E.ON has completed the installation and grid connection of its 10MW battery at the Blackburn Meadows biomass plant near Sheffield.

This new energy storage project t will help keep power supplies stable and support the range of power generation sources feeding into the UK’s national grid, the company said.

The battery is housed in four 40ft long shipping containers. It has the same power as roughly 100 family cars and holds the same amount of energy as 500,000 mobile phone batteries.

The Blackburn Meadows battery was successful in National Grid’s Enhanced Frequency Response (EFR) tender to deliver technologies capable of responding in less than one second at times of either an over- or under-supply of energy to the grid.

Power supply and demand on the UK grid have to be matched closely in real-time to maintain a safe frequency so household electrical appliances function properly.

Balancing the grid is becoming more challenging because the growing range of renewable generation sources make the electricity system less stable and more prone to changes in frequency.

Battery systems work by immediately discharging power to the network when the frequency falls – either when supply drops or when demand increases – bringing the frequency back up. The battery is also available to take power off the network if supply is greater than demand.

As well as helping to make more efficient use of renewable energy sources, the batteries will also be able to provide extra power to the network at times of peak demand as part of the Capacity Market.

David Topping, Director of Business Heat and Power Solutions at E.ON, said: “Blackburn Meadows is a real example of the new smart energy world – a renewable energy plant providing electricity to the grid and sustainable and affordable heating and hot water to local businesses.

“Batteries at this scale allow us to make best use of all renewable energy sources by harnessing the energy and having it ready for use whenever it’s needed – increasing the share of renewable energy on the grid while at the same time providing a secure supply for our customers.”
