Grid Applications


In general, for renewable technology generators* in excess of 16A per phase (3.66kW), the connection must comply with Engineering Recommendation G59/3, published by the Electricity Networks Association.

Customers, developers or installers who wish to connect renewable technology generators* within this category must provide a fully completed G59/3 application form plus all associated documentation.

Cellnexx Energy Limited will work with the DNO to consider the application and advise whether a connection to G59/3 is acceptable and detail any work, costs and the associated timescale.

For certain generation connections, particularly those which need to comply with ER G59/3, there may be a need for additional site specific requirements to be reflected in the connection agreement.

All customers connected to the National Grid Network must have an agreement to remain connected. A general set of these terms is available upon request.

For G59/3 applications there could be additional costs to take into consideration before grid authorisation is permitted. These additional costs may need to cover grid point of connection or even a grid upgrade. However, these costs will only be identified after the G59/3 application has been processed.

Cellnexx Energy has become proficient in delivering zero costs to customers and, in almost all cases, if there are costs we have been successful in reducing them by up to 40%.
