Flexibility allows us to adjust power generation or consumption in specific areas to prevent the network being overloaded.

Managing the flow of electricity maximises network capacity, supports our infrastructure development plan and accelerates the transition to Net Zero.

We procure Flexibility Services from various energy assets such as generators, storage systems, and aggregated consumer energy.

We regularly announce new areas facing capacity constraints where we procure Flexibility Services to manage the network.
