French asset manager RGreen Invest and Vienna-based clean energy group Renalfa Solarpro have agreed to establish a new joint venture targeting up to €800 million in hybrid renewable energy investments across Romania and Poland. The platform, named Renalfa Power Clusters, will focus on integrating large-scale renewable generation with advanced storage and demand optimisation technologies.

The partners are committing a combined €200 million in equity to capitalise the new vehicle, with the remaining funding expected to be structured through project-level financing and additional capital sources as developments progress.

Hybrid Projects Combining Generation and Storage

Renalfa Power Clusters will prioritise next-generation renewable configurations that combine solar and wind generation with battery energy storage systems. The strategy emphasises long-duration storage and dispatch capabilities to enhance grid stability and support energy-intensive sectors.

In addition to supplying renewable electricity, the platform aims to deliver demand-side optimisation solutions tailored to low-carbon industrial users and data centres. By pairing generation assets with storage and digital optimisation tools, the venture seeks to improve merchant project economics while addressing intermittency challenges.

The initiative builds on an earlier partnership between the two companies. Less than five years ago, RGreen and Renalfa formed Renalfa IPP, an investor-operator platform focused on utility-scale hybrid renewable assets. The new vehicle extends that collaboration into larger, more integrated cluster developments.

Regional Expansion in Romania and Poland

Romania and Poland have emerged as priority markets due to increasing electricity demand, grid modernisation requirements and accelerating renewable capacity additions. Both countries are experiencing structural shifts in power systems as coal capacity declines and electrification expands across industry and transport.

Renalfa Solarpro operates more than 753 MWp of solar photovoltaic capacity, 89 MW of wind and over 1.5 GWh of battery storage across Central and Eastern Europe. The group currently has more than 2.3 GW of renewable projects and 9 GWh of battery storage under construction or development across Bulgaria, Romania, Hungary, Poland and North Macedonia.

RGreen Invest, through its Infragreen equity funds, has supported more than 3,000 energy transition projects across Europe with a cumulative value exceeding €3.4 billion. Its participation in the new platform reflects a continued focus on hybridisation and storage as core enablers of renewable integration.

Market-Based Electrification and Capital Deployment

Executives from both firms described the initiative as aligned with broader electrification trends reshaping European energy markets. The expansion of batteries and optimisation technologies is increasingly viewed as essential to enabling merchant renewable projects to compete without reliance on subsidy frameworks.

By combining equity capital with operational expertise in engineering, procurement, construction and asset management, the Renalfa Power Clusters platform is positioned to structure hybrid projects capable of operating in competitive wholesale power markets.

As renewable penetration increases across Central and Eastern Europe, hybrid configurations that integrate storage and flexible dispatch are expected to play a growing role in balancing supply and demand. The €800 million investment target signals confidence in both the technical maturity of storage systems and the availability of financing for large-scale merchant renewable infrastructure.
