Question about sector 156 - petroleum refineries
Hello, I have built a model consisting of 5 counties in Texas and I tried to enter fuel sales for this region in sector 156- petroleum refineries as an industry change and this sector does not exist in this region. So, I then added the sector, entered my fuel sales and changed the margin to "Yes". However, when I change the margin, analyze the scenario and examine the results, the results do not seem logistical. The results are showing much larger numbers than in the original setup. I was wandering if you had any explanation as to why the numbers in the results are so much different and also, if you had another way of handling the problem of this particular sector not existing in the region. I would appreciate any help you could provide.
Thanks,
Dan

Hi Dan, We would recommend going back and rebuilding a new Model that uses the unmodified base data. Unless you have a reason to believe that you have petroleum refineries in your region, which are unrepresented in the data, and have a value for that production, you would not want to add this Sector. You can still Margin the Sector though even if it doesn't exist in your region to reflect your petroleum sales and grab a large piece of the impact. One key aspect a lot of people miss, is that the forget is to set the LPP on the Event to SAM Model Value. And then use the Margin Edit screen to change the Retail Gasoline Station back to LPP 100%. This is a key step to not overestimating the impacts.
