Economists Flunk Enviro Report On Economics
Of Dam Breaching
Northwest Fishletter
March 8, 2007
A panel of independent economists that provides
reviews for the Northwest Power and Conservation Council has thoroughly
panned a report that says the region could save money by taking out the
lower Snake dams.
The panel says the report, titled Revenue
Stream, underestimates the cost of
replacement power by so much that it "invalidates" the
report's conclusion.
The Independent Economic Analysis Board was asked by
Council members to take a look at the report, which was released
last November.
The panel submitted its scathing review to the Council
last week, noting that the report was not the product of peer review or
an open public process, and that "many of the sources of the report
came from other reports that were also not products of open process and
peer review.
The IEAB said the report contained several other major
methodological failures, including not discounting future benefits and
costs of dam removal, and questionable accuracy of agency fish budgets.
Perhaps its biggest flaw, the board said, was reliance
on a 2004 report by Idaho-based economist Don Reading that estimated
huge benefits from a fully restored recreational fishery.
The panel panned Reading's report in 2005 for his
pie-in-the-sky estimates. It found that Reading "had made a number
of methodological errors which seriously biased his benefits
upward." Reading had said fishing benefits could top $500 million a
year.
The panel said the report's estimates of benefits to
commercial fishermen were open to question as well, since they were not
peer-reviewed. The numbers came from the Institute of Fisheries
Resources, a group associated with one of Revenue Stream's
sponsors, the Pacific Coast Federation of Fishermen's Association.
The economists said it might be time to do a follow up
to the Corps of Engineers' EIS on impacts of removing the four lower
Snake dams that would fix weaknesses in that huge analysis, and reflect
the "many changes" in the economy, transportation systems,
power generation and the state of fish recovery efforts.
But the panel failed to mention the misuse
of a 2004 report commissioned by American Rivers, one of Revenue
Stream's own sponsors, which was used to peg the costs of upgrading
railroads to be between $18 million and $231 million. The consulting
firm that completed the study actually estimated that costs of changing
over from barge transportation to rail could add up to more than $1.4
billion. The consultants complained at the time about their work being
misrepresented by their client.
Other cost estimates were lowballed as well. BPA
spokesman Scott Sims said the lower Snake dams generate $400 million to
$550 million in power every year, which is about three times the cost of
replacement power cited in Revenue Stream if the dams were
breached. BPA said when accurate numbers were used in the calculation,
net benefits claimed in the report become a net cost of $1.5 billion to
$3.8 billion over 10 years.
The Revenue Stream estimate came from a 2002
Rand report, and from numbers developed by the Northwest Energy
Coalition. The panel said it was unclear whether the report's estimate
of replacement power included transmission and ancillary costs, which
would likely be even higher than for combined-cycle combustion.
In a Feb. 28 press release, Steve Weiss, senior policy
associate for the NW Energy Coalition, said the IEAB made a "major
error" by assuming the hydropower would be replaced by
fossil-fueled gas turbines, "something that never would be
considered given the high cost of natural gas relative to efficiency and
wind power."
In a footnote to Revenue Stream, the authors
said updated information from a 2000 NWEC report called "Going With
the Flow" was used to develop the upper limit of their estimate of
the cost to replace power from the dams, with more that 80 percent
coming from conservation, and about 18 percent from wind power.
But the IEAB pointed to a 2002 review of the earlier
RAND report by NPPC staffer Terry Morlan that found conservation and
renewables would not reduce the cost below that of combined cycle
generation. The board said that upper bound in Revenue Stream
"appears to incorporate" some of the same conservation cost
assumptions from the RAND report.
But Weiss neglected to mention that wind power is
notoriously unreliable and generally needs some type of expensive backup
to ensure reliability. During last year's heat wave in July, regional
wind power facilities barely generated 12-15 percent of their capacity
simply because there was no wind.
BPA said the lower Snake dams not only produce more
than 1,000 average megawatts a year, up to 15 percent of its total power
supply, but they are also "helpful to fill in behind intermittent
sources of power such as wind and provide the region with electricity
reserves that help maintain overall system reliability."
