Always green, forever energy. Advanced battery storage to keep the world shining

Battery Energy Storage Systems (BESS) are electrical storage plants connected into the grid network. They enable us to store the surplus clean energy we generate when not in use and discharge it into the network when the power is most needed.
BESS also help us provide better grid stability, as we can manage magnitudes such as voltage and frequency imbalances when renewable generation dips up and down.

Benefits of energy storage systems

01

Power system stability

Energy is stored and dispersed into the electricity network over a period of hours to take save excess generation and supply to peak demand

02

Frequency response

Electricity is rapidly imported and exported to balance fluctuations, ensuring the network frequency stays stable at 50Hz

03

Towards decarbonization

Incorporating batteries into the grid ensures that clean energy is not limited by intermittency, making it more competitive and reliable. This allows us to advance towards the common goal of decarbonization
