Network Flexibility

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.

Flexibility Markets – Short Term Bidding

Our short-term bidding rounds are run to ensure we procure the flexibility volumes we need, but where previous long-term rounds did not fulfil all the requirements, Flexibility Service Providers (FSPs) declare their unavailability or where updated forecasts require more flexibility. Short-term bidding rounds are run a month ahead of need.

Flexibility Markets – Long Term Bidding

Our long-term bidding rounds typically involve flexibility requirements from our Distribution Network Options Assessment (DNOA) process that determines flexibility needs from our Extra High Voltage (EHV) network in the next three years. In addition, we include High Voltage/Low Voltage requirements at year ahead. This is normally flexibility needs for reinforcement deferral, or where our Control Rooms require flexibility for outage planning.

Flexibility Dispatch Report

The Flexibility Dispatch report is a weekly ahead flexible services utilisation report which provides a summary of the dispatch instruction for both SEPD and SHEPD licence areas.  The data identifies the area where the service products will be dispatched and how much capacity will be instructed from different flexibility providers. The Flexibility Dispatch report is intended to give our stakeholders an insight about the future usage of flexibility services and help them to better understand the potential opportunities for flexibility utilisation. The dataset also contains historical dispatch information dating back to 2023.
