Battery Energy Storage Systems (BESS): An integral part of the sustainable energy revolution?

Battery Energy Storage Systems (BESS) are systems that are used to store energy, which is usually generated from renewable sources. These systems serve as a temporary storage facility that is used in critical situations with less available energy. Photovoltaic systems are an example of this: during the day, they produce the energy that can be easily used by the grid during the day. However, on bad weather days or at night, for example, this is not possible in the required quantity, which is why other energy sources have to be used. With a BESS, the surplus energy generated during the sunny day is then stored in 40-foot containers full of battery blocks and made available to the grid via transformers and can be used on bad weather days or at night. The installation is comparatively simple, requiring a compacted, gravelled area, a small concrete foundation or fragments and the grid connections. Once this has been prepared, prefabricated containers of various sizes and numbers can be delivered, installed and put into operation in good time. BESS thus avoids the need to fall back on less sustainable energy sources and makes the operation of photovoltaic or wind systems significantly more effective. Such systems are not only used in large companies, but also in private households. In other regions of the world, the use of battery energy storage systems is not about avoiding non-ecological energy sources, but about securing operation through reliable systems. In many parts of the world, for example, it is common having electricity outages from time to time, and here too BESS can be a part of the life of social institutions, companies and private households! In my view, this is a great opportunity to move ever closer to the energy revolution!
