The Hungarian state-owned energy company MVM is advancing its energy infrastructure with the initiation of a new utility-scale battery energy storage project at the Tiszaújváros energy complex. This project aims to improve grid flexibility and support the stability of electricity generation within the national power system. The facility will provide a capacity of 31 MW and feature 62 MWh of storage capability.
Valued at approximately €26 million, the project is being financed through the Recovery and Resilience Facility, a funding mechanism supported by both the European Union and the Hungarian Government. Notably, around €10.8 million of this total is sourced from non-repayable EU grants, which significantly alleviate the financial burden associated with the development.
The new battery installation will utilize lithium-ion technology and be constructed using modular container units. It will complement an existing battery system at Tiszaújváros, thereby increasing the overall storage capacity at the site. Both facilities are designed to operate independently but are strategically aligned to stabilize the power system as renewable energy generation expands in Hungary.
In addition to the battery storage project, Tiszaújváros is set to host a combined-cycle gas turbine power plant with a planned capacity of approximately 1,000 MW. While these two systems will function separately, MVM considers them as complementary assets that will collectively enhance network responsiveness and facilitate the integration of variable renewable energy sources into the grid.
All necessary permits, grid connection agreements, and technical requirements have been secured, allowing construction to commence without delay. MVM anticipates that the battery storage facility will be fully operational by June 2026, marking a significant milestone in Hungary’s efforts to modernize its energy infrastructure.
