Ofgem is the regulator for Long Duration Electricity Storage and oversees implementation of a 'cap and floor' regime for LDES projects, proposed by the Department for Energy Security and Net Zero (DESNZ). The aim of this regime is to stimulate investment in Long Duration Electricity Storage projects.
For an electricity storage technology both the rated storage capacity (GW) and the rated volume (GWh) are important to define the storage ratio - the amount of time a technology can discharge for at full power. This, in turn, influences the application type each specific electricity storage technology can be used for.
Long Duration Electricity Storage (LDES) technologies contribute to decarbonising and making our energy system more resilient by storing electricity and releasing it when needed. LDES can also help reduce costs for consumers through reducing their bills and by avoiding the need for expensive electricity grid upgrades.
As we head towards a net zero system, electricity storage will play a vital role in helping manage supply and demand. There are various electricity storage technologies with different technical and commercial characteristics that can serve this purpose, with a wide range of outcomes for their future deployment.
Given optimal market signals, electricity should be stored at times of high renewable generation / low demand and delivered back when demand needs are higher and generation outputs are low. There are various electricity storage technologies which have different characteristics and play different roles in the system.
