What are Battery Energy Storage Systems (BESS)?

Battery energy storage systems (BESS) capture surplus energy from both traditional and renewable sources. These assets ensure grid stability during periods of low demand and enable efficient storage of energy for optimal usage.

Large-scale battery storage is becoming increasingly important for a wide range of industries, enhancing energy efficiency and power distribution. Custom-designed BESS reduces power consumption, improves the sustainability of electrical networks, and plays a crucial role in achieving the UK’s 2050 net-zero targets and stabilising the power grid.
