Who Wins in a Competitive Power Market: Gas? Coal? or Rail
& Mining Interests? Deregulation promises lower prices for
electricity. But will consumers see those savings on their monthly bills? The
answer may come from within the coal industry, which still holds a dominant
position in electric generation, even with all the recent enthusiasm for
gas-fired plants.
Those who ignore coal to focus on natural gas for
electric generation should proceed carefully. Granted, gas may attract the
lion's share of new construction. It may even define a cap on prices during
periods of peak demand. Gas-fired generation typically enjoys substantial
capital, environmental and operating advantages to coal and is expected to
dominate installation of new capacity. Nevertheless, coal should continue to
supply much of the base load generation in many markets throughout the
country.
Coal enjoys a cost advantage over other fossil fuels
in power plant operations, as measured in dollars per delivered MMbtu. That
margin--the gap between gas-based clearing prices for electricity and the lower
cost of producing coal-fired power--represents potential economic value. And it
is that economic value that lies vulnerable to appropriation by other interests
that occupy commanding positions in the coal fuel cycle.
Some coal-fired generation capacity remains
underutilized. Its use can be expanded, however, through open-access
competition. This access to markets will make it easier for cheaper, coal-fired
generation at one utility to displace the more expensive gas-fired generation
of its competitor. These savings should flow through to retail power customers.
Often overlooked, however, is whether up- stream suppliers will appropriate
these savings. In fact, the chance for appropriation appears quite substantial,
particularly due to the increasing concentration of market shares in coal
transportation (meaning railroads) and, to a lesser extent, in coal supply
industries.
Those who would ask whether consumers will gain from
electric competition would do well to start with the economics of coal use in
power generation.
The Growing Concentration in Transport and
Supply...
Whatever the virtues of natural gas as a fuel for electric
generation, a substantial investment still exists in coal-fired capacity. Coal
accounts for more than half of domestic electric generation, despite a lower
share of available capacity. 1
Nevertheless, some of the underlying conditions that
contributed to current favorable coal economics are starting to erode. Not only
does coal-fired generation depend on the coal mining industry, it also depends
on the railroads for transportation. Specifically, there has been a substantial
consolidation among the railroads that haul coal, and increasing concentration
in the coal mining industry.
Consolidation is especially apparent among the
railroads. In 1990, there were five major Western coal-hauling railroads: the
CNW, the Burlington Northern, the Union Pacific, the Southern Pacific, and the
Santa Fe. Those five carriers have now been consolidated into only two Western
railroads, The Burlington Northern Santa Fe and the Union Pacific/Southern
Pacific, which together control 96 percent of the Western railroad coal
traffic. This situation is hardly conducive to long-term competition.
The success of the CNW (since acquired by and merged
into the UP) in capturing business from the incumbent Burlington Northern has
led to some abatement in competitive conditions. CNW paid more than $300
million to acquire, construct and rehabilitate trackage to serve the Southern
Wyoming portion of the Powder River Basin of Wyoming and Montana (SPRB), which
the Union Pacific largely financed. CNW and the Union Pacific acted
aggressively when they first entered the SPRB to attract sufficient traffic
volumes to justify their investment. Over time, their share grew, and in 1994
they originated more coal from the SPRB mines than Burlington Northern. Since
the market has achieved "maturity," competition is apt to be less
aggressive.
Railroad mergers are not confined to the West. CSX and
Norfolk Southern (both products of large, 1980s mergers) are now in the process
of carving up Conrail. Soon, two major carriers in the East will control 92
percent of the Eastern railroad coal traffic-- as there are in the West.
Abundant speculation exists that two transcontinental
mergers will shortly follow the Conrail merger--leaving only two
transcontinental railroads and a number of much smaller carriers. While the two
large railroads are poised to compete with trucks for traffic that can move in
different transportation modes, commodities that move primarily by rail--of
which coal is the most prominent--are unlikely to benefit from such an industry
structure.
Less conspicuous, but still very significant, is a
growing consolidation among coal producers. For example, assuming consummation
of recently announced transactions, the number of major producers in the PRB
will be reduced to four. Peabody, the largest coal producer in the United
States, will have 30 percent of PRB production, and Kennecott will have 20
percent, with Cyprus Amax (the second largest domestic producer) and Arco
constituting the rest of the major PRB producers.
Substantial consolidation has also taken place in
recent years within the coal industry as a whole. From 1976 to 1991, the number
of mines was cut in half, but total production increased by 45 percent, and the
average mine size tripled. By 1991, only 7 percent of the nation's mines were
producing two-thirds of U.S. coal. The trend has continued. For example, the
second largest producer (Cyprus Amax) was formed through the 1993 merger of the
third and 14th largest producers.
Pricing Implications of Consolidation...
Consolidations within the railroad and coal industries
potentially enhance the leverage of those firms with their common customers--
electric utilities. Leverage can take a range of forms including outright
acquisition of generating plants, commercial arrangements that tie the price of
the coal or transportation directly to the price received for power generated,
or rates that reflect the expected level of the utility's demand load. These
arrangements all exist today.
In general, the coal industry is still much less
consolidated than the railroad industry. And although aggressive competition is
prevalent, coal's financial health is significantly less robust. Perhaps
because of its more competitive nature, the coal industry has acted faster to
adopt innovative approaches to pricing.
Some coal companies have formed power marketer
affiliates, and are considering buying coal-fired power plants, including those
in bankruptcy or being divested in utility restructuring. Cyprus Amax, over the
past year and a half, has entered into alliances with approximately 12
"leadership utilities" under arrangements. These arrangements include "coal
tolling," whereby the coal price is tied to the price that the utility receives
for power generated from the coal. Other coal companies and coal brokers have
reportedly entered into such arrangements.
Implications for Deregulation...
As noted, open access and the accompanying increase in
competition in generation may permit railroads and coal suppliers to extend
into the generation industry. To the extent that coal-fired generation is
cheaper than gas-based market clearing prices, the gap is potentially available
to consumers through lower power rates, utilities through higher power rates,
and railroads and coal suppliers through higher transportation and coal
prices.
Those entities with the highest concentration--the
railroads--are best positioned to exploit the opportunity. Railroads can
increase their rates (particularly compared with their declining costs of
providing service) without losing market share, while rail- delivered coal
remains the cheapest fuel option for generation according to
marginal-cost-dispatch principles.
Of course, there will be some exceptions. Some railroads
will continue to compete vigorously. However, such situations are likely to
moderate when the competition is confined to two carriers in either the West or
the East (or nationally, should there be transcontinental mergers).
Undoubtedly, rates will decline for some from levels established in the 1970s
or the early 1980s before the entry of the CNW into the SPRB. Deregulation will
give utilities added incentive to control fuel costs. Nonetheless, where a
power plant remains captive to a single railroad, that railroad will have
little incentive to bring the plant's delivered fuel costs significantly below
that of gas-fired dispatch or alternative power sources. This means that
railroad contribution margins should remain substantial. 2
A January 1997 report by Salomon Brothers, prepared with
assistance from RDI, Utility Deregulation's Impact on the Railroads,
claims that deregulation will result in a loss to the railroad industry of 0.9
percent to 1.3 percent of its coal revenue (or 4 percent to 6 percent of
operating income forecast). However, the report fails to quantify Western coal
growth, coal-fired electricity growth, continuing improvements in railroad
productivity, and the consequences of duopoly pricing. Any of these
considerations could more than offset the claimed reductions in revenue and
income.
The Salomon Brothers report attributes much of the
projected decline in rail revenues to the expiration of older, above-market
contracts of Burlington Northern Santa Fe and Norfolk Southern. Even absent
utility deregulation, the railroads would feel considerable pressure to reduce
such rates as older contracts expire. The fact those rate reductions are
accompanied by deregulation hardly means the changes are caused by
deregulation. Significantly, both Burlington Northern, Santa Fe, and Norfolk
Southern have taken vigorous exception to the report's analysis.
The report also discusses such possibilities as
"coal-by-wire," by which a utility receives coal-fired generation from another
utility's power plant, thus providing an alternative to high coal
transportation costs. The coal-by-wire scenario presumes a surplus of economic
coal-fired generation and transmission capacity. Even before open access,
coal-fired plants with low delivered costs had ample incentive to achieve high
capacity use. One must question the real potential for coal displacement to
occur in the magnitude claimed by the report. Displacement is more likely to
involve coal replacing more expensive gas, meaning increased volumes and
revenues for the railroads. In short, railroads are posed to be net winners
from utility deregulation.
Coal Generators Should Proceed with
Caution...
Those who posit improved consumer welfare inevitably
follows increased competition would do well to consider that other sectors may
compromise competition in one sector. This is especially likely to happen when
one sector is dependent upon another, highly concentrated sector, as is the
case of the coal and railroad industries. Likewise, utilities with coal
generation facilities should approach their transportation and supply
arrangements in the open access era with care. The favorable trends of the past
10 or 15 years will not necessarily continue.
The time may also be ripe to reassess the regulation of
rates for railroad transportation of coal. For the past 20 years, there has
been a strong drift toward reliance on competition, accompanied by
ever-increasing railroad consolidation, which could culminate in two
transcontinental carriers.
Given the consolidation that has occurred within the
rail and coal industries, and robust financial condition of the railroads, one
must question whether trends will continue to be mutually advantageous. In
approving the various rail mergers within the past few years, the Interstate
Commerce Commission and its successor, the Surface Transportation Board, have
generally refused to grant relief to utility shippers, primarily on the grounds
that merger conditions should not be used to create new competition.
The board also recently rebuffed efforts by several utility
shippers to confine rate challenges to the captive or "bottleneck" portion of a
longer movement that contained competitive and captive segments. Permitting
bottleneck rate challenges would have allowed utilities to benefit from
rail-to-rail competition where it exists. The board's decision enables
bottleneck carriers to appropriate the benefits of the available competition.
These developments limit the potential of electric utilities to be successful,
and to confer the benefits of production efficiencies on their customers, in
the emerging competitive environment.
1. Energy Information Administration,
Annual Energy Review 1995 (July 1996). 2. The
Surface Transportation Board has the authority to provide rate relief where a
railroad has market dominance over a captive shipper. The governing statute
prevents the agency from setting a rate that is less than 180 percent of the
railroad's variable cost of providing the service. Variable cost represents
average variable, and not incremental, cost of service, including a return on
investment. The result is a generous return to the carrier, particularly
compared to a utility that can sell power at only a small mark-up to
incremental cost. |
Coal's History of Dependence on
Transportation
Health of Industry Linked to Railroads... Generating
coal power requires a supply of coal and transportation to the power plant.
While some coal-fired plants are located at the minemouth, and other coal moves
by barge or truck nearly two- thirds of all domestic coal moves to the
generating plant by railroad. 1 Favorable developments over the
years in coal transportation have contributed to the present favorable
economics of coal-fired generation.
In the early and mid-1970s, many utilities turned to
coal-fired generation to meet increasing customer loads. This increased demand
resulted from the OPEC oil embargo, natural gas curtailments and, particularly,
federal energy and environmental mandates such as the Fuel Use Act, which
restricted use of fossil fuels other than coal in new power plants.
2 The energy industry responded by opening new surface mines for
low-sulfur coal, particularly in the Power River Basin of Wyoming and Montana
(PRB).
The initial availability of PRB coal was nonetheless
very constricted. Utilities had to enter binding contracts, despite the
restricted supplies, to obtain approval and financing for their new power
plants. The result was a substantial run-up in coal prices.
Developments within the railroad industry also
contributed to the high, initial delivered costs for coal. Until 1984, only a
single carrier, the Burlington Northern Railroad, served the PRB. Utilities
sought to protect themselves by entering into letter rate agreements with the
Burlington Northern. However, the railroad industry experienced substantial
financial difficulties of its own during the 1970s, and deregulation emerged as
the solution to those perceived difficulties. Burlington Northern, along with
various destination carriers, took advantage of the new price flexibility by
increasing coal transportation rates.
Fortunately, these adverse trends reversed themselves
in the 1980s. New PRB mines came on line and eventually achieved substantial
output and associated productivity gains. 3 Increased productivity
and competition among the mines have translated into nominal PRB mine prices
that approximate those before the OPEC oil embargo in 1973.
Rail developments also have helped utilities. In 1984,
the Chicago and North Western Railroad began serving mines in the Southern
Wyoming portion of the PRB and, over time, created meaningful competition with
the incumbent Burlington Northern Railroad. Notable increases in volumes
4 helped the railroads achieve substantial productivity gains in
their coal movements. Those utilities with viable competitive options
benefitted form improved rail productivity. Nonetheless, trends in rail rates
have generally not tracked declines in the railroads' costs of providing
service. Rail rates of PRB coal often exceed the cost of purchasing the coal
from the mine.

Mixing Coal, Gas and
Marketing...
How U.K.'s Energy Group PLC would deal with captive
transport... The antidote to captive markets in fuel transport may lie in
vertical integration combining coal and natural gas properties with electric
distribution assets and power marketing skills to open up new pathways for
energy delivery.
That seems to be the strategy of The Energy Group PLC,
a newly formed public limited company incorporated in England and Wales after
its "demerger" (spinoff) from Hanson PLC. With Derek Bonham as its executive
chairman, The Energy Group will own Peabody Coals, the largest coal producer in
the U.S., and Eastern Electricity, a British regional electricity company that
serves 9 percent of the U.K. market, according to Bonham (2 million meters; 7
million people).
When Hanson announced the demerger, the U.K. press
reported the energy Group was ready to acquire power plants in the U.S.* Later,
on March 10, the Energy Group announced plans to acquire Citizens Lehman Power
LLC, one of the top five U.S. power marketers, giving it a diversified
portfolio of assets and expertise.
U.K.--Playing Both Sides. In the U.K., Eastern
has added coal to its gas-fired portfolio.
"At Eastern," says Bonham, "we decided [we] needed to
be on both sides of the pool. We started in generation by building some
combined-cycle turbines, but we acquired 5 coal-fired projects from National
Power. So we have something like 6500 megawatts of capacity-about 10 percent of
the market. We can decide 48 times a day whether to run gas plants or coal
plants, depending on price.
"We actually trade about 17 percent of the market in the
U.K., So if you look at our experience in the U.K., we are moving toward
vertical integration."
U.S.A--Giving Price Relief. How will the Energy
Group integrate its coal assets in the U.S. with its overall strategy? "Just
because we are buying generation plants in the U.S., it doesn't mean that we
will be buying [coal] plants served by Peabody," says Chris Farrand, vice
president, corporate affairs for Peabody Holding Company Inc., parent company
of Peabody Coal Co. "We might do some novel deals where we might lease some
plants and then sell the power output. We signed an interesting deal with
Enron. We will supply gas for the turbine and then take the output."
Farrand continued: "At Peabody, we've done some
experimenting with customers who have excess [generating] capacity. We hope to
acquire a power marketing company. With the marketer, and with electric
transmission agreements, we may be able to give price relief to the customer by
taking some of the excess capacity and marketing the power.
"We may be able to ship power to the customer instead
of shipping coal long distance." --BWR
