Alteo has made a significant advancement in its energy storage capabilities by commissioning a new battery energy storage system in Győr, Hungary. This facility, with a capacity of 20 MWh, operates in conjunction with an existing gas-fired power plant, optimizing the use of grid connection capacity through effective integration with current infrastructure. The development underscores Alteo’s commitment to enhancing grid flexibility and energy balancing.
This project is part of a broader investment initiative backed by Hungary’s Recovery and Resilience Plan, which has facilitated funding for various battery storage projects across Alteo’s subsidiaries. The Győr facility was implemented by Alteo-Therm and represents a total investment of approximately €7.4 million, which includes €2.4 million in non-repayable grants.
Strategically located next to multiple gas engines, the new storage system is designed to leverage existing operational infrastructure for improved performance. Beyond bolstering electricity supply and contributing to grid stability, the facility also plays a role in providing district heating services across several cities, thereby supporting a more resilient and diversified energy system.
With the addition of this facility, Alteo’s total aggregated storage capacity has now reached 90 MW. This expansion follows earlier developments, including a 50 MW system launched earlier this year in Győr and a subsequent 10 MW installation in Bana. These initiatives reflect the company’s ongoing investment in storage technologies aimed at enhancing network reliability while facilitating the integration of a growing share of renewable energy into the grid.
