R.Power secures €30 million in Green Bonds to accelerate battery storage expansion

Solar developer R.Power has formalized terms for a €30 million (USD $32.6 million) secured green bond issuance to fund battery energy storage projects across Central and Eastern Europe, marking another milestone in the Polish company’s continued expansion into the energy storage sector.

R.Power said it signed the bond terms on June 10, with the securities set to be issued on June 26, 2025. The bonds form part of R.Power’s broader PLN 1 billion (USD $272 million) green bond program established in partnership with mBank, as it looks to scale renewable energy infrastructure through green bonds, which are debt securities earmarked for climate and renewable projects.

Green bonds provide specific green funding options for investors, and R.Power’s green bond framework specifically targets battery energy storage systems (BESS) alongside other renewable projects within its capital group.

The six-month Euribor-linked bonds carry a 3.50% margin and will trade on the Warsaw Stock Exchange’s alternative trading system.

The financing comes as R.Power advances storage initiatives across the region. The company recently announced on LinkedIn a “strategic investment” for a 127 MW/254 MWh battery project in Romania, with construction scheduled to begin in Q3 2025 and completion targeted for Q3 2026. The facility will connect to Romania’s transmission grid operated by Transelectrica. R.Power said it secured funding support for the project from Romania’s National Recovery and Resilience Plan, part of the EU’s NextGenerationEU recovery fund.
