Siemens and Delta: Building Greener Data Centres Faster

Data centre operators continue to face unprecedented pressure to build capacity at speed as AI and cloud demand accelerate. 

In response, Siemens Smart Infrastructure and Delta Electronics (Delta) have formed a global partnership to develop prefabricated, modular power systems designed to shorten deployment timelines and reduce cost and carbon for hyperscale and colocation sites.

Modular power moves into the mainstream

Prefabricated electrical infrastructure has become a growing focus for operators seeking to standardise construction and avoid delays linked to supply chains and skilled labour. 

The Siemens and Delta collaboration brings these ideas together in a joint platform centred on containerised, pre-tested power blocks that can be deployed as plug-and-play units.

The companies say the approach can reduce time-to-market by as much as 50% while lowering construction risk, improving predictability and freeing up white space by moving power equipment into compact external enclosures.

“Delta's commitment to energy efficiency is foundational to this agreement,” says Jimmy Yiin, Executive Vice President of Global Business Operations at Delta Electronics, Inc. “By leveraging our expertise in power solutions from grid to chip, which enables us to architect the system closer to the critical load, our Uninterruptible Power Supply (UPS), batteries, and advanced thermal management technologies are uniquely designed for the high-density demands of the AI era. 

“Working with Siemens allows us to further expand the reach of our cutting-edge, energy-saving solutions rapidly through a single, globally supported supply chain across EMEA and APAC.”

Standardised power blocks for high-density sites

The partnership centres on prefabricated containerised power solutions, including skids and eHouses. 

These units integrate UPS systems, switchgear, battery technologies and cooling components within an optimised footprint. Because fabrication and testing take place off site, the modules arrive ready to integrate with facility power distribution, reducing the number of trades required on location and mitigating weather or supply chain delays.

According to the companies, the optimised layouts can reduce CapEx by up to 20%. A smaller construction footprint can also reduce carbon emissions by up to 27%, largely due to lower concrete use and streamlined installation.

“Our partnership with Delta represents an important milestone for data centre construction in the world's fastest-growing markets,” says Stephan May, CEO of Electrification & Automation at Siemens Smart Infrastructure. “By combining Siemens' electrical power distribution and engineering services with Delta's high-efficiency UPS, battery and cooling offerings, together we are delivering a prefabricated, customisable solution that can drastically cut time-to-market by up to half. 

“This approach also lowers construction risk with better predictability, while enhancing energy efficiency and supporting the long-term sustainability goals of our customers.”

Digital twins and lifecycle efficiency

Another element of the partnership is the use of Building Information Modelling (BIM) across the design and integration process. 

By creating a digital twin of the power systems, Siemens and Delta aim to provide operators with a detailed virtual model that supports engineering coordination, installation planning and ongoing operations.

The BIM model enables real-time data integration into building management systems, allowing teams to monitor performance, identify issues earlier and streamline maintenance. 

For operators managing large fleets of facilities, digital twins also offer a route to standardise deployments and compare system performance across regions.

Partnership structure

Siemens frames the collaboration as part of a wider effort to work with complementary technology partners across the data centre value chain. 

By combining Delta’s power and thermal technologies with Siemens’ electrical distribution and engineering capabilities, the companies aim to provide a coordinated route for deploying modular power infrastructure in new sites.

The partnership agreement focuses on delivering these prefabricated systems across EMEA and APAC, with both companies supporting customers through their global service networks.
