August 1, 2025: Equity investor T2Y Capital said on July 29 it will become the second-largest shareholder of Romanian lithium ESS company Prime Batteries Energy Holding.

Newly founded T2Y said it would support Bucharest-headquartered Prime’s international scale-up of its business with expansion capital and strategic expertise.

Details of the investment were not disclosed, but T2Y said it is focused on investments in the double- to triple-digit million-euro range — both via the fund and through co-investments.
T2Y, which will also take a seat on Prime’s board, said the goal of the partnership is to increase Prime’s installed production capacity from an existing 300 MWh to more than 8 GWh by 2030.

Founded in 2016, Prime develops advanced battery systems for mobility, industrial, renewable energy storage and grid applications.

The company produces all components from battery cells to battery management systems and offers turnkey energy storage solutions for a variety of industries.

T2Y’s MD of investments, Benedikt Friedrich, said Prime is a ‘hidden champion’ in the energy sector.

Vicentiu Ciobanu, Prime’s CEO, said: “We can now further scale up our production capacity. T2Y Capital’s support reinforces Prime’s position as a leading lithium ion technology provider in Europe, bringing innovative solutions to the market.”
