Who Signed What
Mitsubishi Heavy Industries and Ingeteam have signed a memorandum of understanding to work together on power infrastructure for data centers in the United States. MHI announced the agreement in Tokyo on 15 October. It is non-binding, the US is the first market, and neither side gave figures for value or timing.
The split is simple. MHI brings systems integration, its experience with large energy plants and industrial cooling, and a North American service network through Concentric. Ingeteam, which has more than 4,000 employees in 15 countries, brings rotating electrical machines and power electronics: power conversion systems, generators, battery storage, power quality and grid stability equipment, and EMS / SCADA control platforms.
Three things are named in the release. MHI will open the US data center market to Ingeteam's power conversion products and software. The two will study building selected Ingeteam technology into MHI's own energy infrastructure designs. And they will look at further work on medium-voltage distribution, energy management and other equipment for high-density computing, subject to technical and commercial review.
The Problem Is Power Quality, Not Only Megawatts
The interesting part is how the companies describe the problem. MHI's Shin Gomi, who heads its data center and energy management department, says the industry has moved from securing power to delivering power of high quality. AI training loads swing fast, and the release names harmonic distortion and voltage imbalance as the result, with effects on reliability and on equipment life. Longer waits for grid connections are the second driver.
That matches what engineers on generation sites are hearing. A large AI hall that steps its load up and down in seconds is a different customer from a conventional data center with a flat profile, and the North American reliability rules for these loads are being written right now (see our item on NERC's proposed standards). For on-site engines or turbines the question is whether the machines see those swings directly or whether converters and storage take them first. Every load step that the electronics absorb is one the prime movers, and their auxiliaries, do not have to follow.
An MoU with no deployment dates is a statement of direction rather than an order. Still, it shows where a group that builds turbines, engines and cooling plant thinks the margin in data center power will be: in the electrical layer between the generator and the rack.
