Key Players
Competitive Landscape
Factory acceptance contracts for AI racks are awarded on test bay capacity, witness access and price, since an owner needs measured power and coolant results before shipment. Vertiv is expanding physical test capacity at the Tognana campus in Italy, and Schneider Electric and Siemens are publishing reference designs that define test interfaces for NVIDIA rack systems. Jacobs is approaching the same work from the owner side through virtual commissioning. Deal activity through 2036 is expected to center on test laboratories, CDU testing skills and regional witness teams close to large AI campuses.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| Schneider Electric | September 2025: AI reference designs with integrated power and liquid cooling controls | Owners want validated designs for GB300 NVL72 racks at up to 142 kW. | Reference designs are carrying digital twin models into deployment. | Test providers can build factory scripts around published reference designs. |
| Jacobs | March 2026: digital twin solution for AI data centers on Omniverse DSX | Owners want greater certainty before committing capital to gigawatt-scale sites. | Virtual commissioning is moving checks ahead of physical test slots. | Managed packages can link design models to factory and site acceptance. |
| Vertiv | July 2026: Tognana campus expansion with a large-scale testing laboratory | Buyers want thermal performance validated under expected site conditions. | Suppliers are adding physical test capacity for high-density cooling. | Witnessed chiller and liquid cooling tests can become a paid service line. |

Who Leads the AI Rack Factory Acceptance Testing Services Market?
Leadership in the AI rack factory acceptance testing services market is shared across three supplier groups. Vertiv and Schneider Electric lead in integrated infrastructure and factory test services, Siemens leads in electrical distribution and controls commissioning, and Jacobs covers EPCM and virtual commissioning.
Which Companies Provide Integrated AI Infrastructure and Factory Test Services?
Vertiv and Schneider Electric form the integrated infrastructure group. Vertiv offers customer witness testing at the Tognana campus in Italy, and Schneider Electric released NVIDIA-aligned reference designs with integrated power and liquid cooling controls in September 2025.
Which Companies Lead Electrical Distribution and Controls Commissioning?
Siemens leads this group with electrical distribution, automation and Level I-V data center commissioning. The company announced a joint liquid cooling and power reference architecture with nVent in December 2025 for 100 MW hyperscale AI data centers.
Which Companies Provide EPCM and Virtual Commissioning?
Jacobs provides engineering, procurement and construction management with off-site modularization for AI facilities. The company released a digital twin solution in March 2026 that supports virtual commissioning of compute, power, cooling and water systems.
Representative Company Overview
| Company | Positioning | Verified Development |
|---|---|---|
| Vertiv | Critical power and cooling company with manufacturing, integrated testing and customer witness facilities for data center cooling systems. | In July 2026, Vertiv announced a Tognana campus expansion with a large-scale testing laboratory in Italy. |
| Schneider Electric | Energy management company supplying AI factory reference designs with integrated power and liquid cooling controls. | In September 2025, Schneider Electric announced reference designs for NVIDIA GB300 NVL72 systems at up to 142 kW per rack. |
| Jacobs | Engineering and project delivery company offering modularization, system validation and virtual commissioning for AI facilities. | In March 2026, Jacobs released a digital twin solution for AI data centers built on the NVIDIA Omniverse DSX blueprint. |
Company Selection and Benchmark Notes
Companies enter the benchmark when documented evidence links the company to factory or witness testing, combined power and cooling validation or digital commissioning for AI racks and halls. The profiled set is structured in three groups, covering integrated AI infrastructure and factory test services, electrical distribution and controls commissioning, and EPCM and virtual commissioning. Siemens is scored on Siemens capabilities alone, with nVent liquid cooling treated as a partner input, so no business line is counted twice. Ratings compare observable capabilities, and a Low score marks limited public documentation or an adjacent role.
