Greenvolt Power sells Polish battery assets to A&R Investments
Greenvolt Power has agreed to transfer two large battery storage facilities in north-eastern Poland to Malta-based A&R Investments.
Key points
- Greenvolt Power is selling the Ełk and Turośń Kościelna battery storage projects, each rated at 200MW.
- The transaction is scheduled for completion by the end of 2026 pending customary conditions.
- Both sites secured 17-year capacity market contracts starting in 2028 along with a ten-year tolling agreement.
What happened
Power Technology reported that Greenvolt Power has reached an agreement to transfer two operational battery storage sites in north-eastern Poland to A&R Investments, an investment vehicle based in Malta. The transaction involves the Ełk and Turośń Kościelna facilities, which together provide a total power capacity of 400MW and 1.6GWh of energy storage. Each location features 200MW of capacity paired with 800MWh of storage, giving them the ability to operate at maximum output for roughly four hours.
Completion of the sale is anticipated by the close of 2026, subject to customary closing conditions. Christian Buhagiar, a director at A&R Investments, noted that the acquisition supports the firm's portfolio growth within the Polish market. The two sites were finalised in the third quarter of 2026 and hold operational permits. Furthermore, they secured 17-year capacity market agreements beginning in 2028, ensuring fixed revenues for making 85% of their capacity available to Poland's national power network, alongside a ten-year tolling contract to manage market trading.
What comes next
The divestment aligns with Greenvolt Power's broader asset-rotation framework, which targets the sale of 70% to 80% of its internally developed portfolio to recycle capital into new ventures. Weronika Nowak, chief executive officer of Greenvolt Power, emphasized that the Ełk and Turośń installations illustrate the company's capability to take large-scale storage initiatives from conception through to final delivery. The firm maintains an overall development pipeline of approximately 4.6GW of battery storage capacity across its operational footprint.
Why it matters
Large-scale battery deployment is increasingly vital for modernising grid infrastructure and integrating intermittent renewable generation sources. According to World Bank figures from 2021, renewable energy accounted for 17.5% of electricity output in Poland. As energy transition efforts accelerate across Europe and emerging markets, financial structures such as long-term tolling agreements and capacity market contracts provide essential revenue visibility for investors backing capital-intensive storage assets. Policymakers and regulators across developing regions observe such market mechanisms closely to determine how similar regulatory frameworks might eventually encourage private capital mobilisation for grid-scale flexibility and storage solutions.
