Assistance for areas with high electricity distribution costs (AAHEDC)

Assistance for areas with high electricity distribution costs (AAHEDC) replaces an earlier arrangement, commonly referred to as 'Hydro Benefit'. The North of Scotland is currently the only area specified to receive assistance. We recover the assistance through a charge on all suppliers. This is passed on to Scottish Hydro Electric Power Distribution Ltd, so distribution charges in the North of Scotland can be reduced.
