The system integrates lithium iron phosphate (LFP) battery enclosures, power conversion systems, controls, thermal management and safety systems into a factory-assembled unit intended to reduce on-site engineering and commissioning work.
Prevalon said the HD5 AC platform delivers 5MWh per enclosure and is designed for utility, independent power producer, hyperscale data centre and renewable integration applications. The company claims the architecture eliminates the need for a 1500V DC collection system, reducing trenching, cabling and associated EPC costs.
Tom Cornell, president and chief executive officer of Prevalon Energy, said: “The HD5 AC is about delivering real project value from day one. By moving complexity out of the field and into the factory, we’re helping customers lower installation costs, accelerate timelines, and reduce execution risk across the entire project.”
According to the company, the platform supports 2-, 4- and 8-hour storage configurations and can achieve up to 92.5% round-trip efficiency in four-hour operation. Prevalon also said the system is rated for more than 8,000 cycles to 65% state of health and a 20-year operating life.
The company emphasised safety and commissioning flexibility as key design priorities. The HD5 AC incorporates liquid cooling, integrated explosion detection and ventilation systems compliant with NFPA 69 standards, and self-powered auxiliary systems that allow commissioning before grid connection is available.
Alejandro Schnakofsky, chief technology officer at Prevalon Energy, said: “Every design decision in the HD5 AC is focused on improving how the system performs in the field.
“From fault isolation to serviceability, we’ve built a system that gives operators more control, reduces operational risk, and helps maintain performance over the full life of the asset.”
Prevalon’s wider HD5 storage platform
The launch builds on Prevalon’s wider HD5 storage platform, which includes systems for microgrids and data centres, alongside the company’s insightOS energy management system. Earlier this year, Prevalon announced deployments of its Hybrid Power Stabilizer platform for AI-driven data centre applications and said it was already executing nearly 1.3GW of projects in that segment.
Prevalon, a joint venture between Mitsubishi Power Americas and EES, says it has deployed more than 6GWh of utility-scale battery energy storage globally across more than 35 projects.
