The implementation of AB-32 is already increasing the price of fuel in California and LCFS is forecast to have a larger impact. My goal is to visualize the cost impact when LCFS becomes mandatory 1 Jan 2015. The data sourcea are the fuel prices as posted on the Energy Information Administration web site.
This first chart shows West Coast Minus California (red) vs California (blue).
This second chart is a zoom into the top right of the above chart above, to show the widening gap in more detail.
One of the issues is that Hawaii and Alaska are included in the PADD 5 cohort of prices, which is inflated by transportation costs.
This chart shows PADD 4 which is the Rocky Mountain States: Colorado, Idaho, Montana, Utah, Wyoming (blue) vs California Diesel prices (red). I cannot compare PADD 4 gas prices as Rocky Mountain refiners do reformulate gas like refiners are forced to do in California. How ever diesel prices are comparable. Diesel prices will also be impacted by LCFS.
Note: This charts will be updated monthly under the CA Fuel Tab above, including a more detailed analysis of the data.
