A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition fr
BESS can act as a reliable backup power source during grid outages. The stored energy in the batteries is readily available to power critical telecom equipment, ensuring uninterrupted

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).
BESS systems have a wide range of applications in different industrial and energy sectors. The best candidates for implementing these systems in Mexico are companies with electricity bills exceeding 400,000 pesos per month (GDMTH, DIST, and DIT rates).
And when combined with UPS, they can do so with automatic transfer, meaning no interruption in power supply. Improved power quality: By filtering the energy passing through the system, BESSs ensure greater stability and quality in the power supply, which is crucial for sensitive industrial operations. They also help to comply with the Grid Code.
The system is built of two main blocks. The PCS building block, responsible for the main control of the mobile BESS. The nominal power rating of the PCS block is 225 kVA, with a maximum peak power in the peak shaving mode of 275 kW . The second block is the modular battery pack.
