  • The BESS optimisation contract marks Photon Energy’s strategic expansion into hybrid asset management

  • The agreement covers the real-time optimisation of energy flows between R.Power’s PV system and a battery in Nehrybka, Poland.

  • Photon Energy will operate as both a balancing responsible party and a provider of ancillary services, enabling participation in multiple energy markets.

Amsterdam/Warsaw – 7 August 2025 – Photon Energy N.V. (WSE&PSE: PEN, FSX: A1T9KW) (the "Group" or the "Company") today announced that its Polish subsidiary Photon Energy Trading PL Sp. z o. o. ("Photon Energy") and R.Power Renewables ("R.Power") have signed an agreement for the optimisation of a hybrid asset – photovoltaic installation and battery energy storage system (PV + BESS) located in Nehrybka, Poland. This project is one of the first hybrid assets in Poland, integrating solar PV and energy storage, and represents an important step toward increasing the flexibility of the national power system.

"R.Power is one of the first companies in Poland to address the issue of negative electricity prices during periods of excess generation in the power system. Photon Energy is excited to offer our expertise to maximise revenue from hybrid assets, co-located projects, and cable pooling energy objects. We believe that these optimisation services benefit not only asset owners, but also the grid and the energy system as a whole. During peak generation periods, energy can be stored in batteries and then discharged back into the grid when generation drops. And because these storage systems are charged with renewable energy sources, they actively support the acceleration of the sustainable transition to low-emission energy sources," said Georg Hotar, CEO of Photon Energy Group.

 

"The Nehrybka system is yet another example of our transformation from a photovoltaic project developer into a next-generation integrated energy company. Our goal is to develop solutions that enhance the resilience and flexibility of the electricity system while supporting the continued growth of renewable energy. The integration of PV with storage is not only a response to changing market needs – it is the foundation of our strategy across Europe," said Katarzyna Suchcicka, Vice President of the Management Board of R.Power.

R.Power is a leading European independent power producer and renewables developer, specialising in utility-scale renewable energy and battery storage projects across the continent.

Under the agreement, Photon Energy will optimise the energy flows within R.Power’s hybrid asset in Nehrybka and between the asset and the grid. The goal of is to maximise revenue generation through applying a multi-market optimisation approach, with participation in both spot and ancillary service markets.

Depending on market conditions, the BESS can be charged either from the PV installation or directly from the grid. Both the PV and BESS capacities can be used to provide ancillary services, or to trade on the Day-Ahead Market (DAM) and Intraday Market (IDM).

Optimising these energy flows in real time requires precise forecasting of spot and balancing market conditions, as well as careful consideration of the technical constraints of the system, every 15 minutes. The challenge lies in determining the most profitable strategy for each part of the hybrid asset.

This level of optimisation is only possible through automation and seamless integration of all key components of the system, including the LFC node, SCADA and PLC systems, and machine learning-based forecasting and bidding tools.

This project marks a significant milestone for Photon Energy as it expands into battery energy storage system optimisation – an essential step in supporting grid flexibility and enabling the wider integration of renewable energy across Europe.

 

Key Facts About the Agreement

 

  • Agreement: Optimisation of a hybrid PV and a battery energy storage system (BESS)

  • Location: Nehrybka, Poland

  • Timing: Agreement signed on 1 July 2025, entering into force on 1 August 2025

  • Scope: Photon Energy will implement a multi-market optimisation strategy, participating in spot as balancing responsible party and in ancillary service markets as balancing service provider

  • Market outlook: Poland is seeing rapid growth in renewable energy, with installed PV capacity expected to reach 26 GW and wind capacity 12 GW by the end of 2025. Hybrid systems like R.Power’s will play a key role in grid stability and maximising the use of clean energy.
