Private wire arrangement
The Home Quality Mark One, Technical Manual SD239, England, Scotland & Wales, published by BRE in 2018 defines a ‘private wire arrangement’ in the context of the HQM for low or zero carbon technology installations, as
‘…where any electricity generated on or near the site is fed directly to the building being assessed, by dedicated power supplies. If electricity is generated which is surplus to the instantaneous demand of the building, this electricity may be fed back to the national grid. The carbon benefit associated with any electricity fed into the grid in this manner can only be allocated against an individual installation or building.’
BREEAM UK New Construction, Non-domestic Buildings (United Kingdom), Technical Manual, SD5078: BREEAM UK New Construction 2018 3.0, published by BRE Global Limited states:
'The carbon benefit associated with any electricity fed into the grid in this manner can only be allocated against an individual installation or building. In cases where a building is supplied by a communal installation, no carbon benefit can be allocated to buildings which are not connected to the communal installation.'
