Prime Batteries Technology has started work to expand its plant in Romania, increasing production capacity from 2.5 GWh to 8.5 GWh, company CEO Vicențiu Ciobanu announced. “Last week we obtained the building permit for another 6 GWh and we have already started site works,” he said at the conference “RES market towards maturity”, organized by Energynomics.
At the operational level, by the end of September, Prime will have 226 MWh of batteries installed in existing renewable systems, mainly in PV + battery configurations. By the end of the year, the company expects to deliver another 152 MWh in integrated renewable projects and 227.8 MWh in stand-alone systems. The remaining planned projects, about 25% of the total, will be completed in the first quarter of 2026, due to delays related to ATR updates and solution studies.
Thus, instead of the original target of 800 MWh by 2025, the company will actually deliver 605.8 MWh. “We are approaching 75% of the target, and the rest of the projects have only been postponed, not canceled,” Ciobanu stressed.
From a technological point of view, Prime has introduced into production a new battery management system platform for up to 2 kV, adapted to the requirements of the European market, and a neural network for optimizing battery functions (state of charge, state of health), with a direct impact on trading operations. In addition, the company uses single crystal active materials dedicated to stationary applications that significantly reduce internal resistance and increase round-trip efficiency.
A case study presented by Ciobanu shows that, for a 100 MWh stand-alone plant, the efficiency difference between classical technologies and Prime solutions can generate annual savings of around 500,000 de euro in wasted energy and around 1,400 euros in ancillary cooling and conditioning costs.
In parallel, Prime Batteries is strengthening its local and international partnerships. Together with Monsson, the company has expanded existing storage projects and supported the development of a battery components factory in Petrila, a project coordinated by its partners and designed to support the industrial value chain in Romania. “We have demonstrated that it is possible to make competitive industry here, with quality products delivered to international markets,” concluded the CEO.
The company is currently working with large renewable energy developers and energy suppliers that are hybridizing existing parks. “All companies that have invested in renewables are hybridizing their systems. It is essential to build a sustainable financial model,” emphasized Vicențiu Ciobanu.
