G59/G99 Fast track applications
WPD offer a fast-track application process for connecting energy storage devices that meet certain defined criteria. If your energy storage scheme relates to a single phase connection where there is either:
- an existing PV installation (or other DG type) that conforms with ERG83 requirements and you wish to install a battery storage device via a separate ERG83 type tested inverter; or
- you wish to install both a new PV (or other DG type) scheme and battery storage device via two separate ERG83 type tested inverters
then subject to meeting further eligibility requirements, you may utilise the fast-track process.
|Are you applying to connect at a single property?|
|Is the combined installed capacity of your generation and battery storage devices less than 32A per phase?|
|Is the individual capacity of each of your generation and battery storage devices less then 16A per phase?|
|Will your export capacity be limited to a maximum of 16A per phase via an export limiting device that is compliant with ERG100?|
|Will both your generation and battery storage devices be connected via ERG83 type tested invertors?|
|Will both your generation and battery storage devices be prevented from operating in island mode, i.e. when there is no mains supply?|
If you answer ‘No’ to any of the above questions you will need to apply under the conventional ERG59 route.
If you answer ‘Yes’ to all of the above questions, you may proceed with a fast-track application.
What happens next?
Once you are confident that you wish to proceed, please complete and submit an application form. For following flowchart outlines the steps required for a G59 Fast Track application:
