Assistance for Areas with High Electricity Distribution Costs (AAHEDC)
AAHEDC recovers costs for The North of Scotland which is currently the only area specified to receive assistance.
Who pays? We recover the assistance amount 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.
This replaces an earlier arrangement, commonly referred to as 'Hydro Benefit'.
Each year, the AAHEDC tariffs are published by 15 July and take effect from 1 April retrospectively.
For more information, here's our handy guide:
