Chart 2 is domestic propane. It was extremely low at the beginning of the year. As we predicted, it recovered during preparation for this winter and, by June, was trending above last year’s rate. But now that much of the preparation for winter is complete, domestic demand is once again trending below last year.
Remember that the demand number in Chart 2 is a calculated number. The U.S. Energy Information Administration does not collect data on domestic demand. Instead, it collects data on propane imports, exports, production and inventories. It then infers what demand must have been based on the other data points. If the data is off in other areas, it skews the domestic demand number as well. We often see a huge jump in exports, resulting in a corresponding fall in domestic demand and vice versa. That is why we focus on the trend lines in Charts 1 and 2 rather than the weekly numbers. Combining export and domestic demand is useful as well.
