Flexible Networks & SPEN

To meet our 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.

We recognise that resources connected to our networks could provide services to assist in key areas that have specific challenges during periods of network constraint.

So 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.


Benefits

Flexibility will:

  • Reduce the need in some areas for costly, traditional reinforcement.
  • Allow consumers to capitalise on the opportunities arising from a transition to a smarter grid and participate in the low carbon future.
  • Assist Distribution Network Operators (DNOs) to transition to Distribution System Operators (DSOs) allowing us to plan and operate our networks more dynamically to meet changing customer needs.

Flexibility Services

We will look to procure Flexibility Services through competitive tenders where possible.

Responses from 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.

Locations

Ten areas with a potential need for flexibility services were identified and published on the Picloflex platform.

  • Ringway
  • North Shropshire
  • Newtown/Welshpool
  • Crewe
  • Carrington/Fiddlers Ferry

SP DISTRIBUTION

After a successful pre-qualification period, with 80% of registered assets passing the prequalification stage, we were able to take eight of the ten locations to competitive tender.  For the remaining two locations, an insufficient volume of providers met the pre-qualification criteria and we were therefore unable to progress to tender.

Whilst our call had also included requests for flexibility services in our SPD license area, unfortunately due to insufficient capacity being offered for the entire service period required, we are unable to place contracts for these locations at this time. We are also unable to place contracts for reactive power for the same reason.

The requirements tendered for plus the individual results for each of 10 locations are now included in the document below:
