CIGRE | Paris Session 2026
Hitachi Energy is driving the development of a secure, affordable, and sustainable power system, enabling the era of electrification through abundant and affordable electricity that underpins society. We are empowering societies to thrive and securing growth for the next generation. Today for us. Tomorrow for them.
As the world accelerates toward electrification, the need for resilient, flexible, reliable, and cyber-aware grid technologies has never been greater. At CIGRE 2026, we are showcasing the innovations that help strengthen energy security, improve efficiency, and securely integrate renewables at scale.
Why CIGRE 2026 matters
The technology exists. Delivery is the bottleneck.
We’ve entered the Electricity Era. Demand is rising as transport, industry, buildings and digital infrastructure electrify — but the grid’s ability to scale is now the constraint. The pioneering technologies are proven. The priority is deployment: building, modernizing and operating a system that stays secure, affordable and sustainable as it grows more complex.

MAIN THEMES
One balance the system must strike
Affordability
Affordability begins with the design and efficiency of physical equipment. We help utilities do more with existing assets, for longer — optimizing total cost of ownership across the full asset lifecycle.
Security
Energy security starts at the physical layer and is reinforced by automation and intelligence. We strengthen it with resilient, flexible, reliable and cyber-aware grid technologies.
Sustainability
Sustainability means decarbonizing the grid itself while integrating renewables at scale — from SF₆-free, eco-efficient equipment to digitally optimized operations.
OUR DIFFERENTIATOR
We don’t sell parts. We deliver one integrated system.
Physical infrastructure
The foundation
The assets that carry high-voltage power safely and reliably.
EconiQ SF₆-free switchgear · HVDC DC circuit breaker · transformers · C-LVR · FACTS · Air RIP Flex 800 kV
Automation & protection
Unlocks it in real time
Fast, selective, cyber-secure protection and control that lets the infrastructure perform under stress.
Relion 670 series · REF650 · SAM600 · FOX615 · NSD670 · MicroSCADA X
Enterprise intelligence
Maximizes its value
Run the grid in real time and optimize asset and work performance across the lifecycle - turning data into insights.
HMAX Energy · Network Manager · Asset & Work Management
One architecture, across the full grid lifecycle — from planning and construction to operation, maintenance and lifetime extension.
