A new battery energy storage facility has entered operation in Baja, a city in southern Hungary. The project adds to the country’s expanding renewable energy infrastructure. It is connected to an existing generation asset at the same location.
Project developer and installed storage capacity
The facility was developed by Merital Vagyonkezelo. The storage system has a total capacity of 3 MWh. The investment is reported at approximately €1.55 million.
Integration with solar generation and grid injection limits
The battery installation is integrated with a solar power plant located at the same site. The solar plant has an installed capacity of 1.8 MW. The system is designed to store excess solar electricity during periods when grid injection is restricted.
By capturing surplus output, the installation reduces waste associated with curtailed generation. It also supports more stable energy delivery by shifting stored electricity to times when injection constraints apply.
Participation in Hungary’s balancing market
In addition to its solar integration role, the facility will participate in Hungary’s balancing energy market. It will do so in the automatic frequency restoration reserve segment, aFRR.
The battery’s aFRR participation is intended to support grid stability by responding to short-term fluctuations in electricity supply and demand.
Recovery and Resilience Plan financing
Financing for part of the project was provided through Hungary’s Recovery and Resilience Plan. The facility received around €600,000 in non-refundable EU funding.
This support is linked to energy transition investment activity in the region under the plan.
