5 Part 1 INTRODUCTION 1.1 Electricity Market Electricity is a commodity that most take for granted. It is expected to be available at the flick of a switch, and the market provides a level of service to ensure that it is 1. Its importance is decidedly understated; until it is taken away. Twenty-first century living is wholly reliant on electricity; we need it to power our homes and offices, our telecommunications and media, and more importantly, it powers all the essential infrastructure and services a functioning society needs. Consequently, a severe supply disruption is potentially a serious, costly and distressing event. To counter the risk, industry has adopted best business practices aligning their processes to Australian and International standards, while Government, in its capacity as the regulator, has implemented targeted regulation in areas of vulnerability. Network Operators endeavour to maintain an extremely high level of system reliability 2, balancing their networks by utilising dynamic load information, supply and demand projections and maintaining a standby fleet of service crew at all times. More importantly, it is the continual pursuit of safety throughout the entire supply chain that has a direct impact on mitigating the risk of a supply disruption. Industry participants are resolute in their promotion of safety levels and risk prevention measures, which corresponds with increased system security through: reduction of accidents, proactive maintenance and more effective use of resources (human and equipment). Figure 1 Electricity Supply System However, supply disruptions are inevitable. Western Australia has a history of naturally occurring hazards that are unpreventable. Tropical Cyclones in the North West, storms in the South West, floods and bushfires, all serve as catalysts for supply disruptions. The supply system is technically complex, dealing with an inherently dangerous and dynamic form of energy. The various parts of the supply chain either directly or indirectly interact with each other, forming a correlation between the operation of a singular asset 1 Electricity Industry (Network Quality and Reliability of Supply) Code Westplan Electricity Supply Disruption Page 5

6 and an occurrence elsewhere within the chain. An incident involving one particular component can set off a chain reaction that cascades, affecting a wider service area and far outstripping the impact the initial issue belies. This was clearly demonstrated by the Northeast blackout of the United States where 55 million people lost power as the result of a software bug and overgrown foliage. WESTERN AUSTRALIAN ELECTRICITY NETWORK Western Australia has a fragmented electricity system due to its geographical size. It has 42 individual network and service areas, serviced by eight system operators, and another 12 communities responsible for their own power. Between the eight operators they are responsible for covering a potential service area in excess of 2.5 million square kilometres. Of these service areas the three most significant are the South West Interconnected System (SWIS), the North West Interconnected System (NWIS), and Rio Tinto s network in the Pilbara. Western Australia s largest urban areas are captured by the SWIS. The SWIS runs from Albany in the south to Kalbarri in the north, and also captures the Goldfields. This results in the transmission of energy to over a million customers. This sophisticated network is operated by Western Power, that maintains responsibility for ensuring the safe and reliable provision of electricity within the service area. The SWIS has a number of natural redundancies built in, as the interconnectedness of the system allows electricity to flow via different paths to the consumer. The second largest service provider is Horizon Power which operates the NWIS in the Pilbara as well as 37 discreet service areas and covers 2.3 million square kilometres. Its role in the supply chain differs from Western Power, as it is also responsible for generation and retailing on its network. Horizon Power plays an important role in supplying much needed electricity to a number of the remotest communities in Western Australia. Western Australia s resources sector is reliant on reliable sources of energy, as delays in operations prove costly. As a direct result, resource sector companies, particularly larger operators in the Pilbara, have invested heavily in energy infrastructure connecting large mine sites to generators, and in a number of instances provide important electricity sources to remote mining towns. Within Western Australia the two primary fuels for electricity generation are gas and coal. While other fuel types such as liquid fuel and wind are prevalent, the State has a fairly heavy reliance on gas for its generating requirements. As represented by Figure 2, generators are positioned as close to their fuel sources as permissible. There are a number of small and very remote communities primarily reliant on themselves to generate power. These isolated communities face an intrinsic risk of supply disruptions given their physical locality. With the assistance of the Department of Housing and third party service providers these communities operate and maintain their own essential service infrastructure.

8 1.2 Aim and Objectives AIM The aim of Westplan - Electricity Supply Disruption is to detail Western Australia's emergency management arrangements to electricity supply disruptions that meet the definition of the hazard (see 1.4 Hazard Definition below). OBJECTIVES The objectives of this Westplan are to: describe how the incident management framework will operate - specifically how the response effort will be triggered, activated, coordinated, analysed and improved describe the incident management structure, including the joint industry/government arrangements for the management of electricity supply disruption emergencies define the role of the Coordinator of Energy as the Hazard Management Agency (HMA), and other government and non-government organisations in the operational planning and incident management of electricity supply disruption emergencies provide advice on the need for individual persons, businesses and other entities that rely on electricity to assess their risks and have contingencies in place to manage them. 1.3 Scope Westplan Electricity Supply Disruption (the Westplan) applies to all licensed and licence exempt service areas, and remote communities identified under the National Partnership Agreement on Remote Indigenous Housing 3, in Western Australia. All reference to the roles and responsibilities of government departments and industry organisations under this Westplan, is specific to the principles of emergency management. These organisations operate within these parameters through business as usual principles, compliance with legislation or via a bilateral agreement with the HMA. Not all electricity outages constitute an emergency under these arrangements. 1.4 Hazard Definition Electricity supply disruption is defined as loss of or interruption to the supply of electricity that is capable of causing or resulting loss of life, prejudice to the safety, or harm to the health, of a person 4. Special Consideration To better define the scope of the response to a electricity supply hazard the following considerations are made: Any disruption to electricity supply has the possibility to result in the loss of life. In addition, a significant electricity supply disruption can constrain the amount of energy available to industry, community and Critical State Infrastructure. Potential impacts faced by the community and which could exacerbate the effects of the definition are: - disruption to essential services, i.e. water and health care Emergency Management Regulations (l) Westplan Electricity Supply Disruption Page 8

9 - disruption to vital economic service, i.e. telecommunications and banking - disruption to public transport train services - safety issues surrounding public lighting and traffic management - impact on vulnerable populations - economic loss both public and private. 1.5 Related Documents Documents upon which elements of this plan rely include: State Emergency Management Policy (SEMP) documents (HMA) Operations Plan: (E) Electricity (HMA) Operations Plan: (C) Communications Crisis & Emergency Management Plans 5 (various) Westplan - Gas Supply Disruption Westplan - Liquid Fuel Supply Disruption Westplan - Cyclone Westplan - Storm Westplan - Fire Westplan - Flood Westplan - Heat Wave Westplan - Recovery Coordination Westplan - Emergency Public Information Westplan - Welfare 1.6 Authority to Plan Under Section 20(1) of the Emergency Management Act 2005, the State Emergency Management Committee (SEMC) is responsible for ensuring the preparation of Westplans it considers as necessary. In accordance with State Emergency Management Policy (SEMP) 2.2 the Coordinator of Energy, Public Utilities Office is responsible for the development and review of the State Emergency Management Plan for electricity supply disruptions [Westplan Electricity Supply Disruption]. 1.7 Plan Responsibilities The development, implementation and revision of the Westplan is the responsibility of the HMA with support of the Electricity Supply Emergency Committee (ESEC). Advisory Groups The ESEC was established as an advisory body to advise and assist with non-operational strategic planning for the management of electricity supply disruption incidents. Details on the ESEC can be found in Appendix C. 1.8 Exercise and Review Exercising The plan is to be exercised annually through desktop or simulation exercises, in accordance with SEMP 3.1. The formal operational activation of the Westplan may satisfy the requirement to exercise in compliance with SEMP Service providers have established crisis and emergency management plans. Westplan Electricity Supply Disruption Page 9

10 Review Westplan Electricity Supply Disruption is to be reviewed once every five years or more frequently, if appropriate, in accordance with SEMP Organisational Roles The aspects of emergency management 6 are prevention, preparedness, response and recovery. Organisations named in this Westplan with responsibilities for prevention, response and recovery have an intrinsic alignment to these aspects and are already governed by charters, mission statements, ethical business practices and legislation. Organisations responsible for assisting the State in preparing for supply disruptions voluntarily adopted this responsibility by requesting and/or accepting membership to the ESEC. Details of the roles and responsibilities of organisations related in this plan can be found in Appendix C. 6 Emergency Management Act 2005 Part 1 (3) 'emergency management' Westplan Electricity Supply Disruption Page 10

11 Part 2 PREVENTION AND MITIGATION 2.1 Electricity Supply Vulnerabilities An electricity supply disruption emergency can result from any or a combination of the following events: Natural Hazards: Cyclone, Storm, Bushfire, Earthquake: Western Australia is prone to a number of natural hazards, all with the potential to affect electricity supply. Size, direction and strength of the natural hazard, all influence the risk of failing infrastructure, while geographical location will impact on the restoration of services. Equipment Failure: Incidents involving equipment failure can arise at all points in the supply chain, from generation to distribution. The severity of the resulting disruption corresponds to the importance of equipment and the extent of the failure. Accidents: Accidents as a result of human error occurring on key infrastructure are of a similar category as that caused by equipment failure. Terrorism: Physical and Cyber attacks are becoming increasingly more sophisticated and prevalent. An attack of this nature can leave lasting damage or delay repairs until the sites have been cleared by Western Australia Police. Gas and Liquid Fuel Supply Disruption: A significant proportion of the State s electricity generation is provided by gas-fired generators, some of whom have the ability to switch to burning diesel. A disruption to the State s gas supply results in fuel switching, increasing demand for diesel; subsequent disruption to the availability of diesel fuel will affect the electricity market. 2.2 Responsibility for Prevention Industry, through good business practice and Government, with regulation, endeavour to reduce the risk and potential impact to the community. Legislation targets aspects of the market that are noticeably vulnerable, while industry, in the pursuit of safety, align their processes to licensing and legislative requirements. This constitutes a whole of supply chain approach to preventing such disasters. Figure 3 on page 13 is indicative of the numerous measures that assist in the prevention of supply disruptions. While events like natural disasters will never be able to be prevented, the regulation, processes and practices within the market all lend themselves to mitigate the risk posed by supply chain vulnerabilities. 2.3 Prevention and Mitigation Strategies While there are a number of drivers within industry to ensure effective and productive operations, there are two prevalent themes: safety and the commercial imperative to maintain supply. Safety, in the operation of electricity infrastructure, has the effect of reducing the likelihood of accidents that can, in turn, result in the interruption of supply and/or irrecoverable business losses. Industry participants heavily regulate the safety of their workforce, and combined with the legislation and regulating authorities, are very effective at minimising interruptions. The pursuit of safety also entails a rigorous certification process when working in and around the infrastructure. There is also a commercial imperative for market participants to maintain effective operations. This drive for reliability results in the better management of assets, adoption of best industry practices and increased operational times to maximise returns on assets. Westplan Electricity Supply Disruption Page 11

12 The market continually evolves to find better and safer ways of operating. This results in improvements to the security of supply. As a result, both the pursuit of safety and commercial efficiencies collaborate to mitigate the risk and impact of supply disruptions. However, not all risk is preventable. Market participants have therefore applied a thorough application of risk management practices and have subsequently built a suite of redundancies into their systems and operations. Essential service providers in particular have been robust in their planning and implementation of redundancy strategies. Finally, Government will always assess the risk facing the State and community and provide appropriate legislation and policy to mitigate the negative effects of an incident.

15 Part 3 PREPAREDNESS 3.1 Responsibility for preparedness As the HMA, the Coordinator of Energy is responsible for coordinating State-wide preparedness activities for the management of electricity supply disruption incidents. The Coordinator of Energy is assisted by the Public Utilities Office and the ESEC. Industry participants also carry a responsibility to prepare for those factors that might result in a supply disruption and consequential emergency responses. 3.2 Planning and arrangements In preparation for a severe disruption, several agencies 11 have prepared arrangements, either wholly or in part; these arrangements include- Westplan Electricity Supply Disruption (strategic plan) o Operations Plan: (E) Electricity (operational plan) o Operations Plan: (C) Communications Westplan Recovery Coordination Westplan Emergency Public Information State Emergency Management Policies The Public Utilities Office will undertake the planning and implementation of preparedness activities in collaboration with the ESEC. These include: establishing a programme to test the Westplan and the associated Operations Plan(s) providing advice on, and participating in, regular exercises and workshops contributing to response planning and regular reviews of the strategic and operational plans. The Coordinator of Energy may invite other relevant stakeholders to participate in the ESEC or in annual exercises. Where appropriate, the testing exercises may be carried out in conjunction with other exercises conducted by industry, government and/or by direction from the SEMC. The HMA, in compliance with SEMP 3.1, will provide a Post Exercise Report to the SEMC and, where required, a list of actions detailing improvements to the Westplan and timelines for delivery. 3.3 Special Needs Groups Special needs groups will be identified during an incident through consultation with the Operational Area Support Group (OASG). The OASG will comprise those government agencies that are responsible for the following demographics: Consumers with life support equipment 11 Such as: HMA, ESEC, DPC, WA Police, SEMC Secretariat Westplan Electricity Supply Disruption Page 15

16 Preschool and school children Aged care recipients Electricity retailers are required to maintain a list of critical use customers and locations of life support equipment. Consumers that have life support equipment requirements are advised to contact their energy retailer to register their details. 3.4 Resources In the event of an electricity supply disruption, the HMA will work with stakeholders to coordinate the response to the effects of the hazard. To facilitate the response the HMA has implemented a crisis information management system. The HMA is responsible for maintaining this system. Organisations with roles and responsibilities identified in Appendix C of the plan should ensure that they have necessary resources in place to effectively meet their obligations during an electricity supply disruption. Operations Plan: (E) Electricity details the resourcing requirements of the HMA. 3.5 Training The HMA is responsible for ensuring staff maintain the necessary level of operational readiness. It will do this through: Annual exercises Workshops Seminars and industry information days Internal (targeted) training plans. Organisations with roles and responsibilities identified in Appendix C of the plan should ensure their staff are provided with the necessary training, and have a good understanding of procedures and arrangements in the Westplan. Annual exercises facilitate the instruction of the arrangements and familiarise responders with the actions of the HMA. The HMA is responsible for training relevant industry stakeholders in the use of its crisis information management system. 3.6 Community Information As with all energy resources, it is not possible to guarantee the continuity of electricity supply at all times. Industries, businesses and residential consumers heavily reliant on electricity should be aware of their potential exposure to a shortage of energy. It is advisable that they assess their own risks and have contingencies in place to manage them in such an event. Businesses should maintain a risk register and business continuity plans. The HMA has adopted the risk management standard of ISO:31000/2009. Individuals can find useful information at: The Public Utilities Office provides information, reviews and strategic reports on Western Australian energy through its website, publications and participation at events. Other online resources that contain useful information relating to the energy market and safety: Independent Market Operator Horizon Power Western Power Westplan Electricity Supply Disruption Page 16

17 Synergy EnergySafety Department of Fire and Emergency Services The HMA recommends all consumers note the Department of Fire and Emergency Services emergency information material on being prepared for natural hazards. The items contained within the emergency kits will assist in outages 12. During a electricity supply disruption, media campaigns planned and implemented by the HMA and industry will also assist in providing the community with information and tips on reducing non-essential energy use as well as health and safety. 3.7 Arrangement for assistance from other jurisdictions Interstate Assistance Given the physical isolation of Western Australia s electricity networks, assistance from other jurisdictions in relation to the disruption of electricity supply is likely to be limited to logistical support in exceptional circumstances. Australian Government Assistance The provision of Australian Government physical assistance is dependent upon established criteria and requesting arrangements. All requests for Australian Government physical assistance are to be made in accordance with SEMP Westplan Electricity Supply Disruption Page 17

18 Part 4 RESPONSE 4.1 Responsibility for response In compliance with regulation 23B of the Emergency Management Regulations 2006, the Coordinator of Energy is the HMA responsible for managing the response to an electricity supply disruption emergency. The HMA will determine the need to consult with, or assemble, the Operations Management Group (OMG) or the Operational Area Support Group (OASG) based on the nature of the incident. Network and System Operators are first responders to any electricity incident and remain the controlling agency for reparation / restoration of networks. 4.2 Notification System and Network Operators are responsible for notifying the HMA of a electricity supply disruption. Not all electricity supply incidents meet the requirement for HMA notification. The HMA has established the following indicators of a 'Notifiable Incident' with System Operators*. Figure 4 Notification Criteria Pre-emptive: Notification Reactive: Notification Hazards (Prescribed) A natural hazard likely to impact on key system infrastructure and/or large portion of the community, or A man made hazard that, either directly or indirectly, is likely to disrupt the effective operating of a supply system; and An Emergency Management Team (or equivalent) is convened and emergency preparations commenced System Risk Performance of key asset(s) altering the fundamental risk profile of the system or portion of the system, or Excessive demand day(s) where supply will not meet demand, or Potential market failure(s) arise; and Alterative arrangements and/or estimated reparation times do not negate risk Supply Disruption Key supply system asset(s) are impacted, or will be impacted Key State assets are impacted High media or political interest; and An Emergency Management Team (or equivalent) is convened and emergency preparations have commenced * System Operators have included this Notification process into their respective emergency management plans. The impacted operator is to include the following information when notifying the Public Utilities Office: The nature, location and time of the incident The impact to the supply system Total number of customers, "at risk" customers and essential services/infrastructure affected Strategies implemented for return to normal operations The HMA is responsible for notifying (as required) the: Office of the Minister for Energy Key stakeholders Westplan Electricity Supply Disruption Page 18

19 The State Emergency Coordinator 4.3 Levels of Response Alert Warning System The colour-coded Alert Warning System enables a consistent approach to assessing the severity of electricity supply disruptions ensuring an appropriate level of readiness and response. The Alert Warning System aligns with SEMP 4.1 whilst reflecting the difference between responding to traditional hazards and electricity supply disruptions. To support the assessment of the severity of an incident, the HMA will evaluate the impact (actual or probable) against the Core State Objectives. Core State Objectives The State Emergency Management Committee has defined the Core State Objectives as: People: Protect the lives and well-being of persons. Economy: Maintain and grow the State s productive capacity, employment and government revenue. Social: Ensure that there is public order, that people are housed and fed in a safe and sanitary manner and have access to social amenity including education and health services, and those things of cultural importance are preserved. Government: Ensure that there is, at all times, an effective and functioning system of government and societal respect for rule of law. Infrastructure: Maintain the functionality of infrastructure, particularly key transport infrastructure and utilities required for community health, economic production and effective management of emergencies. Environment: Protect ecosystems and biodiversity. While all objectives are considered, for the purpose of facilitating a more effective assessment of the severity, the objectives of People, Economy, Social and Infrastructure, are the higher risk considerations. At times there will be some overlap between the alert levels; the Operational Area Manager has the authority to determine the alert level based on the actual and/or potential impact of the incident. Satisfying one or more of the Indicators does not automatically necessitate an escalation to the level. The Indicators are provided for consideration and guidance only. Four levels to an incident have been established. Heightened Risk: Acute Supply Disruption High Risk: Acute Supply Disruption Acute Supply Disruption Critical Supply Disruption Acute Supply Disruption vs Critical Supply Disruption The only discernible difference between an 'acute supply disruption' and a 'critical supply disruption' is the length of the outage and the corresponding effectiveness of existing market mitigation strategies. A 'critical supply disruption' is that point when the effects to the market exceed existing control strategies and directly impact on the Core State Objectives - the response becomes primarily focused on consequence management. Westplan Electricity Supply Disruption Page 19

21 Red Level 3 Critical Supply Disruption Actual or imminent significant disruption to: o security of life and wellbeing o continuance of social integrity and necessary infrastructure o economy (State and/or region) Anticipated long term duration Extreme or actual threat to the health and safety of the community Loss (potential or actual) of contingency power supply to: o hospitals and clinics o correctional and policing facilities o water and waste water facilities Significant economic impact (either): o local community / government o State Requirement for total coordination of resources, actions and emergency management agencies A State of Emergency exists 4.4 Government / Market Coordination As indicated by the Alert Warning System a response to an electricity supply disruption escalates with the increasing severity and impending duration of the incident. Where possible Government intervention is avoided, preferring to allow existing market arrangements and supply channels to take effect. However the more serious an incident, the more Government involvement is required. Likely actions undertaken during a response are: Figure 6 Increasing Control Structure Industry / Market Emergency management arrangements (policies & plans) Market forces Emergency management policies & plans Internal redundancies & resupply strategies Inter organisational support policies Market forces Emergency management policies & plans Internal redundancies & resupply strategies Inter organisational support policies Emergency legislation under industry legislation Emergency management policies & plans Emergency legislation under industry legislation Established Emergency Response Arrangements HMA / Government No coordinated response between the HMA and market participants Minor HMA coordination of information Provision of advice to the Minister for Energy Increased control structure implemented Major HMA coordination of information Minor coordination of resources Provision of advice to the Minister(s) (Energy and Essential Services) Declaration of emergency situation Full control by HMA Significant coordination of information & resources Declaration of a State of Emergency Emergency regulations Network Operators have established a robust set of emergency management arrangements. These arrangements are activated either in anticipation of an emergency, or in direct response. Incident Escalation Westplan Electricity Supply Disruption Page 21

22 4.4.2 The Use of Market Mechanisms Network and System Operators, large users and market operators have a number of tools at their disposal to mitigate the incident. These can take the form of: market rules asset utilisation strategies demand restraint temporary system reconfiguration industry legislation Business Continuity Plans Businesses, essential service providers and government agencies follow established risk management principles. During supply outages it is expected that in the majority of short term instances business continuity / emergency response plans enacted will be sufficient to mitigate the more severe consequences of a disruption Legislative Intervention Legislative intervention is intended to be used when existing strategies are insufficient to mitigate the effects to the community. The legislation will be used to deliver a coordinated approach to the distribution of resources and implementing remedial strategies. The legislative instruments available in the response to a supply disruption are located in: Energy Operators (Powers) Act 1979 Emergency Management Act 2005 Fuel, Energy and Power Resources Act 1972 Declaration of System Emergency (Energy Operators (Powers) Act 1979) The emergency powers under the Energy Operators (Powers) Act 1979 constitute the principal statutory mechanism to respond to severe (actual or potential) threats to a distribution network. The powers, specific to the management of the supply system, enable both the system operator and the Minister for Energy to take measures to prevent a system failure. Declaration of Emergency Situation (Emergency Management Act 2005) When there is an identified need to access extraordinary emergency powers available within Part 6 of the Emergency Management Act 2005 the HMA, or the State Emergency Coordinator (or appropriate delegate), can consider the need to make an Emergency Situation Declaration. Declaration of a State of Emergency (Emergency Management Act 2005) The declaration of a State of Emergency by the Minister for Emergency Services, empowers the State Emergency Coordinator to authorise officers to take the same Part 6 actions as those available to the HMA, as well as further specified powers. A full list is available in the Emergency Management Act Declaration of a State of Emergency (Fuel, Energy & Power Resources Act 1972) The Governor of Western Australia may declare a State of Emergency and delegate responsibilities to the Minister for Energy. Upon the declaration of a State of Emergency, the State is able to draft emergency regulations to treat the consequences an emergency would have on the community. These regulations provide for the management of resources that best serve the needs of the community during the time of crisis. Westplan Electricity Supply Disruption Page 22

23 This Act takes precedence 13 over other legislation and is very broad in scope. The emergency regulations are therefore suited to both controlling consumption of electricity and also managing the flow on effects where there may be a need to control the supply of resources within the State. 4.5 Activation of Response Arrangements The response arrangements within Westplan Electricity Supply Disruption are activated on the commencement of a notifiable incident. The HMA, in consultation with relevant stakeholders, will assess the severity of the electricity supply disruption incident to determine its alert status and facilitate an appropriate level of response. 4.6 Incident Management System The HMA has reflected aspects of the Australasian Inter-Service Incident Management System (AIIMS) to ensure a level of consistency with other emergency management agency operations. The resources of the HMA, its reliance on outside industry experts to constitute part of the HMA, and its specific approach in response to an incident are all factors in determining the structure / system of the HMA. 4.7 Hazard Management Structure The following sections describe the incident management structure at the HMA level and at the State level, in line with SEMP Hazard Management Agency Structure Figure 7 HMA Structure Hazard Management Agency Coordinator of Energy Operational Area Manager Public Information Operations Team Planning Team Logistics Team Team Operations Management Group Operational Area Manager The Operational Area Manager is responsible for the overall management, provision of strategic direction and operational coordination of agencies during an emergency. In the discharging of their duties the Operational Area Manager will liaise closely with the Coordinator of Energy to ensure all strategies meet both the responsibilities of the HMA and the expectations of Government. 13 Fuel, Energy & Power Resources Act 1972 part III section 41 (1) Westplan Electricity Supply Disruption Page 23

24 Operations Management Group The Operations Management Group provides the operational response to an emergency. The structure consists of several teams that provide varying expertise and functionality to the HMA in the mitigation of an emergency. Operations Team o The Operations Team provides administrative and technical support to the Operations Management Group. Planning Team o The Planning Team is the principle group responsible for developing and implementing strategies to combat an electricity supply disruption. It consists of industry and Government representatives. Public Information Team o The Public Information Team works to develop, implement and monitor an integrated public information campaign. Logistics Team o The Logistics Team provides general support for the response teams while ensuring compliance with relevant legislation and government policies State Level Structure Figure 8 Increasing State Structure In the event of a State-level emergency, the HMA has access to additional assistance and resources via the: Operational Area Support Group State Emergency Coordination Group Westplan Electricity Supply Disruption Page 24

25 State Disaster Council State Recovery Coordinator Operational Area Support Group Supports the work of the OMG by providing agency specific information, expert advice and support in relation to the strategic and operational management of an incident. The group has a specific focus on the impact to the community, essential services and the economy. The HMA will activate the group as per the HMA's Operations Plan. State Emergency Coordination Group (SECG) In the event that an additional level of coordination is needed beyond the HMA structure, the HMA may seek establishment of the SECG in consultation with the State Emergency Coordinator. The SECG is tasked with ensuring an effective control structure has been implemented, and the level of coordination, provision of information and advice is sufficient to facilitate an effective response to an emergency. The SECG also serves as a liaison between the Minster for Emergency Services and emergency management agencies. Activation of the SECG is via the Executive Officer State Emergency Coordination Group 14. State Disaster Council The State Disaster Council is established if a State of Emergency is declared under the Emergency Management Act Chaired by the Premier, the State Disaster Council functions to provide prompt and accurate advice to the State Government and the SECG in relation to the state of emergency, liaise with the Australian Government for additional resources and support, and perform any other functions as directed by the Premier 15. State Recovery Coordinator (SRCO) & State Recovery Controller (SRC) The SRCO is responsible for the whole of government approach to recovery preparation and supports recovery through the activation of the State Recovery Coordination Group. If extraordinary arrangements are required to assist in the recovery of an emergency, the State Recovery Coordinator can recommend that the Premier appoint a State Recovery Controller 16. This position is responsible for ensuring the State provides a coordinated approach to recovery in emergency-affected communities. 4.8 Evacuation Arrangements Severe outages occurring in densely populated areas, such as Perth s Central Business District, may necessitate the need for the orderly dispersal of large numbers of people. In considering the need for an evacuation the HMA will consult with Western Australia Police, Main Roads Western Australia and the applicable local government. SEMP 4.7 and the Western Australia Community Evacuation in Emergencies guidelines, details the principles and protocols for conducting an evacuation in Western Australia. Nothing within the Westplan derogates from other emergency management agencies' ability to call for an evacuation where the life and safety of persons are under threat. 14 Operating Procedure 11 SECG Activation (WA Police) 15 Emergency Management Act 2005 Part 5 Division 3 16 SEMP Recovery Coordination Westplan Electricity Supply Disruption Page 25

26 4.9 Remote Community Arrangements The HMA considers that the Alert Warning System adequately captures the circumstances in remote communities. However, in assessing the explicit impact on the Core State Objectives, the HMA will be mindful of the intrinsic risk faced by remote communities and the current service levels afforded. The HMA will work with the Department of Housing, remote service providers and Network Operators to facilitate return of service. Endemic outages and essential service disruptions do not automatically constitute an emergency or require a response by the HMA Functional Support Plans Evacuation Plans Local Government (Various) Disaster Recovery Operational Site Emergency Response Plans (Various) Operations Plan: Electricity 4.11 Public Information and Media Management Provision of information to the public is a key element in the response to a supply disruption. It enables the community to assess their vulnerabilities, be informed and remain in-touch with the response. Good media management is a tool to support HMA strategies in combating the social flow-on effects of a supply disruption. SEMP 4.6 details the responsibilities and requirements for emergency management agencies in providing information to communities at risk Media Management Strategy Figure 9 Increasing Public Information Coordination White Public information and requests for information are directed to, and handled by, the affected market participants. Green Amber Red HMA coordination and oversight of consistent messaging, however, public information and requests for information are directed to, and handled by, the affected market participants. Public information and requests for information are coordinated by the HMA and affected market participants. A lead agency will be determined to act as the central communication point for the response. Public information and requests for information are directed solely to the HMA. The HMA in concert with the OMG and electricity industry will develop a coordinated statement. All media / emergency public information resources available to the HMA will be utilised. Where possible, the HMA considers that affected industry participants are the most appropriate body for the release of information specific to their business. Network operators have dedicated media liaison teams and customer service representatives. The public is encouraged to contact their retailer or network provider in the first instance when concerned with the provision of electricity. 24 hour emergency phone numbers are: Westplan Electricity Supply Disruption Page 26

Public information provision will be coordinated through the HMA s Public information Team Release Methods The development of any Emergency Public Information will take into consideration the probable loss of broadcast and/or web media when developing a release strategy Westplan Emergency Public Information In the event the incident escalates beyond the resources of the HMA to adequately undertake the public information function, or where assistance is required, the State Emergency Public Information Coordinator (in consultation with the State Emergency Coordinator and the SECG) can activate Westplan Emergency Public Information at the State level Activation of Other Westplans in Support of This Plan Westplan Electricity Supply Disruption (this plan) may be enacted in conjunction with: Westplan Cyclone Westplan Storm Westplan Fire Westplan Flood Westplan Earthquake Westplan Heatwave Westplan Gas Supply Disruption Westplan Terrorist Act Westplan Recovery Coordination Westplan Welfare Westplan Telecommunications Westplan Emergency Public Information In the event of the activation of any other Westplan, the designated HMA under that plan will be responsible for the prevention, preparedness, response and recovery elements contained within its scope Westplan(s) Gas Supply Disruption, Liquid Fuel Supply Disruption The Coordinator of Energy is the HMA for gas and liquid fuel supply disruptions 17. In the event that the supply disruption coincides with, or is the result of, a severely constrained gas or liquid fuel market, the corresponding Westplan for gas or liquid fuels will be activated and run concurrently with this Westplan. The HMA will convene separate Operations Management Groups and assess the best practice for disseminating information between the groups. Operational particulars have been considered in the HMA's Operations Plan: Electricity. 17 Emergency Management Regulations 2006 regulation 23B Westplan Electricity Supply Disruption Page 27

28 Westplan(s) Cyclone, Storm, Bush Fire, Flood Natural weather events pose a significant risk to electricity networks. The Fire and Emergency Services Commissioner is the HMA for the natural hazards of storm, cyclone, fire and flood 18. Where an incident has escalated to a multi-hazard response, the HMA s will work collaboratively, per SEMP 4.1. Operational particulars have been considered in the HMA's Operations Plan: Electricity Westplan - Heatwave Heatwaves put significant stress on the electricity network as extreme heat interferes with efficient distribution & transmission, and consumers offset discomfort by turning to air conditioning units. These days usually result in peak electricity demand days. The State Health Coordinator is the HMA for heatwave 19. In the event a heatwave corresponds with an electricity supply disruption, the HMAs will work collaboratively to provide a coordinated response to the incidents Financial Arrangements for Response Financial arrangements for the funding of emergencies are detailed in SEMP 4.2. Generally, to ensure accountability for expenditure incurred, the organisation with operational control of any resource shall be responsible for payment of all related expenses associated with its operation during emergencies unless other arrangements are established (subject to criteria) Terminology Used in This Part This Westplan uses some broad terms in defining what level an incident is. The objective is to afford decision making discretion to the Operational Area Manager where the indicators present do not necessarily fit within the perceived risk profile. Heightened Risk: No Discernible Effect: A fundamental change in the underlying risk profile of the electricity supply system not, or only partially, offset by implemented mitigation strategies. The effect is not sufficient to cause undue stress on the operations of the State and the community. High Risk: Minor Effect: Acute Supply Disruption: Critical Supply Disruption: The supply system has entered a period of risk whereby additional strain placed upon the system may result in an acute supply disruption. The effect is sufficient for the implementation of emergency plans and uptake of established mitigation strategies. In the main, all strategies are offsetting the increase in operational risk. Either widespread or localised, however the areas affected contain key State infrastructure assets. The length of time is not expected to be of significant length and existing mitigation strategies are in the main sufficient to meet the short term operational risk. Mitigation strategies are insufficient and the State is either experiencing or about to experience a significant degradation to the infrastructure / 18 Emergency Management Regulations 2006 regulation Emergency Management Regulations 2006 regulation 22 Westplan Electricity Supply Disruption Page 28

30 Part 5 RECOVERY Recovery management is the coordinated process of supporting emergency affected communities in the reconstruction of physical infrastructure and the restoration of emotional, social, economic and physical well-being. 5.1 Responsibility for Recovery Under the Emergency Management Act 2005 it is a function of local government to manage recovery following an emergency affecting the community in its district. The extent of recovery activity will depend on the nature and magnitude of the emergency. In some circumstances it may be necessary for the State Government to assume responsibility for coordinating the recovery process at a whole-of-government level. The HMA must initiate recovery during the response to that emergency. Westplan Recovery Coordination and SEMP 4.4 Recovery Coordination describe in further detail the strategic arrangements and responsibilities for recovery. Part 6 Stand Down and Debriefs 6.1 Stand Down and Debriefs The Operations Management Group is stood down by the Operational Area Manager or nominated representative. This may occur when the impacts of the electricity supply disruption have been largely addressed through a range of mitigation measures, or when the Operations Management Group can take no further action to provide support to Government or industry. The Operations Area Manager will promptly advise the Operations Management Group of any subsequent change to the response level until the alert status returns to normal market conditions. The HMA will assume responsibility for coordinating a formal multi-agency debrief as soon as possible following a return to normal business. 6.2 Incident Analysis / Review When the incident is over the HMA will ensure that all records, information and logs are collected and securely stored. For incidents that have been declared a Level 2 (Amber Alert Level) or Level 3 (Red Alert Level) the HMA, in conjunction with the Operations Management Group, will arrange for a review of the incident to be held to determine: the nature of the incident and its consequences the effectiveness of the Action Plan implemented to respond to the electricity supply disruption the effectiveness of the incident management procedures in the HMA's Operations Plan: Electricity, and the Operations Management Group the effectiveness of the public information campaign recommendations as appropriate regarding changes to arrangements to better manage future electricity supply disruption events. In compliance with SEMP 4.3, the HMA will provide a post-operations report on the incident to the SEMC. Westplan Electricity Supply Disruption Page 30
