Enough Energy to Circle the Earth Contained in 16 Battery Cabinets: E.ON Unveils New Energy Storage Facility in Soroksár
E.ON has commissioned a new energy storage facility in Soroksár to enhance energy network stability and allow the connection of new solar panel systems to the grid. This development was realized through a HUF 784.5 million budget, in part financed by the European Union’s Recovery and Resilience Facility and from E.ON’s own resources.
The energy storage facility is comprised of 16 outdoor battery cabinets, each with a capacity of 344 kWh, for a total capacity of 5.5 MWh and an output of 2.5 MW—equivalent to the daily output of 350 household solar panel systems. That’s enough energy to power an electric car for up to 43,000 kilometres, the same distance to circumnavigate the Earth along the equator. The development will increase the stability of the grid, reduce potential outages due to voltage fluctuations, and indirectly enable the connection of new solar panels.
The new storage facility supports MAVIR (‘Hungarian Transmission System Operator Company’), which manages Hungary’s electricity system, in maintaining network balance by evening out the lag between production and consumption. The advancement aligns with the objectives of the country’s National Energy and Climate Plan, and increases the competitiveness of the economy and its resilience to climate change.
In 2018, ELMŰ Hálózati Kft., part of the E.ON Hungária Group, also installed the country’s first large (10 MW) battery energy storage system with a capacity of 6 MWh in Soroksár. Together with the new battery unit, E.ON’s storage facilities in Soroksár now encompass a total output of 12.5 MW and a capacity of 11.5 MWh, thereby strengthening the integration of renewable energy sources and grid stability.
