July 22, 2021: Finnish technology firm Wärtsilä is to expand on its two Pivot Power battery projects in the UK with another 100MW/200MWh of energy storage, the technology firm announced on July 19.

The storage will consist of two systems — which the firms are calling ‘superhubs’ — in the West Midlands, in central England, and construction will begin in the last quarter of 2021.

They will be big enough to power 200,000 homes for two hours, the firms claim.

“At both sites the battery storage systems will share their connection to the high-voltage electricity transmission network with a high-volume power connection, which will deliver large amounts of power for rapid EV charging to strategic locations in the local area, from public charging hubs to bus depots and commercial fleets,” says Pivot Power.

Where Wärtsilä will provide the energy storage technology, UK firm Pivot Power will operate the system in a similar model to an ongoing Oxford project which uses a vanadium battery as well as lithium-ion.

The Midlands project is an expansion of the Oxford ‘Energy Superhub’ system, which was intended as a demonstrator project for the hybrid battery model, says the firm.

“It was part funded by the government and will run until 2023, with the aim of testing and evaluating new technologies and businesses models. The results of this project will help to inform future developments. In the meantime, Pivot Power’s focus is on deploying lithium-ion systems, which are delivering reliable, cost-effective energy storage globally to accelerate a net zero future.”

Pivot Power’s ‘superhubs’ are all placed alongside National Grid substations, ‘and have been selected for proximity to major road networks and urban populations’, says Pivot Power.
