What is happening in the Tiszántúl region is also happening in the Bakony region: a hybrid power plant is being built in Ajka.

MVM Tisza Erőmű Kft. recently announced that it will build a chemical-based energy storage system at its Tiszaújváros site alongside the 1000 MW combined cycle power plant. Now, MVM Balance Zrt. has announced a similar investment: the Bakonyi Gas Turbine Power Plant in Ajka will be supplemented with a 57 MW, 57 MWh battery energy storage system.

Thanks to an investment of more than 10 billion forints, the power plant and energy storage unit will be used to create the Bakony Hybrid Power Plant.

„Thanks to the development of the hybrid power plant, Hungary will see the creation of a pioneering industrial-scale energy storage technology that will result in the coordinated, environmentally friendly operation of the storage facility and the gas turbine power plant's machinery.” – as stated on the MVM website.

Fast response, more stable network

The new energy storage facility is capable of delivering its rated power within a few seconds, thus effectively helping to regulate the electricity system and balance out fluctuations in weather-dependent production from renewable sources. The equipment will be housed partly in containers and partly outdoors, with the electrical connection being made via the power plant's new switch building. Construction is expected to be completed on 30 June 2026, in line with Hungary's green transition goals and the MVM Csoport medium-term strategy.

The investment is being realised with EU support.

The total cost of the project is estimated at HUF 10.4 billion, of which the company has received HUF 3.85 billion in non-repayable EU funding under Hungary's Recovery and Resilience Plan. The development, with a supported capacity of 28.5 MW/57 MWh, will contribute to strengthening self-sufficiency, reducing external energy dependence and reducing greenhouse gas emissions.
