have been higher than 240 kW.

• Peak Type for all Power Bills: - Select the Peak Type. This could be set to the single highest peak for the month, or could be set to an average of up to the 24 highest peaks for the month.
• Main Cost Center Peak From: - Select where the Main Cost Center, Center 0, will derive its peak. The options are from either itself or from another Energy Wizard Monitor Tag. This option is designed to cater for main incomer power meters which have available both kW and kVA. Also to coincide with Suppliers that base their charges on peak kVA units.
• Main Cost Center Power Factor: - This option is only available if the 'Main Cost Center Peak From' is set to 'Own Energy Data'. Under these conditions, if an average site power factor is known, then this can be entered into this text box. If kVA is not an issue for your site then set this value to 1.
• Apply the Main Cost Center Power Factor to all Power Bills: - To select 'No' will result in all Sub Cost Centers and Tag Power Bills using their own data to calculate the peak with no adjustment for power factor. To select 'Yes' will result in all Sub Cost Centers and Tag Power Bills using their own data to calculate the peak but with it adjusted by the power factor. This could be quite significant if the peaks are being costed.
• Do you wish to charge the Peak: - If the peak for this supplier has a charge associated with it then select 'Yes', otherwise select 'No'.
• Peak Rate: - Enter the amount that the peak is to be charged by into the text box.

Please note that if you have a number of TOU Slots which are similar then you may find the 'Copy', 'Paste' and 'Undo' buttons useful in speeding up the process.
