Flexibility Services

To meet evolving customer needs, we are developing smarter, more flexible network solutions to help mitigate the need for traditional reinforcement and reduce costs for our customers. This is cheaper for our customers as it enables us to delay expensive reinforcement work for as long as possible.

Resources connected to our networks could provide both additional capacity and additional generation to assist in key areas that have specific challenges during periods of network constraint.

We are exploring markets for flexibility with new and existing customers who are able and willing to control how much they generate or who can control their demand.


About Flexibility

Flexibility Services Overview



Flexibility services is where a Distribution Network Operator (DNO), like us, pays a third party to operate assets in a way that’s beneficial to our network. Those third parties will be owners of generation assets or low carbon technologies (LCTs) such as wind turbines, battery storage, solar or electric vehicles, and we may ask them to “turn down” or up depending on the needs of our network. In other words, we might ask them to lower the power consumption of their assets for an agreed period to allow us to free up that capacity for use elsewhere, or we might ask them to use more power in areas where we have excess generation.

As the needs of our customers and communities are constantly changing, the requirements of our electricity network are too. The increased uptake of LCTs does often result in constraints on the network during periods of high demand. However, new technologies and connections can often lead to excess generation in other areas too. Flexibility therefore provides an agile, smart means of balancing our network to solve both of those challenges.

Flexibility Providers

We will look to procure flexibility services through competitive tenders where possible and the responses from the flexibility providers will be used to:

  • Identify the availability of flexibility resources in specific areas where flexibility could benefit the network.
  • Understand the capabilities and restrictions of these resources.
  • Evaluate the viability of using flexibility to meet network requirements.
