Mission Critical Group Announces Strategic Investment in WattEV to Advance 800 VDC Power Infrastructure for AI Factories
MCKINNEY, Texas, April 14, 2026 – Mission Critical Group (“MCG”), an end-to-end power systems and solutions provider specializing in design, manufacturing, delivery, and services, today announced a strategic investment in WattEV. MCG will leverage WattEV’s field-proven power-conversion technology to redefine power delivery for AI factories through next-generation 800 VDC architecture.
MCG will lead the industrialization and deployment of a medium-voltage Solid-State Transformer (SST) platform. The SST technology is a critical component in the transition to the 800 VDC architecture. MCG will deliver fully engineered, high-capacity power systems built on this technology.
As AI workloads rapidly scale, traditional power architectures are reaching their limits, driving the need for more efficient, high-density power delivery.
“We are building the next evolution in modular power delivery,” said Jeff Drees, CEO of Mission Critical Group. “The investment in WattEV highlights our commitment to advancing solutions for ultra-high-density AI workloads, including generative AI and inference.”
This new modular design enables flexible configuration, faster installation, easier expansion, and less complexity, supporting efficient deployment in large-scale environments.
“We are moving beyond incremental improvements to a fundamentally different power architecture,” said Michael Maiello, SVP of Innovation at Mission Critical Group. “By converting the ultra-high-power demands of AI directly from medium-voltage AC to 800 VDC, we unlock the full efficiency and performance benefits of 800 VDC distribution.
“Our technology is already proven in high-power, real-world applications where efficiency and reliability are critical,” added Salim Youssefzadeh, CEO of WattEV. “Together with MCG, we’re bringing that performance into the data center to accelerate the adoption of 800 VDC architectures with confidence and speed.”
