February 2, 2026, San Diego, CA – IONATE and JST announce their collaboration to bring the Hybrid Intelligent Transformer (HIT) to the U.S. market. This technology is designed to give industrials, data centers, and grid operators greater control over increasingly volatile power flows.
The Pressure on U.S. Power Systems
U.S. data-center electricity demand is expected to more than double by 2030, reaching up to 9% of total national electricity use. At the same time, grid reliability is at risk, as sensitive load growth outpaces upgrades to an aging network.
Power-quality issues such as voltage instability and harmonics are becoming more frequent, costing the U.S. economybetween $150–250billion annually through lost production, equipmentdamage, and unplanned downtime, according to research by the Electric PowerResearch Institute (EPRI).
As AI adoption and electrification accelerate, failure to upgrade core power infrastructure further threatens reliability, productivity, and economic performance – particularly in industries that depend on high-quality, uninterrupted power, like large-scale manufacturing and data centers.
A New Building Block
IONATE’s Hybrid Intelligent Transformer combines the robustness of conventional transformers with the dynamism of solid-state systems, delivering an all-in-one upgrade at the substation level. A Swiss-army knife for power management, the HIT unlocks capabilities that have historically required multiple standalone devices.
Beyond stepping voltage up or down, HITs provide:
- Monitoring & visibility: Real-time, kilohertz-level data on power conditions
- System stability: Stepless voltage regulation, and phase balancing
- Power quality & efficiency: Simultaneous mitigation of voltage and current harmonics, four-quadrant reactive power control
These capabilities allow operators to protect sensitive loads, prevent power-quality-driven failures, increase energy efficiency, and strengthen operational resilience – all within the footprint and fail-safe architecture of a standard transformer. No substation redesign required.
Industrial-Scale Manufacturing Meets AI-Powered Grid Tech
The partnership brings together JST’s trusted, large-scale transformer manufacturing expertise with IONATE’s proprietary hybrid power-electronics and AI-enabled control technology. As part of the collaboration, JST will manufacture and bring to market transformers integrating IONATE’s technology.
The collaboration marks the commercialization of IONATE’s HIT technology, moving from early deployments with utilities and power users to full commercial availability. Pilot units are already under live evaluation with leading industrial and energy partners, and volume production will begin at JST’s North American facilities, including Wytheville, VA.
The first 3 MVA, 34.5kV- and 13.2kV-ratedHybrid Intelligent Transformers will be available to US customers in the second half of 2026.
Executive Perspective
JeanneLi, Director of Business Development at JST, said:
“JST is pleased to partner with IONATE in bringing an important new capability to the US market. As power systems evolve and infrastructure demands grow, customers are seeking solutions that improve reliability without forcing a complete overhaul of their existing assets. The Hybrid Intelligent Transformer provides a practical, immediately deployable option that fits directly into today’s transformer footprints, allowing operators to strengthen power quality and system resilience while transitioning at their own pace. By combining JST’s manufacturing expertise with IONATE’s innovative technology, we’re supporting grid operators, data centers, and other power‑sensitive users as they modernize responsibly and address emerging power‑quality challenges.”
Matthew Williams, CEO of IONATE, said:
“JST is a trusted manufacturer with deep transformer expertise, gigawatts of manufacturing capacity, and the ability to deliver at pace. That combination makes them an ideal partner as we bring HITs to the US market.
We’re seeing unprecedented pull from industrial players and data-centre operators who need more than passive power infrastructure; they need smart operations optimized forefficiency and robustness. Together, we’re not just introducing a new product –we’re setting a new standard for how power systems are built and operated.”
