Robotics for electricity generation, transmission and distribution systems – Part 1-2: State-of-the art and standardization roadmap for electric power system robots

This technical report represents a foundational step toward shaping the way robots are introduced, deployed, and standardized in the electric power industry. IEC TR 63439-1-2:2026 provides a sweeping overview, from operational scenarios to technology integration, and sets clear paths for the next generation of standards in the sector.

Scope and Structure

IEC TR 63439-1-2:2026 encompasses robotics throughout the power sector (generation, transmission, distribution), focusing on:

• System overview and classification: Robots are analyzed and categorized by scenarios (e.g., substations, power lines), roles (inspection, repair), and environmental contexts (high-voltage, confined spaces).
• Core technology assessment: Key technologies such as ground/mobile robots, drones, UAVs, navigation (GPS, LiDAR, vision), and secure communications are comprehensively evaluated.
• Testing and validation framework: The standard introduces benchmarks for performance (autonomous navigation, inspection accuracy), reliability (FMEA/FMECA approaches), and environmental resilience.
• Standardization roadmap: A systematic gap analysis of existing standards yields a phased plan for new requirements covering hardware, interfaces, safety, and compliance across stakeholders.

Key Requirements and Specifications

• Robotic Types and Classification: Differentiates between ground, aerial, and underwater robots, with operational distinctions based on function (inspection, maintenance, emergency response) and scenario (generation, substation, distribution).
• Functional Capabilities: Specifies multi-sensor approaches (visual, infrared, ultrasonic), advanced path planning, autonomous navigation, and human-machine collaboration models.
• Testing Methodologies: Introduces robust frameworks for operational benchmarks, including performance, reliability (environmental testing, failure mode analysis), and cybersecurity metrics.
• Data, Communication, and Security: Strong emphasis on interoperability, secure data transmission (wired, wireless, hybrid networks), integration with grid management and monitoring systems, data protocols, and risk management for cyber-physical systems.
• Standardization Priorities: Provides a stepwise policy for the development and adoption of international standards, facilitating harmonization and compliance verification from R&D, manufacturing, deployment to operations.

Who Must Comply

The standard’s relevance extends to:

• Electric utilities and independent power producers.
• Technology vendors (robotic platforms, AI, sensors, communication modules).
• Grid operators and system integrators.
• Health, safety, and compliance officers involved in high-voltage and critical infrastructure maintenance.
• Engineering and asset management teams responsible for power plant and substation operations.
• Professional associations and standardization bodies.

Practical Implications

Organizations will benefit from:

• Improved operational safety by reducing human exposure to high-voltage and hostile environments.
• Cost reductions through automating routine O&M (operation and maintenance) and inspection cycles.
• Enhanced grid stability, asset health monitoring, and emergency responsiveness.
• Support for rapid deployment and integration of new technologies through standardized testing and documentation practices.

Notable Changes Compared to Past Practice

• Establishment of a clear, internationally recognized taxonomy and benchmark framework for all major robot types and scenarios in power systems.
• Incorporation of advanced cybersecurity and data integrity provisions, reflecting industry digitization and IoT realities.
• Introduction of real-world use cases and validation procedures to accelerate interoperability and adoption worldwide.

Key highlights:

• Unified robot classification across applications and environments
• Benchmarks for inspection, reliability, and cybersecure operation
• Stepwise roadmap for standards development and industry compliance
