We are back up to respectable today.
Just for the pure joy of it, I have done a little calcuation on the issue of "reinvestment rate", per the comment the other day in the "bush calls for new refineries" thread.
Dantespeak is actually a professional in this area, so he can help us if we are too far off. Plus I have not done this calculation in a long time.
We know from our observations of the last several refinery projects that currently, it takes $20,000 per BOPD capacity to build a refinery. So, for a 100,000 bpd refinery, we can expect to pay $2B.
At 95% utilization, we can expect to produce approximately 35 million barrels per year. Note that TSO would like to get between 93 and 95% utilization this fall, so this is a little aggressive.
So, at what refining margin could we expect to make enough money to justify risking $2B on more capacity?
I have estimated capital costs by using the excel (PMT) function, using 15% as the "hurdle rate", $2B as the investment, a 15 year investment time frame, and a zero salvage value. At this rate, the annual C of C is about $300 million.
The net of the gross manufacturing margin (300 million barrels times the gross refinery margin minus the cost of capital) is the annual return. The present value of the annual returns for 15 years at 8% interest (which is TSO's average interest rate) is obsiously dependent on the refinery margin, but I used MS-goal seek to arrive at the margin at which the project will break even, (the income stream is equal to the value of the investment) and it is about $15 per barrel.
Obviously the real calculation needs to be made both before and after taxes, considering depreciation and the tax effects of the interest payments, but I do not want to make this overly complicated, because I am just some guy on the internet and this is close enough.
But to make a long story short, anything above $15 per barrel is approximately enough to justify the new refinery, and anything below that is not enough. Obviously, a lot below this, like about $6, is enough to cause TSO to lose money, which is what happened in the last quarter. The frequent viewers of PO.com may have observed that the "refinery expansion" announcments have completely stopped for about the last 5 months. This is why.
So, unless TSO is confident that they will consistently get greater than $15 per barrel refinery margin, they will just run what they have and not worrry about it. For an outfit like TSO, with only 660,000 bpd capacity in the whole company, if they expand their refinery, they have an excellent chance to bankrupt the whole company, if the price turns around and they cannot make enough to pay the financing amount.
So the government can do several things to help this process along if they choose: The most popular is to give out various tax breaks, extra depreciation benefit, or some combination, to lower the risk. This would lower the effective refinery margin needed to make the investment. However, some of us believe that the government has no business doing this, because it amounts to subsidizing the oil companies, and also, that the oil companies are evil in some way, and are exploiting us, etc. etc. so the taxpayers should not be doing this.
The marxists among us may propose fixing the price of gasoline and/or crude oil at some rate so that the risk can be reduced, and ensure a consistent return on investment. In the US, we did this with utilities for a long time. This never works for long, though. You end up with shortages, because there will always be people complaining that the rate is set too high. A lot of the idiot nations which have tried this have recently run into a serious problem in this regard.
All I can say is, at the current economics, it is really iffy as to whether the US refiners like TSO are willing to accept the risk to expand the refining capacity, so it is quite likely that we will go for several more years of being short on fuel every spring, before the refinery margin finally gets to the point at which these guys can responsibly run their business.
Here is my little spreadsheet:
$this->bbcode_second_pass_quote('', '$')20,000 dollars per BOD cost of plant
100,000 BOPD plant size
$2,000,000,000 investment needed
34,675,000 annual production (barrels)
14.82 dollars/barrel ref margin
$513,771,970 Gross Margin (annual)
($297,420,961) COC 15 yrs/13% hurdle rate
216,351,009 PBT
$2,000,000,000 PV (15 yrs/8%)
0 NPV
p.s. The giant refineries supposed to be under construction in Saudi do not follow these same rules of economics, since they are getting their oil "at cost", and not at the world price. Also note, that if you build a refinery that takes heavy/sour crude oil, you are a little better off because your overall margin is higher, since these grades of crude are cheaper.
