Climate change is causing an increase in many types of extreme weather. To date, these kinds of severe weather are among the leading causes of large-scale power outages in the United States.
This document discusses the health risks of biomass combustion and argues that current regulations do not adequately protect human health. It presents data showing biomass combustion emits more particulate matter and other pollutants per unit of energy than coal. These pollutants are linked to various diseases, especially in children. While biomass plants may obtain necessary permits, the document argues permits do not guarantee safety as regulations allow harmful pollution. It also notes the biomass industry receives substantial government subsidies.
Petron Group LLP predicts Energy and fuel prices in the United StatesPetron Group LLP
The document discusses trends in US renewable energy and electricity prices. It notes that in 2014, 67% of US electricity came from fossil fuels like coal and natural gas, but renewable sources like wind and solar are increasing. Electricity prices have risen 42% in the last decade and are projected to continue increasing due to coal plant closures, natural gas price volatility, renewable energy mandates, and other factors. Power outages could become more common as the grid loses capacity and becomes more fragile.

The document discusses public opinion and politics around climate change in the United States. It finds that while a majority of Americans believe climate change is occurring, the percentage of those who believe it is not happening has risen. It also breaks down the public into categories based on their level of belief and concern about climate change. The document then covers challenges to EPA regulations aimed at reducing power sector emissions and potential impacts to electric grid reliability if compliance timelines are not extended. It discusses costs and challenges associated with renewable energy integration and the benefits of market-based cap-and-trade programs to reduce emissions more cost-effectively.
The document is a policy memorandum from staffer Lyle Birkey to Congressman George Miller regarding an upcoming vote on blocking the EPA's regulation of greenhouse gas emissions. The memorandum recommends voting against the block for three reasons: (1) the costs of climate change from increased extreme weather will rise significantly if unchecked; (2) EPA regulation of greenhouse gases under the Clean Air Act will have initial costs but reduce costs over time as cleaner technologies are adopted; and (3) EPA regulation can boost the economy through job creation and making the U.S. more globally competitive in green industries.
Sierra Club Petition to Federal Trade Commission re Atlantic Coast Pipeline P...Marcellus Drilling News
The Sierra Club letter expresses concerns about potential antitrust violations by utility partners in the proposed Atlantic Coast Pipeline project. Specifically, it argues the utilities may use their monopoly power and captive customer bases to ensure profits for the pipeline, which could result in consumers paying higher costs for unnecessary infrastructure and exclude competition from renewable energy. The letter provides details supporting claims that the pipeline is not needed due to risks of overcapacity and natural gas supply uncertainty. It asserts the utilities' involvement distorts electricity planning and places consumers at risk.

This document provides an overview and analysis of issues related to wind power in the United States from Energy Ventures Analysis Inc. It summarizes that in 2006, wind power accounted for only 0.66% of US electricity generation and 70% of existing wind power capacity is concentrated in 7 states. Wind generation has grown due to state renewable portfolio standards requiring certain amounts of renewable energy. However, wind power faces challenges of being an intermittent and relatively high-cost source of energy that requires significant subsidies to be cost competitive. The document also analyzes wind project siting issues such as the large land needs and potential impacts on local property values and wildlife.

As in previous years, the report is based on the annual Global Risks Perception Survey, completed by almost 900
members of the World Economic Forum’s global multistakeholder community. This year’s report introduces a new distinction between risks and trends, which allows the highlighting of trends as an enlarged solution space to many possible risks.
The 2015 edition of the Global Risks report completes a decade of highlighting the most significant long-term risks worldwide, drawing on the perspectives of experts and global decision-makers. Over that time, analysis has moved from risk identification to thinking through risk interconnections and the potentially cascading effects that result. Taking this effort one step further, this year’s report underscores potential causes as well as solutions to global risks. Not only do we set out a view on 28 global risks in the report’s traditional categories (economic, environmental, societal, geopolitical and technological) but also we consider the drivers of those risks in the form of 13 trends. In addition, we have selected initiatives for addressing significant challenges, which we hope will inspire collaboration among business, government and civil society communities.

This study analyzes the impacts of increased cycling of fossil fuel power plants induced by high levels of wind and solar power on the electric grid. It finds that up to 33% wind and solar penetration would increase annual cycling costs for fossil plants by $35-157 million in the Western Interconnection grid. From the perspective of an average fossil plant, cycling costs would increase by $0.47-1.28/MWh compared to total fuel and operating costs of $27-28/MWh. However, 33% wind and solar would displace about $7 billion in annual fuel costs for the system. The study also finds that up to 33% wind and solar reduces carbon and other emissions by 14-34% despite some
The document summarizes reports on major power blackouts that occurred in India on July 30th and 31st, 2012. It provides an overview of the Indian power grid system and describes the sequence of events that led to each blackout. For the July 30th blackout, key factors included the planned shutdown of a transmission line which overloaded other lines, and unscheduled power flows that caused disturbances. The July 31st blackout affected a wider region due to the tripping of another transmission line. The report lists technical and policy recommendations from investigations to prevent future blackouts, such as strengthening transmission corridors and monitoring systems. It also discusses the need for smart grid technologies going forward.
The document discusses blackouts, which refer to a total loss of power to an area. Major blackouts in recent years have affected millions of people. Blackouts can last from minutes to weeks depending on their cause and the electrical network configuration. They are usually caused by a cascade of failures beginning with an initial fault, such as a power plant tripping offline or a transmission line failure overloading other systems. Better monitoring, improved infrastructure like superconducting cables, and a smart grid can help reduce risks of widespread blackouts.
1) Voltage collapse is a major cause of recent blackouts due to increased reliance on remote generation and lack of transmission expansion. As transmission lines trip, reactive power losses increase, reducing voltage.
2) Generators provide reactive power (VARs) to support system voltage through their automatic voltage regulators (AVRs). During low voltage events, AVRs and generator protection systems may not be able to maintain stable operation.
3) Undervoltage load shedding is used to prevent total system collapse by automatically removing certain loads if voltage drops below a threshold for a set time period. This helps restore the balance between generation and load.

Recent climate volatility has increased the frequency of extreme weather events like flooding, droughts, and abnormal temperatures. As populations and infrastructure grow, society faces greater exposure and vulnerability to these hazards. Planning and adaptation are needed to increase resiliency against weather volatility and its impacts.
SE Weather Volatility White Paper - 2015Ron Sznaider
Recent climate volatility has increased the frequency of extreme weather events like flooding and abnormal temperatures. As populations grow and infrastructure expands, society faces increased exposure and vulnerability to these hazards. Preparing for and adapting to a more volatile climate requires risk planning and actions to increase resiliency. Some weather events that have become more common due to recent climate trends include excessive rainfall and flooding, extended periods of abnormal hot or cold temperatures, and drought, which stresses water supplies and increases wildfire risks. Planning for these high-impact weather hazards can help limit disruptions.
Smart Grid Electricity System Planning Post-Superstorm SandyRyan Collins
The document discusses focus groups conducted with energy stakeholders in New York, Massachusetts, and Vermont after Superstorm Sandy to examine how the storm impacted perspectives on climate change adaptation and mitigation. The analysis found that discussions in the most impacted state of New York focused most heavily on climate adaptation, while conversations in the least impacted state of Vermont focused more on mitigation. Massachusetts stakeholders discussed adaptation and mitigation more equally. The severity of a climate event's impacts on a location influenced whether stakeholders prioritized adapting energy systems to future climate risks or transitioning to low-carbon energy as a form of mitigation.
Aging Power Infrastucture in the US: Towards a Solutionpacificcresttrans
According to the United States Energy Department. the demand for electricity in the US is growing at the rate of about 1% a year, with the pace likely to increase over the next few years. Other estimates put the increase at 6% or more per year, thanks to the population growth rate and the burgeoning numbers of electric/electronic devices now considered essential to people's lifestyles.
The aging U.S. energy infrastructure received a grade of D+ due to outdated infrastructure contributing to power failures. An estimated $1.5 trillion investment is needed by 2030 to modernize the electric grid. Climate change has also increased storms and events causing more outages, requiring infrastructure to be hardened. A shortage of energy sector workers is also projected due to retirements, requiring new training and skills. Sustainable funding sources must be identified to invest in improvements and protect against worsening climate conditions.

Interrelation between Climate Change and Lightning and its Impacts on Power S...IOSR Journals
Climate change is expected to increase lightning activity, posing risks to the power sector. A warmer climate could lead to fewer but more intense thunderstorms, increasing flash floods, wildfires, and damage to power infrastructure from lightning strikes. This would likely cause more blackouts. As lightning activity rises with climate change, utilities must invest in strategies to adapt operations and strengthen transmission infrastructure to manage these new risks. Developing accurate climate and lightning databases could help utilities better forecast hazards and mitigate impacts on the power grid.
Overcoming Obstacles to High Penetration Renewable Energy in the United StatesBruce Cohen
This document provides an overview of renewable energy in the United States. It discusses the various state and regional programs promoting renewable energy development, including 29 states with Renewable Portfolio Standards and 26 with Energy Efficiency Standards. It also outlines major federal initiatives like the EPA's Clean Power Plan aimed at reducing greenhouse gas emissions from power plants. While progress has been made, the document notes that critical market and regulatory reforms will still be needed to significantly alter the country's energy profile and meet global climate commitments. Barriers to reform are also examined along with examples of how some jurisdictions are attempting to overcome obstacles to transition to higher renewable energy.
This document discusses how climate change poses an existential threat and how information and communication technologies (ICT) and networks can help societies adapt and survive. Rapid warming is already causing severe impacts like droughts and flooding that will disrupt energy systems and infrastructure. To adapt, networks must be designed to operate on renewable energy sources like wind and solar, even relocating facilities to remote locations with clean power. This represents an opportunity for innovation in areas like follow-the-sun computing across data centers. National research and education networks (NRENs) can act as cloud brokers to facilitate such distributed computing on green infrastructure.
Impacts of climate change to Critical Infrastructureeu-circle
This document provides an outline for a course on the impacts of climate change on critical infrastructure. It begins by defining critical infrastructure and describing key sectors like energy, water, transportation, and chemicals. It then discusses how infrastructure systems are interconnected and vulnerable to failures that can cascade between sectors. The document outlines several ways that climate change may negatively impact critical infrastructure through increased temperatures, sea level rise, flooding, and other extreme weather events. Specific risks are described for electricity networks, oil and gas facilities, chemical plants, water infrastructure, and transportation assets. The goal of the course is to explain how climate change threatens critical services and economic well-being.

Winter storms can dump several inches of snow, causing flight cancellations, school closures, and disruptions to power and other services. Hurricanes bring strong winds, storm surge, heavy rain, tornadoes, and have caused deaths in the past. Floods are a common occurrence after heavy rain or snow melt, with one catastrophic flooding in 2009 causing over $500 million in property damage. The response plan will include mitigation, preparedness, response and recovery strategies to address these three disasters.
The document discusses the vulnerability of the US electric power grid to electromagnetic pulse (EMP) events and severe space weather, such as solar storms. It notes that EMP and space weather could cause widespread, long-term power outages across the US by damaging transformers and other key infrastructure. Such an event may cost over $1 trillion and require years to fully recover from. The document calls for improvements to situational awareness, protective measures for critical assets, and disaster recovery planning to address this vulnerability.
This report compares nuclear and wind energy as potential options for Texas to invest in as the first step towards transitioning to 100% sustainable energy production by 2050. The report evaluates the two options based on three criteria: environmental impact, economics, and ability for large-scale implementation. With regards to environmental impact, the report finds that wind power produces 87% less CO2 emissions, takes up 48% less land, and consumes 99% less water than nuclear power. For economics, the report finds that wind power facilities cost 20% less to build and run, take 79% less time to develop and construct, and receive much greater investment than nuclear power. Finally, for large-scale implementation potential, the report finds that while
Finding - Climate extremes and their impactsipcc-media
Climate extremes and their impacts were discussed. It was noted that a changing climate leads to changes in extreme weather events, both in terms of frequency and intensity. Extreme events interacting with vulnerable systems can lead to disasters. Various climate indices were presented to quantify extremes such as temperature and precipitation. Projections indicate increases in hot days and heavy precipitation. Managing risks requires understanding vulnerability and exposure as well as implementing measures like early warning systems, infrastructure improvements, and development policies. Adaptation requires addressing local conditions and involves both short-term risk reduction and long-term sustainable solutions.

This document analyzes Australia's exposure to climate change risks for major infrastructure and the country's level of preparation. It finds that infrastructure damage is a leading cost of climate change globally. While Australia is vulnerable due to its climate and coastal population centers, national readiness is patchy. Several infrastructure sectors like electricity and water have begun coordinated climate adaptation efforts, but most sectors are underprepared for impacts like flooding and heatwaves. The report calls for businesses to fully assess climate risks and governments to better integrate climate risk management nationally.

BLACKOUT: EXTREME WEATHER,
CLIMATE CHANGE AND POWER OUTAGES
3. 3 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
SUMMARY
Climate change is causing an increase in many types of extreme weather. Heat waves are hotter,
heavy rain events are heavier, and winter storms have increased in both frequency and intensity.
To date, these kinds of severe weather are among the leading causes of large-scale power outages
in the United States. Climate change will increase the risk of more violent weather and more
frequent damage to our electrical system, affecting hundreds of millions of people, and costing
Americans and the economy tens of billions of dollars each year.
Climate Central’s analysis of 28 years of power outage data, supplied to the federal government
and the North American Electric Reliability Corporation by utilities, shows:
• A tenfold increase in major power outages (those affecting more than 50,000
customer homes or businesses), between the mid-1980s and 2012. Some of the
increase was driven by improved reporting. Yet even since 2003, after stricter
reporting requirements were widely implemented, the average annual number
of weather-related power outages doubled. Non-weather related outages also
increased during that time, but weather caused 80 percent of all outages between
2003-2012.
• Michigan led all states with 71 major weather-related power outages between
2003 and 2012, averaging at least 800,000 customers affected each year during that
decade. Texas ranked second with 57 outages and also averaged more than 800,000
customers affected annually. Ohio was third with 54, followed by Pennsylvania and
Virginia with 52. The number of customers affected could not be estimated for these
three states.
4. 4 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
• 147 million customers lost power, for at least an hour and often far longer, from
weather-related outages since 2003, an average of 15 million customers affected
each year. Currently, there are 145 million customers in the U.S. A customer is a
home or a business, or anyone who receives a bill from a utility, so the number of
people affected by outages is likely much higher, from 300 million to perhaps half a
billion or more over the decade analyzed.
• 59 percent of weather-related outages analyzed were caused by storms and severe
weather; nearly 19 percent by cold weather and ice storms; 18 percent by hurricanes
and tropical storms; 3 percent tornadoes, and 2 percent by a combination of extreme
heat events and wildfires.
Most of these outages come from damage to large transmission lines or substations, as opposed
to the smaller residential distribution network.
Climate change is a threat multiplier. Major weather-related outages cost Americans between
$20 and $55 billion annually according to recent estimates. Lack of preparedness for increasingly
extreme weather puts people, infrastructure and the economy at growing risk. There is broad
agreement with“very high confidence”that climate change-related extreme weather events
damage critical infrastructure, disrupt the food supply, threaten water supplies and increase
mortality worldwide (IPCC 2014).
Even in cases where the link to climate change is not well understood, extreme weather appears
to be becoming more severe, as the case with hurricanes and thunderstorms. While no Category
4 or 5 hurricanes have made U.S. landfall since the mid-1990s, average hurricane strength and the
total number of Category 4 and 5 hurricanes is increasing. And while the trend in the incidence of
severe thunderstorms is unknown due to lack of comprehensive monitoring, insurance companies
are now paying out at least seven times more for thunderstorm damages than in the 1980s.
Climate change is, at most, partially responsible for this recent increase in major power outages,
which is a product of an aging grid serving greater electricity demand, and an increase in storms
and extreme weather events that damage this system. But a warming planet provides more fuel
for increasingly intense and violent storms, heat waves, and wildfires, which in turn will continue
to strain, and too often breach, our highly vulnerable electrical infrastructure.

01. INTRODUCTION
The U.S. electrical system is one of the country’s most critical infrastructure components.
Distributing electricity to homes, businesses, and industry, as well as large sections of the
transportation sector, the bulk power system is a vast and interconnected grid that people depend
on in all parts of their daily lives. The reliability and resiliency of the grid system is consequently
of utmost importance to all Americans. Yet, much of the nation’s power system today looks
remarkably similar to the way it did half a century ago, and it remains vulnerable to large-scale
outages caused by several threats, including cascading power failures, cyber-attacks, and severe
weather.
Several recent studies have highlighted the overall vulnerability of the U.S. electrical grid.1,2
A
2012 Department of Energy (DOE) report on U.S. infrastructure vulnerability showed that beyond
the risk of power loss at individuals’houses (which cause lighting, heating, and air-conditioning
losses), large-scale power outages also pose larger threats to entire communities and business
sectors.3
Water treatment facilities depend on electricity, and extended power outages can
interrupt flow of clean water and solid waste removal. Hospitals can lose power or clean water,
raising health concerns. Power losses often force businesses to close, affecting sales and overall
profitability, and potentially disrupting extended business-to-business supply chains. According
to a 2001 report, the annual costs of U.S. power outages ranged from $100 billion to $164 billion,4
with the majority of the cost associated with indirect consequences of the power loss (like those
described above) rather than the repair of damaged power lines.
The electricity system can be generally divided into four general components: power generation,
high-voltage transmission, local distribution, and the end-use customers (Figure 1). An intricate
power management system connects all four components together. Damage to power generators
(power plants, primarily), high-voltage transmission lines and local power lines, can each threaten
overall power supply to customers, as can an overall shortage of fuel for electricity generation.
Most major power outages and disturbances (those which threaten power to tens of thousands of
customers) are ones that disrupt high-voltage transmission.

7. 7 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
01. INTRODUCTION
Across the country, and particularly in the Midwest and eastern regions, much of the transmission
and distribution network is still above ground, leaving them vulnerable to the effects of severe
weather, including high winds, heavy rain, ice, snow, and electrical storms. Even in areas where
power lines are buried, flooding caused by heavy rains or hurricane-related storm surges can lead
to major power interruptions.
There is a general scientific consensus that climate change will increase some forms of extreme
weather. Increasing concentrations of atmospheric greenhouse gases is already believed to have
increased the frequency and intensity of some severe weather (see Section 4 for more details and
relevant references). To better understand the electricity sector’s vulnerability to future climate
change, this report examines the proportion of reported large-scale power outages that were
caused by severe weather.
8. 8 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
The power outage data used in our analysis was collected from the U.S. Department of Energy’s
(DOE) Office of Electricity Delivery Energy Reliability, via their form OE-417 reports, and from
the North American Electric Reliability Council (NERC).5
NERC data covered the period of 1984-
1999. Typically, only sufficiently large electrical disturbances (or potential disturbances) meet the
reporting criteria for OE-417, but there are a total of 12 possible criteria by which disturbances are
evaluated.6
Most of the major disturbances reported to the DOE or NERC refer to power outages
during which at least 50,000 customers lost power for at least an hour, there was a power supply
interruption of at least 300 megawatts, or the demand for electricity exceeded the supply (load
shedding) by at least 100 megawatts. The majority of these major outages take place during
electricity transmission (damage to major power lines or substations), though some may reflect
outages originating at power plants or during residential distribution.
The form OE-417 is an emergency reporting mechanism, and is not intended to create a historic
record of thoroughly investigated electricity incidents. Because a form OE-417 is filed before the
full scope of the event is understood, and is not updated later (even if a detailed investigation was
conducted), the data provided is an estimate of the incident.
For the purpose of our analysis, we consider only power outages (including blackouts and voltage
losses), fuel supply emergencies, and emergency appeals for reduced electricity usages where
there was a reported number of customers affected or power lost (Box 1). We have not included
reports of vandalism or cyber-attacks where there was no actual power lost or customers how lost
power in our discussion or in our accounting of non-weather related events. Furthermore, we have
excluded heat wave-related appeals for reduced usage from our count of total weather-related
events (or customers) if there were no numbers provided for customers affected or associated
megawatts. We have, however, included a separate count of these heat-related events to give an
idea of the future threat posed by increasing heat waves.

at least an hour, there was a power supply interruption of at least 300
megawatts, or the demand for electricity exceeded the supply by at least
100 megawatts.
Box 1. Definition of power outage used in this report.
9. 9 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
INCREASES IN REPORTED WEATHER-RELATED POWER OUTAGES
Analyzing data from 1984-2012, we found the number of reported weather-related power outages
increased dramatically in the 2000s (Figure 2), a conclusion similar to those found in previous
studies.3,7,8
There were as many as 10 times more large-scale power outages each year in the 2000s
compared to those reported each year in the 1980s and early 1990s.
Since the late 1970s, the U.S. Department of Energy (DOE) has required power utilities to report
large-scale power outages via an Electric Emergency Incident and Disturbance Report (Form
OE-417) to monitor the overall reliability of the nation’s bulk power system. Similarly, the North
American Electric Reliability Corporation (NERC) has collected power outage data since 1984 via
their System Disturbance Reports. Over the years, however, data collection requirements have
changed, as has the way utility reporting is enforced. Some of the increase in the number of
reported power outages since 2000 is likely related to these reporting changes.9
To help eliminate
trends largely related to increased reporting, we are restricting the remainder of our analysis to
DOE data from the 10-year period of 2003-2012.

Focusing on the period of 2003-2012 reveals that both weather-related and non-weather related
power outages have increased in recent years, which is an indication of the growing vulnerability
of the nation’s power system. As illustrated in Figure 1, since 2003, the average number of
weather-related power outages each year has doubled.
Although the proportion of weather-related outages varies from year-to-year, weather-related
outages made up the vast majority of reported incidents on average between 2003-2012. Of the
911 power outages we analyzed, 80 percent of them (726 outages) were weather-related (Figure
3). Moreover, weather-related and non-weather related outages did not consistently increase at
the same rate over this time, which suggests that the increases were not solely a function of the
changes to how these outages are reported.

More than 147 million customers were affected by these weather-related power outages between
2003-2012. While there is no way to identify exactly how many individual people this corresponds
to, because a customer may be defined as a household (which, on average, would have multiple
residents), a commercial business, or even an industrial building, we assume that at least this many
people, if not significantly more, were directly affected by weather-related outages during this
time.
Of all the customers reportedly affected by power outages and warnings of reduced electricity
from 2003-2012, nearly 90 percent of them were due to weather-related incidents. As Figure 4
illustrates, only in 2003 were fewer than 80 percent of the customers affected by weather-related
outages. The 2003 anomaly was related to a single non-weather related event: a massive blackout
across the Northeast caused by cascade of failures at power plants across the region. With the
exception of 2003, there was no year in the past decade where non-weather related power
outages accounted for more than 20 percent of all customers affected, and there were only three
years where non-weather related events caused outages affecting more than 10 percent of all
customers.

WEATHER-RELATED POWER OUTAGES BY REGION
Our analysis demonstrates that while the entire country experiences severe weather that can
interrupt electricity generation and transmission on a large scale, the Midwest, Mid-Atlantic and
Southeastern states appear to be particularly vulnerable (Figure 5). NERC, a non-profit corporation
that promotes reliability of the U.S. bulk power supply system, is divided into eight regional
reliability entities and major outages (and other incidents) can be categorized by their NERC
region (most of Canada and part of Mexico are also included in NERC regions but incidents in
those areas have been excluded in this report). Box 2 defines each of the eight NERC regions.
Of the 911 weather-related outages studied, 64 percent occurred in the RFC and SERC regions.
These regions encompass all states east of the Mississippi River (with the exception of New
England states and Florida), as well as large parts of Illinois, Missouri, Arkansas, and Louisiana.

Western Electricity Coordinating Council (WECC) - includes Arizona, California,
Colorado, Idaho, Nevada, Oregon, Utah, Washington, Wyoming, most of New Mexico and

The concentration of weather-related events in the Midwest and East matches the distribution
of customers affected by these events. About two thirds of customers affected by weather-
induced outages were also in the RFC and SERC regions, although only about 45 percent of
the U.S. population lives within these states. However, the higher population density and older
infrastructure in these eastern states, compared to the rest of the country, likely makes the region
more susceptible to large-scale power outages.
In contrast, the 11 westernmost states comprise 10 percent of outages and 14 percent of
customers affected, even though the region has about 23 percent of the national population.
The top 10 states most affected by weather-related power outages (based on the number of
incidents, not customers) are Michigan, Texas, Ohio, Pennsylvania, Virginia, Maryland, North
Carolina, California, Illinois, and Indiana. Table 1 shows how many events were reported for
each state (and the District of Columbia).10

15. 15 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
03.TRENDS IN WEATHER-RELATED POWER OUTAGES
Because of the interconnected nature of the grid, many electrical utilities often service large
areas that can span several states. Furthermore, some types of extreme weather, including winter
storms, tropical storms and hurricanes, affect large areas and can cause power interruptions in
many states. Consequently, some electrical utilities are particularly prone to weather-related
power outages. Table 2 shows the top 25 power utilities with the most reported outages between
2003-2012. Only six of these 25 utilities are not centered in the RFC and SERC regions. This
ranking reflects how often areas serviced by these utilities are in harm’s way, how large each of
these utilities are, and whether they provide service to mostly urban or rural areas, among other
factors;11
it is not indicative of weaknesses specific to any one utility.
Table 3 highlights the top 25 power utilities with the most customers affected by weather-related
outages from 2003-2012.

03.TRENDS IN WEATHER-RELATED POWER OUTAGES
POWER OUTAGES BY TYPE OF SEVERE WEATHER
When weather-related power outages are reported via Form OE-417, officials must include
a description for the type of weather that caused the disturbance. However, there are no set
criteria for how weather events are described, and in many cases, the causes of outage events
are categorized simply as storms or severe weather. Consequently, for the purpose of our analysis
we have maintained the category storms and severe weather, which herein refers to outages and
disturbances caused by heavy rains, thunderstorms, high winds, lightning, and general severe
weather.
Between 2003-2012, 59 percent of weather-related outages were caused by storms and severe
weather (Figure 6). Nearly 20 percent of weather-related outages were caused by cold weather and
ice storms, and another 18 percent were caused by hurricanes and tropical storms. Only 3 percent
of outages were caused by tornadoes, and 2 percent were caused by a combination of extreme
heat events and wildfires.
In addition to these outages, extreme heat was responsible for 64 restricted power advisories
between 2003-2012. In some cases, extreme heat was likely related to other, uncounted outages,
but due to limitations in the reporting structure, we are unable to confirm that heat was the cause
of the outage. Across the country, extreme heat and heat waves pose a risk of power outages
that is at least double the threat posed by tornadoes (there were 22 major outages caused by
tornadoes from 2003-2012).
Figure 6.Types of severe weather responsible for all weather-related power outages from
2003-2012.
18. 18 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
OBSERVABLE TRENDS OF INCREASING EXTREME WEATHER EVENTS
While some of the increased reports of weather-related power outage since the 1980s stems
from changes in the way these events are reported, there are other risk factors that are likely also
playing a significant role, including a growing population, aging power system infrastructure, and
measurable increases in many extreme weather events.
According the draft of the U.S. National Climate Assessment (full report due for release in April
2014), many types of extreme weather events have become more frequent and intense in
recent decades, in addition to an overall rise in average temperatures and increase in average
precipitation.12
In many cases, there is evidence that these increases are, in part, caused by
increasing concentrations of greenhouse gases in the atmosphere. In a 2011 special report titled
Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation, the
Intergovernmental Panel on Climate Change (IPCC) also reported observed increases in some types
of extreme weather events in North America.13
Since 1990, heavy downpours and flooding have increased in most parts of the country, and
the trend is most dramatic in the Northeast and Midwest.14
Some of this heavy rain is likely to be
associated with high winds and thunderstorm activity. Researchers have found that these regions
have already seen a 30 percent increase in heavy downpours compared to the 1901-1960 average.
And across the country, more of each region’s total precipitation is falling in heavy events. One
study found that the Northeast has experienced a 74 percent increase in the amount of its total
precipitation falling in heavy events, while the Midwest has seen a 45 percent increase and the
Southeast a 26 percent increase (Figure 7).14

19. 19 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
04. EXTREME WEATHER AND CLIMATE CHANGE
Trends in severe thunderstorm activity, which is often associated with strong winds and heavy
precipitation, remain uncertain partly because of challenges in collecting consistent observations
of these types of storm systems. However, a recent study drawing on results from an ensemble of
global climate models demonstrated that rising atmospheric concentrations of greenhouse gases
increases the risk of thunderstorms by adding more heat and water vapor to the atmosphere.15
The risk appears particularly strong in the eastern U.S. Consistent with this finding is the dramatic
increase in average annual insured thunderstorm losses since the 1980s, as reported by Munich
Re.16
Heat waves are also happening more frequently than they were just a few decades ago and in
the West, the 2000s saw more heat wave events than in any decade of the previous century.12
The
National Climate Assessment has also recognized heat waves becoming more intense and drawn
out and recent years, including 2011 and 2012, have seen several months of extended summer
heat that was unprecedented.17
And while there are relatively few large-scale power outages that
have, to date, been attributed to wildfires, the area burning each year, on average, in the western
U.S. in large wildfires has been increasing over the past 40 years.18
Compared to changes in temperature and precipitation extremes, there is more uncertainty in
changing storm trends across the U.S. However, evidence suggests that, in general, winter storms
have increased in both frequency and intensity, and on average winter storm tracks are shifting
northward.19
There has also been an observable increase in hurricane strength and the number of
Category 4 and 5 Atlantic hurricanes since 1980s, partially driven by warming Atlantic Ocean sea
surface temperatures associated with increased emissions of greenhouse gases.20
PROJECTIONS FOR INCREASING EXTREME WEATHER EVENTS
Both the IPCC and U.S. Global Change Research Program have described projections for further
increases in U.S. extreme weather events in the coming decades, if global greenhouse gas
concentrations continue to rise.12,13
Heat wave frequency and intensity is expected to increase
dramatically this century, and it is possible that by the end of this century the hottest days of the
year will be at least 10o
F warmer than the hottest days between 1981-2000. Even if an aggressive
approach is taken to reduce greenhouse gas emissions, by the 2080s and 2090s the warmest days
of the year will be several degrees warmer than during the 1980s and 1990s. One study found that
what used to be a one-in-20 year heat event could happen every 2 or 3 years by the end of this
century.
Similarly, heavy downpours and flooding are projected to keep increasing in some regions, and
by 2100 the heaviest rainfall events could happen up to five times more often than they do today.
In general, researchers expect that a greater proportion of rainfall will fall in heavy events, even in
regions that are expected to see an overall decrease in total annual rainfall, like the Southwest.

04. EXTREME WEATHER AND CLIMATE CHANGE
The IPCC projects that Atlantic hurricane intensity will keep increasing in the coming decades and
some studies suggest hurricane frequency may also increase, although there remains significant
uncertainty about these future hurricane trends. As mentioned above, recent studies suggest that
as average temperatures continue to rise as projected, the conditions for thunderstorm formation
improve, although further studies are needed to better understand the future risk of more
frequent or intense convective storms.
21. 21 EXTREME WEATHER, CLIMATE CHANGE AND POWER OUTAGES
Our analysis demonstrates that a large majority of the major power outages and electricity
disturbances that occurred from 2003-2012 were caused by severe weather, including storms,
hurricanes, heat waves, and tornadoes. Nearly 150 million customers (which means likely well over
300 million people) were affected by these weather-related power outages.
In addition to individual power loss, interrupted business, and threats to most amenities people
rely on daily, these major outages cost Americans billions of dollars. Recent studies estimate that
weather-related power outages cost between $20 and $55 billion annually.3,4,8
While some recent increases in extreme weather events in the U.S. can be, in part, attributed to
increasing greenhouse gas emissions, it is not possible to say how much this has contributed to
the rise in weather-related power outages. Climate change may be partially responsible, along
with an aging grid infrastructure that is serving greater electricity demand. Yet, future climate
change is expected to bring more severe weather, which will continue to strain our already
vulnerable electrical infrastructure.
