Commercial Energy Storage

The UK has undergone a rapid transition toward renewable energy. In the third quarter of 2019, the UK’s wind farms, solar panels, biomass, and hydro plants produced more energy than that produced by coal, oil and gas-fired power stations. The biggest challenge facing renewable energy producers is that, unless the electricity generated by biomass, water, wind, and solar power systems isn’t fed directly into the grid or used immediately, it’s lost.

Capturing this excess energy so it’s ready to use is a fundamental challenge that requires energy storage innovation. Battery energy storage systems are offering those producing renewable energy or those wanted to efficiently store energy, the opportunity to capture this electricity in a network of batteries.

A grid of high-density Lithium-Ion batteries linked together can safely store electrical energy with a high level of efficiency – meaning the majority of all energy produced is safely stored. They can also be scaled up, with additional capacity added when it’s required. This development offers incredible benefits to producers, people, and the planet.

Installing large scale storage on the grid network better enables the balancing of supply and demand and assists in providing technical services such as frequency response and voltage optimisation.

Time of use benefits

Battery energy storage systems aren’t just an attractive option to renewable producers; they’re also increasingly being adopted by the forward-thinking businesses too. Battery storage systems can be used to store energy purchased at off-peak times. It can be switched on to distribute energy when tariffs are at their highest, cutting energy bills. Avoiding ‘red tariffs’ – when prices are at their highest – can save businesses of all sizes significant amounts.

Battery storage systems can also be configured to work as an uninterruptible power supply, providing a welcome insurance policy for businesses. In the event of a power outage, disruption or grid drop out, battery energy storage systems can step in. While there is a limit to the power a battery storage system can contain, it can deliver the power needed to safely back-up and shut down critical systems.

Peak shaving

Peak shaving involves proactively managing overall demand to eliminate short-term demand spikes, which set a higher peak. This process lowers and smooths out peak loads, which reduces the overall cost of demand charges. We believe solar + battery energy storage is the best way to peak shave.

Commercial Battery storage


The most well-known and widely used in consumer electronics, lithium-ion batteries have high energy density, low standby losses and tolerance to cycling. There are many different applications, however the most popular at the moment is their application in Electric Vehicles. They are very flexible in their discharge time, which can be realised from seconds to weeks. Although prices are still considered to be relatively high, they have started to come down in price, and it is projected that this the trend will continue in future years. A relatively new technology but likely to be widely deployed in the short term.

Can I Have a battery system without solar PV

Business owners you do not require a solar PV plant on the roof for you to employ battery storage technology In your building in an effort to achieve some noticeable bill savings by using the time of use method noted above.

Funding for energy storage

There are many business owners who value the flexibility that grid connected battery storage systems offer & may want to acquire this asset without employing upfront capital costs. Synergy Power has ongoing relationships with various battery funders who provide solutions for businesses prepared to enter contracts for the provision of battery storage services.
