G83/2

cheers for the plaudits ted, and thanks to everyone who wrote in to support our position on this and participated in the telephone conference call.

Good to know that Ofgem can actually be persuaded to make changes when approached in the right way with a logical argument.

I'm disappointed that the same can't be said for any of the organisations that we pay to represent us on issues such as this, none of whom seem to have either made a representation on this matter themselves, or alerted their membership to the issue.

It's not a perfect solution, but seems a reasonable compromise in the circumstances.

I had a meeting with Northern Power Grid yesterday, and it seems they're not intending to enforce this other than if there is a problem on an individual transformer that can be traced directly to someone flouting these rules with multiple installs on the same transformer. They also seem very open to testing out some of the other ideas we've discussed, and we're now looking at setting up a solar installer specific meeting sometime in december to discuss processes and procedures.

They also are working on a postcode based user searchable database that will flag up any areas where the connection capacity has been reached, which was a suggestion someone made in the telephone conference that then got fed back to the DNO's by Ofgem, and led to Northern PowerGrid realising they actually held all the data to do this, and that it'd save them and us a lot of engineer time in carrying out basic checks.

NPG are also planning to launch a new connections portal for submission of G83 notifications, stage 2 and G59 applications, and to allow registered users to track the progress of these applications - launch date is targeted at December apparently.

I'm feeling a lot happier about this side of things now than I was in September.
 
The change is to the way 'Close Geographic Region' (CGR) works and is to do with pre-notification.

If you have installed a SSEG on the same LV feeder circuit within the previous 28 days or have plans to within the next 28 days then you must get approval from the DNO before installing the system. If you do not know or cannot find out from the DNO if you are installing a SSEG on the same LV feeder circuit then you will require prior approval if the systems are in the same Post Code (AB1 2xx) or within 500m of each other.

The normal post-install notification for systems that fall outside this rule will still apply.
 
Fantastic chaps exactly what the forums for! Agree with the lack of response from paid membership organization, just shows what they are out for. !!
 
Small update - ENA have published Guidance Note 2/4 which covers details of the transition period from G83/1 to G83/2:

GUIDANCE NOTE 2/4
First issued 03 March 2011 – updated 06 October 2011
Second Issue 29 March 2012
Third Issue December 2012.

ENGINEERING RECOMMENDATIONS G83 AND G59
This guidance note was originally issued on 03 March 2011 and its main provision was to allow the use small scale generation of capacity greater than 16A per phase, provided it had been type tested to the requirements of G83/1-1 but with a modified over frequency protection setting.

It was updated on 06 October 2011 and again in March 2012 to allow the use of suitably sized inverters rated at 16A or less to be used with either G83/1-1 or G59/2-1 protection settings.

Now that G83/2 has been published the Distribution Code Review Panel wishes to see the following continuing interpretation:
• For all small scale embedded generation sets of up to 16A per phase, until 1 March 2014 it is permissible to connect to the general requirements of previous versions of G83 provided this is through an inverter or controller with a protection/control system that has either been fully type tested in accordance with G83/1-1, G83/2 or in accordance with G59/2. After 1 March 2014 it will only be allowable to connect small scale embedded generation of up to 16A per phase that complies with G83/2.
• Any application for connection above 16A per phase made on or after the 03 March 2012 must comply with the requirements of G59/2-1 in full.
