We design, deliver, and operate Battery Energy Storage Systems (BESS) that serve a greener, sustainable, and more flexible National Grid.


With 25 years’ experience of delivering large-scale electrical infrastructure across the UK, we have developed our integrated utility connections and energy management solution to become a market leader in the construction and operation of grid-scale battery storage.

Our specialist team design, supply, install, operate, maintain, and optimise large battery sites working alongside a wide range of partners and stakeholders – from investors and landowners to renewable energy developers and local communities.

With inaugural projects in Burwell, Cambridgeshire (50MW) and Barnsley, Yorkshire (40MW) operational from early 2022, SMS has a project pipeline that is set to establish 470MW of energy storage by 2025.

What is grid-scale battery storage?

Battery storage is an essential technology for overcoming the energy system’s biggest modern challenge: the transition to clean energy.

As renewables are intermittent, batteries connected to the National Grid are needed to store clean electricity whenever it is generated. In this way, green energy can be supplied and consumed on demand by the UK population no matter what time of day it is, or how the weather is.

In addition to helping phase out fossil fuels and reduce carbon emissions, batteries also play an increasingly vital role in stabilising, balancing, and protecting the grid, adding a much much-needed layer of flexibility as the UK moves to electric vehicles (EVs) and heating systems in coming years.

Best-in-class battery solution
Our commitment to sustainability 

At all of our battery sites and across our entire business, SMS is committed to leaving a positive environmental and social impact. This includes:

• Implementing a range of on-site biodiversity improvements 
• Protecting habitats around the perimeter of the site with fencing
• Working closely and engaging regularly with the local community 
• Installing a low-carbon technology critical for carbon reduction
