Last Thursday, a fire at the aging Chevron refinery in
Pascagoula, Mississippi, temporarily sidelined one of the 10
largest oil refineries in America. Although Chevron says most of
the refinery is undamaged, it has not restarted yet.
The Pascagoula refinery celebrated its fortieth anniversary in
2003. It makes gasoline and jet fuel, among other products, from
crude oil. As news of the fire spread, the price of oil jumped $2
per barrel to $71 on commodities exchanges.
Hurricane Katrina showed how shutting only a few refineries can
make a large impact on prices American consumers pay for gasoline
and heating oil. As the refineries and oil platforms near the Gulf
of Mexico struggled to recover after Katrina, American politicians
asked if we had enough oil refining capacity.
Because of stricter environmental standards, there has not been
a new refinery built in the United States since 1976, while the
number of oil refineries has shrunk dramatically from 301 to 149.
Refineries that still exist have to try to run near full capacity
to keep up with American demand. Some areas require special
gasoline formulations to reduce auto emissions, which drives up
prices everywhere.
Self-serving statements from the National Petroleum Refineries
Association say that American oil refinery capacity has
increased. “With the amount of new capacity U.S. refiners
have added at existing facilities since 1994, it’s as though the
industry has been building a new, world class refinery each year,”
said Charles Drevna, executive vice president of the association.
He says refining capacity has increased by 177,000 barrels per
day.
If that is true, shouldn’t the price of gasoline and heating oil
be lower? The U.S. Department of Energy tracks oil refinery output.
While the amount of gasoline supplied by American refineries is
about 285 million barrels per month, the amount of refinery
capacity devoted to gasoline production has fallen by 10 percent
from 1983. The amount of fuel oil produced by American oil
refineries has fallen by five percent since the record high
production of about 135 million barrels per month in 2001.
As we witnessed after Hurricane Katrina and the Pascagoula
refinery fire, American refineries are fewer in number, so a
disaster at even one drives up crude oil prices. Even tiny swings
in the price of crude oil increase the cost of finished products
consumers buy. Expect candidates for President of the United States
from both major parties to argue for more oil refineries or at
least repeal of the laws of supply and demand.
