With the significant change to planning legislation in the UK in July, the door to large-scale battery storage is now open. Already, this has allowed the nation’s biggest ever site to be announced, with InterGen set to build a 320MW asset in Essex, and an increasing number of storage projects to have been announced by major players like Gore Street and Gresham House. Speaking to Solar Power Portal recently, Peter Kavanagh, CEO of battery energy storage and solar company Harmony Energy, said the changes to legislation will “definitely” lead to more 50MW-plus scale projects. “We definitely see that the main investor appetite is for 50MW and above projects, because I think National Grid wants to see more of those assets on the larger scale as well. I think it’s an exciting development, including for Harmony and we will be looking at one or two of the larger scale sites. “But I don’t think our strategy will change so we suddenly pursue, for example, 200MW sites in isolation, because we still think you need some of the smaller sites to make the system more efficient.” As of July, there was already more than 13.5GW of battery storage projects in the pipeline, according to Solar Media’s UK Battery Storage Project Database Report. Of this, 1.3GW is ready to build, 5.7GW has planning permission and a further 6.5GW is proposed.
