A new chapter in national energy supply began on Thursday in the northwestern Hungarian city of Győr. The Alteo Group commissioned its latest electricity storage facility with a capacity of 100 megawatt hours (MWh). It is the largest industrial facility of its kind in Hungary to date.
This project is of considerable importance for the stability of the national power grid. With its commissioning, this storage facility alone covers one-fifth of the country’s total installed storage capacity.
The facility was built as part of Hungary’s Recovery and Resilience Plan (RRF). Alteo invested a total of 18 billion forints (48 million euros) in new lithium-ion storage technologies through three subsidiaries. Of this, approximately 12.9 billion forints (34 million euros) was allocated to the site in the Győr Industrial Park. The project was supported by government subsidies amounting to 6 billion forints (16 million euros), with the sub-project in Győr receiving approximately 4.4 billion forints (12 million euros) in subsidies.
The new storage facility at Alteo-Depónia Kft. has a rated output of 49.9 MW and a capacity of 99.8 MWh.
It is connected directly to Alteo’s smart control center. The main task of the plant is to maintain the system-critical balance between generation and consumption.
“In 2018, we were the first in the region to commission industrial energy storage facilities. With this year’s expansions, our total capacity now stands at an impressive 90 MW,” explained Attila Chikán Jr., CEO of Alteo.
Such large-scale storage facilities are indispensable, especially for the integration of weather-dependent generators such as solar and wind farms.
They buffer production peaks and then release the energy when grid demand rises, significantly increasing the security of supply.
In addition to its technological expansion, Alteo can also look back on a dynamic 2025 financial year. The group, which is listed in the premium segment of the Budapest Stock Exchange, saw its revenue rise by 19% to over 125 billion forints (333 million euros).
Despite the growth in revenue, operating profit (EBITDA) fell short of the record figures of previous years at 16.4 billion forints (44 million euros). The company cited increased competition and the associated shrinking margins in energy management as the reason for this. Alteo is responding to this with an efficiency offensive and further diversification of its portfolio in order to be able to respond flexibly to new market requirements.
Alteo Nyrt. shares remain an important asset on the Hungarian capital market. Last year, the share price fluctuated between 4,130 and 6,880 forints (11 and 18.32 euros), underscoring investors’ continued interest in the green energy service provider.
