Legal, technical and fire safety
requirements for energy storage
systems of various capacities.
01. POWER CLASSIFICATION
Grid connection requirements for energy storage systems up to 50 kW
Energy storage systems up to 50 kW require only a notification of system update to the grid operator. Installations above 50 kW and large-scale energy storage systems require an application for grid connection conditions as well as a building permit.

02. FIRE SAFETY
Fire protection requirements
Lithium-ion batteries must be installed outside rooms located below ground level with direct external access. The inverter must include an active AFCI function to ensure maximum safety.

03. ENERGY STORAGE TECHNOLOGIES
Technological solutions for energy storage systems
We offer Li-ion electrochemical batteries, lead-acid batteries and pumped-storage hydropower systems. Each technology is selected according to the specific needs and site conditions of the project.

ENERGY STORAGE POWER CLASSIFICATION
Systems up to 50 kW require only a notification to the grid operator. Installations above 50 kW
require an application for grid connection conditions, while large-scale energy storage
systems require a building permit.
ENERGY STORAGE SYSTEMS UP TO 50 kW
Grid connection requirements for energy storage systems up to 50 kW
Solutions for microinstallations require only a notification to the grid operator. The process is quick and does not require complex formal procedures.

ENERGY STORAGE SYSTEMS ABOVE 10 MW
Grid connection requirements for energy storage systems above 10 MW
Large-scale energy storage systems require a building permit. The procedures are more complex and require cooperation with local authorities.

FIRE SAFETY OF ENERGY STORAGE SYSTEMS
Fire safety is essential for every energy storage system. Technical requirements
must be met regardless of the installation size.
