Company Background and Stakeholders Analysis
Western Power is a state-owned enterprise that operates in Western Australia (WA). Established in 2006 under the Electricity Corporation Act 2005 (Government of Western Australia, 2005). As a government-owned enterprise, Western Power is accountable to the State Government of WA and operates under the supervision of the Minister for Energy (Western Power, 2022).
Western Power has a structured organisation consisting of seven distinct business units. Each of these units is led by an Executive Manager and is further composed of several Heads of Function. These roles collectively operate under the overarching leadership of the Chief Executive (Western Power, 2022).
Western Power is responsible for constructing, up-keeping, and overseeing the electrical infrastructure in the Southwest Interconnect System (SWIS) area that covers a range of approximately 255,000 square kilometres, reaching from Perth to Albany in the south, Kalgoorlie in the east, and Kalbarri in the north, making Western Power the principal licenced distributor in the state (Australian Energy Council, 2018).
Their main goal is to ensure the proper functioning of their distribution network to supply energy continuously to well over 2 million customers, which are heavily relying on their operations and success (Western Power, 2023).
Western Power Stakeholders Analysis
Western Power engages with a diverse array of stakeholders, each with distinct interests and expectations (Western Power, 2022, p. 11). An analysis of these stakeholders can reveal their significance and influence on Western Power’s operations and decisions (Smith, 2000).
Identification
The Minister for Energy, serving as Western Power’s exclusive owner and shareholder, maintains control over the organisation (Western Power, 2022, p. 88). Simultaneously, customers hold a central position in Western Power’s operations. Residential, commercial, and industrial consumers rely on a continuous and reliable electricity supply. Their feedback and demands influence service quality, rates, and energy efficiency initiatives (Deloitte, 2016, p. 8).
Likewise, the communities served by Western Power possess a vested interest in uninterrupted electricity supply. Community sentiment, expectations regarding sustainable energy practices, and concerns about infrastructure impact collectively shape the company’s relationship with the public (Western Power, 2022, p. 7).
Conversely, mining companies, manufacturers, and businesses emerge as critical stakeholders. Their dependence on an uninterrupted power supply drives their collaboration with Western Power to ensure operational continuity and competitiveness (Western Power, 2022, p. 7). In fact, Western Power could decide to source energy to critical entities such as The Water Corporation directly.
Moreover, Western Power’s workforce plays a fundamental role in its day-to-day operations. Additionally, hospitals, transportation systems, and emergency services rely on reliable power supply. Western Power’s responsibility for fulfilling the energy needs of critical infrastructure profoundly impacts public safety and the provision of essential services.
Furthermore, equipment, technology, and service suppliers contribute significantly to Western Power’s operations. Effective partnerships with suppliers and contractors considerably influence service reliability and innovation (Western Power, 2021).
Additionally, stakeholders focused on environmental sustainability advocate for responsible energy practices and the integration of renewable energy sources. Their perspectives wield influence over Western Power’s endeavours to balance energy needs with environmental considerations (Western Power, 2018).

| Workforce / Employees | 2 | 4 | Keep informed |
| Critical Infrastructure (hospitals, transport) | 2 | 4 | Keep informed |
| Environmental Advocacy Groups | 2 | 3 | Monitor |
| General Public | 1 | 2 | Monitor |
Power & Interest Grid
The Power & Interest Grid categorises stakeholders into four quadrants:
- Manage Closely (High Power / High Interest): Minister for Energy: primary decision-maker with full oversight
- Keep Satisfied (High Power / Low Interest): Suppliers, industrial customers: critical for operations, engaged on specific issues
- Keep Informed (Low Power / High Interest): Workforce, communities, critical infrastructure: directly affected, require regular communication
- Monitor (Low Power / Low Interest): General public, environmental groups: secondary stakeholders requiring periodic engagement
Summary
The stakeholder analysis reveals that Western Power operates within a complex ecosystem of interdependencies. The Minister for Energy, as sole shareholder, exercises ultimate governance authority. However, the operational continuity of the organisation depends critically on the satisfaction of customers, the reliability of suppliers, and the safety of the communities it serves. This creates a governance environment in which information security is not merely a technical concern but a strategic imperative.
Western Power manages a broad and sensitive portfolio of information assets. These can be categorised into four primary domains:
Operational Technology (OT) Data:
- SCADA (Supervisory Control and Data Acquisition) system data governing power grid operations
- Distribution Management System (DMS) data
- Real-time network telemetry from substations, transformers, and switching equipment
- Smart meter data from residential and commercial customers
Customer Information:
- Customer personal information (names, addresses, contact details)
- Energy consumption data and billing records
- Payment information
- Contractual agreements and service records
Corporate Information:
- Financial records and reporting
- Human resources and employee data
- Strategic plans and procurement information
- Contracts with third-party vendors and government agencies
Regulatory and Compliance Information:
- Licence documentation under the Electricity Corporations Act 2005
- Compliance reports submitted to the Economic Regulation Authority (ERA)
- Environmental and safety compliance records
Information flows within Western Power can be characterised along two primary axes:
Operational Information Flow: Real-time data from the SWIS grid flows from field devices through SCADA systems to the Energy Management System (EMS), enabling centralized monitoring and control. This operational technology (OT) environment must be isolated from the corporate IT network to prevent lateral movement in the event of a cyberattack.
Corporate Information Flow: Business data flows from field operations through enterprise resource planning (ERP) systems to executive reporting, regulatory submissions, and external stakeholders. This includes customer billing, asset management records, and financial reporting to the WA Government.
Information assets are prioritised based on three factors:
- Criticality to Operations: SCADA and grid control data are the most critical; their compromise or disruption could directly affect power supply to 2 million customers
- Regulatory Obligation: Customer personal information and regulatory compliance records carry significant legal obligations under the Privacy Act 1988 and sector-specific regulations
- Commercial Sensitivity: Financial forecasts, procurement strategies, and vendor contracts carry commercial sensitivity that could be exploited by competitors or bad actors
Threat Analysis and Recommendations
Threat 1 – Cyberattacks
Description: Western Power, as a critical infrastructure operator, represents a high-value target for both nation-state threat actors and financially motivated cybercriminals. The potential consequences of a successful cyberattack extend far beyond Western Power itself; a disruption to the SWIS power grid could affect hospitals, water treatment facilities, transport networks, and millions of Western Australian residents.
Key Attack Vectors:
Ransomware: Ransomware gangs increasingly target critical infrastructure. A successful ransomware deployment targeting Western Power’s corporate IT systems could encrypt billing systems, customer records, and operational databases, causing service disruption and significant financial losses.
OT/SCADA Intrusion: The most severe scenario involves adversaries breaching the operational technology environment. Malware such as Industroyer (used against Ukrainian power infrastructure in 2016) demonstrates that threat actors have the capability to interfere with industrial control systems, potentially causing physical damage to grid equipment or triggering widespread outages.
Phishing and Social Engineering: As demonstrated by the Scattered Spider attacks on MGM and Caesars, social engineering remains highly effective. Employees with access to sensitive systems may be targeted through spear-phishing emails, SMS phishing, or voice phishing (vishing) attacks designed to harvest credentials.
Risk Level: High, owing to the combination of high-value target profile, expanding digital attack surface (smart meters, cloud integration), and potential for cascading societal impact.
Threat 2 – Insiders
Description: Insider threats, whether malicious, negligent, or compromised, represent a persistent and difficult-to-detect risk for any large organisation. Western Power’s distributed workforce, including contractors and third-party vendors with system access, amplifies this risk.
Categories of Insider Threat:
Malicious Insiders: Employees or contractors who deliberately misuse their access for financial gain, sabotage, or espionage. This includes individuals who may be recruited by external threat actors or who act on personal grievances.
Negligent Insiders: Staff who inadvertently create security risks through careless behaviour, such as falling victim to phishing attacks, using weak passwords, sharing credentials, or connecting unauthorised devices to corporate networks.
Compromised Insiders: Legitimate employees whose credentials have been stolen by external attackers, who then operate within the organisation under the guise of a trusted identity.
Risk Indicators:
- Unusual system access outside of business hours
- Large file downloads or data transfers to external media
- Repeated failed login attempts followed by successful access
- Accessing systems or data outside the scope of normal role requirements
Risk Level: Medium-High, difficult to detect, can bypass perimeter controls, and may have access to both IT and OT environments.
Threat 3 – Climate Change
Description: Western Australia is increasingly exposed to the impacts of climate change, including extreme heat events, bushfires, severe storms, and flooding. As the operator of critical electrical infrastructure across 255,000 km², Western Power faces significant physical risks to its assets and operational continuity.
Climate-Related Security Risks:
Physical Infrastructure Damage: Extreme weather events can damage transmission towers, substations, and distribution lines, causing outages that cannot be rapidly remediated. The January 2022 storm event in Perth caused widespread outages affecting hundreds of thousands of customers.
Increased Demand Spikes: Prolonged heatwaves drive extreme peak demand events, stressing the grid and increasing the risk of cascading failures. This creates pressure on control systems and may expose vulnerabilities when systems operate at or near capacity.
Indirect Cyber Risk: Emergency response and recovery periods create windows of elevated cybersecurity risk. Staff focus on restoration rather than security monitoring, incident response procedures may be deprioritised, and emergency remote access may be extended without adequate security controls.

Supply Chain Disruption: Climate-related disruptions to supply chains can affect the availability of critical spare parts and equipment, extending recovery times following physical infrastructure damage.
Risk Level: Medium and growing; climate risk intersects with cybersecurity and operational risk in ways that require integrated planning.
Information security is not a peripheral concern for Western Power; it is foundational to the organisation’s ability to fulfil its core mission of reliable energy delivery.
The consequences of information security failures for Western Power are uniquely severe:
Operational Continuity: Disruption to SCADA or energy management systems can directly cause power outages affecting millions of customers. Unlike a retail data breach, a grid disruption has immediate and potentially life-threatening consequences for hospitals, emergency services, and vulnerable residents dependent on electrically powered medical equipment.
Regulatory Compliance: Western Power operates under a complex regulatory framework. Failure to protect customer data creates exposure under the Privacy Act 1988, while failures in OT security may attract scrutiny from the Australian Energy Market Operator (AEMO) and the Australian Cyber Security Centre (ACSC).
National Security Implications: Critical infrastructure attacks are increasingly viewed as acts of geopolitical aggression. The Australian Government’s Security of Critical Infrastructure Act 2018 (amended 2021 and 2022) imposes specific obligations on electricity sector operators, including mandatory incident reporting and risk management program requirements.
Reputational and Financial Impact: A major cybersecurity incident would significantly damage public trust in Western Power’s ability to fulfil its obligations, creating political and financial consequences for the state-owned enterprise and its government shareholder.
