Bulk shipments can be entered in two ways:
- As a bulk shipment based on the actual delivery dates (Example #1 below)
- As a monthly estimate (Example #2 below)
When creating a meter for fuels received in bulk you can select “Enter as Delivery” and the tool will assume that the bulk fuel was used in the month it was received/entered. For some users that will be most accurate.
For others, using a monthly estimate will be more accurate. To choose this approach, uncheck the “Enter as Delivery” box, when creating a new meter (note: you can't edit this later).
Example #1 - Your building receives fuel oil only in the coldest winter months. You usually get shipments in December, January, and February, and they are used, more or less, within that month. Entering the bulk fuel for the month it is received, and checking "Enter as Delivery" will probably result in the most accurate metrics. For this example, if you don't get a delivery in a month, it is assumed you didn't use any that month. You do NOT have to enter a bill for months with zero usage.
Example #2 -Your building receives propane for heating. You heat about 9 months of the year, and get 2 or 3 propane shipments per year. For each shipment, you determine an approach to allocate across the months it is used. You may make this determination by:
- dividing evenly across all months
- using a gauge/reading off of your tank
- estimating the usage based on the weather and your heating demand.
If you chose this approach, what is most important is that the totals you enter for each individual month add up the total used between deliveries. The metrics in Portfolio Manager are based on annual, not monthly, energy. So, what is most important is that your annual totals are correct. To take this approach you will need to uncheck "Enter as Delivery" box so Portfolio Manager knows you are breaking up your bills and you will need to enter zero usage for any months where you didn’t use fuel so that you have data covering the entire 12 months. If you are taking this approach, as long as the values you enter for each month add up to the totals received between deliveries you do not need to check the “Estimation” box for any entries.
