Banks Renewables to invest £700k in wind farm site

Yorkshire-based independent renewable energy firm Banks Renewables is planning to invest £700,000 in an innovative energy storage system near Barnsley.

The company aims to install a 19m x 3m lithium-ion battery alongside the control building for the Hazlehead wind farm, which sits to the west of Barnsley between the villages of Crow Edge and Carlecotes.

The new system, which is roughly the size of a shipping container, would be able to store some of the energy being produced by the three-turbine wind farm and also capture it from the wider National Grid before releasing it at times of high demand.

And the scheme has already won the support of the Hazlehead wind farm’s community liaison committee.

The battery technology allows for a greater degree of resilience and flexibility to be introduced to the power network. It can capture cheap electricity produced at times of low demand or when wind or solar generation is abundant and hold it until it is needed, thus helping to avoid price ‘spikes’ when demand is high.

The Hazlehead battery would have a peak capacity of 1,000 kilowatts and a duration of 1,500 kilowatt hours, which is enough to fully charge over 35 electric cars

It would be positioned behind the site’s existing sub-station which is screened by mature trees, thus ensuring it has no visual impact on the surrounding area.

The Hazlehead Wind Farm generates almost 18,000MW of green electricity every year, which is enough to meet the annual energy requirements of more than 4,500 homes, and by doing so, displaces over 6,200 tonnes of carbon dioxide from the electricity supply network per annum.

It’s the first time that Banks Renewables, which is part of family-owned North East property and energy business The Banks Group, has looked to invest in co-locating energy generation and storage facilities.

If it gets the go-ahead, Banks will be aiming to have the new system in place and operational by the autumn, and it is also looking now examining whether similar projects might be undertaken at its other onshore wind farms around northern England and Scotland.

Mark Rowcroft, technical manager at The Banks Group, says: “The capacity within the connection to the electricity network that we already have at the Hazlehead Wind Farm provides an opportunity to co-locate electricity storage with generation and maximises the value of that infrastructure while reducing operational costs and electricity transmission losses.

“Energy storage systems such as this bring resilience and flexibility to the power network, allowing more renewable generation onto the National Grid in line with our Net Zero 2050 ambitions and ultimately leads to reduced costs to the consumer.

“The Hazlehead wind farm already generates enough clean green electricity to meet the annual energy needs of thousands of homes, as well as creating substantial revenues for its related community benefits fund, and this project will enable us to make further energy advances from this site.

“We hope the members of Barnsley Metropolitan Borough Council’s planning committee will see the merits of this innovative scheme and that we will be soon able to get on with the work required to bring it online later this year.”
