DG Connection Guides

There are four separate Distributed Generation Connection Guides, each with a corresponding ‘Summary’ guide. The purpose of the summary guides is to act as a quick check, providing only the most useful information in a condensed format. Each full guide has a flowchart that guides you to the most relevant Connection Guide for the Distributed Generation you are planning to install.

The Guides are intended to help you, as an owner or developer of Distributed Generation, to connect your generating plant to one of the UK's electricity distribution networks. A record of all revisions can be found at the rear of each guide. Please note that these are only guides to ER G98 and G99, not the actual technical engineering documents. Both engineering documents can be freely downloaded from the Distribution Code website.
