Battery Energy Storage System (BESS) Developer Root-Power today (June 10) announced that the plans has submitted for four energy storage projects in the tender (LDES) from OFGEM.
The four LDEs projects submitted by Root-Power for the Cap and Floor Scheme have a combined 2.4GWH of storage capacity and, if approved, will be built in West Yorkshire, North Yorkshire, Buckinghamshire and Lincolnshire. All four projects will use Vanadium Flow Battery Systems, a technology that is currently relatively unusual in the British Bess sector.
Prior to today’s announcement, Root-Power was almost exclusively involved in delivering 2-hour and 4-hour lithium-ion battery projects, in contrast to the 8-hour durining batteries of the expensive vanadium stream used for the proposed projects.
OFEM’s Cap and Floor Investment Support Scheme for LDES projects launched in April of this year, after an extensive cooperation development process between the Department for Energy Security and Net Zero (Desnz), the National Energy System Operator (NESO) and OFGEM.
The scheme aims to encourage the development of more LDEs projects by balancing the trust of investors and public value for money by determining minimum and maximum income that can be achieved with LDES projects. The first application window for the schedule was closed yesterday (June 9, 2025). To date, most projects that show interest in the schedule, Poes projects of Hydro Energy Storage (Phes) have been pumped instead of storage proposals on battery energy.
Root-Power was launched in July last year as a specialized BESS loopers of the YLEM group, and has since made more than 40 projects progressed by a phase of development. At the end of last month, the developer announced that it had broken the ground on the Dounreay Bess, a 34 MW/68MWH Bess development in a remote coastal area in the Scottish Highlands; The location was specifically chosen to support the “big overhaul” that expects the development of wind energy in the coming years.
Neil Brooks, director of Root-Power, said that the company was dedicated to lead the future of energy storage in the UK. He added: “Our team has been developing these projects carefully for a while and it is fantastic to see the highlight of that work while these projects join our wider portfolio of battery energy storage systems.”
