The global energy system is in transition - balancing decarbonisation with security, and innovation with reliability. Transition on this scale brings challenges: securing resilient supply chains, maintaining quality under pressure, and balancing the speed of transformation with the need for long-term sustainability.
From the bolts holding turbine towers together to the fasteners anchoring nuclear reactors and generator housings, CTB Group’s engineered solutions play a quiet but critical role in keeping global infrastructure safe and efficient.
This article marks the first in our new CTB Blog Series: Supporting the Energy Infrastructure of Tomorrow - exploring the challenges and opportunities shaping today’s energy market. Over the coming months, we’ll look at how CTB Group is helping to power progress across nuclear, oil & gas, wind, static power for AI data centres, and more.
Together, these stories show how a century of engineering expertise and a global footprint position CTB Group at the forefront of the energy transition: connecting the world’s most critical industries with confidence.
Engineering Confidence in Every Connection
In sectors where reliability is non-negotiable, CTB Group delivers complete end-to-end capability: from R&D and forging through to machining, coating, testing, and global distribution. Every product is designed and manufactured under strict international standards, including ISO 9001, ISO 14001, ISO 45001, and DIBt certification.
This vertical integration enables CTB to serve high-risk, high-demand projects with the precision and agility global infrastructure now requires. Whether manufacturing large-diameter wind fasteners, subsea assemblies, or components for nuclear installations, CTB’s systems, people, and certifications are engineered for confidence every step of the way.
Powering the Transition: Energy in All Its Forms
Wind: Building the Renewable Backbone
The global wind turbine market was valued at US $174.5 billion in 2024 and is expected to grow more than 11% through 2034, with record annual installations of 117 GW in 2023 - a 50% increase year-on-year. This momentum underscores wind’s role as the backbone of the renewable transition.
CTB’s DIBt-certified, large-diameter fasteners are designed to withstand extreme load, vibration, and weather conditions. As turbine components increase in scale, the structural reliability of every connection becomes even more critical. CTB’s precision engineering and testing capability help ensure those turbines turn safely for decades.
Nuclear: Unlocking Modular Potential
Next-generation nuclear, from SMRs to AMRs, is redefining how nations secure clean baseload energy. With UK–US partnerships fast-tracking modular reactor programmes, CTB’s experience in nuclear-grade, safety-critical fasteners provides a proven foundation for this new phase of low-carbon power.
Oil & Gas: Managing Today’s Realities
While the energy transition accelerates, oil & gas continues to underpin global supply and industrial stability. CTB supports operators maintaining and upgrading existing assets with corrosion-resistant, high-integrity fasteners - helping extend infrastructure life and reduce environmental impact.
Static Power: Securing AI’s Energy Backbone
The global surge in artificial intelligence and cloud computing has triggered a parallel boom in data-centre construction. These facilities run 24/7 and rely on static diesel or hybrid generators to guarantee uninterrupted power. Diesel models currently account for over 70% of the market.
For CTB, this presents a major opportunity. Its fasteners already support power-generation and heavy-engineering applications where reliability is paramount. From generator housings and base frames to vibration-resistant mountings, CTB provides the precision connections that keep data-driven infrastructure running safely and sustainably.
Global Reach, Local Strength
With operations across Europe, the USA, India, and China, CTB offers both local responsiveness and global consistency. This distributed network reduces logistics risk, shortens lead times, and ensures the same standards of quality, certification, and ESG performance wherever customers operate.
Regional presence also aligns with market growth. The Asia-Pacific region now accounts for more than 50 % of global wind capacity. By investing close to key customers - including renewable-energy OEMs and industrial technology leaders - CTB strengthens resilience across the global energy supply chain.
ESG, Certification, and Trust as Differentiators
Technical excellence alone isn’t enough. CTB’s leadership in sustainability and governance sets it apart as a partner to the world’s most scrutinised industries.
As one of the first in its sector to achieve full CBAM compliance across all EU declarant sites, CTB provides verified, product-level carbon data - ensuring customers remain compliant as global carbon-pricing regimes evolve. Every major site maintains ISO 14001 certification for environmental management and ISO 45001 for occupational health & safety, reinforcing CTB’s commitment to responsible operations.
Participation in the UN Global Compact further embeds transparency, ethics, and continuous improvement across CTB’s governance model - values that translate directly into customer confidence and long-term partnership.
Looking Ahead: Connecting Progress Across Sectors
Decarbonisation depends on the ability to build faster, safer, and smarter — without compromising quality or reliability. The wind industry must triple annual installations to around 320 GW by 2030 to meet global targets, while the backup-power market will continue to expand alongside AI and digital infrastructure growth.
CTB Group is ready to meet that challenge. With more than a century of manufacturing expertise, a global network of certified facilities, and a clear ESG vision, CTB continues to support the industries that keep the world moving.
