What is solar energy storage?
What are the main battery storage applications?
Battery storage can be used in many ways that go beyond the simple emergency backup in the event of an energy shortage or blackout. Applications differ depending on whether the storage is being used for a business or a home.
For commercial and industrial users, there are several applications:
- Peak shaving, or the ability to manage energy demand to avoid a sudden short term spike in consumption
- Load shifting, which allows businesses to shift their energy consumption from one time period to another, by tapping the battery when energy costs more
- Flexibility, whereby customers can reduce their site’s grid demand at critical times – without changing their electricity consumption. Energy storage therefore makes it a lot easier to participate in a Demand Response program and save on energy costs
- Microgrids rely on batteries as a key component, because these grids need energy storage to enable them to disconnect from the main electricity grid when needed
- Integration with renewable energy sources, since batteries guarantee a smooth and continuous electricity flow in the absence of the availability of power from renewables.
Residential users benefit from battery storage applications by:
- Self consumption, since residential users can produce solar energy during the daylight hours and then run their appliances at home at night
- Emergency backup in the event of a blackout
- Going off the grid, or detaching completely from an electrical or energy utility

How does a battery storage system work?
The operating principle of a battery energy storage system (BESS) is straightforward. Batteries receive electricity from the power grid, straight from the power station, or from a renewable energy source like solar panels or other energy source, and subsequently store it as current to then release it when it is needed.
When combined with software, a BESS becomes a platform that couples the energy storage capacity of batteries with the intelligence needed to deliver advanced management of energy consumption by harnessing AI, Machine Learning and data-driven solutions. This makes batteries a tool in the effort to offset climate change, because they enable a more flexible way of using energy that lets the user adapt to dips and peaks in demand and supply. Overall, battery energy storage systems foster the deployment of renewable sources, thereby helping reduce carbon emissions and even deliver lower costs for businesses and households.
Enel X works with businesses to ensure that all the energy needs are met, regardless of whether a facility already has a battery storage system up and running, needs to stall a new one, or must add more capacity. Our battery storage system is equipped with our DER.OS optimization software, which is designed to work with all kinds of distributed energy resources and can easily be integrated into existing systems, such as solar photovoltaic systems.
