 Critical infrastructure refers to systems and assets whose disruption would significantly affect public safety, security, or economic continuity. Electricity grids sit at the core of this category — most other critical systems depend on them, and their growing complexity under smart grid transitions introduces new vulnerabilities alongside new capabilities.
 </WRAP>
 ===== Why this matters =====
-Electricity is the infrastructure that underlies most other critical infrastructure. Hospitals, water treatment, communications, and transport all depend on reliable power. As grids become more digitalised and distributed, the attack surface expands — cyberattacks, extreme weather events, and cascading failures across interconnected systems all pose risks that conventional grid design did not anticipate. Protecting electricity infrastructure is therefore not just a technical challenge but a governance one, requiring coordination across regulatory, operational, and security domains.<sup>1,2</sup>

-Digitalisation makes new forms of grid coordination possible — and introduces new vulnerabilities that did not exist in analogue systems.

+===== Shared definitions =====
-The EU Directive on the Resilience of Critical Entities (CER, 2022/2557) defines critical infrastructure as infrastructure essential to the maintenance of vital societal functions, economic activity, public health, safety, or security, whose disruption would have significant cross-sectoral effects. Energy — including electricity generation, transmission, and distribution — is explicitly listed as a critical sector.<sup>1</sup>

-Within that framework, electricity grids carry additional specificities: they are highly interconnected, failures can cascade across large geographic areas, and increasing digitalisation ties grid reliability to cybersecurity in ways that earlier regulatory frameworks did not address. The EU NIS2 Directive (2022/2555) responds to this by establishing binding cybersecurity obligations for energy operators as essential entities.<sup>2</sup>

 ===== Perspectives =====
-Critical infrastructure protection involves different roles and responsibilities depending on who you focus on, what systems are at stake, and what governance frameworks apply.

 <WRAP perspectives>
 ==== Actors and stakeholders ====
-Responsibility for critical infrastructure protection is distributed across multiple actors — grid operators, national regulators, cybersecurity agencies, emergency services, and government ministries — who rarely share a single chain of command. Coordination among them before, during, and after disruptions is as important as the technical measures each actor takes individually. In practice, information sharing across these groups remains uneven, and the boundary between operator responsibility and state responsibility is often contested.<sup>1</sup>

Implementation pace has varied considerably across the EU, with most member states missing the October 2024 transposition deadline.<sup>1</sup>

 ==== Technologies and infrastructure ====
-The interdependence of electricity grids with telecommunications, water, transport, and digital systems means that a failure in one can propagate across others. Smart grid technologies improve situational awareness and operational flexibility, but also expand the digital attack surface. Cybersecurity measures for operational technology — SCADA systems, distribution management platforms, smart meters — are increasingly treated as integral to grid design rather than as an add-on.<sup>2,3</sup>

 ==== Institutional structures ====
-Regulatory frameworks for critical infrastructure protection have traditionally focused on physical security. The growing digital dimension has prompted a shift toward integrated cyber-physical governance, but the institutional architecture — who regulates what, at which level — varies significantly across jurisdictions. Cross-border interdependencies add a further layer, as a disruption in one country's grid can affect neighbours sharing the same synchronous zone.<sup>1,3</sup>

+<WRAP distinction>
+**Critical infrastructure vs resilience**\\
+Resilience describes a system's capacity to absorb, adapt to, and recover from disruptions; critical infrastructure protection is the governance and technical effort to maintain that capacity in systems whose failure would have cascading societal effects. The two concepts are closely related — resilience is the goal, critical infrastructure protection is the practice — but they belong to different analytical frames. See the [[topics:resilience|Resilience]] topic.
+</WRAP>
+<WRAP distinction>
+**Physical security vs cybersecurity**\\
+Conventional critical infrastructure protection focused on physical threats — natural disasters, sabotage, physical attack. Digitalisation adds a distinct attack vector: cyber intrusions targeting operational technology can cause physical effects without any physical access. Current frameworks (NIS2, CER) treat these as complementary rather than separate, but operational integration across the two domains remains uneven.

+@@GAP@@ Non-EU case needed: add a case showing how critical infrastructure governance is structured in a non-European context (e.g. US NERC CIP standards, or a national framework in Asia or Latin America).
+@@GAP@@ Both non-EU case gaps noted in Perspectives need filling before in-review status.
