Summary of the Conference Call on 800V DC Data Centre Architecture Industry Overview - The discussion focused on the transition from traditional AC data centre architectures to 800V DC systems, highlighting significant disruptions in both "white space" and "grey space" within the data centre industry [1][4]. Key Insights 1. **Transition to 800V DC**: - The shift to 800V DC will change power conversion locations and control dynamics, with sidecar architectures emerging as a key component [4][22]. - Open, non-proprietary designs are gaining traction, which may enhance competitive differentiation among vendors [4][4]. 2. **Disruption in White and Grey Spaces**: - White space refers to areas where IT racks are located, while grey space involves adjacent technical rooms with heavy electrical and cooling systems [4][22]. - Different vendors are disrupting these spaces in unique ways, with no single vendor dominating both areas [4][24]. 3. **MV Solid-State Transformers (SST)**: - MV solid-state transformers are seen as a promising technology for data centres, offering higher efficiency and integration of multiple functions, although they are currently costly and immature [4][30]. - The technology is expected to take two years to mature due to safety standards and quality issues [4][31]. 4. **Impact of AI Workloads**: - The rise of AI workloads is accelerating power design decisions in data centres, necessitating earlier engagement from vendors [4][4]. 5. **Market Dynamics**: - A more concentrated customer base is changing go-to-market strategies for power, electrical, and infrastructure suppliers [4][4]. - Traditional boundaries between utility, MV, and data centre vendors are blurring, leading to potential new entrants in the market [4][4]. 6. **Market Share Projections**: - By 2030, 800V DC systems are expected to capture 23.9% of the North American market and 19.4% in Europe, with significant impacts on traditional power architectures [4][61][62]. - The market growth for traditional power infrastructure is projected to stall after 2028, indicating a shift in investment focus [4][61][62]. Potential Winners and Losers - **Winners**: - Companies like Eaton, ABB, and Delta Electronics are positioned to benefit from the transition due to their existing technologies and market strategies [4][36][71]. - **Losers**: - Traditional vendors in the white space may face significant risks as the transition to 800V DC could dilute margins and require substantial investments [4][75][78]. - Companies lacking experience in DC power supplies or those relying on a buy-and-resell model may struggle to compete effectively [4][74]. Risks and Considerations - The transition to 800V DC is expected to be margin-dilutive for traditional vendors in the initial years due to required investments and the immature state of MV SST technology [4][82]. - The market for low voltage products may be at risk as the industry shifts towards higher voltage systems [4][38]. Conclusion - The call highlighted the transformative potential of 800V DC systems in data centres, emphasizing the need for traditional vendors to adapt to changing market dynamics and technological advancements to maintain competitive advantages [4][4][82].
