DNO Liaison

Our dedicated team has a well established relation with UK DNOs and other utilities across the world and has in depth technical and commercial expertise of power systems and distributed generation connections.

Connection Feasibility

Whether you’re looking for a new development or you have an old plant and would like to add renewable generation, BGS is here to identify the best solution for you.

BGS will carry out an initial assessment of your site, any existing connection agreements, demand/ generation technical data and will develop a grid connection approach strategy. We will organise connection surgeries with the DNO and conduct a technical discussion with their network engineers in order to extract the key grid information and identify potential risks and delays. BGS will produce a full report showing both a light summary of the connection options and a more in depth discussion of the technical and commercial implications of each grid connection options identified.

G99 Application

The G99 application is the first milestone of the generation project where preliminary technical data of the proposed project must be submitted to the DNO. BGS will ensure that the correct data will be submitted and will liaise with the DNO should they have any special requirements. The application process usually includes:

  • A G99 application form where the site data and fault level contribution must be specified
  • Site single line diagram including protection arrangement
  • Export Limitation Scheme design (if applicable)
  • Any further information that the DNO is entitled to request

Connection Offer Due Diligence

  • The connection offer due diligence will assess the DNO/TSO connection offer and it will flag if the best connection solutions were given by looking at both the technical and financial aspects of the offer.
  • Recommendations will be made on the alternative connection options and whether a different generation capacity is more viable.
  • The study will also assess the use of system charges, grid connection costs, statement of works costs and timescales.
