CLEAN CITIES ALTERNATIVE FUEL PRICE REPORT OCTOBER 2009

PROPANE
Average prices for propane are illustrated in Table 8, grouped by region. Information on prices for regular gasoline as provided by representatives from Clean Cities is also shown. These prices were collected from across the country from Clean Cities Coordinators, fuel providers, and other stakeholders on a voluntary basis. About 160 propane prices were collected in this reporting period.
As Table 8 illustrates regionally, propane prices are somewhat higher than gasoline in some regions and lower in others. Overall, propane was about 5 cents per gallon more than gasoline. Based on calculations of standard deviation in prices, it can be seen that propane prices for vehicle use seems to have varied more than gasoline prices during this sampling period.7
The map to the right illustrates some cost differentials between propane and regular gasoline on a per-gallon basis, based on differentials between propane prices and gasoline prices for each state (versus the regional averages illustrated in Table 8). In this map, negative numbers represent costs for propane lower than costs for gasoline, and positive numbers represent propane prices higher than gasoline. States not highlighted with a color did not have any propane data points in the current report. Propane prices were most favorable in parts of the Lower Atlantic and the West.
