Large-scale battery storage

Large-scale battery storage captures peak consumption, stores renewable energy and provides grid stability. These large-scale battery storage systems are designed for companies, industries and energy hubs that face rising energy demand and challenges such as grid congestion. By storing energy smartly, you create flexibility and work toward an emission-free future.

What is large-scale battery storage?

Large-scale battery storage is a technology in which large amounts of electricity are temporarily stored in high-performance batteries. The goal is to make renewable energy such as from solar panels or wind turbines available at times when demand is highest. This is how you resolve imbalances between production and consumption. Where traditional energy supplies depend on fossil fuels, large-scale energy storage offers a cleaner and more reliable alternative. Want to better understand the basics? Then read our article energy storage system.

How does large battery storage work in practice?

A large battery storage system usually consists of lithium-ion batteries coupled with powerful inverters and a smart energy management system (EMS). This allows energy to be stored when there is a surplus and fed back when demand increases. Often the systems are integrated with solar farms, wind farms or as backup at industrial sites. Here, a battery container provides a scalable and flexible solution that can be deployed quickly.

Benefits and applications of large-scale energy storage

The benefits of large-scale battery storage are manifold. You reduce dependence on fossil fuels, create cost savings and contribute to a more sustainable energy system. Plus, you avoid penalties or delays due to peak load or grid problems. Consider applications such as:

  • Business parks that form their own power hub.
    - Construction sites that need to run emission-free, as we explain in our article on the emission-free construction site.
    - Data centers and hospitals that need emergency power.
    - Events where noiseless, emission-free power is desired.

For business owners, this also means more control over energy costs and a positive contribution to the energy transition. Want to know more? Read our blog on battery storage for businesses.
