About BESS

Battery Energy Storage systems (BESS) store and release electricity, helping balance supply and demand on the grid. They capture excess energy from renewable sources like solar and wind, storing it for use during peak times or when production drops. BESS improves grid stability, enhances energy efficiency, and supports the shift to cleaner energy sources.

What are Battery Energy Storage Systems?

Battery Energy Storage Systems (BESS) are technologies that enable energy from renewables, such as wind and solar, to be stored and released when the power is needed most.

This is vital to speeding up the replacement of fossil fuels with renewables across the UK’s energy network. As we push towards net zero, these systems will play a key role between green power supplies and responding to electricity demand.

  • Grid Balance:

    As supply and demand fluctuate throughout a typical day, the national grid needs to balance this variation second-by-second to ensure that electricity is supplied reliably and securely around the UK. Managing these peaks and troughs becomes even more challenging for the grid when the target is to reach net zero.

  • Energy Storage:

    Battery Energy Storage Systems help to remove the strain on the grid by storing surplus renewable energy when production is high or demand is low, and feeding it back into the grid exactly when required. This renewable back up power also prevents the risks of blackouts and disruptions.

  • Reliable Supply:

    BESS is instrumental in improving the reliability and flexibility of the grid. It ensures a stable and secure supply of power, particularly in the power intensive industrial sectors where BESS is becoming the leading cost effective production.

Soaring demand, unprecedented growth

Projections from the national grid’s ‘Future Energy Scenarios’ report, estimate that by 2050, the UK could surpass 50GW in energy storage, reinforcing the transformative potential of BESS in the UK energy sector.

On a global scale, it is also estimated that the deployment of energy storage will continue to triple every year. This could result in around 1100GW of stored capacity in 20 years time, demonstrating the huge appetite among landowners, developers and investors to enter battery storage’s rapidly growing market.
