Proposed grid voltage changes

 

The Energy Networks Association intends changing the Electricity Safety Quality and Continuity Regulations (section 27) to widen the permitted voltage range in GB.

The Announcement is here on the ENA site.

Here's the present version of that Regulation:

ElectricityRegs S27

 

The engineer who brought this to my attention also observed that DNOs might actually reduce the LV levels closer to 230v instead of 240v as at present.
That wouldn't require a change to the regulations because 230v is already the 'designated voltage'.

The change could be effected by reducing the 11kV output from Primary Substations over a longish period of time.

 

It has implications for grid upgrades.

An EV charger or Heat-Pump requiring 4kW at a given moment in time would draw 4.3% more current at 230v than at 240v.

Consequently, a greater proportion of the Distribution Grid would suffer thermal overload, and require upgrading.
DNOs would expect Ofgem to approve such recabling, the costs of which would be met by higher electricity bills in that Region.

Bold move by Ireland. I wonder what their installation standards and quality is like.

GB could achieve the same as Ireland if DESNZ understood the problems better.

Instead of increasing the grant from £5k to £7500, we should've put the additional £2500 into an inspection regime run by the local Building Control office.
Whilst on-site the surveyors would also have been able to check related works which might've been part of an ECO4 package.
We've really missed a chance to raise the standards.

This was sent to me last week. More quality ECO4 work.

1768045319521
1768045319631
1768045320055

 

Someone's got their wires crossed there or it's deliberately fake. There is no way on this earth that is a new Eco4 install.

If it's anything to do with one then it's what they found when they started the job and had to take it out. That's a DIY job in the pics.

@deltona, are you speaking out of authority based on demonstrable fact or expressing an opinion based on not feeling able to believe the claim?

Crazy if they were getting away with DIY standards. Could the installer have recruited in-loco? 😀
