Battery Energy Storage System - BESS
A Battery Energy Storage System (BESS) has the potential to become a vital component in the energy landscape. As the demand for renewable energy and electrification grows, a BESS is a reliable source of power that can help reduce emissions, optimize energy costs, and promote a stronger, greener grid.
A BESS works like a large-scale rechargeable battery, storing electricity when it's abundant, often from renewable sources like the sun and wind. In addition to supplying energy for your business when demand is high, a BESS acts as a reliable backup during outages or disruptions. This system provides financial benefits by optimizing energy costs and promotes a greener grid by reducing reliance on non-renewable sources.
Power up while reducing costs
A BESS can store energy when electricity prices are low, like at night or when a lot of renewable energy is generated. Then, during peak hours when prices rise, a BESS can be used to support charging instead of drawing power from more costly sources - potentially reducing your energy bills.
Minimize interruptions
With a BESS, you get a steady and reliable source of backup power. So even if the sun isn't shining, the wind isn't blowing, or an unexpected power outage occurs, a BESS can help ensure your operations maintain a consistent flow.
Earn from excess energy
As well as storing energy, a BESS provides the opportunity to participate in the energy market. During peak hours, surplus energy can be sold back to the grid instead of remaining unused. This transforms excess energy into extra revenue while supporting a greener grid.
What's inside BESS?
A BESS is built on various components that work together to efficiently store, manage, and release electrical energy. Each component has a specific role, contributing to the overall performance and functionality of a BESS.
Batteries
Captures electricity generated from diverse sources, including renewables, and stores it for subsequent release as required.
Inverter
The inverter transforms DC electricity from batteries into AC power commonly used in homes and buildings for various appliances.
Battery management system
Monitors batteries, ensures safe charging/discharging, manages temperature, and maintains overall cell health for efficient performance.
Energy management system
Manages battery charging/discharging and regulates electricity flow to/from the grid for optimal energy utilization and grid stability.
Thermal management system
Ensures optimal operation of the BESS regardless of conditions, equipped with pumps, radiators, active cooling, and a heater.
