Battery energy storage system (BESS) is responsible for managing the flow of energy, utilizing intelligent and sophisticated control mechanisms. These systems guarantee the availability of power when it is needed most or when it makes the most economic sense. They consist of various components:
- Battery management system
- Battery system
- Environmental controls
- Power converter
- Essential safety features such as alarms, fire suppressors, & sensors
Energy battery storage systems usually have a lifespan of around 5 and 15 years. As a vital component in the array of solutions for the energy transition, these storage systems must not only contribute to sustainability but also exemplify complete sustainability in their own existence.
Working of Battery Energy Storage Systems (BESS)
The fundamental operation of a Battery Energy Storage System (BESS) is simple and works in the following way.
- It takes in electricity from the power grid, directly from a power station, or from a renewable source like solar panels, storing it as a current for later use.
- When integrated with software, a BESS transforms into a platform that combines the storage capacity of batteries with the intelligence derived from AI, Machine Learning, and data-driven solutions.
- This turns batteries into a tool for combating climate change, offering a flexible approach to energy use that adapts to fluctuations in demand and supply.
- In essence, battery energy storage systems promote the integration of renewables, contributing to reduced carbon emissions and potentially lowering costs for businesses and households.
Types of Battery Energy Storage System (BESS)
Battery Energy Storage System (BESS) comes in two varieties, Front-of-the-Meter (FTM) and Behind-the-Meter (BTM).
BTM systems are usually smaller and located on the user’s premises. While their primary role is enhancing the stability and cost efficiency of the owner’s energy supply, they can potentially feed energy back into the grid, serving as an additional revenue source if permitted by local regulations.
On the other hand, larger FTM systems, directly linked to the power grid, and typically owned by utilities, play a crucial role in addressing network congestion challenges or serving as an alternative to constructing new power lines.
Importance of Battery Energy Storage Systems
Battery storage plays a crucial role in the energy landscape for the following reasons.
- It aids in integrating and scaling up renewable energy sources, diminishing dependence on fossil fuels.
- It stores extra energy from sunny or windy days and helps solve the problem of renewable energy being intermittent.
- Moreover, it enhances grid stability and resilience, swiftly adapting to fluctuations in demand and supply.
- It reduces emissions from big plants, promotes electrification, and supports energy independence.
