National Grid connects the UK’s largest BESS

National Grid has connected the UK’s largest battery energy storage system (BESS) to its transmission network at Tilbury substation in Essex.

The 300MW Thurrock Storage project, developed by Statera Energy, is now energised and supplying flexible electricity to the network across London and the South East.

With a total capacity of 600MWh, the facility can power up to 680,000 homes.

It will help balance supply and demand by absorbing surplus renewable energy and discharging it instantaneously when needed.

Tilbury substation previously served the coal-fired Tilbury A and B power stations before their demolition.

Powering the energy transition

To accommodate Thurrock Storage, National Grid reinforced the site with new protection and control systems, ensuring the network can safely carry the battery’s additional load. The connection marks a symbolic transition from coal to clean energy at the site.

John Twomey, Director of Customer and Network Development at National Grid Electricity Transmission, said:

• “Battery storage plays a vital role in Britain’s clean energy transition. Connecting Thurrock Storage, the UK’s biggest battery, to our transmission network marks a significant step on that journey.
• “Our Tilbury substation once served a coal plant, and with battery connections like this, it’s today helping to power a more sustainable future for the region and the country.”

Tom Vernon, Statera Energy CEO and founder, added:

• “We are delighted that Thurrock Storage is now energised, following its successful connection to the grid by National Grid Electricity Transmission.
• “Increasing BESS capacity is essential for supporting the grid when renewable generation, such as solar and wind, is low or changes quickly. It ensures that energy can be stored efficiently and returned to the grid whenever it’s needed.”

Work is also continuing at Tilbury substation to connect Statera’s 450MW Thurrock Flexible Generation facility, which is set to further support regional energy needs.

The milestone follows the July energisation of the 373MW Cleve Hill Solar Park in Kent, which is the UK’s largest solar plant, connected to the adjacent Cleve Hill substation.
