The global energy landscape is undergoing a major shift, driven by the goal of making sustainable energy sources a significant player in the overall energy supply chain. The Battery Energy Storage System (BESS) redefines how energy is stored and distributed. This impacts the functionality, reliability, and the future of energy storage. Westphal is an expert in the design, planning, and implementation of Battery Energy Storage Systems on a large scale. Our recent 96-battery project supports 80,000 residential homes for four hours. The benefits of solar and wind installations are now enhanced by the ability to create a more reliable energy delivery.
What is a Battery Energy Storage System?
A Battery Energy Storage System (BESS) is designed to store electrical energy in batteries allowing for later access and reliable delivery. By capturing excess energy generated during periods of low demand, BESS can release it during peak usage or when generation is insufficient. This capability is essential for balancing supply and demand, improving grid stability, and integrating renewable energy sources like solar and wind, which are inherently intermittent.
Components of a BESS
BESS Systems are complex but generally, the main components encompass the following:
- Battery Modules: The core of a BESS, these modules store energy as electrochemical potential. Lithium-ion batteries are the most common due to their high energy density, efficiency, and declining costs.
- Battery Management System (BMS): This system monitors and regulates battery’s performance, ensuring safety, longevity, and optimal operation.
- Power Conversion System (PCS): Responsible for converting electricity from direct current (DC) to alternating current (AC) and vice versa, facilitating seamless integration with the grid.
- Energy Management System (EMS): This software optimizes energy use, storage, and distribution based on demand, supply, and economic factors.
- Thermal Management System: Ensures the batteries operate within safe temperature ranges to prevent overheating and enhance efficiency.
Key Applications of BESS
BESS enables the storage of surplus energy generated by renewable sources, ensuring a consistent power supply even when production fluctuates. It also provides frequency regulation and voltage control, improving grid reliability and prevents outages.
Businesses and utilities use BESS to offset energy consumption during peak demand, reducing operational costs. BESS also provides a reliable power source during outages, critical for hospitals, data centers, and other essential services. In remote or off-grid locations, BESS allows for the creation of self-sustaining energy systems.
