HOME | Battery Energy Storage Explained.

Batteries storage systems come in varying sizes and can be modular so you can have more than one working together, storing more electricity.

They are particularly useful if you are generating your own electricity e.g. rooftop solar. So, your solar can generate zero-carbon electricity during the day when you are at work and the battery allows you to store the free electricity and discharge it in the evening when most people need it.  This can help you cut your reliance on the national grid and can make you self-sufficient using only home-grown green electricity.

Even if you do not have your own renewable generation, you can still benefit from a battery. You can charge your battery from the national grid overnight when electricity is at its cheapest and discharge your stored electricity during the day or in the evening when electricity is most expensive.  So, reducing your energy bill.
