Private wire

Private wire systems are localised electricity grids connected to the local distribution networks but linked to privately owned central plant which produces electricity. This enables them to operate a stand-alone supply in the event of the national grid failing, providing localised energy security. The business case for private wire supply is driven by the fact that off-grid generation generally avoids network charges and statutory costs.^[1] Ofgem's "Significant Code Review" in the UK, launched in August 2017,^[2] includes private wire supplies within its scope.^[3]
