Three locations. 12.7 MWh. Approximately 6 MW of power. One energy concept.
In the Košice Region, we have completed and commissioned a project comprising three battery storage systems developed simultaneously in Kysak, Barca and Košické Olšany.
From the very beginning, the entire project was designed as one coordinated energy system. Although the individual battery storage systems are located at three separate sites, together they form a solution with a unified control logic and a shared energy concept.
The result is a battery infrastructure with a total capacity of 12.7 MWh and approximately 6 MW of power, based on Huawei technology.
Why three locations instead of one
One of the main specifics of the project was the available grid connection capacity.
When designing large-scale battery systems, the size of the site or the required battery capacity is not the only decisive factor. The possibility of connecting to the distribution grid, the available power at a specific connection point and the technical conditions of the individual locations all play a crucial role.
The available capacity of the connection points was one of the reasons why the project was developed across three separate locations. At the same time, the sites are geographically close to each other and were designed from the outset to operate as one coordinated energy system once completed.
This approach made it possible to use the available infrastructure more efficiently while creating a solution with significantly greater flexibility than three mutually isolated battery installations.
Technical solution
The project uses Huawei technology with a total capacity of 12.7 MWh and approximately 6 MW of power.
The solution consists of more than just the battery containers themselves. The complete system also includes the power conversion section, transformer stations, communication infrastructure and control systems that enable the coordinated operation of the individual technological units.
An important part of the overall solution is the EMS, Energy Management System, which connects the individual technological components and makes it possible to manage energy flows, optimise the operation of the battery systems and respond to the current requirements of the energy system.
In large-scale battery projects, control is just as important as the battery capacity itself. A capacity of 12.7 MWh alone does not yet create commercial value. The value is created by the way this capacity is managed and utilised.
Complexity of implementation
The simultaneous implementation of three battery storage systems placed significantly higher demands on the coordination of construction, technical and logistical activities.
Earthworks, foundation preparation, infrastructure installation, transportation of technological units, connection works and subsequent system integration were carried out simultaneously at the individual sites.
Each location also required its own power evacuation solution, its own infrastructure and coordination with the energy system. The project was therefore not merely a matter of supplying technology, but primarily of precisely managing the interdependencies between the individual stages of implementation.
The transportation and installation of the battery containers also represented a significant logistical challenge. With these technologies, the weight of individual containers ranges approximately between 30 and 50 tonnes, requiring suitable access roads, handling equipment, crane technology and a precisely planned installation process.
From technology to an energy asset
A modern battery storage system is no longer simply a device used to store electricity.
It is an asset that, depending on the selected business model, can take advantage of market price differences, support the management of energy flows, provide flexibility and participate in balancing services.
For this reason, projects of this type require the right combination of technology, proper design, control and subsequent operational optimisation. A battery storage system must be designed from the outset not only to function technically, but also to make long-term sense from both an operational and investment perspective.
Result
The project in the Košice Region is now fully completed and operational.
Across three locations, a shared battery infrastructure has been created with the following key parameters:
3 locations
12.7 MWh total capacity
approximately 6 MW total power
Huawei technology
coordinated energy concept
control through energy management
The three separate sites therefore do not represent three isolated projects. They operate as part of a single energy concept designed for the active use of energy storage and flexibility.
What this project demonstrates to investors
Large-scale battery projects are not only about the number of MWh.
What matters is the availability of grid connection capacity, the correct selection of locations, technical design, logistics, installation quality, safety, system control and the ability to connect all components into one functional whole.
The project in the Košice Region demonstrates that even extensive battery infrastructure can be developed as a coordinated solution across multiple locations.
For investors, this means one thing. They are not simply investing in batteries. They are investing in energy infrastructure designed to work with energy as an asset over the long term.
From design to operation
At PV SERVICE PLUS, we specialise in the implementation of large-scale energy projects from the initial design through to commissioning.
We provide solution design, implementation coordination, technology supply and integration, commissioning and subsequent optimisation of the energy system.
For us, the Košice Region is not simply another battery technology installation.
It is a reference project demonstrating what modern energy infrastructure can look like in practice when battery storage, intelligent control and a properly designed grid connection are combined.

What our customers say
Thank you very much for the good cooperation in securing the PV system at our home. The money - the subsidy is in our account. You and the company PV Service Plus deserve great praise for the good and quality work.
I will be happy to recommend this company further. I wish you lots of luck and many orders, and may you continue to do well.
Iva, Ratíškovice
Implementation: PV system with a capacity of 5.52 kWp with battery storage of 10.65 kWh with Wallbox
Everything went according to agreement. Based on the agreed criteria, they prepared a price offer, and it remained unchanged throughout the entire implementation phase. Everyone was very helpful, and they managed to resolve small complications during the installation, including placing the panels on the roof according to our wishes.
After granting power of attorney, they handled the subsidy and paperwork. After almost a year of operation, everything works as it should, so far we are satisfied.

Implementation: PV system with a capacity of 7.36 kWp, 16 panels, GodWe ET 10 kW inverter, Pylontech 9.36 kWh batteries
Yesterday I found out that I received a subsidy from the State Environmental Fund of the Czech Republic covering 50% of the costs. This means that the construction of the PV system at my place can be considered successfully completed. The positives definitely outweighed any negatives, so I thank you very, very much. Please extend my thanks to everyone involved in the project.
I wish the company PV SERVICE PLUS success, growth, and that it builds its competitive advantage on expertise and flexibility.

Thank you for the exemplary communication from the administrative department of PVS, especially to Ms. Drahuška, for ensuring that everything went as agreed. We were negotiating the power plant installation for about a month.
The boys installed the panels in two days, and the following weekend the electricians came and connected the power plant. Thank you to them, and I wish you all wonderful days.
