The Coal Pile
About 1,199 new coal-fired facilities (as defined by the World Research Institute)—a total installed capacity of 1,401 GW—were being proposed globally as of July 2012, spread across 59 countries. China and India account for about 76% of the proposed coal power capacities, and Chinese and Indian companies lead the pack of 483 firms proposing to build the new plants. These are the 10 countries leading the global coal power boom. Sources: World Research Institute, International Energy Agency

Progress in electronics
and information technology has created incentives to replace traditional
analog instrumentation and control (I&C) systems in nuclear power
plants with digital I&C systems, or systems based on computers and
microprocessors. About 40% of the world’s operating reactors have been
modernized to include at least some digital I&C systems, according
to the International Atomic Energy Agency. From another perspective, 90%
of all digital I&C installations have been modernization projects
at
existing reactors; 10% have been at new reactors. POWER looks at nuclear
plants around the world that are leading the digital revolution.
Stretching the Pipeline
World natural gas demand
climbed to 3,361 billion cubic meters (bcm) in 2011, increasing in all
regions, with the exception of Europe. Countries with the largest
volumetric gains in consumption were China (21.5%), Saudi Arabia
(13.2%), and Japan
(11.6%). North America, led by the U.S. (2.4%), became the
second-largest consumer market after Asia-Pacific. In 2011, gas demand
growth was accompanied by expanding international pipeline flows (which
have increased about 3.7% per year since 2009) and inter-regional
transport capacity. Here are
some of the longest pipelines recently built as well as noteworthy ones
in the pipeline.
Subsidy Tug-of-War
Government decisions to
subsidize renewable power to increase its capacity or environmental and
security reasons have spurred investments but also increased
cross-border tensions. Increasingly, legal actions that seek to settle
international trade
disputes allege unfair subsidization. Here are some of the major ongoing
cases.
Critical Energy Agendas
The global energy sector
will need to invest half of current world gross domestic product over
the next two decades in order to address a number of critical issues and
expand and adapt the energy infrastructure, the London-based World
Energy Council
(WEC) says in its recently released World Energy Issues Monitor. Here
are the most pressing issues affecting three regions. The top-left
quadrant of each regional map represents issues of high uncertainty and
high impact; the top-right quadrant covers issues of high impact but of
higher
certainty—things that keep energy leaders busy. The bottom-left quadrant
represents issues of perceived lesser importance (or those that are
poorly understood), and the bottomright quadrant presents issues of low
impact and high certainty. Bubbles are proportional to the urgency of an
issue.
Power Accident Impacts
The history of electric
power has been stained by several devastating incidents triggered by
natural hazards, technological failures, malicious actions, and human
error. Here POWER surveys some of the world’s most devastating or costly
incidents.
Parched
Water scarcity as it
relates to energy use is becoming a major concern. Cooling water
accounts for more than 50% of national water withdrawals in several
developed countries (Eurostat 2010), and it is becoming more important
as developing countries
become more energy-intensive. At a river basin level, dry periods have
triggered rolling blackouts, and not just because hydropower plants are
forced to operate at dangerously low levels. POWER takes a look at more
recent droughtrelated outages around the world.
Workforce Woes
The U.S. power sector is
grappling with a rapidly morphing energy mix and reliability concerns
made more urgent by a predicted 28% increase in power consumption
through 2040. Another complication: the sector’s workforce, like its
assets, is
maturing and shrinking. As more entities look into smart grids and put
renewables and storage options online, more uncertainty is presented by
the increased complexity of varying future workforce needs.
Fuel Balance
In 2012, as the massive
development of unconventional gas production continued in the U.S.,
domestic natural gas prices plunged and a swathe of American power
utilities realized a coal-to-gas switch in favor of the cheaper fuel.
But Europe, where
natural gas is still largely linked to the price of oil and remains
costly, saw countervailing effects: As coal volumes surged (from
increased U.S. exports), and the carbon trading system stagnated, coal
has become the power generation fuel of choice in several European Union
(EU) countries at the
expense of natural gas.
Emissions Enforcement
Since 1999 when the
Environmental Protection Agency (EPA) initiated what is perhaps its most
comprehensive enforcement initiative, it has issued complaints, notices
of violations, and administrative orders for hundreds of coal units
under the Clean
Air Act’s New Source Review (NSR) program. The agency alleges that these
units failed to obtain a Prevention of Significant Deterioration (PSD)
permit to install Best Available Control Technology (BACT) prior to
“modifying” the units in a manner that increased emissions of air
pollutants. More than 70% of the nation’s coal-fired fleet is under
investigation for NSR violations.
Reactor Outages
At the end of 2012, 436
reactors were connected to the grid, according to the International
Atomic Energy Agency’s (IAEA’s) PRIS database. Operating reactors had an
average 2,239 full outage hours per reactor in 2012; about 15% of that
time represented unplanned outages, caused by a variety of factors.

reactor; GCR = gas-cooled reactor; LWGR = light water cooled graphite
moderated reactor; PHWR = pressurized heavy water reactor; PWR =
pressurized water
reactor.
Capturing Carbon
Of 64 large-scale
integrated projects to capture and store more than 25 million tonnes per
year of carbon dioxide (CO2) that are already active or planned
worldwide, only 29 are dedicated to the power sector. Carbon capture and
storage (CCS) projects
are operational in the gas processing and high-purity industries, but
not in the power generation sector. The pace of CCS development remains
well below the level for CCS to make a substantial contribution to
climate change mitigation, says the Global CCS Institute. Its cause: not
technical
uncertainties but insufficient policy support “exacerbated by poor
public understanding of the technology.”
Gas Taxes
After years of political
wrangling, coal-rich Australia in November passed legislation that will
require the nation’s top 500 polluters, starting in July 2012, to pay a
tax at a fixed price of A$23 (US$23.50) per ton of carbon. The tax
increases 2.5% annually until 2015, when an emissions trading program
will begin. With the Kyoto Treaty set to expire at the end of this year,
several governments have in recent years implemented similar measures
on manufacturers and power companies. Others—like South Africa, China,
South Korea,
Taiwan, and France—have proposed or are considering taxes on carbon
emissions. See the web exclusive story associated with this issue at www.powermag.com for an in-depth look at the world’s carbon taxes.
DOE Loan Guarantees
Of the $35.9 billion in
loan guarantees awarded by the U.S. Department of Energy (DOE) since
2009, roughly $26.5 billion have financed nuclear and renewable power
projects across the nation through the Section 1703 and 1705 loan
guarantee programs.
Section 1703 of the 2005 Energy Policy Act’s (EPAct’s) Title XVII is
meant to support clean energy technologies (including nuclear, advanced
fossil energy coal, carbon sequestration, and projects promoting
industrial energy efficiency) that are unable to obtain conventional
private
financing due to high technology risks. The American Recovery and
Reinvestment Act of 2009 amended the Loan Guarantee Programs by adding
Section 1705 to EPAct. That program—which ended Sept. 30,
2011—authorized loan guarantees for renewable energy and transmission
projects. Here’s a look
at how these loan guarantee programs have been rainmakers for nuclear
and solar generation in particular.
Dammed Dams
New coal and nuclear
power plants aren’t the only ones facing opposition. Several countries
that are struggling to alleviate chronic power shortages are facing
hurdles as they attempt to build new hydropower plants. Here are some
massive
projects riddled with setbacks caused by everything from social and
environmental protests to funding collapses.
Nuclear Aftershocks
In the year following
the Fukushima accident in Japan, the nuclear sector has seen several
setbacks as well as major milestones. Background image from video of the
Daiichi plant in the early morning hours of March 12.
Coal Demand Surges
Patterns of coal trade
have been shifting in recent years as demand surges in Asian countries.
Whereas Japan and the European Union (EU) have long been the world’s
largest hard coal importers, China and India are now emerging as top
importers.
This surge has shifted the center of gravity in international coal trade
to the Pacific Basin market, as estimates from the International Energy
Agency (IEA) show. All projections are per the IEA’s New Policies
Scenario, which assumes cautious implementation of policy commitments
and plans
announced by countries around the world. Note: All figures in million
tonnes of coal equivalent.
A Shale Gas Revolution
Large circles represent
technical reserves and small circles represent potential reserves of
shale gas, both in trillion cubic feet. Bars on the right represent each
region’s existing natural gas–fired generation in 2008 and the amount
projected for 2035 in TWh.
Infrastructure
Aging infrastructure
ranks at the top of the U.S. electric power sector’s concerns, flanked
by the exorbitant investment needed to keep the system in good repair.
Mercury Regulations Rising
Countries with the Highest Mercury Emissions from Fossil Fuel Combustion for Power and Heating
A Big Switch
The widespread
transition from coal to natural gas for new generation is exemplified by
the morphing fleets of some of the biggest U.S. generators.
Regulation Road
The road traveled by
much of the U.S. power sector over the past five years has been a long
and winding one, marked by new regulations from the Environmental
Protection Agency (EPA) and key legal developments. More regulations are
expected over the
next five years.
Advanced Fission
Reactor technology has
been developed and improved over more than five decades. The
first-generation reactors developed in the 1950s and ‘60s were
superseded by a second generation, typified by existing nuclear fleets
in the U.S., France, and
elsewhere. Here’s a look at how technology is advancing around the
world.
And so much more!
