A Commercial Energy Storage System (CESS) is a large-scale battery solution designed to store and manage energy for businesses, factories, solar farms, and industrial facilities. Unlike residential systems, commercial energy storage handles higher power demands, reduces electricity costs, and enhances grid stability.

Introducing Commercial Energy Storage in the UK

Commercial energy storage systems are units installed on-site at companies in the UK to give the business the opportunity to store and discharge energy when it makes sense to do so.

The system operates independently from the National Grid, offering a brilliant back-up or stand-alone energy solution to businesses in numerous sectors.

In most applications in the UK, commercial energy storage solutions are integrated with solar panels, to captilalise on the creation of renewable energy and to leverage the numerous benefits of the technology.

At AceOn, we work with businesses in different sectors to harness renewable energy through commercial battery energy storage systems, and serve at the forefront of the UK’s march towards net zero.

Find out more about how energy storage systems for businesses work and learn about whether they’re right for your business.

What is Commercial Energy Storage?

Commercial energy storage is a system that can be installed at a business to provide an alternative source of green energy. Rather than relying on the National Grid to power your business exclusively, you can draw green energy directly from your commercial energy storage system. It has the following elements:

● Charging: The system draws green energy from a renewable energy source like wind turbines or solar panels.

● Storing: The energy is then stored until it is needed, offering smart management of the energy resources available to your business.

● Discharging: When energy is required – perhaps during peak hours – the system discharges and converts the stored energy into electrical energy.

● Managing: A computer system manages the flow of electricity in the battery storage system, ensuring that you can optimise its use and save money.

Given the United Kingdom’s ambitious green targets, commercial energy storage is a great way for businesses to reduce their reliance on fossil fuels and achieve greater energy independence, as we explain below.

How do Commercial Battery Energy Storage Systems Work?

Commercial energy storage systems, sometimes known as commercial battery energy storage systems or renewable energy storage, is a green technology that offers businesses in the UK increased independence from the National Grid.

Most commercial-grade systems capture and store energy generated from renewable technologies, including solar, wind, and biomass.

The energy is stored in batteries. It can then be drawn upon when it is required, for instance, during peak periods of energy usage or during the night.

Some companies in the UK generate income through commercial energy storage systems, as they can serve as a “balancing mechanism” to the National Grid, providing energy to help power the UK.

The benefits of commercial energy storage

The benefits of commercial energy storage are numerous:

More sustainable

This technology gives businesses the opportunity to utilise and harvest clean solar energy at times that it’s beneficial to do so. It helps businesses become more sustainable and reduces reliance on fossil fuels. It also offers energy independence and means your business will not be solely reliant on the National Grid.

Peak shaving

Businesses throughout the UK use commercial energy storage at times of peak demand. Known as “peak shaving,” by switching to your battery storage during peak hours, you don’t have to pay peak energy costs, saving your business money on utility bills, which is highly attractive given the current cost of living crisis.

Load shifting

Like peak shaving, load shifting is a unique benefit of energy storage. It’s the practice of shifting your company’s energy consumption from one point in time to another to avoid peak energy prices.

Energy back up

Commercial energy storage systems provide a source of backup energy to your business. In case of a brown out or even a black out, you can draw on your reserves and keep your business running, no matter what’s happening with the National Grid.

The capabilities of commercial energy storage

The capabilities of commercial battery energy storage systems vary depending on its configuration. The storage of commercial-grade systems is given in kWh. Some businesses can make do with a system that has a capacity of up to 20 kWh, but others may need something upwards of 100 or even 200 kWh.

One of the best things about commercial energy storage systems is that they are flexible and dynamic. They can be tailored to meet the exact requirements of your business, and are suitable for businesses in practically all sectors, from transportation to engineering.

If a system is well maintained, we expect commercial energy storage systems to have a lifespan of between 10 and 20 years.

FAQs

Is commercial energy storage worth it?

Though some businesses question the price associated with installing commercial energy storage, the long-term cost saving benefits are difficult to ignore. Thanks to peak shaving and less reliance on the National Grid in general, these systems can save your business lots of money in the long run.

What are the benefits of commercial battery energy storage systems?

Businesses that turn to battery energy storage systems enjoy increased independence from the grid, more sustainability, and the ability to harness and leverage green energy. There are also long-term cost savings to benefit from.
