T2Y Capital Invests in Romania’s Energy Storage Leader, Prime Batteries

• T2Y Capital becomes the second-largest shareholder in Prime Batteries Energy Holding S.r.l.
• Strategic partnership accelerates European expansion of Prime Batteries’ high-growth battery business
• Investment fuels scale-up to 8 GWh production capacity by 2030 and global sales expansion
• T2Y Capital continues to back European champions of the energy transition

T2Y Capital, a growth equity fund focused on energy and sustainability, has entered a strategic partnership with Romanian energy storage innovator Prime Batteries Energy Holding S.r.l., acquiring a significant stake to become its second-largest shareholder. The investment, subject to regulatory approvals, is set to propel Prime Batteries’ international expansion and scale its production footprint across Europe.

Headquartered in Bucharest, Prime Batteries is among the EU’s leading manufacturers of lithium-ion-based energy storage systems. The company delivers fully integrated solutions—ranging from battery cells to in-house battery management software—used to stabilise renewable energy flows, power speciality vehicles, and support industrial electrification. Its vertically integrated structure and independent supply chain give Prime Batteries a competitive cost and innovation edge.

As part of the deal, T2Y Capital will take a seat on the Board of Directors and play an active role in supporting Prime Batteries’ next growth chapter. The partnership aims to expand production capacity from today’s 2 GWh to over 8 GWh by 2030, while aggressively pushing international sales and the company’s innovative Battery-as-a-Service model.

Prime Batteries is a European hidden champion. It combines deep technological know-how with a profitable business model and international potential. We look forward to helping them scale up operations and drive the European energy transition. Europe must reduce energy dependence and advance industrial decarbonization. That means backing local innovators with global potential. Prime Batteries is exactly the kind of company that can lead Europe’s energy future.

Founded in 2016, Prime Batteries has already demonstrated strong growth and strategic independence in all key technological areas—cells, software, raw materials, and system integration. It currently operates a 300 MWh production facility and is ramping up a new 2 GWh plant to meet rising demand for energy storage in mobility, industry, and grid stabilisation.

T2Y Capital brings more than capital—it’s the right strategic partner to help us accelerate, scale up, and take our solutions to new markets.
