The importance of BESS for energy transition

In the current context of climate urgency and the need to reduce greenhouse gas emissions, the transition to a sustainable energy system has become a global priority. While renewable energy sources such as solar and wind energy have made great strides, energy efficiency and management remain a crucial challenge. Battery Energy Storage Systems (BESS) are rapidly emerging as a key solution to meet the goal and overcome the challenges of integrating renewable energy into the power grid. These systems offer several advantages that make them indispensable in the energy transition process.

This article will explore the key role of BESS in the energy transition.

Let us first explain what BESS systems are by briefly illustrating their function.

BESS systems are container-like devices that allow electricity to be stored and released using batteries. They are designed to store electricity during periods of low demand or when production from renewable sources is abundant, and then release it when demand is high, or production is limited.
This function plays a key role in the energy transition process, as it eliminates several issues. Let’s see them in detail.

Integration of renewable sources

One of the main challenges of renewable energy sources, such as solar and wind power, is their intermittency. Energy production depends on weather conditions and can vary significantly throughout the day or year. BESS parks can play a fundamental role in integrating renewable sources into the energy infrastructure, thank to their above-mentioned main function: storing energy generated during periods of peak production and releasing it when demand exceeds supply. This balances the intermittency of renewable sources, ensuring a stable and continuous supply of energy.

Emission reduction and flexibility

BESS parks not only favor the integration of renewable sources, they also contribute to the reduction of greenhouse gas emissions. By enabling the efficient use of energy, these systems reduce dependence on fossil fuels and promote a low-carbon economy. Furthermore, BESS plants offer operational flexibility, as they can be easily sized and adapted to the specific needs of a given power grid. Such flexibility is essential to manage supply and demand fluctuations and to deal with emergency situations such as blackouts or network outages.

Network stabilization and reliability improvement

The presence of BESS systems in the power grid contributes to its stabilization and improvement of overall reliability. They can provide frequency and voltage regulation services, ensuring consistent power quality and rapid response to load changes. BESS parks can act as energy reserves in the event of grid outages or natural disasters, allowing power supply to be maintained in affected areas.

Promotion of electrification and sustainable mobility

BESS systems are not only relevant for the stabilization of power grids, but also for the promotion of sustainable electric mobility. The use of batteries for energy storage enables the development of charging infrastructure for electric vehicles, making them a real alternative to fossil fuel vehicles. Using the energy stored in BESS batteries to power electric vehicles can reduce the environmental impact of transportation systems.

 

In the current landscape of urgent need to reduce greenhouse gas emissions and mitigate climate change, BESS parks are emerging as key elements in the transition to a sustainable energy system. Integrating renewables, reducing emissions, providing operational flexibility, stabilizing the grid, and promoting electrification are just some of the reasons why BESS systems are indispensable. Europe too realized their importance. In April 2023, the European Commissioner for Energy Kadri Simson during a debate with members of the European Parliament on the role of energy storage in the European power grid, defined BESS as vital to the energy transition.

All of this points to how investing in the development and deployment of such systems is critical to ensuring a safe, clean, and efficient energy future.

Energy transition is already underway, and BESS plays a central role in shaping our sustainable future. A future that Redelfi holds close to its heart, that’s why it is active in the development of sustainable infrastructure of Battery Energy Storage Systems parks in the US.
