Nvidia has launched its DSX Ready qualification program for AI data center infrastructure, naming just three qualified battery energy storage system (BESS) suppliers: Tesla, LG Energy Solution, and Hitachi Energy. The program introduces BESS and liquid cooling qualification for Nvidia’s AI factory reference designs, establishing a new set of standards for vendors seeking to supply these critical components to hyperscale and colocation operators.

DSX Ready sets new supplier standards
Nvidia’s DSX Ready initiative marks a strategic expansion beyond its core AI computing lineup into the physical backbone of AI data centers: power and cooling. This vendor qualification framework requires battery energy storage system suppliers to meet stringent functional and safety standards that align with Nvidia’s AI factory reference architectures, while unifying supply chain practices for data center builders.
For BESS, Nvidia has codified requirements primarily focused on the behavior of the power conversion system at the AC interface. These specifications address active and reactive power response, current limiting, ride-through performance, grid-forming capability (islanded operation), and the ability to execute black starts. The DSX Ready process also mandates explicit documentation of industry certifications for fire safety, grid connection, and cybersecurity, reflecting the increased regulatory scrutiny on large-scale data center energy infrastructure.
Manufacturers vying for DSX Ready status must produce detailed evidence packages, including raw time-series data, performance plots, and configuration disclosures tied directly to Nvidia’s technical requirements. Nvidia then reviews the vendor’s submission, but the qualification does not extend to or replace site-specific engineering, such as transformer or generator integration. This boundary underlines that while reference standards are advancing, they are not a one-size-fits-all approach for project execution.
Who made the cut: Tesla, LG, Hitachi
At program launch, only three manufacturers have been named as certified DSX Ready BESS suppliers: Hitachi Energy, LG Energy Solution, and Tesla. Each company’s systems have demonstrated compliance with Nvidia’s current requirements, establishing a shortlist of vendors for hyperscale and enterprise buyers constructing or upgrading AI data centers to DSX specifications.
The narrow set of qualified providers is notable given the expanding volume of battery installations required by new data center builds, especially in the U.S., where grid capacity and reliability concerns are pushing operators toward on-site and behind-the-meter storage. By limiting the opening cohort to three major global players, Nvidia is signaling a preference for proven and deeply-resourced manufacturers, likely favoring systems with robust performance validation and mature supply chains.
This initial selection also sets a visible benchmark for other battery manufacturers aspiring to enter Nvidia’s preferred procurement funnels, raising questions about future qualification cycles and the potential for additional categories or more granular technical requirements as the program matures.
Qualification mechanics and limitations
The DSX Ready process for BESS begins with the supplier. Vendors are responsible for completing internal validation tests and assembling a comprehensive dossier of technical evidence. Nvidia, acting as the program gatekeeper, evaluates these inputs against their published requirements but explicitly disclaims any guarantee of project-level reliability or site-specific grid stability.
Unlike some hardware reference programs that endorse an end-to-end solution, Nvidia defines the qualification boundary at the device and interface level. Key infrastructure elements such as transformers, switchgear, and backup generators are recognized as outside the program’s purview. This ensures that end users and developers remain responsible for detailed system integration and on-site reliability assessments in collaboration with their engineering and EPC partners.
The vendor qualification demands transparency in adherence to existing standards, which encompass U.S. and international guidelines for grid interconnection, fire and thermal safety, and digital controls, reflecting both operational and due diligence expectations from institutional buyers.
Implications for data center buyers and supply chains
Nvidia’s DSX Ready badge is poised to function as a buying signal for hyperscalers and developers facing schedule, permitting, and reliability challenges. By concentrating early qualification among three suppliers, Nvidia provides a level of vendor risk reduction that could accelerate procurement and financing for DSX-compliant builds, especially where investor or customer requirements tilt toward validated ecosystem partners.
The immediate effect may be most pronounced in the United States, where obstacles to grid expansion and reliability on-ramps are driving data center campuses to adopt ever-larger BESS installations. With Nvidia’s reference designs increasingly influential in site planning and RFP issuance, the DSX Ready list is likely to shape shortlists for new projects, especially for projects aiming to demonstrate resilient, grid-aware dispatch at industrial scale.
However, the program’s strict initial cohort may also heighten competition for qualified systems and lead to near-term supply bottlenecks, depending on regional build schedules and project backlogs. Developers will need to closely track future DSX program updates to see if additional suppliers or new equipment categories are brought under the Nvidia umbrella in the coming months.
What this means for buyers
Data center equipment buyers in the United States have a new reference standard for BESS procurement. Only Tesla, LG Energy Solution, and Hitachi Energy are DSX Ready qualified as of the September 2026 program launch, which will shift supplier due diligence and project timelines for AI data center developments using Nvidia reference designs. Buyers planning 2026 to 2027 buildouts will need to align equipment selection with this stringent shortlist to satisfy Nvidia’s DSX-based requirements.
