Renegia: Shaping the Future of Energy Storage.

At Renegia, we specialize in preparing Battery Energy Storage Systems (BESS) for a range of critical and sophisticated applications, ensuring the resilience and efficiency of energy grids. Our projects are tailored to meet the diverse needs of Frequency Containment Reserve (FCR), automatic Frequency Restoration Reserve (aFRR), manual Frequency Restoration Reserve (mFRR), black start capabilities, and balancing market scenarios.

FCR Projects: We design BESS solutions that contribute to Frequency Containment Reserves, crucial for maintaining the stability of the power grid’s frequency in real-time.

aFRR and mFRR: Our systems are adept at participating in automatic and manual Frequency Restoration Reserves, playing a vital role in restoring and maintaining the grid frequency post disturbances.

Black Start Capability: Renegia’s BESS projects are also equipped for black start scenarios, providing the necessary energy to jumpstart a power grid from a complete shutdown, a critical feature in enhancing grid resilience.

Balancing Market Scenarios: We prepare BESS solutions that can respond effectively to balancing market demands, ensuring the equilibrium between energy supply and demand, and contributing to the overall reliability and efficiency of the energy system.

Renegia Secures Major Win in Polish Capacity Auction with 50 MW Project

Renegia, a leader in the development of Battery Energy Storage Systems (BESS), has achieved a significant milestone in Poland’s energy sector. The company has triumphantly won a capacity auction, securing a project of 50 megawatts (MW). This notable achievement is not just a testament to Renegia’s technical and strategic capabilities in the renewable energy industry but also marks a crucial step forward in Poland’s energy transition.


The BESS technology by Renegia is designed to capture and store energy produced from various renewable sources, such as solar and wind power. This stored energy can then be released when the demand for electricity is high or when the renewable sources are not generating energy, for instance, during the night or on calm days without wind.


Renegia is at the forefront of advancing green transport initiatives through its innovative Battery Energy Storage Systems (BESS). The company’s BESS technology is a cornerstone in supporting the growing sector of eco-friendly transportation, providing sustainable and efficient energy solutions that are crucial for the development of green transport infrastructure.

Ancillary Services

Renegia’s Battery Energy Storage Systems (BESS) are at the forefront of transforming ancillary services in the energy sector. These systems play a critical role in supporting and maintaining the reliability and stability of the power grid, a vital aspect of modern energy infrastructure.

Energy Backup

Renegia’s Battery Energy Storage Systems (BESS) are not only innovative solutions for energy storage but also serve as crucial support for grid stability and emergency responsiveness, including black start capabilities. This ensures continuity in electricity supply, mitigating the impact of power outages.
