What Prime Batteries Technology does
Prime Batteries Technology is a Romanian privately held company founded in 2016 that designs and manufactures lithium-ion battery cells, packs, and fully integrated Battery Energy Storage Systems (BESS) from a single Gigafactory in Otopeni, Romania. The company describes itself as the largest cell-to-system BESS manufacturer in the European Union, executing every production stage — electrode manufacturing, cell production, pack integration, system assembly, and commissioning — under one roof with one team. Its product portfolio spans four containerized BESS form factors (5 FT, 10 FT, 20 FT offering 2–4.5 MWh, and 40 FT offering 6–9 MWh), two automotive battery packs (EV 10.5 and EV 79), and three proprietary technology platforms: a Battery Management System with 2 mV per-cell voltage accuracy and 100 ms telemetry, a cloud-based Energy Management System with predictive maintenance and sub-50 ms frequency-regulation response, and Power Conversion Systems delivering up to 98% round-trip efficiency across 20–3,658 kW outputs and 150–1500 V DC ranges.
The company's business model is anchored on direct enterprise hardware sales of BESS and automotive batteries, supplemented by recurring revenue from turnkey project delivery, commissioning, cloud-connected monitoring, predictive maintenance, and remote-control services over the operational life of each deployed system. Pricing is project-based and not publicly disclosed. Prime Batteries serves three primary customer segments — utility-scale energy storage (grid operators, IPPs, state-owned utilities such as Hidroelectrica), industrial and commercial buyers (manufacturing sites, commercial buildings, EV-charging integrators), and European automotive OEMs — and reaches them through a direct enterprise field-sales motion, project developer partnerships (Monsson Group, Simtel, Enevo Group), and event-driven demand generation at major European trade shows.
The company is privately held and backed by EIT InnoEnergy, which committed over €1 billion in November 2022 to scale the Gigafactory from 2 GWh to 8 GWh by 2026. It has since received additional capital from T2Y Capital and formed a joint venture in South Korea for active material production. Operating geographies include Romania and South Korea, with claimed end-customer reach across multiple countries worldwide. Revenue and profit increased in 2024, and in early 2026 Prime Batteries was ranked among the world's top energy storage equipment makers by BloombergNEF.
