FAQs
Got a question? You’ve come to the right place.
How much money will my business save?
Battery storage can cut your annual energy costs by 5-15% and generate income from otherwise underused assets.
How much does a battery cost?
This will vary depending on the system design, but an indicative guide is around £500,000 per MWh of installed capacity. Become Energy offer third party financing which delivers attractive financial returns without any capital deployment or associated risk.
What type of battery will you install?
We are technology agnostic which allows us to design and implement the most optimal system for you. Typically, the battery technology will be lithium ion, which provides the commercial availability and operational suitability we look for in behind-the-meter solutions.
How big will the battery be?
The system sizing is based on the energy requirement to manage network charges, participate in frequency response, and battery capacity degradation over 10 years. As an indication, a site with an annual electricity spend of £500,000, could expect a battery storage system to measure approximately 6m (l) x3.5m (w) x 2.5m (d) – roughly equivalent to a small shipping container.
Where will it go?
We will work with you to identify the most suitable location for your battery storage system. Considerations will include convenience for your business, the system size and footprint, proximity to the internal HV (High Voltage) distribution circuit and access for installation and maintenance visits.
How long will it take to install?
If you choose to work with us, our aim is to have a battery storage system installed and operational within six months.
How long will the battery last?
We design battery storage systems to be commercially and technically viable for a minimum of 10 years. This is calculated based on the number of discharge cycles. Subject to suitable maintenance, the systems may extend beyond this in a de-rated capacity or with a battery upgrade.
What happens if something goes wrong with the battery?
Become Energy will manage your battery storage system throughout its life and conduct regular maintenance visits. Each battery is equipped with a Battery Management System which enables us to monitor its performance remotely and respond to any issues. Batteries are supplied with a manufacturer backed 10 year warranty.
Are battery storage systems safe?
Yes. All of the battery storage system vendors that Become Energy works with design and build their battery storage systems to international standards, importantly IEC 62133 Standard for Battery Safety Testing. In addition, the tier 1 vendors that we use undertake independent testing, including destructive and thermal tests. We are happy to obtain examples of these documents from our vendors as required.
What happens to the battery at the end of its life?
Become Energy’s aim is to redeploy used batteries to tackle energy access and fuel poverty challenges, in the UK and internationally. Where this is not possible, we will recycle the system in the most appropriate and ecologically sound manner.
