3crobrieng on Power Blackout Risks
1. Summar
Blackouts during the last ten ears in Europe and Northern America have demonstrated an increasing likelihood
o supra-regional blackouts with accompaning large economic losses. The earthquake, tsunami damage and
power shortages that idled thousands o Japan’s actories in 2011 highlighted its role as a ke – and sometimes
the onl – source o auto parts, graphics chips and other high-end components. Man manuacturers are currentl
using up the inventories that the had in stock beore the earthquake. A similar situation could occur as a result
o a larger power outage and this risk ma urther increase in the uture. One reason are insucient incentives to
invest in reliable power suppl inrastructures. But new and smarter grids including storage capacities (e.g. pumped-
storage hdropower plants) are required to handle the uture growth o volatile renewable energies, which are
located ar awa rom the centres o demand. Furthermore the vulnerabilit o the power suppl industr, the
industrial and commercial companies and the public and private sector is high due to the interconnectedness
and dependenc o all areas on Inormation and Communication Technolog (ICT), navigational sstems and
other electronic devices.
Whereas short term power blackouts are experienced requentl on a local or regional level around the world
(e.g. caused b natural catastrophe events like earthquakes, storms, foods or heat waves), societies are not amiliar
with large scale, long-lasting, disruptive power blackouts. Traditional scenarios onl assume blackouts or a ew das
and losses seem to be moderate, but i we are considering longer lasting blackouts, which are most likel rom space
weather or coordinated cber or terrorist attacks, the impacts on societ and econom might be signicant.
So ar insurance companies were not aected signicantl beond taking care o their own business continuit
management in order to mitigate losses ollowing a blackout. Risk transer via insurance has usuall required
phsical damage to either the insured’s assets or the assets o specic service providers to trigger a business
interruption claim. But onl 20% to 25% o business interruptions, such as suppl chain disruptions are related to
a phsical loss1. Thereore insured persons and organisations should be aware that the ma ace huge uninsured
losses. This might trigger an increasing demand or new risk transer solutions related to power blackout risks in
the uture.
The insurance industr can oer well contained event covers which ull the pr inciples o insurance: randomness,
assessabilit, mutualit and economic viabilit whereas utilities and governments have to increase their eorts to
make our power inrastructure resilient against such events.

2. Power blackouts challenge societ and econom
Electricit is the backbone o each industrialised societ and econom. Modern countries are not used
to having even short power blackouts. The increased dependenc on continuous power suppl related to
electronics, industrial production, and dail lie makes todas’ societ much more vulnerable concerning power
suppl interruptions. A brownout (reduced voltage) o some minutes or a similar blackout (complete ailure o
electricit suppl) ma cause some inconvenience at home such as having the lights turn o. But a blackout
o a ew hours or even several das would have a signicant impact on our dail lie and the entire econom.
Critical inrastructure such as communication and transport would be hampered, the heating and water suppl
would stop and production processes and trading would cease. Emergenc services like re, police or ambulance
could not be called due the breakdown o the telecommunication sstems. Hospitals would onl be able to work
as long as the emergenc power suppl is supplied with uel. Financial trading, cash machines and supermarkets
would in turn have to close down, which would ultimatel cause a catastrophic scenario. I the blackout were to
spread across the border lines, which is more likel toda due to the interconnection o power grids between
dierent countries, the impacts would escalate as a unction o the duration o the interruption.
The ollowing position paper highlights the risks and uture trends linked to power blackouts. It urther explores risk
management options including operational risk management measures, the importance o a high qualit business
continuit management plan and risk transer options. Furthermore it emphasizes the insurance industr’s options
to expand coverage based on phsical damage and to consider new non-phsical damage insurance solutions.
This might be insurance cover or alternative risk transer solutions, which respond and cover emerging r isks such
as power outages, but also political risks, pandemics and/or suppl chain disruptions.

5crobrieng on Power Blackout Risks
3.1. How power market trends infuence blackout risks
The worldwide power suppl industr experienced two major changes in the last ten to twent ears:
• Liberalisation and privatisation
• Expansion o renewable energ production capacities
3.1.1. liberalisation and privatisation2
Nowadas, most industrialised countries have 10 to 20 ears experience with privatisation and liberalisation o
electricit sstems. The liberalisation o the market resulted in the separation o power generation and transmission
and distribution (T&D) business. This process has created an additional interace which can adversel impact
communication and coordination activities between operators on both sides. The past blackout events reveal ( see
boxes in 3.2.1 and annex ) that underling causes are also partl linked to the privatisation and liberalisation trends
due to missing incentives to invest in reliable, and thereore well maintained, inrastructures. The discrepanc is
urther described in chapter 3.1.3.
3.1.2. renewable energies3
Eorts to mitigate climate change across the world are ocusing on the expansion o renewable energ production
e.g. onshore and oshore wind arms, solar and biomass power plants. Hal o the estimated 194 gigawatts (GW)
o newl added electric capacit worldwide in 2010 is represented b renewable energies which was an increase o
8% compared to 2009. According to the World Wind Energ Association (WWEA), about 175,000 megawatts (MW)
o energ are now being produced b wind power stations around the world. Leading producers are the United States,
China and Spain. The European Union intends to increase the renewable energ share o total energ production to
20% b 2020.

A downside o renewable energ particularl, wind and solar technologies, is the volatile suppl o power. Not onl
ma a scarcit o electricit result in a power blackout, but an oversuppl can also lead to grid instabilities as the
alter the requenc within the network. For example wind energ in East German during strong wind conditions
can provide up to 12 GW, which is more than all German coal and gas red power plants considered together. This
is not critical as long as there is enough electricit demand, but ma lead to grid instabilities in cases o insucient
demand as there is not enough electricit storage capacit available. To get rid o excess electricit, transmission
sstem operators (TSOs) oten have to pa an extra ee to the electricit market (EEX – European Energ Exchange,
Leipzig). Otherwise wind park operators have to be convinced to stop the wind turbines immediatel in order to
prevent grid instabilities and blackouts. Conversel wind turbines must be stopped due to saet reasons i the
wind speed exceeds 30 m/sec. This scenario ma cause, within one hour, power gaps equal to the perormance
o two nuclear power plants. In such cases conventional reserve power plants are required to step in instantl.
In addition, the location o e.g. windarms (onshore and oshore) is oten ar awa rom the centres o demand.
Electricit has to be transported rom sparsel populated regions to large electricit consumers in metropolitan
areas. Thereore, new energ inrastructure (new high voltage transmission lines, transormers and energ
storage capacities such as pumped-storage hdropower plants or thermal storage acilities) are needed.
Grids need to become much “smarter” to handle these enormous technical challenges. Thereore a large-scale
smart grid is needed that integrates and automaticall and ecientl coordinates the activities o all plaers both
on the electricit suppl and the demand side.
3.1.3. Huge investments in power supply inrastructure required5
The ollowing gure rom the grid stud published b dena (German Energ Agenc6 ) shows how man critical
issues have to be taken into account to plan a uture transmission grid that responds to both the increased
proportion o renewable energ production and uture requirements o a modern and sustainable power suppl:

The dena grid stud concludes that or German alone an additional 3,600 kilometres o 380 kilovolt lines will
be required b 2020. For comparison, since 2005 just 80 km o new power grids were erected.
For the European Union grids investments o EUR 23-28 bn are needed over the next ve ears. This could onlbe realised i investment and permitting processes are pushed and nancing incentives or TSOs are supported
b the EU members, regulator bodies and industr.
Worldwide an investment o USD 13.6 trillion will be required b 2030 in order to meet increasing demand
(International Energ Agenc, IEA). IEA concludes that 50% o this amount needs to be invested in transmission
and distribution and another 50% in generation o electricit.
One o the most prominent projects that address these requirements is the Desertec project. The below chart
highlights the necessit o long distance transmission capabilities in order to ecientl use and distribute
renewable energies.

3.2.2. wHat are tHe causes o blackouts?
Tpicall power blackouts are not caused b a single event but b a combination o several deciencies. There is
no outage known where a aultless grid collapsed completel due to a single cause. The ollowing preconditions
are the basis or a high power outage risk:
• High grid utilisation or high power demand
• High power plant utilisation
• Deects due to material ageing
I the ollowing events occur in combination with the above mentioned conditions there is a ver high likelihood
or a power blackout to occur:
• Power plant shutdown or revision or due to suppl ailures (e.g. cooling water shortage during heat waves)
• Unoreseen simultaneous interruptions o several power plants
• Human ailure during maintenance work or switching operations
•Simultaneous grid interruption e.g. short circuit caused b tree contact, excavation work, balloons driting intopower lines, cars hitting utilit poles, provisional shutdown due to electrical overloading risk
• Sudden simultaneous high power demand, e.g. simultaneous usage o air conditions during hot summers
• Power line collapse or electrical equipment breakdown due to natural hazards (e.g. wind, earthquake, snow
or ice load, food, lightning, space weather, extreme temperatures)
• Insucient communication between transmission/distribution sstem operators (TSO/DSO) and power suppliers
• Cber attacks

Power suppl industr is classied as a critical inrastructure. These are organisational and phsical structures
and acilities o such vital importance to a nation’s societ and econom that their ailure or degradation would
result in dramatic consequences.
For this reason, power suppl sstems have alwas been militar targets and can also be in ocus or terrorist
groups which want to undermine economic and social stabilit.
BOMBING:
Acts o war, terrorism and sabotage ma ocus on dams, power plants, substations and high voltage
transmission lines.
During the Korean 1952 war U.S. militar attacked several dams and power plants to wipe out roughl 90% o
North Korean electricit generation.
In April 1995 anti-nuclear energ activists bombed the main 380 kV suppl line or Vienna in Ebergassing
(Austria). Two o the our bombs detonated too earl because o the electric induction too earl and killed theactivists without causing damage to the line.
In Januar 2005 a high voltage line was damaged b terrorists in Georgia.
Several terrorist groups have threathened to destro dams in the U.S., leading to high securit eorts and the
closure o man dams since 9/11.
CyBER ATTACKS:
During the last decade the likelihood o so-called cber attacks increased. Such attacks tr to shut down
or destro critical power suppl components, e.g. large generators or transormers, via the Internet.
Vulnerabilit or cber attacks has risen substantial l due to the ongoing move rom propriet sotware to
IP-(internet protocol) based sstems that use commercial sotware, which can be attacked b intruders.
The U.S. Aurora test in 2007 showed how a generator room at the Idaho National Laborator was remotel
accessed b a hacker and a USD 1 m diesel-electric generator was phsicall destroed.
Another example, the sx virus which was developed to obtain control over the operation o Iran’s nuclear
power plants, demonstrates new possibilities in cber attacks used not onl b individual criminals or terrorists,
but also b oreign states.
HEMP AND IEMI ATTACKS:
It is well known that nuclear bombs emit a strong electromagnetic pulse. I detonated at high altitudes (> 100 km)
above the earth’s surace such bombs are called a HEMP (high altitude electromagnetic pulse) weapon. Alread
in 1962 a militar test 400 km above the Pacic proved the power o such an attack.
As an unintended side eect the power and telephone inrastructure o Hawaii was aected despite the small
bomb (1.4 Mt) and the ar distance (1500 km) rom the point o detonation.
IEMI (Intentional Electro Magnetic Intererence) attacks use special high power electromagnetic weapons without
an o the side eects o a classic explosion and with limited impact area.
Both such weapons have the capacit to cause similar tpes o damage, such as severe solar storms ( see
separate box ). HEMPs or IEMIs can lead to severe phsical damage to all unprotected electronics and transormers
b inducing several 100 to 1000s o volts. Tpicall microchips operate in the range o 1.5 to 5 volts and are
thereore not capable o withstanding such voltages. The impact area can be in the range o several hundred
meters to an entire continent.
In the U.S. the c a h th h u s e p
a (http://www.empcommission.org) researches the eects and mitigation measures to such attacks.

Reliabilit o power suppl varies signicantl across regions (Figure 4 ). Even within OECD countries the qualit o
suppl is not uniorm and power outages quite severl impact econom. The United States, as an example, has an
average o nine hours o disruptions each ear or ever consumer. Those interruptions are estimated to result in
economical losses o least USD 150 bn each ear. Compared to other industrialized countries the reliabilit o the
U.S. grid is 5-10 times less than in major European countries. The average electricit consumer in U.S. has to
cope with approx. 30 times more service interruptions each ear than in Japan or Singapore. U.S. grid stabilit
will decrease in the uture i there are not enough investments in the inrastructure.
The October 2007 stud, “2007 Long-Term Reliabilit Assessment,” o NERC (North American Electric Reliabilit
Corporation) came to the ollowing conclusions:8
• Long-term capacit margins on the nation’s transmission sstems are inadequate to protect these sstems
rom interruptions such as brownouts or blackouts. Absent immediate investments, this condition will worsen
over the next decade;
• Projected increases in peak demand or electricit exceed projected additions o generation capacit;
•
The areas o greatest concern are Caliornia, the Rock Mountain states, New England, Texas, the Southwest,and the Midwest.
• In total, the U.S. will require about 120 GW o new generation just to maintain the minimum 15 percent
capacit margin required or sstem reliabilit.

4. Potential blackout scenario
A regional blackout lasting more than several das alread could be considered as a “worst case” scenario.
Most back-up and securit sstems will ail ater a longer period without electric power, leading to an almost
complete ailure o most critical inrastructures.
As shown beore such a scenario could be caused b a wide range o events.
For example, during the European heat wave o 2003, generation o electricit o power plants, incl. nuclear
plants, had to be reduced due to the scarcit and high temperatures o the adjacent water bodies which are
substantial or cooling purposes. Almost all rivers had record low water levels leading to reduced hdroelectric
generation. Due to the massive lack o wind even wind generation capacit was down signicantl. Prolonged
heat waves ma additionall result in a drop in biomass production due to reduced growth o plants.
I such preconditions coincide with a high electricit demand and increasing instabilit in the power grid, there
is the potential or a supra regional collapse.
A comparable collapse can also be caused b a severe geomagnetic storm or an HEMP attack, due to the simul-
taneous damage to several ke transormer locations and/or high voltage transmission lines. (OECD report 2011.9 )
4.1. Consequences
Most critical sstems such as hospitals, rst responder acilities, water and sewage sstems and stock
exchanges have backup power generation in place. However, these tpicall have onl enough uel or several
hours to a maximum o a ew das.
Immediatel ater a blackout, it is not possible to purchase an goods without cash as no electronic pament
is possible. The 2003 blackout illustrated that ater 3 to 6 hours without power most uel stations and the
reneries had to close down, leaving the public without uel or cars or backup generators as the pumps did

electricit.
Governments have tpicall, however, implemented emergenc uel storages to keep most critical acilities
alive or several weeks up to a month.
Ater one month with no electrical power, water, transportation, emergenc services, critical manuactur ing,
and chemical sectors can ace widespread outages within the aected region. The loss o water sstems due
to a power outage leads to man cascading eects. Hospitals, schools, nursing homes, restaurants, and oce
buildings all rel on water to operate. Water is used or drinking, sanitation, and heating and cooling sstems
in those acilities. Man manuacturing operations either use water as an ingredient in their processes or rel on
wastewater sstems to remove and process their manuacturing waste. Fire ghters depend on water to carr
out their emergenc response, and access to sae water is necessar or providing mass care services and
preventing the spread o disease. Without electricit most heating sstems do not operate. During winter tpical
homes can cool to below reezing level within ew das. It must be expected that people will tr to heat their
homes using open res, leading to man homes burning while there is no water or emergenc response teams.

The term space weather summarizes dierent astrophsical eects the earth is exposed to. Constantl emitted
clouds o electricall charged particles (plasma) rom the sun into space are called solar wind. Large eruptions
o plasma rom the sun‘s corona are known as coronal mass ejections (CME) and create solar storms. The sun
ollows an 11 ear ccle o changing solar activit with the next maximum expected in 2013. During a solar
maximum 1 CME reaches the earth’s orbit ever 5 das on average, while during a solar minimum onl 1 CME
reaches our planet ever 45 das.
A solar storm that reaches earth, generates intensive showers o particles and gigantic cur rents in the ionosphere
(producing bright auroras) and induces major alterations in the geomagnetic eld resulting in a geomagnetic storm.
Large scale electric conductors in the changing magnetic eld, whether cables or pipes, run currents called geo-
magneticall induced currents (GIC). Depending on the underneath geolog long power lines connect (or short
circuit) regions o dierent geoelectric potential. This can trigger GIC (up to 200 Ampere or more over time spans
o more than 10 seconds) to enter the power grid through transormer grounding cables. The electromagnetic
induction is higher the longer the transmission line and more severe or east-west directed transmission lines.
While power grids normall work with alternating currents the are not designed to handle direct currents (like GIC)
induced b a geomagnetic storm. Those currents aect the electricit inrastructure, in particular high-voltage
regulating transormers and substations, but also telecommunication networks and even pipe lines are exposed.
GIC could hold the power to not onl cause tripping o transormers but also damage or even destro transormers,
resulting in a dierent qualit o power outage, i.e. not onl large-scale but also long-lasting.
The rst historical event where GIC appear to be linked to a large loss was a telegraph breakdown on September 2,
1859 – the so-called Carrington event. The da beore, scientists detected a spectacular solar fare that had
triggered a series o CMEs, ollowed b the largest aurora ever reported. At the same time, the extreme geo-
magnetic storm overloaded telegraph lines worldwide, causing short circuits and res in telegraph stations and
ultimatel a breakdown in service.
More recentl on March 13, 1989, during a large magnetic storm accompanied b vivid auroras visible as ar
south as Hawaii and Cuba, GICs hit power lines rom the Hdro-Québec power network. This led to a blackout
aecting 6 million people and losses o more than CAD 10 million. The increasing dependence o societ on
electricit and electronics, and o course satellites (e.g. GPS timing signals), leads to a growing exposure to
strong space weather events, amplied b over-aged or sometimes degraded high-voltage equipment. >

Direct costs o blackouts are lost production, idle labour and acilities, damage to electronic data, spoiled ood
and damaged products, damage to equipment or customer reunds. Indirect costs are looting, accidental
injuries, legal costs, loss o water suppl. In general indirect costs exceed direct ones b up to 5 times.

Analses o historic blackout events in U.S. show average electric customer interruption costs or medium and
large industrial clients o between USD 15,709 or a 30 minute blackout and USD 93,890 or an 8 hour interruption.
There is a wide range o costs depending on the industrial sector (medium & large clients). For an 8 hour event
agricultural rms have the lowest costs with USD 41,250 per event, whereas construction rms have costs o
USD 214,644 – a actor o 5.11

The well known 2003 blackout in U.S. and Canada seems to be the highest economical loss ever during an
outage with an estimated total cost o USD 4 bn to USD 8 bn. But even short blackouts which occur several times
during a ear in the U.S. sum up to an annual economic loss between USD 104 bn to USD 164 bn.
Such short term outages or even just dips in voltage seem to be harmless, however, the can have severe
impacts in case production and suppl chain depend on accuratel snchronised production processes.
Paper manuacturing is a prominent example o such a business, but also the production o semiconductors.
Apart rom the reduced output and the waste o raw materia ls, the inabili t to suppl the customer is critical due
to the ever increasing interdependencies o suppl chains.
Costs per customer dier signicantl between residential, commercial, and industrial customers. The costs can
be described as the Value o Lost Load (VoLL), which is the estimated amount that customers would be willing to
pa to avoid a disruption in their electricit service. Highest costs accrue during the rst hour and then declining

shops. The compan reported that, in total, 10,000 vehicles were moving through the paint shop at the time
o the outage had to be scrapped.
• m c: at Ford’s casting plant in Brook Park, Ohio, the outage caused molten metal to cool
and solidi inside one o the plant’s urnaces. The compan reported that a week would be required to clean
and rebuild the urnace.
• mh o c’: the blackout was responsible or triggering emergenc shutdown procedures
at the Marathon Oil Corporation’s Marathon Ashland rener about 10 miles south o Detroit. During those
procedures, a carbon monoxide boiler ailed to shut down properl, causing a small explosion and the release
o a mixture o hdrocarbons and steam. As a precautionar measure, police evacuated a one-mile strip
around the 183- acre complex and orced hundreds o residents to seek shelter elsewhere.
• n ch c: reported that plant outages resulting rom the August 14 blackout reduced
third-quar ter earnings b USD 10 m or 12 cents per share. The power outage hit production at its Corunna,
Moore Township, Sarnia, and St. Clair River, Ontario, and Painesville, Ohio, acilities.
• d r i.: the largest drug store chain in the metropolitan New york Cit area reported that the
August 14 blackout orced the closure o all o the compan’s 237 stores. The compan estimates that lost

Manuacturers embraced “just in time” production in the 1990s, imitating Japan’s auto makers. The cut stock-
piles o parts and won discounts b buing more parts rom a smaller group o suppliers. But that let them
without a cushion o raw materials to ride out even small disruptions.
As an indicator o the above vulnerabilit, the Earthquake, Tsunami damage and power shor tages that idled
thousands o Japan’s actories in 2011 highlighted its role as a ke — and sometimes the onl — source o auto
parts, graphics chips and other high-end components. In act, toda, man manuacturers are currentl using
up the inventories that the had in stock beore the earthquake. A similar situation could occur as a result o a
larger power outage.

5.1.2. speciic impact based on car manuacturers
The vulnerabilit o automotive manuacturers to the power outages is ver pronounced, as the automotive
industr has been the rst industr to appl just-in-time production. A long suppl interruption means a signicant
risk o stock shortage, resulting in a high risk o production loss.
According to the site www.automotive-index.com, the majorit o the automotive suppliers are still located in
developed countries (Canada, German, U.S., etc.). However, man suppliers are also increasingl located in
developing countries. The energ suppl in these countries is less reliable, as can be seen in Figure 7. When
comparing the map o electrical power suppl b countr with the map o car manuacturing (Figure 8 ) and their
suppliers, it becomes obvious that the spread o locations show a signicant production in countries with lower
power reliabilit, such as Turke, India, Malasia and Indonesia.

5.2. Business Continuit Planning to mitigate power blackout risks
A well organised and implemented business continuit plan (BCP) is v ital or the survival o a compan
in case o a power blackout, as well as to gain access to insurance solutions or such risks. The holistic structure
o BCP includes both a compan’s internal actors, such as organisation, inrastructure and inormation and
decision-making channels, and external actors, such as technolog, customers, suppliers, environment, nature
and social setting.
A successul BCP bases on a r isk analsis which consists o
• Risk Identication Analsis (RIA)
• Risk evaluation
• Risk mitigation/adaption
• Risk Control
Once the risks have been identied and evaluated, it is advisable to draw up a list o measures. This will showthe energ compan specic areas o weakness o an business interruption in a sstematic wa. Examples o

At the end o the threat analsis, the ollowing ke questions ar ise regarding business continuit management.
• Are the critical unctions and processes in the compan dened?
• Does useul documentation exist concerning requenc, scale and causes o business interruptions?
• Do comprehensive disaster recover plans exist where the necessar strategies, data and operating
resources are laid down or business recover?
• Are the IT and communication sstems sucientl protected, so that the can resume operation within
the required time ollowing incidents?
• Are there plans which are tested and updated regularl b means o practice drills?
description o business continuity planning (bcp) elements
b
concerns all divisions o the compan and requires cooperation at all hierarch levels. Onl a clearl structured
business continuit organisation can ensure that strategies are developed, established, maintained and properl
implemented in an emergenc.
People involved in preparing and maintaining the business continuit plan need to be acquainted with the
compan’s inrastructure and processes and suited to the tasks in question. Responsibilities within the BC
process as a whole need to be clearl dened at all times.
The top position in the BC management should be held b a representative o the highest compan level to
ensure high strategic priorit within the compan. A crisis team could operate locall and objectivel in the
closest possible proximit to the emergenc while emergenc service teams were saeguarding the inrastructure
and recover teams were alread starting with specic disaster recover activities.
b i a (bia)
is the cornerstone o BCP, as it orms the basis o the urther recover strateg. In order to determine the relevant
business processes at risk o ailure and describe them in detail in terms o their importance and impact, questions
are put to the senior management. Based on the inormation received, an analsis is carried out to ascertain how
long the compan can continue to operate without its existence being jeopardised i areas identied as being at
risk ail. Here, an interdependenc and contingenc losses arising rom the power outage must also be taken
into account.

The result should be a group-wide business continuit guideline that denes the ke data o the BCP and which
the entire Board o Management approves as a binding requirement. The BC guideline will include the business
continuit organisation, the business continuit master plan and all the measures or maintaining, exercising,
auditing and developing the BCP.

The best business continuit planning can ail in an emergenc i it is not constantl adapted to current
conditions and regularl practised. Tests, training, audits and simulations are the supreme discipline o business
continuit planning.
Internal and external audits are also used to ensure the qualit o BCP. To this end, as part o its responsibilities,
the BC management checks whether the rules agreed beorehand are complied with in the individual business
units and whether the BC organisation and BC set-up tall with the planning in everda lie.
As a result o the increased reduction o redundancies and the outsourcing outlined beore, the BCM Manager
has to include power suppl as one o the business critical processes into the BCP.
This could be addressed in var ious was:
• Ensure, that or business critical processes multiple sources are available
• Ensure, that the impact o a power outage is reduced b investing in technical backup units (e.g. emergenc
power suppl)
• Ensure, that cost benet analsis relocating or outsourcing business critical processes take the additional risk
o power outages into account, which might lead to the decision to locate the process in another countr than
originall planned.
5.3. Risk transer solutions

Insurance clients benet rom protection against unexpected losses and peak risks as well as reed up capital
which can be deploed otherwise. The insurance industr enables thereore economic growth and innovation b
reducing volatilit and providing capital relie. Depending on their needs and the insurance markets’ productrange, coverage extent and conditions var. In order to transer risks to the insurance industr a set o criteria
has to be considered:
• r: The time and location o an insured event must be unpredictable and occurrence itsel must
be independent o the will o the insured (i.e. accidental).
• a : The requenc that an event will occur and severit o the resulting damage can be estimated
and quantied within reasonable condence limits.
• m: A large number o endangered parties must join together to build a risk pool in which risk is
shared and diversied at economicall air terms.
• e : Insurers must be able to charge a premium that corresponds to the underling risk
including capital costs and expenses.

5.3.2. current risk transer solutions
Thereore, blackout related risks can be separated into insurable versus not insurable r isks.
i
• Propert damage (PD), business interruption (BI ), insurance or utilities
• BI extensions insuring ailure o power suppl or commercial and industrial enterprises
• PD insurance or private households
n
• Unlimited and uncontrolled covers or generall insurable exposures
• Frequent losses (e.g. short term power blackouts)
• Operational risks
Electricit producers, distributors and consumers o electricit have various options to insure risks arising rom
power outage.
e
Producers usuall bu propert damage and business interruption insurance. These covers cushion or prevent
nancial loss due to a reduction in turnover, i such reduction is due to material damage to insured propert
on the insured premises. Covered perils are re, explosion, social perils and natural perils in re business
interruption insurance and various tpes o machiner ailures in respect o machiner breakdown insurances.
In general, distributors o electricit have the same options or business interruption coverage as producers.
Since the distribution net with its transmission and distribution lines is usuall heavil exposed to natural perils
such as wind, ice storm and earthquake, insurance coverage ma be limited regarding both propert damagewhich triggers BI and insured perils.
BI insurances or both producers and distributors usuall avoids requenc losses b respective monetar
deductions. These provide or sel-insurance b the insureds in case o minor interruptions in electricit suppl.
Some airl new insurance products oer nancial income protection against adverse weather conditions.
These normall appl to reduced electricit consumption ar ising in connection with warmer than expected winter
seasons, i.e. do not depend on accidental loss events. Oten such covers are determined b indexes – so-called
parametric covers – rather than b the actual loss sustained as is the rule in Propert and Casualt insurance.
In addition, special BI extensions exist which cover nancial loss in connection with ailure to produce or deliver
electricit ollowing malunction o data that was not caused b a phsical loss or damage. Insured perils include,
data corruption or malunction o data due to operating errors, hacker attacks or data malware.
c
Consumers range rom industrial and commercial enterprises to public authorities. Industrial and commercial
enterprises bu insurance against both material damage and BI due to ailure o electricit. Usuall or both tpes
o covers material damage on the premises o the insured is required. Such coverage onl exceptionall includes
the transmission and distribution lines as the accumulation potential is considered to be high. In case the eared
event does not occur at the insured’s location but at a supplier’s site, this tpe o BI extension is called dependent
BI or contingent BI.

5.3.3. uture risk transer products
Phsical damage to premises or distribution lines o electricit producers and distributors are likel to remain
the main exposures. Contingent BI exposures remain the most important eature or electricit consumers.
Subject to an increasing trend or electricit interruptions, consumers’ preparedness to bu specic insurance
coverage is likel to increase. The insurance industr ma be able to include the most requent ailures due to
damage to transmission and distribution lines and consequentl manage the increased accumulation potential.
Nonphsical damage business interruption insurances, like coverage or fuctuations in the weather pattern,
volcanic ash clouds or pandemics, will hardl become more than complementar. Reasons or this are the
accumulation potential, the low number o insurers prepared to oer coverage, high premiums, scarce capacit
and a small number o interested parties to bu such coverage. However, additional elements o nonphsical
damage coverage ma be designed to cater or specic needs o industrial and commercial clients. Perils that
could suit such purpose are a lack o cooling water or power plants due to extended periods o drought or
interruption o electricit production due to saet measures required b public authorities. Interruptions due to
saet concerns have recentl taken place in Japan as a consequence o earthquake damage to the Japanese
power and distribution industr.
BI insurance not based on phsical damage ma, in addition, move awa rom the indemnit principle. Fixed sums
insurances or BI loss could use parametric triggers such as the number o hours or das o electricit ailure.
5.3.4. residual risk acceptance
The risk that remains with the threatened subject is the residual risk. It is either not insured or not entirel
insured:
• One o the main reasons or not insuring an insurable exposure is the amount o premium required
or coverage.
• Insurers accept onl a part o insureds’ exposures. The introduce sub limits, risk or loss retentions.
• The boundaries between insurable and noninsurable risks are not clear cut. In some instances seemingl
noninsurable risks can be made insurable (high risk retentions and exposure limitations). Furthermore, the
insurance market is developing and extending the limits o insurabilit. However, insurabilit generall ends
where the occurrence o the eared event or the date o occurrence (e.g. in lie insurance) is not ortuitous
anmore.
Potential insureds need to customise their insurance protection considering the above mentioned restrictions
and accept some residual risk.

25crobrieng on Power Blackout Risks
6. Conclusion
The power blackout risk is generall underestimated. Blackouts during the last ten ears in Europe and Nor thern
America have demonstrated an increasing likelihood o supra-regional and long-lasting blackouts including high
economical losses. Due to the increasing interconnectedness in combination with rather old inrastructure we
expect this risk to increase in both requenc and severit.
Politics have to establish clear rameworks or the governance o power suppl inrastructures. This is a necessar
step to enhance resilience o power grids. The main responsible stakeholders who have to take care o a reliable
power suppl are public and private utili ties as well as sstem / network operators.
Insurance buers have to be aware that the ma suer during a blackout noncovered losses which require pre-
cautions against damages. For the insurance industr this might trigger an increasing customer demand not onl
or power blackout risk solutions, but also or suppl chain and nonphsical business interruption risks in general.
It presents a great challenge, however, to handle those intangible risks while also oering a great opportunit to
invest in the development o tailored insurance products (potentiall combined with busines continuit management
services) which ull customer demand and the requirements or insurabilit. Furthermore insurers need to review
their own BCM capabilities concerning blackout risks to make sure that the can provide services even in the case
o long-lasting blackouts.
When risk management is done well and risks can be reliabl quantied, insurance is an important mechanism
or risk transer. All parties, insurers, electricit industr and consumers should engage in risk dialogues to pro-
activel address and manage related power blackout risks with the aim to maintain one o the most important
goods in a civilized societ, a reliable suppl o electricit.

7. Annex
b 2003, u.s./c14/15/16
wh h?
On August 14, 2003, large portions o the Midwest and Northeast United States and Ontario, Canada,
experienced an electric power blackout. The outage aected an area with an estimated 50 million people and
61,800 MW o electric load in the states o Ohio, Michigan, Pennslvania, New york, Vermont, Massachusetts,
Connecticut, New Jerse and the Canadian province o Ontario. The blackout began a ew minutes ater
4:00 pm Eastern Dalight Time and power was not restored or 4 das in some parts o the United States.
Parts o Ontario suered rolling blackouts or more than a week beore ull power was restored.
c:
The blackout had several causes or contributor actors:– Inadequate vegetation management (line contact b trees);
– Failure to ensure operation within secure limits;
– Failure to identi emergenc conditions and communicate that status to neighbouring sstems;
– Inadequate operator training;
– Inadequate regional-scale visibilit over the power sstem;
– Inadequate coordination o relas and other protective devices or sstems;
– Inadequate interregional visibilit over the power sstem;
– Dsunction o a control area’s sstem;
– Lack o adequate backup capabilit to that sstem.
i:
In Canada, gross domestic product was down 0.7% in August, there was a net loss o 18.9 million work hours,
and manuacturing shipments in Ontario were down USD 2.3 bn. The losses were mainl related to perishable
goods spoilage, production and computer equipment shut down and business income losses.
In United-States, Anderson Economic Group estimates the likel total cost to be between USD 4.5 bn and
USD 8.2 bn. This includes:
– USD 4.2 bn in lost income to workers and investors;
– USD 15 m to to USD 100 m in extra costs to government agencies (e.g. due to overtime and emergenc service
costs);
– USD 1 bn to USD 2 bn in costs to the aected utilities;
– between USD 380 m and and USD 940 m in costs associated with lost or spoiled commodities. >

27crobrieng on Power Blackout Risks
The U.S. Department o Energ (DOE) has published a total cost estimate o about USD 6 bn. This number is
the most requentl cited cost estimate in press coverage o the blackout.
A post-blackout stud underwa b CrainTech (a business news publisher) , Case Western Reserve Universit’s
Center or Regional Economic Issues and Miriex Sstems LLC has produced some preliminar results based
on a surve o businesses in Ohio, New york, Pennslvania, Michigan, Wisconsin and Southern Canada.
These ndings include:
– A quarter o the businesses sur veed (24%) lost more than USD 50,000 per hour o downtime
(i.e., USD 400,000 or an 8-hour da). And 4% o the businesses lost more than USD 1 m or each hour o
downtime.
– Almost 11% o rms sa the blackout will aect their decision-making with regards to either growth at the
current location or relocation to another.
An impor tant indirect—and impossible to quanti—cost o the blackout was the “cascading” consequences
on regions outside o the blackout ootprint created b manuacturers’ just-in-time (JIT) production scheduling.Deliver times or parts and materials to assembl plants are timed to meet scheduled production and thus
minimize or eliminate the cost o inventor.
On April 22, 2009, the Appellate Division o the New Jerse Superior Court published its March 9, 2009 opinion
holding that the massive August 14, 2003 electrical blackout o the eastern United States and portions o Canada
inficted “propert damage” sucient to support a propert insurance claim. The court held that the loss o
unctionalit that resulted when protective saet equipment shut down the power grid and caused the blackout
qualied as “phsical damage” or propert insurance purposes. As a result, insurers were not entitled to
summar judgment in their avour on claims (e.g. or ood spoilage and business interruption) resulting rom
the blackout.

wh h?
• 28th September 2003: Italian power sstem aced its worst disruption in 50 ears, which also aected
parts o Switzerland with 56 million people in total
• Electricit was restored ater 1.5 hours (CH) and 18 hours (Ital)
c:
• Inabilit o the Swiss sstem operator to reclose the Mettlen-Lavorgo line ater its initial ailure.
•
Ineective communication and subsequent slow and ineective emergenc responses b the Swissand Italian sstem operators.
• Angle and voltage instabilit in Ital just prior to its collapse.
• Insucient tree cutting under the power lines.
i:
• Beside Switzerland and Ital, the networks in France, Slovenia, and Austria were aected and the blackout
led to a domino eect that ultimatel resulted in the separation o the Italian sstem rom the rest o the
European grid. >

• 30,000 people were trapped on trains.
• Several hundred passengers were stranded on underground transit sstems.
• Signicant knock-on eects across other critical inrastructures, commercial and domestic users which
suered disruption up to 48 hours.
• Subwa had to be evacuated.
• Cost to restaurants and bars in spoiled products and lost sales totalled up to USD 139 m.
blackout 2006, germany incl. western europe 20/21/22/23
wh h?
• On November 4, 2006 the German TSO E.ON Netz had to switch o a high voltage line to let a ship
pass underneath.
• Simultaneousl there was a high amount o wind electricit which ed into the grid 10,000 MW rom
wind turbines to Western and Southern Europe grids.
• Insucient communication about this switch-o led to instabilities o the requenc in the grid and
to overloading o lines.
• Devices had to switch customers o in the countries aected to cope with this lack o power in the
Western zone automatic.
• The blackout lasted up to two hours.
c:
• Ater manual disconnection o the high-voltage line the n-1 criterion o process securit was not ullled.
N-1 criterion means that an component ma ail and all other components are still below their limit.
As a result, even a relative l small power fow deviation could trigger the cascade o line tripping.
• Insucient co-ordination between transmission sstem operators.
• No access to real-time data rom the power units connected to the distribution grids.
• Lack o joint simulation training with neighbouring transmission sstem operators.
• Lack o coordination between operators’ internal procedures regarding grid-related, market-related and
other adjustments.
i:
• In France 5 million customers were cut-o.
• In German millions o customers were aected and in Belgium, Netherlands, Ital and Spain some
hundreds o thousands o customers were without electricit.
• Long delas in rail transport, aecting about 100 trains mainl in German.
• Subwa had to be evacuated.
• Costs to restaurants and bars in spoiled products and lost sales totalled up to USD 139 m.

nuclear catastropHe ollowing an eartHquake and tsunami triggered
station blackout, Japan 2011 24/25/26
The complete power suppl cut o o the nuclear power plant in Fukushima Dai-Ichi, Japan in March 2011
led to severe damages in the reactor units 1, 2 and 3 and resulted in signicant emissions o radiation into the
atmosphere. The tsunami which fooded the emergenc diesel generators caused the on-site power blackout
so that the operator was unable to keep the cooling sstems running. This power outage is a so called station
blackout (SBO). The impact was tremendous:
• Fukushima is rated as serious as the Chernobl catastrophe – magnitude 7 event, the worst on the
international nuclear event scale though Fukushima released onl 5 to 10% o the radiation released
b Chernobl.
• Mandator evacuation zone or all residents within 20 km.
•
Voluntar evacuation o all residents between 20 and 30 km.
• Agricultural products including milk and vegetables rom the region got contaminated.
• Decades will be required or cleanup and containment.
• Estimates on reinsurers’ share o losses rom the Japan disaster could be between USD 20 bn and USD 30 bn
out o the disaster’s total gross loss estimated at USD 40 bn to USD 65 bn. These estimated losses would
exceed the 20 bn to USD 25 bn in losses ceded to reinsurers rom the 9/11 terror ist attacks, and the USD 18 bn
to USD 24 bn incurred b reinsurers rom Hurricane Katrina in 2005.
As a consequence o the earthquake and tsunami three other nuclear plants, six coal-red plants and 11 oil-red
power plants were shut down. This is 11 percent o Japan’s total power. As a consequence actories had to
operate at reduced levels, which will have a signicant impact on Japans’ econom. JPMorgan Securities Japan
estimates that the countr’s gross domestic product will shrink in the second quarter b about 3% on anannualised basis, with about hal o that decline resulting rom the power shortage.
