A Battery Energy Storage System (BESS) refers to a rechargeable battery system that gathers energy from various sources such as the electricity grid, solar power, or wind energy. To ensure uninterrupted power supply, this system is commonly supported by a diesel genset.
By utilising battery storage technology, the BESS stores energy in its batteries, which can be discharged whenever the need arises. The standby genset is only utilised when the energy generated falls short of meeting the requirements. This method has been proven effective in providing backup power and maintaining a stable power supply.
The advantages of a BESS are as follows:
- Flexibility: It can be easily adjusted in terms of capacity to match changing energy needs.
- Cost-effectiveness: It offers an economical solution for energy storage.
- Environmental friendliness: BESS helps in reducing emissions, thus promoting a greener environment.
Beyond Batteries…
While batteries play a vital role in a BESS, organised in modules to form battery packs, there are additional features to consider.
A battery management system ensures the safety and optimal charging of the system, reducing the risk of fires and other potential hazards. An inverter or power conversion feature is also an integral part of a BESS, as is an energy management system that monitors and controls the flow of energy within the system.
Choose Your BESS
Selecting a Battery Energy Storage System requires a customised approach, considering different battery types available:
- Lithium-ion batteries: These batteries are widely favored, with Fortune Business Insights estimating that around 98 percent of the global BESS market share is invested in lithium-ion batteries. They are lightweight, require low maintenance, possess a high storage capacity, and have a long lifespan. However, they can be expensive and are sensitive to extreme temperatures and overcharging.
- Lead-acid batteries: These batteries are cost-effective and easy to recycle, but they have slower charging capabilities and tend to be heavy.
- Nickel-Cadmium batteries: While inexpensive, these batteries are less efficient and pose challenges in terms of recycling.
Increasing Demand for BESS
BESS finds applications in residential, commercial, and industrial settings, catering to various industries ranging from renewable energy providers and industrial electricity consumers to offshore drilling companies.
The ongoing rise in demand for BESS, as observed by Fortune Business Insights, can be attributed to the global push for low-carbon energy generation in order to reduce greenhouse gas emissions.
As the world embraces sustainable energy solutions, Battery Energy Storage Systems continue to play a crucial role in facilitating the transition towards a greener future.
