RGREEN INVEST and Renalfa Solarpro Group have launched Renalfa Power Clusters (RPC), a new joint venture backed by €200 million in equity to finance an €800 million pipeline of hybrid renewable assets across Romania and Poland.

The venture builds on the partners’ earlier platform, Renalfa IPP, which scaled rapidly in under five years by deploying utility-scale renewables integrated with long-duration BESS. The model enabled the platform to deliver green baseload power products, combining intermittent renewable generation with dispatchable storage.

The key signal is capital backing merchant-exposed hybrid portfolios rather than purely contracted renewables. By pairing generation with long-duration storage, the sponsors are underwriting a structure capable of stabilizing output and monetizing price volatility without relying entirely on policy-driven support.

Commercially, this reflects how storage is shifting from an ancillary asset to the core enabler of bankable hybrid portfolios. Long-duration BESS allows operators to shape renewable output, serve flexible loads such as data centres and low-carbon industries, and capture intraday spreads.

The deal also reinforces a geographic trend. Eastern Europe is emerging as a testing ground for hybrid business models where market volatility, growing electricity demand, and improving regulatory frameworks create conditions for merchant-backed infrastructure.
