Headquarters and store of retail chain

High-capacity battery storage system brAIn

Delivery point: BILLA, Bratislava

BILLA has made no secret of its ambition to improve the energy efficiency of its stores. Its headquarters and flagship store on Bajkalská Street in Bratislava have recently undergone modernisation improvements. The operation opted for our brAIn smart battery storage with a capacity of 108 kWh, which we can further expand in the future. For example, in the case of installation of PV system. This storage also provides non-certified ancillary services that reduce the overall energy costs of the operation and at the same time support the stability of the power grid. The investment in the storage, which BILLA financed itself, should pay for itself within five years and can save up to 73 tonnes of CO2e per year. This represents a reduction in the carbon footprint of the building of around 25%. Not only does it achieve a better ESG score today, but it is also actively contributing to environmental protection and the decarbonisation of the Slovak energy sector.

Office building

High-capacity battery storage system brAIn

Delivery point: Tower 115, Bratislava

Modernization of the building does not have to consume either time or money, simply choose the right solution. The installation of a brAIn interior storage with a capacity of 432 kWh for Tower 115 is a prime example of the transformation of an older office building lacking the possibility to install rooftop solar panels into an energy-efficient, cost-saving and emissions-saving facility.

In this case, it was an installation within the Smart battery storage brAIn as a service model in cooperation with its electricity supplier Slovenské elektrárne – energetické služby. Tower 115 received free battery storage without any worries, while the building is able to save more than 400 tons of CO2 emissions annually. We placed the storage in the basement of the building in a room that used to be a warehouse. Despite the use of non-flammable LiFePO4 batteries, we also equipped the room with a modern aerosol fire extinguisher. A professional cooling system takes care of temperature control.

Customer's total costs: EUR 0 under the Energy as a Service model.

Shopping mall

High-capacity battery storage system brAIn

Delivery point: Shopping mall, Martin

Our first, entirely indoor battery storage brAIn is now located in the Galéria shopping mall in Martin. It has a capacity of 108 kWh and was installed in cooperation with the energy supplier Slovenské elektrárne - energetické služby through the Smart battery storage brAIn as a service model.

The Galéria received the battery storage brAIn completely free of charge, and at the same time, receives a part of the revenue generated, thereby reducing its total energy costs.This is done by brAIn’s efficient management of electricity consumption from the power grid. In addition, the Galéria no longer has to purchase expensive certificates of origin of electricity from green sources. The brAIn storage reduces the shopping center's carbon footprint, by up to 28% annually, even without solar panels.

This time we also utilized the residual heat from the batteries, which our system blows into a previously unheated corridor, while cold air is drawn into the battery storage room to cool the batteries. This extra adjustment increased the energy efficiency of the entire solution and at the same time, improved the work environment for Galéria shopping mall employees.

Automotive plant

High-capacity battery storage system brAIn

Delivery point: Hanon Systems Slovakia, Ilava

We installed a smart battery storage brAIn with a total capacity of 864 kWh for the Ilava company Hanon Systems Slovakia, which manufactures air conditioning equipment for the automotive industry. The battery storage was designed according to the company’s diagram of electricity consumption and production from rooftop solar panels which have an installed capacity of 499,5 kWp. The battery installation did require a few custom modifications. In order to get as close as possible to the main switchboard without blocking a nearby access road, we stacked two container storages with a capacity of 432 kWh and connected them by a special walking platform with retractable stairs.

The storage helps to use the energy produced from the solar panels to the maximum extent, earning a profit by providing so-called non-certified ancillary services and saving CO2 emissions as well. Hanon Systems Slovakia obtained solar panels for operating lease and the brAIn smart battery storage for rent from its energy supplier, Slovenské elektrárne – energetické služby, s.r.o., through the Energy as a Service model. The company receives additional rental income, unrivaled electricity supply conditions and a number of other benefits in exchange for the possibility to regulate its electricity production and consumption on site.

Automotive plant

High-capacity battery storage system brAIn

Delivery point: Eissmann Automotive Slovensko, Holíč

Eissmann Automotive Slovakia, a manufacturer of interior accessories for the automotive industry with an annual electricity consumption of approximately 5.5 gigawatt hours, decided to optimize its costs. For this, she used our brAIn battery storage, financed by the energy supplier Slovenské elektrárne - energetické služby. The storage with a capacity of 432 kWh in the exterior version generates a financial effect thanks to the correctly timed charging and discharging of the batteries. Part of this effect belongs to Eissmann in the form of an annual fixed bonus for providing the possibility to regulate their energy consumption. The amount of the bonus increases after five years. Correct timing of energy consumption also prevents CO2 emissions. Thanks to our solution, Eissmann is able to save approximately 400 tons of CO2(e) emissions annually, which it can also report as part of its ESG reporting. The customer doesn't care. All actions such as permits, requests, installation, management, service, and storage maintenance are under the direction of FUERGA and the energy supplier.
