Inner
Mongolia’s rivers are feeding China’s coal industry, turning
grasslands into desert. In India, thousands of farmers have protested
diverting water to coal- fired power plants, some committing suicide.
The
struggle to control the world’s water is intensifying around energy
supply. China and India alone plan to build $720 billion of
coal-burning plants in two decades, more than twice today’s total
power capacity in the U.S., International Energy Agency data show.
Water will be boiled away in the new steam turbines to make
electricity and flush coal residue at utilities from China Shenhua
Energy Co. (1088) to India’s Tata Power Co. (TPWR) that are
favoring coal over nuclear because it’s cheaper.
With
China set to vaporize water equal to what flows over Niagara Falls
each year, and India’s industrial water demand growing at twice the
pace of agricultural or municipal use, Asia’s most populous nations
will have to reconsider energy projects to avoid conflict between
cities, farmers and industry.
“You’re
going to have a huge issue with the competition between water, energy
and food,” said Vineet Mittal, managing director of Welspun Energy
Ltd., the utility unit of Leon Black’s Apollo Global Management
LLC-backed Welspun Group.
“Water is something everyone should be
probing every chief executive about,” he said in an interview.
Investors
have driven up the 49-member S&P Global Water Index (SPGTAQD)
about 96 percent from its low point after the 2008 financial crisis.
That beat the 88 percent gain in the period by the 1,625-stock the
MSCI World Index, a global benchmark, and trailed the Dow Jones
Industrial Average’s 101 percent increase.
Investor
Risk
“Power
is a very good example of the risk investors can potentially face,”
Giulio Boccaletti, a partner heading McKinsey’s water resource
economics practice, said in an Aug. 30 interview. “A problem with
water can leave you with a stranded asset.”
China
and India account for than 60 percent of the world’s coal-fired
power plants on the drawing boards by 2035, capable of producing
about 805 gigawatts. China’s alone will consume 82 billion cubic
meters of water a year by 2030, second only to the nation’s
farmers, McKinsey & Co. forecast.
More
than half of existing and planned power plants by the biggest
publicly traded companies in India and Southeast Asia are in areas
likely to face water shortages, according to the World Resources
Institute in Washington, which maps water risks for industries.
Little data is collected by companies or their investors on what that
means for projects with a 40-year lifespan, the U.S.-based researcher
said in a report.
’Peak
Water’
India’s
power plants may be most vulnerable, the institute concluded after
mapping more than 150 existing and planned projects in India and
Southeast Asia. It found that 73 percent of capacity owned by three
utilities -- NTPC Ltd. (NTPC), Tata Power, and Reliance Anil
Dhirubhai Ambani Group Ltd.’s power units --is located in
water-scarce or stressed areas. Overall, 74 gigawatts, more than half
of India and Southeast Asia’s existing and planned capacity, face
similar threats.
NTPC
said in an e-mail response that its projects require a water
commitment from state authorities for the full lifetime of the plant
before they go ahead. It’s also using saltwater desalination at
coastal plants to minimize fresh water usage.
Tata
Power declined to comment. Reliance Power Ltd. (RPWR) didn’t
respond to two e-mails and telephone calls seeking comment.
“The
world has already hit ’peak water,’” says Simon Powell, head of
Asian oil and gas research at CLSA Ltd. in Hong Kong. Demand is
growing against a finite supply of fresh water that’s shrinking due
to pollution and climate change, he said.
Global
water demand may have already outstripped supply in 2010. The world’s
freshwater requirement in 2010 was estimated at 4.5 trillion cubic
meters compared to an accessible supply of 4.2 trillion cubic meters,
according to McKinsey & Co.
Water
Assumptions
Coal
is currently running more than 40 percent of the planet’s
electricity generation plants, which consume on average three times
as much water as natural gas-fired stations per unit of power
produced, according to U.S. Department of Energy data. Nuclear plants
use even more water than coal units.
Beside
needing water to produce steam, it’s also used in condensing and to
process waste deposited in ponds. Water is used in coal mining to
remove impurities and transport the fuel through pipelines as slurry.
Some
of the water can be recycled or discharged back to its source.
However, a shortage can shut a plant or force it to compete for
farming and drinking water.
Utilities
“assume the water is there,” Peter C. Evans, director for global
strategy and planning at General Electric Co. (GE), the biggest maker
of power-plant turbines, told a conference in June in Tokyo. “They
actually will not be able to build as many coal plants as the
projections suggest.”
Ground
Zero
Grasslands
drying up in Inner Mongolia is caused by coal mines and power plants
taking from rivers, said an Aug. 14 study by China’s Institute of
Geographical Sciences and Natural Resources Research commissioned by
Greenpeace. The region holds less than 2 percent of China’s water
and by 2015 will host about triple the European Union’s coal-fired
capacity, it said.
Ground
zero in India’s fight for water may be along the 560-mile stretch
of the Mahanadi river in the coal-rich states of Chhattisgarh and
Odisha, where paper mills, steel plants and mines mostly powered by
coal plants flank the river’s banks.
The
state governments have signed agreements for at least 49 coal power
plants with a combined 57.5 gigawatts of capacity, according to Ravi
Shekhar, a power industry consultant at New Delhi-based Infraline
Energy Research and Information Services. That’s more than Japan’s
coal-fired plant capacity, according to IEA figures.
“The
allocation of water for these industries is irrational,” says
Infraline analyst Simran Jeet Singh. “They allocate without any
planning.”
Thousands
Protest
Farmers
in India have blocked highways and railway lines, sometimes
committing suicide, to protest coal plants under construction that
they fear will drain rivers and choke off irrigation water.
On
Aug. 27, three thousand villagers protested against a 1,320-megawatt
coal plant planned at Pitamahul, one of many demonstrations along the
Mahanadi, says Ranjan Panda, an activist with Water Initiatives
Odisha. Irrigation projects are stalling and villages are being
displaced, he said.
“This
river is a lifeline and every stretch is either already being used by
industry or has been committed,” he says.
Companies
building coal plants and their lenders say they’re taking
precautions to ensure water supply. When projects are planned, rights
to fuel and water are among the permits obtained before a project is
approved.
“When
someone comes to me with a project proposal, I will make sure that
the water is available, adequate water,” Satnam Singh, chairman of
Power Finance Corp. (POWF), India’s largest lender to electricity
utilities, said in a June interview. “Water is not going to become
zero.”
Straining
Rivers
Yet
there are signs authorities are granting more water rights than
rivers can sustain.
In
April 2010, Maharashtra State Power Generation Co. shut down 90
percent of its 2,340-megawatt power station in Chandrapur about 520
miles east of Mumbai after low rainfall caused water levels to
plummet at the Erai dam, according to a letter sent by the utility to
the electricity regulator.
The
same plant is now in the midst of a 1,000-megawatt expansion and
another 7,000 megawatts of coal-fired plants are planned in the area,
according to Infraline’s Singh.
In
2009, Beijing shut 49 factories and moved some power plants and steel
factories to the coast because of a lack of water, Maxime Serrano
Bardisa, water analyst for Bloomberg Energy Finance in London said in
a July 2 interview.
In
April, India’s Oil & Natural Gas Corp. closed an oil refinery,
another water-intensive industry, when levels dropped in the
Nethravathi river in southern Karnataka state.
Lack
of Fuel
The
Indian government also has a track record of reneging on its promises
on another essential supply: fuel. India’s coal power industry has
delayed or canceled about 1.9 trillion rupees ($34 billion) in
projects because of production shortfalls at state-controlled Coal
India Ltd. (COAL) and a rail system that can’t move enough cargo,
according to data from the Association of Power Producers.
CLP
Holdings Ltd. (2), Hong Kong’s biggest electricity supplier, passed
on an opportunity to build a new coal plant in Odisha state because
of concerns about water, Naveen Munjal, director of business
development, said in a June interview. CLP was stranded this year
with a 1,320-megawatt coal plant in Haryana that’s “dead cold”
for lack of fuel supplies, he said.....
