AUSTIN, Texas--(BUSINESS WIRE)--Aug 3, 2026--
Hyliion Holdings Corp. (NYSE American: HYLN), a developer of modular power generation technology, today announced the successful demonstration of multiple KARNO™ Power Modules operating together as a single coordinated generation system. During the test, the two 200 kW units automatically shared changing electrical loads while maintaining stable power delivery.

The demonstration validated the KARNO Management System’s ability to coordinate multiple Power Modules and dynamically adjust the contribution of each unit as power demand changes. This capability is designed to improve system flexibility, optimize module operation, and support reliable power delivery across applications with variable electrical loads. In addition, the test supports Hyliion’s development of a standardized 800 kW building block and larger 2.4 MW and 3.2 MW power plant configurations with multiple 200 kW KARNO systems operating in parallel seamlessly.
"This demonstration validates one of the most important elements of our commercialization strategy," said Thomas Healy, Founder and Chief Executive Officer of Hyliion. "KARNO Power Modules can now operate together as one larger power plant. It shows that customers can combine KARNO Power Modules to meet the needs of an individual site while using the same standardized technology as we expand to multi-megawatt systems.”
Hyliion’s proprietary controls architecture, KARNO Management System can coordinate large installations of KARNO Power Modules on a common network. Its distributed control architecture automatically assigns one module to coordinate the system and can transfer that responsibility to another module if the active controller becomes unavailable, improving resilience and reducing single points of failure in the system.
The capability is relevant across a broad range of applications. Two or three KARNO Power Modules could support the power requirements of a large commercial facility, while the multi-megawatt configurations could serve data centers, industrial facilities, and defense installations.
