National football stadium

High-capacity battery storage brAIn

Delivery point: National football stadium, Bratislava

After installation of a flexibility brAIn system for regulating heat pumps at the National football stadium (NFŠ), the main energy manager and electricity supplier Slovenské elektrárne - energetické služby (SEES) decided to also implement a smart battery storage brAIn by FUERGY with a capacity of 432 kWh.

This project was carried out in two stages. First, heat pumps with a capacity of 3150 kW were equipped with the brAIn flexibility system, which automatically increases or decreases their output as needed, thus providing uncertified ancillary services without limiting the supply of heat and cooling to the stadium.

SEES then decided to install a brAIn smart battery storage, which efficiently shifts the production and consumption of electricity over time according to the needs of the stadium and the national power grid. The system also provides uncertified ancillary services.

During installation, it was necessary to reinforce the floor with a metal structure to support the more than 7-ton device. For this project, we also installed a special cooling system, which was placed on the rear side of the storage unit across its entire width.

Collaboration with the electricity supplier Slovenské elektrárne - energetické služby continues in the management and maintenance of the storage unit. The smart battery storage, along with the brAIn flexibility service for heat pumps, contributes significantly to CO₂ emissions savings.
