Battery Energy Storage: How It Works, And Why It’s Important

Energy storage plays a crucial role in the decarbonization of the power system and the mitigation of greenhouse gas emissions. It is fundamental to establishing resilient, reliable, and cost-effective electricity grids capable of managing the intermittent nature of renewable energy sources such as wind and solar. While various energy storage solutions exist, lithium-ion batteries currently stand as the preferred technology, thanks to their cost-effectiveness and high efficiency.

What are Battery Energy Storage Systems / BESS?

Battery energy storage systems (BESS), are devices that enable energy from renewables, like solar and wind, to be stored and then released when the power is needed most.

Battery Energy Storage Systems, or BESS, are rechargeable batteries that can store energy from different sources and discharge it when needed. BESS consist of one or more batteries and can be used to balance the electric grid, provide backup power and improve grid stability.

How Battery Energy Storage Works

At its essence, a battery functions by storing electrical energy in the form of chemical energy, which can subsequently be released as electricity on demand. The process of charging a battery involves converting electrical energy into chemical energy, and discharging entails the reversal of this process. Battery energy storage systems efficiently manage the charging and discharging of energy, often employing intelligent and sophisticated control systems to provide power when needed or most cost-effective. The typical components of a battery energy storage system include a battery system, power conversion system or inverter, battery management system, environmental controls, a controller, and safety equipment such as fire suppression, sensors, and alarms.

The Importance of Battery Energy Storage

Battery storage plays a pivotal role in the energy landscape for various compelling reasons. It aids in the integration and expansion of renewable energy sources, diminishing dependence on fossil fuels. By storing surplus energy generated during peak renewable periods, such as sunny or windy intervals, it addresses the intermittency challenges linked to renewable resources. Additionally, battery energy storage contributes to grid stability and resilience by swiftly responding to fluctuations in grid demand and supply.

Here are some of the key factors underscoring the critical importance of battery energy storage:

Enabling Renewable Energy

As mentioned earlier, renewable energy sources such as wind and solar are intermittent, generating power only when the wind blows or the sun shines. The timing of these energy production periods doesn't always align with peak energy demand. A battery energy storage system (BESS) allows for the storage of excess energy during high production periods, which can be utilized during periods of elevated demand. The integration of renewable energy with storage facilitates a more substantial reliance on renewable sources.

Grid Resiliency and Reliability

As we transition toward a renewable energy future, our electrical grid must adapt to accommodate increased variability and decentralization. A BESS plays a crucial role in stabilizing the grid by absorbing surplus power during high production periods and releasing it during periods of heightened demand. Employing a BESS in this manner can mitigate blackouts and foster a more consistent power supply for the grid. This resilience becomes particularly vital during extreme weather events, which are becoming more prevalent worldwide.

Energy Self-Sufficiency

At a more localized scale, a BESS empowers homes and businesses with solar panels to store surplus energy for consumption during periods when the sun is not shining. Employing a battery energy storage system in this manner promotes energy self-sufficiency, diminishing dependence on the grid and subsequently lowering emissions linked to energy production and transmission.

Battery energy storage proves indispensable in enabling renewable energy, fortifying grid reliability, curbing emissions, and bolstering efforts toward achieving Net-Zero goals. With increasing industries adopting electrification and the escalating demand for electricity, the necessity for battery energy storage is poised to rise.

Conclusion

In conclusion, battery energy storage is a transformative technology that plays a pivotal role in shaping the future of energy systems. Its ability to store and release energy efficiently addresses the challenges posed by renewable energy intermittency and contributes to grid stability and reliability.
