Battery energy storage is becoming essential to the UK’s transition to a low-carbon energy future. By storing surplus electricity from renewable sources like wind and solar PV farms, BESS enables the storage of surplus energy to be used when needed most (not just when it’s produced). These systems also play a key role in stabilising the grid and improving the overall reliability of the power supply.

In this article, we explore how the UK’s BESS market is evolving, covering policy changes, deployment trends and future projections. We also highlight the vital role of engineering consultancy in delivering safe, scalable and efficient battery storage solutions.
