This marks the first major government-backed effort in over four decades to scale up long-duration energy storage infrastructure in the UK. Application window now open: Developers must submit intent to apply by 22 April 2025, with final applications due by 9 June 2025. . Long Duration Electricity Storage (LDES) facilities provide vital back-up for the renewable power system – working like giant batteries that store electricity created by wind and solar farms, then release it to the grid when needed. . ications which have been quoted in this report. The information and advice provided by the Department of Business Energy & Industrial Strategy (BEIS), the Committee on Climate Change (CCC) and National Grid ESO, among others, has been invaluable in carrying out this work and deriving the results of. . The Long Duration Electricity Storage (LDES) Technical Decision Document (TDD) was published on 11 March 2025 by Ofgem and the Department for Energy Security and Net Zero (DESNZ). AG's Energy team looks at the detail. .
Water - based sprinkler systems are effective for protecting areas where the risk of ordinary combustible fires exists, such as storage areas in a substation where wooden pallets or paper records are stored. These systems are activated by heat sensors. However, like any electrical infrastructure, energy storage systems come with their own set of risks, particularly fire hazards. Experimental and simulation analyses have revealed patterns in heat release rates, flame heights, flame temperatures, flame resistance, and. . For an electrical substation, the fire protection system must ensure the safety of critical equipment, minimize downtime, and protect personnel while addressing the unique risks posed by electrical equipment. Transformer failures, cable vault overheating, and arcing incidents expose substations to heat and flame hazards capable of cascading across equipment.
