LARGE DAMS: Learning from the Past, Looking at the Future
114 Hydropower: A New Business or an Obsolete Industry?
Divided responsibilities. The major parties
involved in any hydro project are the owning utility,
its government, the engineers, the financiers and the
contractors. None of these parties feels responsible
for the eventual outcome of the projects. The owners
hire engineers to do site investigation. At this point
the owner is politically committed to the site and may
well have the financing lined up. The owner is usual-
ly in a hurry and reluctant to spend too much on site
investigation. In any case, bad news would be unwel-
come at this point in time. The engineers have a
vested interest in keeping the project going in order
to obtain supervision and other work. The contrac-
tors are doing what they are told—changes to orders
are welcome and “surprises” are an opportunity to
claim more money. The larger the cost overruns, the
bigger the engineering firms’ commissions. The
financiers do not depend on the project to be repaid
but rather on the government; they have their gov-
ernment guarantees and will get paid whether the
project is successful or not. Attempts to control costs
through turnkey contracts do not work where
responsibilities are so divided.
Lack of risk management. Project risks, particu-
larly market and financial risks, are seldom adequate-
ly quantified, and risk mitigation strategies primitive
at best. The risk of cost overruns, for example, is
quantified in terms of plus or minus 10 percent or 20
percent on overall costs. In practice it is not unusual
to find cost overruns of 50 percent to 80 percent.
The cost of delays, an almost inevitable consequence
of the financing mechanisms, receives only cursory
analysis. Most projects have a significant proportion
of their costs covered through allocations from the
government budget, and the assumption is made that
governments will make their contributions in a timely
manner. This seldom happens and, as a conse-
quence, is a major risk associated with any hydro pro-
ject. Yacereta in Argentina and Porto Primavera in
Brazil are examples of huge infrastructures partially
in place with completion delayed by lack of funds. If
these risks had been reasonably estimated, these pro-
jects would not have gone forward.
In a world in which hydropower has to compete
with alternative technologies for private capital, the
institutional structure described above is not compati-
ble. No private investor or lender is prepared to risk
capital in an industry unable to get its act together.
Private capital will insist on all risks being quantified
and assigned to responsible parties.
Engineers who do the site development work will
have to be accountable for the results, and a failure to
detect underground problems, for example, will
result in real penalties for the firm. In a recent bid
for an operations and maintenance contract for a pri-
vate power plant, the winning firm was required to
put up a $75 million security bond. For every day the
plant fails to produce power as specified in the con-
tract, the firm will have to compensate the owners for
lost revenues.
Turnkey contracts are no longer flexible negotiat-
ing instruments to be adjusted over the life of the
project. Governments may be willing to pick up the
costs of failure to produce on time, at cost and with
performance as specified, but private parties risking
their own capital will not. Private lenders will not be
prepared to risk their capital on projects dependent
on promises of money from public budgets. They
will insist the government disburses its share before
they put in a penny. Neither will they advance funds
before a clear resolution of land, resettlement and
environmental issues.
3. MANAGING RISK
Engineers tend to focus on technical risks. In
practice, with private power projects, the technical
risks have seldom proved to be a problem. With
very few exceptions, recent privately financed and
built fossil fuel plants have arrived early, usually
below cost and with better-than-specified perfor-
mance. Although hydro presents some unique tech-
nical risks, I am confident that, given the right incen-
tives, the engineers can solve the technical issues. It
is other risks the industry needs to learn to manage
better.
Market risk. In the world of government procure-
ment, all market risks have been assumed by govern-
ment. It is assumed there will be enough customers
willing to buy the output of the plant at prices that
cover costs and perhaps allow room for some profit.
In the case of privately built and owned plants, it is
common to have a long-term power purchase agree-
ment with the utility and, in the developing world,
usually with some form of government guarantee.
The basic assumption behind these contracts is that
