How to correctly judge the advantages and disadvantages of battery energy storage systems? 


Battery energy storage systems (BESS) can help balance the loads of electricity during peak and off-peak times. Depending on the time of day and the season, electricity demands can vary significantly. Higher demand results in higher prices for electricity. Conversely, lower electricity costs can be expected during off-peak hours. By installing a BESS, you can benefit from peak shaving.

What are battery energy storage systems?

Battery energy storage systems are an increasingly popular option for homes and businesses, and their benefits are numerous. A BESS can protect power-quality-sensitive loads against voltage fluctuations and outages. A BESS installed between a utility wall outlet and a personal computer is a frequent example of this use. It serves as an uninterruptible power source (UPS).


In the case of a utility power loss, the BESS will continue to power the computer until the charge on its battery runs out. Furthermore, the UPS battery serves as a sink for a variety of other utility irregularities such as voltage and frequency variations.


Modern battery energy storage systems come with built-in inverters and computerized control systems. This makes them easy to install, maintenance-free, and safe for people. Commercial-scale battery energy storage systems can charge electricity from the grid or solar PV. They also work well for off-grid homes.


Pros of Battery Energy Storage Systems

First, battery energy storage systems can play a vital role in the future of the grid. Because of their interconnected nature, these systems can solve a variety of energy challenges for consumers, producers, and grid operators. Ultimately, these systems could be the catalyst for a clean energy revolution that benefits everyone.


Secondly, energy storage helps reduce energy bills by reducing peak electricity demand. Demand for electricity is often higher at night and during hot summer days, and power plants are forced to ramp up their production. Battery energy storage allows users to store electricity during off-peak hours and use it later when the energy supply is lower. Moreover, battery energy storage is useful in areas that experience frequent power outages.


Another advantage of battery energy storage systems is that they are flexible and can be designed to meet varying power and storage needs. Modern battery technologies are designed for portability, safety, and environmental friendliness. Battery energy storage systems can also be scalable for utilities and industries.


Cons of Battery Energy Storage Systems

However, battery systems are not without their problems.


They need air conditioning systems and systems for storing energy in batteries.


When temperatures are above 20°C, battery life can be cut in half. But a high-quality LiFePO4 cell from BentiEnergy can work continuously at 50 degrees.


Also, the “round trip” inefficiencies result in the loss of energy.


Last but not least, additional expenditures as well as complexities.


Despite their drawbacks, battery energy storage systems are still very promising and have the potential to change energy use for good. We should take a rational standpoint on either side. Many countries are turning to this technology to reduce their dependence on fossil fuels and improve the reliability and resilience of their power systems. It can also help them reach their de-carbonization and environmental targets.
