DNO Managed Connections Progress

The UK Distribution Network Operators (DNOs) have recently published their latest work plans for the Incentive on Connection Engagement (ICE). We have listed below the current progress on managed connections that each DNO has made, outlined roll-out plans if known, and included links to the latest ICE work plans. 

This is designed to help generation developers to understand what connections are available to them. If you would like to discuss managed connections, please contact us.

UPDATE

The DNOs have released an October Update to their ICE Plans, you can read a summary of the new documents in our news article.

Timed: Generation curtailed within specific times

  • Sub-1 MVA
  • Modelled Seasonal Capacity Variations
  • Localised control only
  • No comms
  • Non-optimised

Soft intertrip: Releases pre fault capacity with trip facility

  • 11kV and 33kV
  • Real-time monitored values
  • Small clusters on generation or simple pinch points
  • Existing monitoring with localised control

Active Network Management: Fully optimises capacity based on all constraints

  • Management of generation using LIFO principles
  • Real-time granular control of output
  • Requires new Active Network Management control and monitoring systems

WPD also offer export limiting connections.

Alternative Connection Type Areas
Export Limiting Entire Network
Timed Entire Network
Soft-Intertrip All non-complex networks not due to be opened for ANM within two years
Active Network Management (ANM) See ANM roll-out plan

UK Power Networks is rolling out Flexible Distributed Generation connections:

  • In a phased manner
  • To defined geographical zones on the network
  • Where there are constraints in network capacity and high customer demand.

The FDG connection includes an automatic control (active network management) system and communications which interfaces with the generator’s control system and provides granular curtailment and fail safe services. Information available here » 

Region Zone  Status 
 EPN Peterborough - March (Original FPP Zone)   Closed 
 EPN Norwich  Closed 
 SPN Lewes - Eastbourne  Delayed - Awaiting completion of technical studies 
 SPN Kemsley - Sittingbourne  Closed 
 EPN Walpole East - Kings Lynn (Extension of original FPP zone) Closed 
 SPN South coast - Transmission and Distribution Interface 2.0   EOI - 12 May - 5pm 27 May 2016 
 EPN Maldon - Fleethall  Appliction window 20 June - 5pm 1 July 2016

Quicker and more flexible connection arrangements currently include:

  • Non-Firm connections; overload intertrip scheme allowing for the removal of a generator in the event of pre-determined network thermal limit being reached. Applicable to 33kV & 11kV connections.
  • Export Restricted connections; using export management devices, commissioned against a pre-determined export limit and managed by customer's export limiting device.
  • Active Network Management (ANM); provision of dynamic export limits derived from network owned active management equipment.

NPG will work with customers to produce a managed connection that meets their needs. Typical managed schemes would address single constraints at a single point on the network, constraints at certain times of year, week or day, or constraints which arise under outage conditions.

Generation with Export Limitation schemes are considered on a case by case basis. It is expected this will become more widespread when an ENA Engineering Recommendation for Export Limiting Schemes is produced, probably in the next 12 months.

Operate normally radial circuits in meshed configuration to increase capacity for both demand and generation.
