Battery Energy Storage Systems (BESS)

Energy Storage for a Modern Power Supply
Battery Energy Storage Systems (BESS) store excess energy from renewable sources such as solar, wind, or hydropower and release it precisely when it is needed. In doing so, they balance fluctuations between energy generation and consumption, reduce the reliance on conventional reserve power plants, and make a significant contribution to grid stability.

Practical Applications and Benefits

Grid Stabilization: BESS compensate for fluctuations and provide additional energy when needed.
Emergency Power Supply: Ensure the supply of critical infrastructure during outages.
Use of Renewable Energy: Provide reliable energy even with fluctuating input from renewables.
Peak Load Management: Reduce peak loads and sustainably lower energy costs.
Grid-forming: Supports grid restoration and stabilizes frequency after outages.
Island Operation: Autonomous energy supply without connection to the public grid.

Types of Battery Storage:

Lithium-Ion (LiCoO₂, NMC, LFP etc.): Fast, long-lasting, and widely used in many applications
Flow Batteries (e.g., Vanadium Redox): Scalable with a long service life
Lead-Acid Batteries: Affordable and compact, but with limited lifespan
