- WHY REGENERA®
The Grid Is Changing. So Must Its Technology.
The energy landscape is undergoing the most profound transformation in a century. Electrification is accelerating across every sector – from industry and mobility to homes, cities, and entire economies. At the same time, the rapid rise of digital infrastructure is reshaping global electricity demand. Data centers alone are becoming one of the world’s fastest-growing energy consumers, powering AI, cloud computing, and the digital services that now define modern life.
This shift is occurring in parallel with rising global climate challenges.
Traditional insulation materials for high voltage equipment – such as mineral oil, and gases like SF₆ – once seen as the unquestioned backbone of high-voltage systems, are now among the most significant barriers to decarbonization. For decades, they delivered reliability, but today their environmental impact and the operational risks associated with them can no longer be overlooked.
The challenge is clear: to continue powering progress without powering climate change. At Trench Group, we are turning that challenge into opportunity.
And this is where REGENERA® begins.
- WHAT IS REGENERA®
Built on One Principle:
Strong Performance, Cleaner by Design.
REGENERA® is Trench Group’s designation for products and services that meet defined criteria for technical performance and environmental responsibility across the asset lifecycle. The designation applies to products designed to reduce reliance on hazardous substances, incorporate lower-carbon materials and support circularity, while delivering the performance, reliability, and safety the grid demands.
It brings together dry-type and biodegradable insulation technologies with lifecycle services that keep assets efficient and reliable over a long operating life.
- SF₆-Free
- MINERAL OIL-Free
- BIODEGRADABLE FLUID
- The four pillars of REGENERA®
From Design to End of Life.
Design
Elimination of hazardous substances such as SF₆ and mineral oil; more recycled, recyclable and bio-based materials; designs that support circularity.
HOW WE ASSESS IT
Through the bill of materials – which substances have been eliminated, the share of recycled, recyclable and bio-based content, and whether the design supports disassembly and material recovery.
Performance
A long, proven operational lifetime, consistent reliability, and dependable performance under unusual service conditions.
HOW WE ASSESS IT
Safety
Reduced fire risk, safer handling, and enhanced environmental and human safety through responsible material choices and biodegradable* insulation options.
HOW WE ASSESS IT
Impact
Designs that reduce embodied emissions, minimize operational losses, and extend service life - supporting customer decarbonization and regulatory readiness.
HOW WE ASSESS IT
- PRODUCT PORTFOLIO
Built for Tomorrow's Grid.
Each REGENERA® line is engineered around cleaner insulation technology, without compromising performance.
Eco Fluid Line
- Biodegradable fluid
- Mineral-oil replacement
Our Eco Fluid line replaces mineral oil with biodegradable* fluids – lowering fire risk and reducing the impact of any leakage, without compromising performance.
- Oil-free
- Dry
- Up to 765 kV
- Low fire risk
Our Dry Insulation line removes oil and gas entirely – solid, fluid-free designs that take leakage and fire risk out of the equation, while performing reliably at the most demanding grid voltages, up to 765 kV.
- No SF₆
- GWP = 0 insulation
- Up to 420 kV
- −50°C
Our Clean Air line replaces SF₆ – a greenhouse gas with a global warming potential 24,300× that of CO₂ – with clean air, delivering full insulation performance with a global warming potential of zero.
