Siemens expands data center partner ecosystem to scale next-generation AI infrastructure
Building an ecosystem for next-generation AI infrastructure
“Scaling AI infrastructure isn’t just a computing challenge, it is equally
an energy and infrastructure challenge,” said Ruth Gratzke, President of
Siemens Smart Infrastructure U.S. “As demand for AI processing accelerates,
data center growth is increasingly constrained by grid capacity and
interconnection timelines. Addressing this requires complex coordination across
both the digital and energy domains. Siemens is actively investing in key
technologies
and partnerships to expand the ecosystem required to scale AI
responsibly and support the next generation of data center infrastructure.”
Emerald AI enables AI workloads to shift in time and location to align
with grid conditions, allowing data center demand to respond dynamically to
available power. By coordinating when and where AI workloads run alongside
dispatching onsite energy resources, this approach helps smooth peak demand,
achieves faster and larger grid connections for data centers, and reduces
pressure on constrained power infrastructure. The strategic investment in
Emerald AI strengthens Siemens’ ability to introduce flexibility at the compute
layer. When combined with Siemens’ expertise in power infrastructure and
operational technology, this creates true IT/OT convergence between AI
workloads and power systems.
A key element of this expanded ecosystem is the addition of Fluence’s
grid-scale energy storage solutions, designed to support the next generation of
high-performance AI data centers. As compute clusters grow in size and density,
Fluence energy storage solutions enable data centers to accelerate grid
connection by shaping load and coordinating ramp rates, making large AI-scale
demand more predictable and easier for utilities to approve. This can turn
power-constrained locations into viable data center sites and accelerate time
to power, which can enable deployment of energy storage in months rather than
years of grid upgrades. Fluence’s energy storage solutions can also provide
dispatchable, on-site power that aims to enable data centers to operate during grid
build-outs, capacity shortfalls, or outages. By supporting consistent power
quality and flexible scaling, Fluence can help data center operators bring
capacity online faster while maintaining the reliability required for
mission-critical AI workloads.
Strengthening this ecosystem further, Siemens is collaborating with
PhysicsX to apply physics AI to the design and operation of data center power
distribution systems. Using AI models trained on Siemens’ multi-physics
simulation data, engineers can predict thermal behavior in complex busway
systems in real time. With PhysicsX, simulations that once took days can run in
under a second, enabling faster design iteration, optimized infrastructure for
dynamic AI workloads, and the foundation for predictive monitoring across
entire facilities.
The rapid growth of AI will continue to place new and often highly
dynamic demands on power systems, with large training and inference clusters
creating rapidly shifting loads that challenge traditional grid planning and
data center design. As a result, operators must find new ways to manage these
demands while maintaining the performance and reliability required for AI
infrastructure. Siemens’ expanded ecosystem is designed to help address this
challenge by bringing together AI workload orchestration, grid-integrated
energy systems, and AI-optimized physical infrastructure to support the next
generation of AI infrastructure.
