We are excited to announce that we have entered into a joint venture agreement with Sun Res Holding aimed at establishing one of Poland’s leading investment platforms in the field of Battery Energy Storage Systems (BESS). The partnership will focus on the development, construction, and operational management of a portfolio of large-scale, standalone energy storage facilities that will support the stability of the national power system and enhance energy independence.
CLARITAS Investments emphasizes that energy storage facilities will generate value not only through participation in the wholesale electricity market and arbitrage strategies, but also through active participation in other market segments:
“Today, energy storage facilities are not only a component of energy security and grid stabilization, but also assets capable of operating and generating revenues from multiple sources simultaneously. This includes both the energy market and balancing and ancillary services markets. The key lies in effectively combining revenue streams and optimizing them across the entire asset portfolio. Therefore, the platform’s goal is not only to develop and construct assets, but above all to monetize them efficiently through advanced commercialization strategies,” says Jakub Kupcu, Country Director Poland / Head of Origination CEE at CLARITAS Investments.
The platform’s business model is based on combining stable, contracted revenues with active market participation and exposure, allowing it to balance financial security with opportunities to further enhance project value through active optimization.
Construction of the first battery energy storage facility is scheduled to begin in the second quarter of 2026.
