Recommendation 54

There are many actors with a role in delivering long-duration storage, from the Department of Energy Security and Net Zero, Ofgem, the proposed Future System Operator, energy companies, the electricity transmission network owners and so on. In particular, the FSO has a potentially difficult role in coordinating and balancing supply and demand on a grid that is larger, more complex, decentralised and variable than before. There is a need for an overall “guiding mind” with the authority to take decisions and coordinate actions.
