The exponential growth of AI is placing new and unprecedented demands on power infrastructure.
Data centres already account for around 1-2% of global electricity consumption, according to the International Energy Agency (IEA), and this is expected to increase significantly over the coming decade as AI workloads scale. Industry forecasts suggest demand from data centres could double by 2030, driven by the computational intensity of AI models and real-time processing requirements.
They are also being pushed to deliver higher uptime, greater resilience and consistent performance under increasingly large and variable loads. In this environment, power provision has become a defining factor in system design and operational risk.
Backup Power Becomes Core Infrastructure
Data centres are being built and upgraded to handle higher energy density, tighter uptime requirements and growing sensitivity to disruption. At the same time, grid infrastructure in many regions is struggling to keep pace with demand, creating a greater reliance on on-site power systems to ensure continuity.
Static diesel generators - increasingly paired with hybrid configurations - are central to this shift. These systems are no longer reserved for rare outages. They are expected to operate more frequently, respond instantly and maintain stable output under sustained load.
Industry forecasts reflect this change, with global backup power capacity for data centres projected to increase significantly over the coming years, driven in part by AI-related demand growth. For operators, this introduces a new set of challenges, and the margin for failure is minimal.
Within this context, static diesel and hybrid backup systems also play a transitional role. While long-term decarbonisation remains the objective, these systems help bridge the gap between current grid limitations and future energy infrastructure. In this way, they form part of the broader energy transition, supporting reliability while enabling the integration of more sustainable power sources over time.
Continuous Load, Continuous Stress: The Mechanical Reality
As backup systems take on a more active role, the physical demands placed on them increase.
Static diesel generators operating under sustained or repeated load are subject to constant vibration, thermal variation and cyclic stress. Over time, these forces act across the entire assembly - from generator housings and base frames to the interfaces with supporting structures and foundations.
Maintaining alignment, structural stability and load distribution under these conditions is critical. Small deviations can lead to fatigue, component wear or reduced system performance, and in high-demand environments such as data centres, these risks translate directly into operational exposure.
This is where mechanical integrity becomes a defining factor in system reliability. Components must not only meet specification at installation but continue to perform consistently over time, under real operating conditions.
Fastening plays a central role in this. High-integrity fasteners are responsible for securing key structural elements, maintaining clamping force and resisting loosening under vibration and load, so their performance underpins the stability of the entire system.
Fastening as a Design Requirement
Fasteners are rarely the focus of system design discussions, but their performance defines how assemblies behave over time.
In generator systems, bolted joints must maintain preload under conditions that promote loosening: vibration, load cycling and thermal expansion. These effects act continuously across structural interfaces, particularly in base frames and mounted components.
Loss of preload changes how load is distributed through the joint. This can introduce micro-movement, increase stress concentration and accelerate fatigue in both the fastener and the connected parts. In demanding operating environments, these effects accumulate quickly.
This is why fastening must be treated as a controlled engineering variable. Material selection, thread engagement, surface condition and tightening method all influence whether a joint performs as intended throughout its life.
In applications where systems are expected to run predictably over extended periods, fastening design directly affects stability, maintenance intervals and long-term performance. Meeting these requirements consistently depends on experience in comparable operating environments.
Proven Capability in Power and Heavy Engineering
Cooper Turner Beck has an established track record in supplying high-strength fasteners for power generation and heavy engineering applications, where joint integrity under load is a defined performance requirement. This includes both static and rotating systems, where vibration, load distribution and long-term stability must be accounted for at the design stage.
Working with OEMs and EPC contractors across energy infrastructure projects, CTB supports applications where fastening performance is directly linked to safety, compliance, and system reliability. This experience informs material selection, manufacturing approach and quality assurance processes - ensuring that fasteners perform as intended once deployed.
With capabilities spanning forging, machining, testing and supply, CTB provides fastening solutions that are aligned to the operational demands of power systems. This includes components used across generator assemblies, structural interfaces and foundation connections.
Compliance, Traceability and Supply Chain Confidence
As data centre infrastructure expands globally, consistency in supply becomes as important as performance in application.
OEMs and EPC contractors require fastening solutions that meet the same standards across multiple sites, often under tight delivery timelines and within complex regulatory environments. This places greater emphasis on traceability, certification and supply chain resilience.
CTB supports these requirements through a global manufacturing and distribution network designed to deliver consistent product quality at scale. Compliance with international standards, including ISO and DIBt certification, provides assurance that components meet the necessary safety and performance criteria for use in critical infrastructure.
In parallel, increasing regulatory focus on carbon and supply chain transparency is shaping procurement decisions. CBAM-aligned processes and ESG commitments are now a core part of supplier evaluation, particularly for projects operating across European and international markets.
By combining certified manufacturing, controlled processes and global supply capability, CTB enables customers to specify fastening solutions with confidence in not just performance, but also compliance, availability and long-term traceability.
Increasing Scrutiny on Data Centre Infrastructure
As data centre capacity expands, expectations are extending beyond system performance to the components and supply chains that support it.
Operators and project stakeholders are placing greater emphasis on how infrastructure is sourced, manufactured and delivered. Alongside operational efficiency, there is a growing requirement for transparency in materials, processes and environmental impact.
This is shaping how projects are specified and evaluated. Procurement teams are expected to demonstrate clear visibility into supply chains, supported by documentation that aligns with carbon reporting frameworks and regional regulations.
For component suppliers, traceable materials, consistent manufacturing standards and alignment with evolving regulatory requirements are part of the baseline for participation in large-scale infrastructure projects.
CTB’s approach is built around these principles. ESG considerations are embedded within manufacturing processes, material sourcing, and supply chain management, ensuring transparency and consistency as standard. This enables customers to integrate compliant, traceable components into their projects from the outset.
Built for Systems That Cannot Fail
The performance of a power system is often associated with its major components: generators, controls and distribution. In practice, it is determined just as much by how those systems are held together.
Across generator assemblies and supporting structures, joint integrity defines how load is transferred, how alignment is maintained and how systems behave over time. These considerations influence stability, maintenance requirements and the consistency of output under real operating conditions.
For data centre infrastructure, where uptime expectations are high and operating margins are tight, this shifts how reliability is understood. It is not only a function of system design, but of the components that enable that design to perform as intended.
CTB operates in this space - supplying fastening solutions for applications where joint performance is integral to system behaviour, and where consistency over time is a requirement built into the design.
