Battery Battery Storage Gets A £1m Boost

[Worcester]

By implication would this mean if you already have a G59 approval and the battery system can't exceed the approved capacity there would be no need for further consent?

If I put a hard line regulatory hat on, I would say that you are adding a new generator to the installation and as such I either want to see type approvals, and / or witness testing.

What would you do if you added more PV to a system with that pre-existing approval? (Even if you aren't going to claim any form of Feed in Tariff for the extra PV)

Same rules would apply.

If the DNC is changing, then wouldn't the documentation associated with the original application need updating? I'd be surprised if we see type-tested solutions, and external G59 relays are going to add at least £1500 to the system cost, plus circa £500 for site testing, plus whatever the DNO charges should they insist on the pleasure of their company

thing is, these systems aren't designed to export onto the grid at all, they're zero export devices, so as long as they have G83 protection settings I don't really see that it has anything to do with the DNO.

Completely agree, I believe discussions with DNOs are ongoing, but it certainly seems that some of them are considering some systems as adding generation capacity, for some strange reason. Maybe it will become clearer/more sensible soon
