Power Grid Cybersecurity Market Size, Share & Growth Forecast (2026-2031)

The Power Grid Cybersecurity Market is forecast to grow at a CAGR of 9.1%, reaching USD 5.35 billion in 2031 from USD 3.46 billion in 2026.

Utilities are required to layer protection onto generation assets, transmission networks, distribution systems, substations, control centers, and communication infrastructure as well as distributed energy resources, at the same time. Power-grid cybersecurity ranges from hardware and security solutions to cybersecurity software, monitoring platforms, managed services, vulnerability assessment, incident response, secure remote access, network segmentation, endpoint protection, identity management, threat intelligence, and security compliance.

The trend that can heavily influence the market is due to the convergence of information technology and operational technology. In addition, legacy power infrastructure was often built on isolated control systems and long asset lifecycles; however, modern grids rely more heavily on standardized communication protocols, connected sensors, cloud applications, remote access, and interoperable digital platforms.

Additionally, utilities are deploying security controls much closer to operational assets. For instance, Siemens identifies OT/ICS asset inventory, vulnerability-risk prioritization, secure remote access, continuous OT/ICS network monitoring, insider-threat detection, and incident response within its Noedra Shield grid cybersecurity framework.

Increased deployment of smart grids and digital substations is adding to the demand. Hence, a core challenge for the market ecosystem comes down to utilities needing to accelerate digital transformation; otherwise, they increase the odds that compromised digital systems can influence physical electricity operations.

Power Grid Cybersecurity Market Key Highlights

Market Dynamics

Market Drivers

• Increasing Digitalization of Electricity Grids: utilities are incorporating smart meters, intelligent protection systems, various types of sensors for remote monitoring, and connected grid-management platforms, from building digital substations to using automated distribution systems, to improve reliable and efficient operation. Digitalization is simultaneously highlighted by the IEA as increasing the efficiency of electricity systems and also raising cybersecurity threats.

• Expansion of Distributed Energy Resources: Distributed solar, battery storage, EV chargers, flexible loads, and other DERs alter the way in which electricity travels through distribution networks. Moreover, these resources are becoming progressively automated and administered from a distance. As per strategic planning material from NERC, DERs and distribution-side aggregators expand the current attack surface, and the threat landscape is expected to see an increase in threats from lone actors and state-sponsored hackers. This is encouraging utilities to deploy cybersecurity controls across DER communication systems, aggregation platforms, distribution-management systems, and other endpoints in the network.

• Cybersecurity Threat Landscape on Critical Infrastructure: Since power systems impact hospitals, transportation, telecommunications, financial institutions, industrial facilities, and households, electricity infrastructure continues to be a high-value target. North America experienced a steadily evolving threat landscape in 2025, with an increasing frequency of new threats never before seen in bulk power system security, including approximately 1,900 member and partner organizations receiving electricity-security information and risk-mitigation resources from NERC. It is therefore the growing sophistication of cyber threats that is forcing utilities to transition from reactive incident response to continuous monitoring, threat detection, vulnerability management, and resilience planning.

• Increasing Regulatory and Compliance Requirements: Power utilities are critical infrastructure operators who face sector-specific cybersecurity regulations. NERC CIP obligations for North American utilities and the growing number of international operators with other standards, including IEC 62443, IEC 62351, NIST, NIS2, and national cybersecurity framework standards. GE Vernova includes its support for compliance with NERC CIP, NESA IAS, and the EU NIS Directive for grid cybersecurity solutions, while its grid offerings have also been certified to IEC 62443-2-4 and IEC 62443-3-3. This is increasing the recurring demand for services in areas such as cybersecurity assessment & monitoring, compliance reporting, vulnerability management, and managed security.

Market Restraints & Opportunities

• Power infrastructure often has an operational life of decades, so new digital systems must work alongside older equipment that could not have been designed to connect to a network because it did not exist at the time. The IEA stated that since electricity infrastructure can be in use for over 50 years, this will lead to combinations of modern digital devices and legacy assets.

• Migrating legacy equipment solely for cybersecurity reasons is expensive and operationally disruptive. As such, utilities increasingly need compensating controls, including network segmentation, secure gateways, monitoring solutions that are resilient, patch management at the virtual level, and controlled remote access.

• OT cybersecurity domains are developing managed services, cybersecurity assessments, vulnerability management, incident-response programs, continuous monitoring, and security operations centers in response to the lack of specialized OT cybersecurity expertise.

• Rising grid telemetry and cybersecurity event volumes are presenting analytical opportunities to augment threat detection with AI.

Key Developments

• May 2026: The Pacific Northwest National Laboratory inaugurated its EVE@PNNL, i.e., Enhanced Visibility and Event Response capability, to bolster U.S. energy security. This model initially functioned in a grid-control-room-like environment, leveraging AI-driven analytics paired with advanced sensing and real-world simulation, and used adaptive controls, anomaly detection, autonomous reconfiguration, and controlled islanding.

• March 2026: Cybersecurity-monitoring demonstration launched at a Japanese grid-scale battery-energy-storage facility by Panasonic Holdings, its subsidiary Panasonic Solution Technologies, and ITOCHU. For this trial, they implemented both signature detection of known attacks and some elements of behaviour profiler analysis designed for energy-management and power-control communications.

Market Segmentation

The market is segmented by component, security type,application, end user, and geography.

By Component: Hardware & Solutions

The Hardware & Solutions component category was one of the largest, as cybersecurity must increasingly be embedded directly within the physical and communication infrastructure that connects grid assets.

This segment consists of purpose-built dedicated security infrastructure, such as industrial firewalls, secure gateway network-security appliances, intrusion-detection systems, secure routers and endpoint-security appliances as access-control devices, substation cybersecurity equipment, and other devices.

Power grids with availability and deterministic performance as critical demands require security architectures that must also work within the context of higher-order flow factors in order to preserve their ability to deliver on-demand services at low latencies. The Schneider grid cybersecurity strategy includes secure connected products, IEC 62351 role-based access control (RBAC), and IEC 62443-based OT security.

Additionally, the segment is progressing toward integrated OT security appliances that merge network segmentation, secure remote access, threat detection, and industrial-protocol visibility into one box versus needing separate solutions like traditional IT firewalls.

By Security Type: Network Security

Network Security segmentation is one of the prominent security domains, as power systems are even more value-dependent on the integrated communication system interconnecting substation–control centers– protection devices and SCADA/field equipment and distributed energy resources.

Network-security solutions include segmentation, secure communication in various types of tunnels, access control, traffic monitoring, intrusion detection and prevention, secure remote access, and threat-detection functions for IT-OT integrated environments.

Schneider Electric cites the growing need for cybersecurity as control systems have become more open and interconnected, with communication networks being vulnerable and legacy systems potentially threatening grid reliability. Similarly, Siemens also offers OT/ICS network monitoring and secure remote access with Noedra Shield architecture.

The segment is growing with utilities embracing zero-trust philosophies, network segmentation, encrypted communications methods, identity-based access controls, and continuous monitoring to help contain any breach from spilling over into critical operational systems and finances.

By Application: Substantial Automation & Security

Substation Automation & Security is a significant application area because of the modernization trends that include intelligent electronic devices, digital protection systems, SCADA automated control, and communication networks with remote-access capabilities at modern substations.

Further, digital substations provide better operational visibility and automation; however, with that comes increased reliance on software, communication protocols, and connected devices.

Siemens is a provider of grid security solutions that address product security, system security, operational security, patch management, asset management, and SIEM-based monitoring for substations. Other components of Siemens' grid-security portfolio include SIPROTEC and SICAM security updates.

Hitachi Energy integrates cybersecurity into its grid automation products and systems through security-development processes, threat modeling, security design reviews, individual user accounts, event logging, and security testing.

The segment has transitioned from perimeter protection to security-by-design across intelligent substations, where asset visibility, authentication, monitoring, secure engineering, vulnerability management, and incident response become core components of substation modernization.
