Battery Energy Storage Systems (BESS)
These systems are crucial for storing renewable energy and ensuring a stable supply.

• BESS solutions enhance grid resilience and ensure renewable energy scalability.
• Enables load balancing, peak shaving, and backup power.
• Accelerates energy transition to 100% renewables.

• LFP, 314Ah cells
• 10 MWh energy capacity
• 5MVA Transformer + 2*2.5MW PCS+MV cabinet
• Liquid cooling system for battery system
• Two 20-foot pre-installing battery containers
• Back-up power, peak shaving, micro-grids, energy arbitration application

The battery energy storage system's (BESS) essential function is to capture the energy from different sources and store it in rechargeable batteries for later use.

Often combined with renewable energy sources to accumulate the renewable energy during an off-peak time and then use the energy when needed at peak time.

This helps to reduce costs and establish benefits for the user. BESS offers flexibility in grid connection and can operate in local mode when the grid is unavailable.

• Renewables – Battery energy storage aligns solar and wind generation peaks with demand peaks.
• Residential and Commercial – lower energy costs, improves load factor, and manages demand peaks.
• Utility distribution grid – balances fluctuating demand at peak hours while reducing grid overload.
• Industrial loads – provides backup power for critical loads, improves load factor, and manages demand peaks.
• Electrification of transportation – reduces demand on the grid and enables fast DC charging without increasing demand charges.

• Technology - Enhanced battery efficiency with improved storage duration. Decentralized technology to help move away from total grid dependence.
• Cost - Benefits from a declining installation cost have made these systems more economical. Plus, added savings through peak shaving and a declining cost in the overall battery system per kWh.
• Environmental - Federal environmental initiatives and tax incentives are key influencers in meeting net-zero clean energy goals by simultaneously helping to move towards more sustainable energy generation.

Battery
The battery is the fundamental element of an electrical energy storage system.

Battery management system (BMS)
The Battery Management System (BMS) ensures and keeps track of the internal performance of the battery cells, system parameters, and potential hazards. The BMS data is internally collected and used to monitor and maintain an optimum level of charge without over changing the battery, helping to prolong the lifecycle of the system.

Power conversion/conditioning system (PCS)
The power conversion system is designed to convert the direct current produced by batteries, or the battery system, into alternating current that can be used for power consumption on the grid. During off-peak time, the PCS takes the energy from the grid to store in the BESS. In essence, the PCS's main function is to convert the power between the energy storage system and the grid, and vice versa. It accomplishes that by offering a bi-directional flow from DC-AC and AC-DC. See how our ABB OEM products flourish here: Download BESS brochure
