ENERGY STORAGE
What is BESS?
BESS, or Battery Energy Storage System, stores electrical energy for use when it is needed most.
BESS can be integrated with a solar park, a company electrical system or other energy infrastructure.
Storage is not only about holding energy; it makes the whole energy system more flexible and controllable.

BESS BENEFITS
Why add battery storage to your energy system?
02
Balance generation and demand
Battery storage helps align energy generation with consumption.
03
Manage peak loads
Use stored energy during peak-demand periods to manage system load.
04
Integrate more renewable energy
BESS makes solar generation more flexible and controllable.
05
Optimise energy use
Store and use energy according to the site load profile and system objectives.
06
Prepare for the future
Storage adds flexibility and allows the infrastructure to evolve when needed.
APPLICATIONS
Battery storage for different energy users
Solar parks
Store solar generation and make production more flexible.
Industry
Manage large loads and optimise energy use based on the actual consumption profile.
Commercial buildings
Integrate storage with existing infrastructure and use generated or stored energy more flexibly.
Energy projects
BESS can form part of a wider renewable energy and grid project.
SOLAR PARK + BESS
Solar park and battery storage as one system
A solar park generates energy when sunlight is available, while demand may occur at a different time. Battery storage allows part of the generated energy to be stored and used later.
HeilAres can combine solar generation and battery storage into one integrated energy solution.

Consumption / grid
The right solution depends on generation, consumption, grid connection and project objectives.
Explore solar park solutionsPROJECT-SPECIFIC SIZING
Battery storage must fit the project, not the other way around
Every energy storage project is different. Selecting the right BESS requires consideration of consumption, generation profile, grid connection, required power, storage capacity and intended use.
That is why HeilAres does not offer one standard battery system for everyone.
The solution is selected according to the technical needs of the project.

COMPLETE SOLUTION
A complete battery storage solution
Battery system
A battery system selected for the project’s energy storage needs.
Inverters and converters
Equipment required to control energy flows and system operation.
Control system
Control and optimisation according to the project objectives.
Electrical installation
Cabling, switchboards, protection systems and required electrical connections.
Monitoring
Monitoring system operation and using data to control it.
Grid connection
A solution matched to the site grid connection and technical conditions.
BESS AND ELECTRICAL WORKS
BESS also requires a professional electrical solution
Battery storage is not a standalone device. It must be integrated with the site electrical system, inverters, protection systems, cabling and grid connection.
HeilAres can connect the electrical side of a BESS project with other energy solutions.

Safety and reliability are integral to BESS
Battery storage systems require consideration of the complete technical architecture, electrical safety, temperature conditions, protection systems and fire safety.
Design and installation must account for the specific site, selected technology and applicable technical requirements.

FUTURE-READY ENERGY INFRASTRUCTURE
Plan your energy infrastructure for the next stage
Energy needs change. Future additions may include new solar parks, EV chargers, production equipment, storage or other high-power consumers.
Energy infrastructure should therefore be planned with possible future expansion in mind.
