Hi Paul, Some new facts on coal. I'm a Sierra Club volunteer in Michigan. frank
If these trends continue, the economy
of many states and the entire US may be at risk because of our over-reliance on
coal to generate electricity. The following are details I researched.
Feel free to use them.
Disturbing
Coal Facts and Trends, June 2011
1. The Delivered
Price of Coal Increased Three Times Faster Than Inflation in Past 5
Years
2. Cost of
Transporting PRB Coal is Three Times Greater than Its Mining Costs
3. Oil Has Twice
the Impact of Mining on the Cost of Delivered PRB Coal
4. States Dependent
on Coal Had the Highest Electricity Price Increases in Past 5 Years
5. US Coal Mining Productivity
Peaked in 2000 and Declined 20% Since
6. Other Cost Pressures on Coal
1. The Delivered
Price of Coal Increased Three Times Faster Than Inflation in Past 5 Years
·
A common measure of the price of coal delivered to US utilities in
dollars per million Btu (MMBtu)
to account for the different coal Btu values.
·
In the past 10 years, the delivered price of coal increased
96% from $1.20 in 2000 to $2.35 in March 2011.
The US
inflation increased was 30% during this time
2. Cost of
Transporting PRB Coal is Three Times Greater than Its Mining Costs
·
The
price of Powder River Basin (PRB) coal from Wyoming has fluctuated from roughly $7 a ton
to $20 a ton in the past 10 years.
·
In
June 2011, the mine mouth price of PRB coal price was stable at $12.40 - $13.00/ton.
·
Assuming
PRB coal is shipped (rail and boat) 1,600 miles to Midwestern utilities; the
cost of transportation alone is $36 (a 2011 estimate).
·
Add
the $12 PRB price to $36 transportation charges results in a delivered price of
approximately $48.00 per ton. $36 divided by $48 = 75%.
·
The
cost of PRB coal mine mouth is only 25% of the price of delivered coal.
This
estimated transportation charge could be well underestimated. It does not
reflect new 2011 contacts, recent diesel price increases and Burlington
Northern’s attempt to recoup Warren Buffett’s overpayment for the purchase of
all BN stock in 2010.
Only
two rail lines ship PRB coal out of Wyoming,
Burlington Northern and Union Pacific. They share the “Joint Line” which runs
parallel to the Powder
River Basin (almost a monopoly?). This is the busiest 100 miles
of track in the world, carrying 130 trains per day.
3. Oil Has Twice
the Impact of Mining on the Cost of Delivered PRB Coal
·
It is estimated that the price of diesel fuel accounts for half of
the price of coal transportation
·
The estimated $18 cost of oil (half of the $36 transportation
charge per ton) is 50% greater than the cost of PRB coal cost of $12 per ton.
·
The EIA conservatively forecasts the price of oil will increase
roughly 3% a year faster than inflation (Inflation +2% a year, oil an
additional +3%, equals +5% a year increase in the price of oil). Essentially, the
price of delivered coal may increase at a rate much faster that of inflation
4. States Dependent
on Coal Had the Highest Electricity Price Increases in Past 5 Years
·
The
retail price of electricity in the US increased 22% over the past five
years ( from 8.1¢ in 2005 to 9.9¢ in 2010)
·
However,
two regions very dependent on coal (and located further from PRB), saw their
electric bills increase the most since 2005. East South Central (TN KY MS AL) saw
their rates increase 34% (from 6.14¢ to 8.21¢) and East North Central (MI OH IN
IL WI) had a 32% increase (from 6.87¢ to 9.09¢)
5. US Coal Mining
Productivity Peaked in 2000 and Declined 20% Since
·
According to the Energy Information Administration (EIA), improved
mining technology and the shift toward more surface-mined coal promoted
dramatic improvement in productivity from the Nation's mines from 1978 through
2000 when an average 7.0 tons of coal
was produced per employee per hour.
·
This 20% productivity decline happened in spite of improved
technology, cost cutting efforts and more strip mining.
·
The biggest productivity decline, a 5.9% drop, occurred from 2008
to 2009 (the last year reported)
·
2009 coal mining productivity dropped in all parts of the US
especially for Western coal which dropped 9%. Of note: PRB surface mining
productivity declined 7.5%, and Montana
surface mining dropped 10.4%. http://www.eia.gov/cneaf/coal/page/acr/table21.html
·
Most of the PRB coal mining productivity decline probably can be
attributed to increasing overburden (the amount of dirt and rock above the coal
seam). It appears the typical PRB overburden is about 200 feet thick and
doubling to about 400 feet thick in 8 years – a productivity killer. http://www.blm.gov/pgdata/content/wy/en/info/NEPA/documents/cfo.html
6. Other Cost Pressures on Coal
In addition to declining productivity and escalating delivery
costs, there are other reasons the price of coal could continue to rise at a
fast past:
·
China and India
are buying US
coal mines and a new coal-export port facility on the
US West Coast
·
As Appalachian coal fields are depleted, Eastern and Midwestern
utilities are increasing their purchase of PRB coal. The increased demand will
put upward pressure on the price of PRB coal and will also further increase
rail congestion and costs for coal shipments.
·
Utilities planning to burn petroleum coke need to consider
that the price of delivered petroleum coke has increased 38% from 2009 to 2010
and increased 56% in the first quarter 2011 compared with the same period last
year. At $3.09 per MMBtu, pet coke is even less of a value than March 2011 coal
at $2.35 per MMBtu. http://www.eia.gov/cneaf/electricity/epm/epm_sum.html Table 4.12.B
Helping
to somewhat reduce demand for coal and cost pressures are:
·
Some
utilities may close coal plants to avoid increasing SO2, NOx, mercury and other
pollutant compliance costs
·
Environmentally progressive companies like Johnson Controls, Haworth, Steel Case and Wal-Mart have set high goals to
reduce their carbon footprint. This will require their electric suppliers to
produce less electricity using fossil fuels and more from renewable sources.
If these trends continue, the economies of many states (and the US) will be at
a disadvantage because of our over-reliance on coal to generate electricity.
This argues for more energy efficiency, renewable energy and natural gas
generation to diversify their fuel supplies. We have too many eggs in one
basket.
