BESS
BESS stands for Battery Energy Storage System. It's like a giant rechargeable battery system for storing electricity on a large scale. Companies use these systems to store excess energy when it's cheap or abundant (like during sunny or windy days) and use it later when needed. Think of it as a huge power bank, similar to what you use for your phone, but for entire buildings, factories, or even cities. These systems are becoming increasingly important as more companies move towards renewable energy and need ways to store power for when the sun isn't shining or the wind isn't blowing.
