What is a Bess system?

The BESS system is designed to store electrical energy in batteries and manage its use efficiently. Unlike a conventional battery, a BESS system not only includes batteries, but also components such as inverters, transformers, and an EMS (Energy Management System, which is control software).

What are the benefits of a Bess system?

Economic savings: BESS systems can reduce electricity bills by up to 35% by optimizing consumption during peak hours and reducing demand peaks. Power backup: BESS systems can guarantee operational continuity by storing energy that can be used when the power grid is not supplying power to the customer.

Do Bess products need an external power supply?

Most BESS products on the market require an external power supply circuit for their auxiliary loads, although some have built-in circuits and do not need an external supply.

Does Bess require uninterrupted power?

Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation. BESS fire safety standards, such as NFPA 855, outline minimum requirements for backup power for fire safety systems.

Why do companies need a Bess system?

Sustainability: By charging batteries during off-peak hours, when energy is generated using cleaner technologies, and discharging them during peak hours, when more polluting sources are used, BESS systems help reduce companies’ carbon footprint.

What auxiliary loads are needed for a Bess project?

Fire safety systems, such as fire alarms, control panels and gas ventilation systems (if present). These auxiliary loads are essential for ensuring the safe and efficient operation of BESS projects. Therefore, providing a reliable power supply for these auxiliary loads is crucial.
