Which Distributed Generation Connection is right for your project?

From 6 April 2017, all 'Connection Offers' where the export capacity is ≥ 200kW will include progression milestone dates. This follows on from the Energy Networks Association consultation 'Fair and Effective Management of DNO Connection Queues: Progression Milestones - April 2016' shared with our DG mailing list subscribers 29 April 2016 and the publication of the 'Best Practice guide - 3 November 2016' shared with our DG mailing list subscribers 11 November 2016.

You can view the consultation documents here and the Best Practice guide here

Single connections rated up to 16 amps per phase are designed to operate in parallel with a public low voltage distribution network. In accordance with ESQCR and HSE Certificate of Exemption (2008) the installer is required to advise the DNO of the intention to use the SSEG (Small Scale Embedded Generation) in parallel with the network no later than 28 days (inclusive of the day of commissioning), after commissioning the SSEG.

For further information please download:   

Energy Networks Association - A Guide for connecting Generation to the Distribution Network in a Single Premises that falls under G83/2 (Version June 2014) [pdf]

You must also supply a final copy of the circuit diagram and SSEG Test Report (protection settings if applicable) in line with the Energy Networks Association document ER G83/2. Both forms must be completed and submitted within 28 days of commissioning to: G83notification@ukpowernetworks.co.uk or Fax: 01293 577760

When connecting more than one unit, in a single installation, or in a close geographic region, under a planned programme of work.

Energy Networks Association - A Guide for connecting Generation to the Distribution Network in Multiple Premises that falls under G83/2 (Version June 2014) [pdf]

Anyone wishing to install this type of generation must apply to UK Power Networks, prior to installation. This is an obligation under the Electricity, Safety, Quality and Continuity Regulations 2002.

Please send completed form to: connections.gateway@ukpowernetworks.co.uk or Fax: 08456 500 248

 

 

Large Generation or G59 Generation connections refer to all non G83 generation connections (above 16 amps per phase).

Anyone wishing to apply for this type of generation connection must complete the ENA Generator Application Form. Please send completed form to: connections.gateway@ukpowernetworks.co.uk
 
 
 
 
 Please ensure you include the following with your ENA Generator Application Form:
  • G59 checklist
  • A Letter of Authority from the landowner/occupier
  • Site plan at a scale of at least 1:500 including the six digit X, Y OS grid co-ordinates showing identifiable landmarks, site boundary and proposed location of incoming connection point
  • A single line diagram (SLD) of the proposed installation showing the location of the protection systems, the associated automatic disconnecting devices, the interface with UK Power Networks and the customers network including loads, generators, transformers, circuit breakers and cables
  • Fault level data - this is the fault contribution from your installation/equipment into UK Power Networks network (not the rating of your equipment) at your preferred connection voltage
  • Details of harmonics, flicker and any other disturbing equipment you plan to connect
  • For wind turbine developments, a detailed dimension drawing of the tower and turbine assembly
  • If customer has an existing supply and wishes to install a generator, a technical appraisal is required
  • If you are applying for Storage please complete and submit the ENA Energy Storage System - Further Information Request form with your ENA application
 
Feasibility study
A feasibility study can assess connection opportunities for individual developments or a comparison of different developments. It can include a technical consultation, assistance for compliant design and/or multiple option surveys. Please note that there is a charge for this study.

 

Establish the nearest point for your connection
