The Hungarian energy sector is witnessing a significant development with the state-owned energy group MVM launching a new utility-scale battery energy storage system at the Tiszaújváros energy complex. This project aims to enhance grid flexibility and improve the balance of electricity generation, crucial as renewable energy sources continue to proliferate. The facility will provide a capacity of 31 MW and feature 62 MWh of storage, contributing to the stability of Hungary’s national power system.
Valued at approximately €26 million, this investment is being supported through the Recovery and Resilience Facility, an initiative co-financed by the European Union and the Hungarian government. Notably, around €10.8 million of this funding comes from non-repayable EU grants, significantly alleviating financial pressures associated with the project’s execution.
The new battery system will utilize lithium-ion technology and will be installed in modular container units. It is designed to operate alongside an existing battery facility at Tiszaújváros, thereby enhancing the overall storage capacity of the site. Although these two systems are technically independent, they share a common goal of stabilizing the power system amid increasing renewable generation.
In addition to the battery storage initiative, Tiszaújváros is also set to host a major combined-cycle gas turbine power plant with an anticipated capacity of around 1,000 MW. While both facilities will function independently, MVM considers them complementary assets that will collectively improve network responsiveness and facilitate the integration of variable renewable energy sources into Hungary’s energy mix.
All necessary permits, grid connection agreements, and technical requirements have been secured for this project, allowing construction to commence without delays. MVM aims for the battery storage facility to be fully operational by June 2026, marking a pivotal advancement in Hungary’s ongoing efforts to modernize its energy infrastructure.
