Our G99 application process follows 5 simple steps:
01
Initial Assessment – We start by reviewing your project details and grid requirements to find the best application route for your project.
02
Application Preparation – Our team will then compile all necessary technical data and submits the G99 application to the Distribution Network Operator (DNO) on your behalf.
03
DNO Liaison – We manage all communication with the DNO, respond to queries and progress the application through to approval.
04
Certification – Once approved, we secure the relevant G99 and, where applicable, G100 compliance documentation.
05
Handover & Advice – We provide a clear handover pack and practical guidance to help you remain compliant throughout the lifetime of your system.
A G99 certificate confirms that generation or energy storage equipment complies with Engineering Recommendation G99, which governs how systems connect to the electricity distribution network.
A G100 certificate confirms compliance with engineering Recommendation G100, which applies to export limitation schemes designed to prevent excessive power export and protect the local electricity network.
A G99 application typically takes 8–12 weeks, depending on the Distribution Network Operator (DNO), the size of the system, and the complexity of the project.
Yes, any generation or battery storage system connecting to the grid requires G99 compliance.
