Battery energy storage system

In addition to batteries, accumulators, and lighting products, we also offer battery energy storage systems for various markets. This includes the residential, commercial, and industrial markets. Elfa has the expertise and experience to create custom systems tailored to your preferences.




What do we exactly mean by battery energy storage?

Battery energy storage refers to the process of capturing and storing energy for future use. This involves capturing and storing energy from various sources, including energy generated from solar panels.


Battery energy storage systems are highly significant as they help improve the availability and reliability of energy. They enable us to gather energy when demand is low and energy sources are abundant. Additionally, we can utilize this stored energy during times of high demand or when energy sources are not immediately available.


Energy requirements can vary based on different target groups. We make the following distinctions:

Renewable energy generation system


With a battery energy storage system for residential use, we mean storing energy in homes or households for personal consumption. It allows homeowners to store energy generated by renewable energy sources, such as solar panels.


Battery energy storage systems are increasingly being installed in households due to:

  • The growing demand for electricity
  • The reduction of net metering incentives
  • The lower costs of energy generation through the use of solar panels


Residential energy storage solutions employ battery technologies to store electrical energy. When solar panels produce more energy than the household currently consumes, the excess energy is stored in batteries instead of being sent back to the grid.


Energy storage for residential applications offers several benefits:

  • It can help increase the self-consumption of solar energy, resulting in lower energy bills and reduced reliance on the grid
  • It provides backup power during outages, allowing households access to electricity even when the network is unavailable
  • It contributes to a more sustainable lifestyle by efficiently harnessing renewable energy sources and reducing greenhouse gas emissions


Residential energy storage solutions vary in size and capacity based on the household’s energy needs. Battery systems based on lithium-ion batteries are popular due to their high energy density and long lifespan. These systems are typically integrated with solar panels and can be managed and optimized using smart energy management systems. Saltwater batteries also have excellent characteristics for energy storage systems.

Commercial or business establishments, just like the residential sector, utilize energy storage. Here, obtained energy is used for internal consumption. Commercial battery energy storage systems often employ battery technologies to store electrical energy. They can be integrated with solar energy systems or other renewable sources to store generated energy and use it during periods of higher energy demand than immediate production.


The benefits of energy storage for commercial applications are similar to those for residential use:

  • They can help maximize the self-consumption of renewable energy, leading to reduced energy costs and decreased reliance on the electrical grid.
  • They can manage peak loads even when you don’t have a connection for them.
  • It also provides backup power during outages, enabling businesses to continue operating and minimizing operational disruptions. Furthermore, it contributes to more sustainable business practices and reduces the ecological footprint by efficiently harnessing renewable energy sources and cutting greenhouse gas emissions.


The selection of energy storage solutions for commercial applications varies based on specific energy needs and the scale of the business. Battery systems, such as lithium-ion batteries, are often chosen for their high energy density and reliability.

Unlike residential and commercial sectors, industrial storage applications are used for various purposes, not solely for internal consumption. These purposes include:

  • Peak shaving
  • Demand response
  • Integration of renewable energy
  • Emergency power supply
  • Grid independence
  • Environmental sustainability
  • Large-scale battery storage


The different purposes will be explained in detail.


Peak shaving

Peak shaving is a significant concern for businesses, as high demand during peak hours can lead to increased electricity costs and strain on the electrical grid. Battery energy storage systems enable you to reduce those peak moments, thereby lowering electricity costs and enhancing grid stability. By storing excess energy during off-peak hours and using it during peak periods, savings can be achieved on energy bills.


Demand response

In today’s dynamic energy landscape, it’s essential for businesses to participate in demand response programs. These programs offer financial incentives to reduce electricity consumption during periods of high demand. Through battery energy storage systems, participation in demand response initiatives can be achieved, allowing you to optimize your energy consumption and generate additional revenue. This also contributes to the stability of the electrical grid.


Integration of renewable energy

The global transition to renewable energy sources is gaining increasing momentum. By combining renewable sources such as solar energy or wind energy with battery systems, you can store excess energy generated during favorable conditions and utilize it when demand is high or when renewable sources are less available. This ensures a more reliable and consistent energy supply while reducing dependence on traditional fossil fuel-based energy generation.


Emergency power supply

Unexpected power outages can disrupt operations and lead to significant financial losses. However, there are battery energy storage solutions with reliable emergency power supply that seamlessly kick in during emergencies, ensuring uninterrupted operations and safeguarding critical equipment.


Grid independence

Steering your energy future is of paramount importance. A high-quality battery energy storage system helps achieve grid independence. By generating and storing your own electricity through renewable sources, reliance on the electrical grid can be reduced, along with minimizing the risk of power outages. There is also the potential to become self-sufficient in terms of energy. The systems used for this purpose often incorporate advanced technologies with greater capacities to meet the energy demands of industrial processes.


Environmental sustainability

Energy storage solutions can promote environmental sustainability. With a battery energy storage system, businesses can take significant strides in:

  • Reducing their ecological footprint
  • Limiting greenhouse gas emissions
  • Actively contributing to a more environmentally friendly future


Large-scale battery storage

Through large-scale battery storage, industrial facilities can utilize extensive battery systems with high capacity to store energy and release it when needed. Elfa has installed a large-scale battery storage system at Roompot. For this project, Elfa, in collaboration with several partners, delivered a battery energy storage system for 85 holiday homes.


Within the industrial market, energy storage solutions can be used in most sectors, like:

  • Telecom
  • Utilities
  • Oil and gas
  • Railway
  • Mining
  • Transportation
  • Maritime
