‘Next generation utility’ wins contract for UK’s biggest battery

Demand response software start-up Limejump has won the contract to manage the energy storage facility dubbed ‘Britain’s biggest battery’ by project developer UK Power Networks.

Located in Leighton Buzzard, the 6 MW Network Storage Facility has been developed to help support the growing amount of intermittent renewable power sources on the grid.
Business Green reports that the facility has a storage capacity of 6 MW and 10M Wh, which is enough to import or export continually 6 MW of power for an hour and a half. The site’s primary function is to support the local network during winter peak periods of demand.

UK Power Networks said it had developed and trialled the large standalone battery in order to “aid the transition to a more flexible electricity system”.

Following the successful trial of the à‚£19m batteryà‚ last year, the company sought to outsource the commercial operations of the facility in order to comply with its legal obligations as a distributed network operator.

And last week the management contract was awarded to self-described next generation utility, Limejump, which said it would use the battery’s energy outside the winter period to help balance the grid via demand response services.

When fluctuations from balancing the grid with renewable power generation occur, Limejump said it would be able to action quick charges and discharges with the use of batteries.

Erik Nygard, chief executive of Limejump, said, “Batteries are enjoying significant growth; they are playing an ever-more important role in the energy market, as they support the use of renewables and protect the grid against the continued removal of coal power stations. They are an essential part of renewable energy generation, as they can quickly respond to the fluctuations on the grid imbalance caused through intermittent solar and wind power.”

Limejump operates the largest portfolio of energy storage projects in the UK andà‚ last monthà‚ said it was aiming to bring 185 MW of storage capacity online by the end of this year in partnership with renewable energy developer Anesco.
