Battery storage technology has a key part to play in ensuring homes and businesses can be powered by green energy, even when the sun isn't shining or the wind has stopped blowing. For example, the UK has the largest installed capacity of offshore windin the world, but the ability to capture this energy and purposefully. Battery energy storage systems are considerably more advanced than the batteries you keep in your kitchen drawer or insert in your children's toys. A battery storage system can be charged by electricity generated from renewable energy, like wind and solar. Storage of renewable energy requires low-cost technologies that have long lives – charging and discharging thousands of times – are safe and can store enough energy cost effectively to.
National Grid has been making changes to try to use batteries more. However, Olly Frankland, an electricity storage specialist at Regen, said they had been “a little bit slower than they should have been”. “There is encouraging messaging and good direction of travel, but I think what we're asking for is a wider role for battery storage.”
Is National Grid speeding up battery energy storage connections?
Image: National Grid National Grid is speeding up the connection of about 10 GW of battery energy storage projects to the transmission network in England and Wales. The company, which runs Britain's energy systems, said that 19 projects will be offered new connection dates averaging four years earlier than their current agreement.
Ben Guest, managing director of the new energy division at Gresham House, said National Grid is underusing battery storage that is already incorporated in the system, although it is seen as a crucial part of efforts to cut carbon emissions.
What is a grid-scale battery energy storage system?
Grid-scale battery energy storage systems (BESS) enable us to use electricity more flexibly and decarbonise the energy system in a cost-effective way. [footnote 31] As the technology and innovation in battery design, manufacturing, transportation, and deployment evolves, so will the development of additional applications.
What is national grid doing to speed up and reform connections?
Work is part of ongoing collaborative industry efforts, together with Ofgem and government, to speed up and reform connections. National Grid is accelerating the connection of up to 20GW of clean energy projects to its electricity transmission and distribution networks in England and Wales as part of ongoing collaborative work across industry.
Does National Grid offer a transmission connection before network reinforcements?
Following detailed technical analysis by electricity transmission engineers, National Grid will now offer selected battery projects a transmission connection before network reinforcements are made, on the agreement that the ESO can adjust the battery's behaviour in certain operating conditions to reduce system impact.
