BEYOND BATTERIES
Every battery pack we manufacture is controlled by our proprietary BMS, developed in-house, matched to our own cells, and engineered to manage performance across the full system lifetime.
Active materials are assembled piece by piece on highly-automated production lines, with process control at the cell level.
We count time in megawatt-hours. 2,300 MWh of annual production capacity, running 365 days a year. Output has grown 10x in the past three years, driven by our own manufacturing chain, on our own terms.
Our supply chain is European by design. The same discipline that runs our production floor carries through to every project we deliver, across 70+ countries.

BUILT ON MORE THAN BATTERIES
Making a battery system that performs over time starts with decisions made long before it leaves the factory. Who manufactures the cells. How the production chain is controlled. Whether the solution is matched to the application. And the commitment to stay involved when it matters most. These are the four pillars Prime is built on.
In-House Engineering
Every Prime system is built within one production chain, from electrode to final pack assembly. That's what keeps quality consistent, regardless of project scale.
Flexible Solutions
One battery does not fit all. Prime delivers adaptive chemistry, modular sizing, and proven manufacturing across a range of business models and applications. Each solution is engineered to the requirements of its end use.
Vertical Integration
Prime manufactures its own Li-ion cells from scratch. Every stage of production happens within a single facility, ensuring consistent quality, full traceability, and a system built to perform exactly as engineered.
Long-Term Partnership
A battery system operates long after commissioning day. Prime stays involved, through monitoring, maintenance, and performance optimization, because the real measure of the work is how it runs over time.
The Long View
How we build matters just as much as what we build. The same principles that go into every system apply to every stage of the production process.
