MEMORANDUM April 11 2016 To Committee on Transportation and Infrastructure Subcommittee on Economic Development Public Buildings and Emergency Management Attention Pamela Williams From Richard Campbell Specialist in Energy Policy x 7-7905 Subject Testimony - Blackout Are we Prepared to Manage the Aftermath of a Cyber-Attack or Other Failure of the Electrical Grid Good Morning Chairman Ranking Member and Members of the Subcommittee My name is Richard Campbell I am a Specialist in Energy Policy for the Congressional Research Service CRS On behalf of CRS I would like to thank the Committee for inviting me to testify here today My testimony will provide background on the possible consequences of a failure of the electric grid the roles and responsibilities of the respective parties and some of the objective challenges in the recovery efforts I should note that CRS does not advocate policy or take a position on specific legislation Potential Failure of the Electric Grid The electric power grid in the United States comprises all of the power plants generating electricity together with the transmission and distribution lines and systems which bring power to end-use customers The grid also connects the many publicly and privately owned electric utility and other wholesale power companies in different states and regions of the United States 1 However with changes in federal law 2 regulatory changes and modernization of the electric power infrastructure as drivers the grid is changing from a largely patchwork system built to serve the needs of individual electric utility companies to essentially a national interconnected system accommodating massive transfers of electrical energy among regions of the United States Electricity generation is vital to the commerce and daily functioning of United States While the U S electric grid has operated historically with a high level of reliability the various parts of the electric power system are all vulnerable to failure due to natural operational or manmade events 1 As of 2013 there were 189 investor-owned electric utilities 2 013 publicly-owned electric utilities 887 consumer-owned rural electric cooperatives and nine federal electric utilities American Public Power Association U S Electric Utility Industry Statistics 2015 http www publicpower org files PDFs USElectricUtilityIndustryStatistics pdf 2 Key legislation includes the Public Utility Regulatory Policies Act of 1978 P L 95-617 as amended the Energy Policy Act of 1992 P L 102-486 the Energy Policy Act of 2005 P L 109-58 and the Energy Independence and Security Act of 2007 P L 110–140 Congressional Research Service 2 Electric power is generated and sent over transmission lines to substations which reduce the voltage levels for distribution to end-use customers The cables carrying electric power to customers generally exist in an exterior or “above ground” environment largely exposed to the elements As such power outages can result from floods or seasonal storms which often combine the furies of wind rain snow or ice The more severe weather events can damage electric power transmission and distribution infrastructure as trees or overhanging branches fall on electricity lines Most failures of the grid occur in local distribution systems rather than bulk power transmission systems as the rights-of-way for transmission lines are wider and are cleared to prevent damage from trees The cost of weather-related power outages may range from $25 billion to $55 billion annually 3 Other impairment or failure of the grid can potentially result from attacks terrorism or even extremes of space weather For example a nuclear weapon exploded at a high altitude over the United States would cause an electromagnetic pulse which could destroy power transformers and other critical components 4 Similarly a severe solar storm could have damaging impacts on power transformers Sunspots send plasma from coronal mass ejections into space which could interact with the Earth’s magnetic field causing ground induced currents powerful enough to overload transformers The last major solar flare eruption in 1989 caused blackouts in the Canadian province of Quebec Even greater solar storms occur in cycles of approximately 100 years with major events being recorded in 1859 and 1921 5 Much of the infrastructure which serves the U S power grid is aging As of 2009 the average age of power plants was over 30 years with most of these facilities having a life expectancy of 40 years 6 Electric transmission and distribution system components are similarly aging with power transformers averaging over 40 years of age 7 and 70% of transmission lines being 25 years old or older 8 as of 2007 As the grid is modernized new intelligent technologies utilizing two-way communications and other digital capabilities are being incorporated with Internet connectivity The “Smart Grid” refers to this evolving electric power network 9 While these advances may improve the efficiency and performance of the grid they also increase its vulnerability to cyberattacks launched from the Internet The potential for a major disruption or widespread damage to the nation’s power system from a large-scale cyberattack has increased focus on the cybersecurity of the grid Modernization of many industrial control systems ICS in particular Supervisory Control and Data Acquisition SCADA systems used by electric utilities have also resulted in connections to the Internet 10 The increasing frequency of cyber intrusions on ICS is a concern to the electric power sector Power production and flows on the grid are controlled remotely by a number of IC technologies The National Security Agency reported that it has seen intrusions into IC 3 “Power outages can impact electricity consumers primarily through property loss and business disruption This can result in lost orders and damage to perishable goods and inventories for businesses Power outages can critically affect manufacturing operations mainly through downtime as workers are idled and potentially damage equipment and production processes ” CRS Report R42696 Weather-Related Power Outages and Electric System Resiliency by Richard J Campbell 4 See Congressional Distribution Memorandum Space Weather and EMP threats to

of the need to deploy new technologies Congress indicated its support for grid modernization in the Energy Independence and Security Act of 2007 EISA P L 110-140 Specifically Section 1301 of the act states “It is the policy of the United States to support the modernization of the Nation’s electricity transmission and distribution system to maintain a reliable and secure electricity infrastructure that can meet future demand growth which together characterize a Smart Grid ” 10 CRS Report R43989 Cybersecurity Issues for the Bulk Power System by Richard J Campbell Hereinafter CIBS Congressional Research Service 3 systems by entities with the apparent technical capability “to take down control systems that operate U S power grids water systems and other critical infrastructure ”11 Although there has not been a publicly-reported cybersecurity event or physical attack resulting in a large scale power outage in the United States 12 the potential for such attacks to cause a wide scale long lasting outage cannot be dismissed The first blackouts attributed to a cyberattack happened in the Ukraine in December 2015 13 The power outages affected approximately 225 000 customers and are said to have originated from remote cyber intrusions at three regional electric power distribution companies The cyberattackers targeted industrial control and operating systems at multiple central and regional facilities The cyberattack also targeted other critical infrastructure 14 apparently in an attempt to impair recovery efforts A report15 released by the National Research Council NRC in 2012 concluded that well-informed terrorists could black out a large region of the country for weeks or even months An event of this magnitude and duration could lead to turmoil widespread public fear and an image of helplessness that would play directly into the hands of the terrorists If such large extended outages were to occur during times of extreme weather they could also result in hundreds or even thousands of deaths due to heat stress or extended exposure to extreme cold The largest power system disruptions experienced to date in the United States have caused high economic impacts Considering that a systematically designed and executed terrorist attack could cause disruptions that were even more widespread and of longer duration it is no stretch of the imagination to think that such attacks could entail costs of hundreds of billions of dollars—that is perhaps as much as a few percent of the U S gross domestic product GDP which is currently about $12 5 trillion 16 The NRC report further commented on the potential effects of a combined cyber and physical attack on the grid If they could gain access hackers could manipulate SCADA systems to disrupt the flow of electricity transmit erroneous signals to operators block the flow of vital information or disable protective systems Cyber attacks are unlikely to cause extended outages but if well coordinated they could magnify the damage of a physical attack For example a cascading outage would be aggravated if operators did not get the information to learn that it had started or if protective devices were disabled 17 Similar conclusions were reached in a 2015 report from Cambridge University and Lloyds of London which theorized that a targeted cyberattack could leave 15 states and 93 million people from New York City to Washington D C without power The scenario estimated the total impact to the U S economy at between $243 billion and $1 trillion resulting from “direct damage to assets and infrastructure decline in 11 Peter Behr Cyberattackers have penetrated U S infrastructure systems -- NSA Chief Environment Energy Daily November 21 2014 http www eenews net energywire stories

disruption to the supply chain ”18 The 2013 attack on the Metcalf substation in California further cast light on the physical vulnerabilities of the grid After someone broke into a nearby underground vault to cut telephone cables snipers opened fire on the substation knocking out 17 large power transformers sending power to Silicon Valley A blackout was averted by rerouting power around the substation and local power plants had to produce more electricity But it took the local utility 27 days to restore the substation The Federal Energy Regulatory Commission’s FERC’s chairman at the time Jon Wellinghoff reportedly said that “if the attack were widely replicated across the country it could take down the U S electric grid and black out much of the country ”19 Recovery from a well-planned cyber and physical attack on the grid could be complicated by the cost and vulnerability of critical components While a physical attack on transmission towers to bring down power lines could cause blackouts the strategic destruction of a number of critical high-voltage transformers could cause long-lasting power outages These transformers are very large and difficult to move A large scale attack may use up the limited inventory of spare units 20 and it may take months or even years to build new units The availability of other large components such as high-voltage circuit breakers could also hamper recovery efforts 21 Industry and Government Coordination on Recovery Efforts The electric utility industry generally prepares for power outages from weather-related events and views the potential for a major cybersecurity attack or similar event as a low probability risk As such the industry seeks to balance grid security efforts and expenditures with the perceived risks In the event of a large power outage electric utilities often call upon other utilities via their mutual assistance agreements22 MAAs to help restore services MAAs can help to reduce the duration of weather-related outages by bringing in outside resources to aid the recovery effort If an event is severe enough to be a federally-declared disaster 23 the Department of Homeland Security’s DHS’s Federal Emergency Management Agency FEMA is empowered to provide federal assistance 18 University of Cambridge Centre for Risk Studies and Lloyds of London Business Blackout The insurance implications

industry has several programs for participating companies to share spare transformer equipment For example “ the Edison Electric Institute’s Spare Transformer Equipment Program requires participating utilities to maintain or acquire a specific number of transformers up to 500 kV to be made available to other utilities in case of a critical substation failure Sharing of transformers is mandatory based on a binding contract subject to a ‘triggering event’—a coordinated act of deliberate documented terrorism resulting in the destruction or disabling of a transmission substation and the declaration of a state of emergency by the President and in 2012 NERC initiated its Spare Equipment Database program intended to serve as a tool to ‘facilitate timely communications between those needing long-lead time equipment damaged in a high impact low frequency event and those equipment owners who may be able to share existing equipment being held as spares by their organization ’” See

Assistance Act Public Law 100-707 signed into law November 23 continued Congressional Research Service 5 FEMA’s mission is to reduce the loss of life and property and protect communities nationwide from all hazards including natural disasters acts of terrorism and other man-made disasters FEMA leads and supports the nation in a risk-based comprehensive emergency management system of preparedness protection response recovery and mitigation 24 FEMA can provide financial assistance to electric utilities to aid in disaster recovery efforts In general FEMA will determine a utility’s eligibility and “will cover at least 75 percent of the repair restoration or replacement costs for infrastructure owned by eligible applicants ”25 The electric power industry also works with the Departments of Energy and Homeland Security on a number of cyber and physical security initiatives 26 The Electricity Sub-Sector Coordinating Council ESCC is the principal liaison between the federal government and the electric power sector It represents the electricity sub-sector as part of the Energy Critical Infrastructure sector 27 under DHS’s National Infrastructure Protection Plan NIPP 28 The ESCC draws its membership from all segments of the electric utility industry and is led by three chief executive officers – one each from the American Public Power Association the Edison Electric Institute and the National Rural Electric Cooperative Association 29 Among its activities the ESCC coordinates industry and government efforts on grid security guides infrastructure investments and R D for critical infrastructure protection seeks to improve threat information sharing and processes with public- and private-sector stakeholders and coordinates cross sector activities with other critical infrastructure sectors The bulk electric power system has mandatory and enforceable standards for cybersecurity The Energy Policy Act of 2005 EPACT P L 109-58 gave the Federal Energy Regulatory Commission authority over the reliability of the grid with the power to approve mandatory cybersecurity standards proposed by the Electric Reliability Organization ERO Currently the North American Electric Reliability Corporation NERC serves as the ERO NERC therefore proposes reliability standards for critical infrastructure protection CIP which are updated considering the status of reliability and cybersecurity concerns for the grid FERC recently added mandatory and enforceable physical security requirements to its critical infrastructure protection standards 30 The electric utility industry also conducts a biennial grid security and emergency response exercise GridEx in which electric power and other stakeholders respond to simulated cyber and physical attacks continued 1988 amended the Disaster Relief Act of 1974 Public Law 93-288 It created the system in place today by which a presidential disaster declaration of an emergency triggers financial and physical assistance

However these rules largely do not apply to distribution system utilities which are subject to mostly state regulation FERC Order No 773 establishes a “bright-line” threshold essentially considering all transmission facilities and related facilities operating at 100 kilovolts or above to be part of the bulk electric power system As such these facilities are subject to the applicable NERC reliability standards Congressional Research Service 6 The most recent exercise GridEx III took place on November 18-19 2015 and involved 364 organizations from across North America 31 In the event of a wide-scale power outage caused by a major attack or a disaster electric utility efforts to restore power would likely have to be augmented by state and federal resources Given the potential for damage to the nation’s economy from a major attack on the grid some might suggest a greater focus on recovery is needed and should become as much a part of a grid security strategy as the efforts to secure the system NERC has essentially agreed saying in its GridEx III report that severe emergency situations may require greater coordination with states and the federal government to identify physical risks to electricity facilities and to identify cyber risks in addressing malware on control systems before recovery efforts could begin 32 Congress included provisions to give the U S Department of Energy DOE new authority to order electric utilities and NERC to implement emergency security actions in the “Fixing America’s Surface Transportation Act” FAST P L 114-94 33 DOE is designated as the lead sector specific agency for cybersecurity for the Energy sector 34 Section 61004 of FAST also requires DOE in consultation with FERC NERC and electrical infrastructure operators to develop a plan for storing spare large power transformers and emergency mobile substations which can be quickly deployed to replace damaged large power transformers and substations which serve grid-critical functions 35 Areas for Further Congressional Consideration In any discussion of extended power outages two prominent themes emerge—preparation and recovery If utilities are aware of an impending storm or weather-related event which may cause outages they are expected to make preparations for restoration of services in as timely a manner as possible Recovery from any such event will depend on the severity of the storm and the resulting damage Recovery can be hastened and the amount of damage to electric power infrastructure can be minimized if good maintenance restoration organization and communications strategies are followed on an ongoing basis However a coordinated major cyber and physical attack on the electric grid would severely test the ability of the nation to recover especially as plans for such a recovery are currently in progress The electric utility industry generally bases its response to the potential for such events based on the perceived 31 “The electricity industry participants included chief executives from investor and publicly owned utilities cooperatives and independent system operators from the U S and Canada The U S federal and state governments were represented by senior officials from various departments and agencies In addition approximately 70 individuals associated with the participants attended the tabletop as observers to

61003 of FAST creates a new section 215A of the Federal Power Act that following a written determination by the President authorizes DOE to order utilities the North American Electric Reliability Corporation NERC and Regional Entities to implement emergency security measures for up to 15 days at a time 34 The energy sector is one of 16 critical infrastructure sectors identified in Presidential Policy Directive-21 PPD-21 Critical Infrastructure Security and Resilience Sector specific agencies are designated with specialized expertise in those critical infrastructure sectors that are tasked with various roles and responsibilities for their respective sectors as specified in PPD-21 i e development of sector-specific plans coordination with the Department of Homeland Security and incident management responsibilities 35 Paul Parfomak Electric Grid Physical Security Recent Legislation CRS Insight IN10425 2016 Congressional Research Service 7 risks The industry relies on the federal government to share relevant real-time intelligence on risks from terrorism or cybersecurity threats communicating the quality of threat information in a timely manner so it can respond appropriately Improvements in threat risk assessment would aid this process A focus on recovery would have to consider the mutual dependence and implications to other critical infrastructure especially communications systems 36 of an electric grid failure and how quickly such impacts could proliferate if not planned for in advance Congress may consider how the grid of the future will address cyber and physical security concerns as more distributed generation is incorporated The U S electric grid is evolving Incorporating elements to increase system resiliency as it develops will aid in reducing the vulnerability of the system NERC itself concluded in its report on GridEx III that after a major grid disruption restarting generation and energizing transmission and distribution systems would be a first priority Restoring service to communications systems oil and gas water supply treatment and hospital customers would be a secondary priority Electric power systems may be operating at reduced levels of service and reliability for an extended period at such a time Congress may consider how planning for subsequent restoration of services would proceed to ensure that all civilian communities are kept informed and treated as equitably as possible in disaster recovery efforts 36 “ PPD-21 identifies energy and communications systems as uniquely critical due to the enabling functions they
