Hitachi Energy and Samsung Join Forces for Data Centers
Hitachi Energy and Samsung's partnership marks a pivotal shift in HVAC grid infrastructure for data centers. Discover the future of energy solutions!
Data center power demand has shifted from surprising to alarming. Hyperscale campuses now routinely require hundreds of megawatts at a single site. Grid operators across North America, Europe, and Asia-Pacific are fielding interconnection requests they weren't built to process. Somewhere in that gap between what the grid can deliver and what the data center market needs, a massive business opportunity is taking shape.
Hitachi Energy and Samsung Engineering & Construction Group (Samsung C&T) are moving to fill it.
The two companies signed a non-binding Memorandum of Understanding in April 2026, formalizing a collaboration around high-voltage alternating current (HVAC) grid infrastructure — the backbone technology that moves bulk power from generation sources to the substations and switchgear feeding large load centers like data centers. This isn't a speculative partnership. Both companies arrive with track records, specific capabilities, and a clear commercial thesis.
What the MoU Actually Says — and What It Doesn't
Strip away the press release language, and this agreement is fundamentally a go-to-market alignment. Hitachi Energy brings the technology stack: grid engineering expertise, advanced electrical systems design, and integrated digital solutions. Samsung C&T brings construction execution — the engineering, procurement, and construction (EPC) capability required to put steel in the ground on complex transmission projects.
Together, the agreement tasks both companies with identifying AC grid opportunities, building a shared opportunity pipeline, and developing a roadmap for pursuing them jointly.
What makes this pairing credible is that it isn't theoretical — the companies have already worked together in the UAE and Australia on complex cross-border transmission projects. That existing relationship means the collaboration model is tested. The MoU is essentially scaling something that already works.
That said, it's worth being clear-eyed about what a non-binding MoU is: a statement of intent, not a contract. The commercial weight comes when specific projects get awarded. The strategic signal, however, is real.
Why HVAC Grid Infrastructure Is the Bottleneck Nobody Talks About
Most coverage of the data center power crunch focuses on generation — will there be enough natural gas, solar, nuclear, or storage to meet demand? That's a real problem. But even if generation capacity were abundant, it wouldn't matter much without the transmission and distribution infrastructure to deliver it reliably.
HVAC grid infrastructure — transformers, switchgear, transmission lines, substations — is where the actual bottleneck lives for many large data center projects.
Lead times on large power transformers have stretched to 18 months or longer in some markets. Interconnection queues at regional transmission organizations like PJM and MISO contain thousands of gigawatts of pending requests that will take years to work through. A hyperscale operator can break ground on a data center building in months, but securing reliable, high-capacity grid connection can take the better part of a decade in constrained markets.
That's the context in which this Hitachi-Samsung collaboration matters. By combining Hitachi Energy's grid technology expertise with Samsung C&T's EPC execution capability, the partnership is positioning itself to compress that timeline — offering a more integrated solution to utility clients, grid operators, and potentially the hyperscale operators themselves who are increasingly stepping in to self-fund transmission upgrades.
Each Company's Stake in the Data Center Market
Neither Hitachi Energy nor Samsung C&T is new to this space. Understanding their respective trajectories makes the logic of the partnership clearer.
Hitachi Energy has been systematically building its position at the intersection of grid technology and AI-era infrastructure. The company recently inked a deal to supply power transmission and distribution equipment to OpenAI's data centers — a direct relationship with one of the most power-hungry AI companies on earth. It also partnered with Southwest Power Pool, a regional transmission operator, to develop an Nvidia-powered AI solution designed to reduce the time required for interconnection impact studies. That last point matters: interconnection study backlogs are a primary cause of project delays, and any technology that accelerates them has real economic value.
Samsung C&T's data center ambitions are similarly concrete. The company signed a partnership to construct a 40MW data center in Gyeonggi Province, South Korea, and is working on a deal with Korea Southeast Power to develop an integrated data center powered by a 900MW hydrogen plant. Samsung C&T isn't just a construction contractor — it's positioning itself as an integrated infrastructure developer with a specific interest in where power and compute intersect.
When two companies with overlapping strategic interests in the same end market agree to collaborate on the enabling infrastructure, the combined addressable opportunity is larger than either could access alone.
The Renewable Integration Angle
There's a second-order benefit to this collaboration that deserves attention: renewable integration.
Niklas Persson, CEO of Hitachi Energy's Grid Integration Business Unit, specifically called out grid modernization and "large-scale integration of renewables" as objectives of the partnership. That language is deliberate. Much of the data center industry's stated sustainability commitments depend on being able to procure clean power at scale — which in turn depends on whether the transmission infrastructure exists to deliver that power from where it's generated to where it's consumed.
Solar and wind resources are frequently located far from population centers and load clusters. Getting that power to a data center campus in a suburb of northern Virginia or outside Phoenix requires transmission capacity that, in many cases, doesn't exist yet. HVAC grid infrastructure development is the physical prerequisite for the energy transition in data center markets — not just a reliability play.
The companies' combined AC and DC capabilities — Lee Byung-soo, Samsung C&T's EVP, referenced "integrated solutions that span both direct and alternating current technologies" — position them to address a range of transmission configurations, from long-distance HVDC lines to the HVAC substation interconnections closer to the load.
What Comes Next
The immediate work product from this MoU will be a shared go-to-market roadmap and an opportunity pipeline. Practically, that means the two companies will be mapping markets where grid infrastructure investment is accelerating — the United States, Middle East, Southeast Asia, and Australia are the obvious targets given their existing footprint and the pace of data center construction in each region.
For infrastructure investors and developers watching this space, the strategic signal is worth noting: the companies with the ability to deliver integrated grid solutions — technology plus EPC execution — are going to have a structural advantage over those offering either alone. Grid operators and utilities under pressure to connect new loads quickly don't have the bandwidth to manage fragmented vendor relationships. Turnkey solutions command premium positions in the queue.
For data center operators specifically, this kind of partnership represents a supply chain development they should be watching. The constraint isn't land or capital or even generation anymore. The constraint is the grid connection itself, and the companies that can deliver reliable, high-capacity HVAC infrastructure faster than the queue will determine who builds next — and who waits.
The broader infrastructure buildout required to support the AI era is still in early innings. The companies positioning now — building the partnerships, the pipelines, and the execution models — are writing the playbook for the decade ahead.
