Energy storage for your business


Commercial Battery Storage Service

Batteries are a key aspect in maximising the full potential of renewable energy. Large battery sites are being set up all over the UK to store renewable energy produced during peak times. When the weather gives us more sun or wind, a great amount of solar and wind energy is generated. This excess energy is stored in batteries for us to use at night or during cloudy days as part of our transition away from fossil fuels.

Why choose Flame Energy for your battery storage?

Our team of dedicated experts at Flame Energy can help your business store the excess energy it generates. We can also help you in the process of selling any unused energy back to the grid.

Why choose to store your excess energy in a battery?

Choosing a battery to store any excess energy you generate guarantees the security of your energy supply. At a time where energy supplies are at a premium, choosing to store energy gives you peace of mind. If your supply is sensitive to energy blackouts, storing your own energy is a great way to reduce the risk.

What is the payback period like for batteries?

Batteries don’t produce electricity so do not have a pay back period but will help power your business when it is no longer sunny.  Having battery storage means you will be able to store energy produced by your solar panels, and therefore don’t have to buy electricity from the National Grid.

How will batteries help my business save money?

If you have solar panels, battery storage can help save you money as you can store excess energy on sunny days, ready to use on overcast days or overnight.  This means that you will not have to buy as much, if any, electricity from the National Grid when your panels are not generating sufficient electricity.
