A Dam Revival, Despite Risks
Private Funding Brings a Boom in Hydropower, With High Costs
By ERICA GIES, New York Times, NOV. 19, 2014
While some dams in the United States and Europe are being
decommissioned, a dam-building boom is underway in developing countries.
It is a shift from the 1990s, when amid concerns about environmental
impacts and displaced people, multilateral lenders like the World Bank
backed away from large hydroelectric power projects.
World hydropower production will grow from 4,000 terawatt hours now -
about the annual power output of the United States - to 4,670 terawatt
hours in 2020, according to Maria van der Hoeven, executive director of
the International Energy Agency, in Paris. The Intergovernmental Panel
on Climate Change predicts that hydropower generation will double in
China between 2008 and 2035, and triple in India and Africa.
The World Bank and other international lenders were the most important
financiers of large dams before the '90s lull. But although the World
Bank has in recent years increased its investment in hydropower from a
low of just a few million dollars in 1999 to about $1.8 billion in 2014,
it still funds only 2 percent of hydropower project investment today.
Picking up the slack are national development banks from emerging
countries such as China, Brazil, Thailand, and India, and private
investors. Public-private partnerships are on the rise, generally with
the support of regional development banks.
"Who benefits from these infrastructure projects?" asked Jason Rainey,
executive director of the anti-dam group International Rivers, in
Some well-documented answers: The Xayaburi Dam in Laos will sell power
to Thailand, while threatening the subsistence livelihoods of people who
have long lived along the Mekong River; the Inga 3 dam in the Democratic
Republic of Congo will sell power to mining companies and to South
Africa, rather than to the 96 percent of Congolese who lack access to
A 2012 report from International Rivers found that Chinese companies or
financiers were involved in 308 dam projects in 70 different countries,
many in Southeast Asia, but also some in Africa, Latin America and
Pakistan. Aside from supplying electricity to investing countries,
projects can also offer a type of vertical integration to power funders'
industrial projects, such as mining or smelting. "China isn't the only
one working this model," Mr. Rainey said: "The Brazilian Development
Bank has financed more dam projects in Latin America than the
Inter-American Development Bank. India is investing in hydropower in
Nepal and Bhutan."
Nancy Alexander, director of the Economic Governance Program for the
Heinrich Boell Foundation, a public policy institute in Berlin, said she
attributed this trend partly to a Group of 20 initiative that
prioritized infrastructure investment as a path to economic stability.
The initiative encourages joint financing by multilateral development
banks and other sources. A World Bank report on hydropower this year
said that the bank now "typically acts as a 'convener,' bringing other
financiers to the table." It said that over the past five years, the
World Bank Group had funded about half of the costs of projects that it
financed, with the balance coming from host country governments, the
private sector and other development banks.
Ms. Alexander said the problem with this model is that it "derisks"
mega-projects for the private sector and draws in institutional
investors like pension funds and mutual funds. "Very often this means
privatizing profits and outsourcing risks to the public," she said.
Those risks can be both significant and hidden, she added. Project
backers may cite national security or business confidentiality to avoid
sharing information with the public.
National development banks such as the Brazilian Development Bank, China
Development Bank and the Development Bank of Southern Africa "have
abysmal records in terms of transparency and in terms of social and
environmental safeguards," Ms. Alexander said.
The reduced involvement of global institutions allows countries to
ignore international concerns. Although international backers have
pulled out, for example, public-private funding has permitted Turkey to
go ahead with its Ilisu Dam on the Tigris, defying Unesco's objections
that it would flood Hasankeyf, a town with 10,000 years of history.
Turkish dam projects have also played a role in drying out Iraqi
wetlands downstream and exacerbating tensions in Syria.
Yet, although dam investment is coming from diversified sources,
activist organizations still look to the World Bank to set the standard
for environmental and social protections. At the World Bank's annual
meetings this autumn, 318 civil society organizations from 98 countries
criticized its proposal for a new environmental and social framework,
saying it would weaken existing safeguards. Among other things, they
said, it would undermine the rights of indigenous people and of those
displaced by projects, fail to protect workers or guarantee human rights
and not meaningfully address climate change.
"They have a lot of weasel language that softens and dampens
safeguards," Mr. Rainey said.
Amy Stilwell, a spokeswoman for the World Bank, said the proposal was
just a starting point. A second phase of consultations, including those
with the petitioning groups, will begin soon, with a second draft
expected in 2015, she said.
Part of the reason dams are back in favor, despite ongoing concerns, is
the increasing awareness of climate change and the need for cleaner
energy sources, said Ken Adams, president of the International
Hydropower Association, an industry group based in London. Hydropower
can also balance the electricity load and store energy to support
intermittent renewable energy sources, such as wind and solar, he said.
The Intergovernmental Panel on Climate Change supports hydropower to
slow climate change, calling it a "proven, mature, predictable
technology," in a 2011 report.
Hydropower's reputation for low emissions, however, has come under
scientific scrutiny in recent years. Reservoirs behind dams flood
vegetation, which decays, releasing methane and soil carbon. A 2012
study, in the journal Nature Climate Change, concluded that "emissions
from tropical hydropower are often underestimated and can exceed those
of fossil fuel for decades."
The study emphasized that the effect is more pronounced in tropical
ecosystems. Yet hydropower is typically presumed to be emission-free,
Mr. Rainey said. "There is no mechanism within dam sanctioning
processes, or any of the funding models, that methane emissions be
monitored in dam projects," he said, adding that even carbon market
instruments such as the Clean Development Mechanism help to fund large
dams without considering their carbon footprints.
Mr. Adams said his association's voluntary standards could offer a
solution. Its Hydropower Sustainability Assessment Protocol, drafted
with input from various stakeholders, including the World Bank, provides
a framework for hydropower developers to monitor and benchmark their
projects. William Rex, a hydropower specialist at the World Bank said:
"We see it as a really useful tool."
Mr. Adams said his association would like to see financial institutions
encourage borrowers to use it. "Any energy source is going to have its
good side and downside," said Mr. Adams. "But I believe that if done
intelligently and appropriately, the downsides to hydro projects can be
