Battery developer Root-Power has submitted four storage projects totalling 300MW into Ofgem’s Long Duration Energy Storage (LDES) tender.
The projects, in West Yorkshire, North Yorkshire, Buckinghamshire and Lincolnshire, will utilise vanadium flow batteries to deliver a combined 2400MWh storage capacity.
Ofgem opened initial applications for the LDES cap and floor scheme in April 2025 as part of plans to expand the UK grid’s access to energy storage, with all projects requiring 25 years of capacity and power delivery.
LDES forms part of the Government’s Clean Power 2030 programme, with forecasts that an indicative capacity will be between 2.7GW and 7.7GW by 2035.
Neil Brooks, Managing Director at Root-Power said: “. Whether its two- to four-hour lithium-ion batteries or eight-hour vanadium flow batteries, Root-Power is committed to taking a leading role in delivering essential infrastructure for the future.”
We look forward to working with Ofgem, our partners and other stakeholders to make the LDES initiative a success and to continue our mission to support the UK’s transition to Net Zero.”
