The UK government is to look at reducing the 2p per unit electricity surcharge imposed on households in the Highlands and islands.
The proposal is to "ensure that they pay no more for electricity distribution than consumers in the next most expensive region.
There are 14 grid operators across the UK, each applying different surcharges.
The government wants the Western Isles surcharge to be reduced to the next lowest level.
It estimates that this could save an average island household around £30 per year on their electricity bill.
Families in the north of Scotland have to pay an additional 2p per unit more than elsewhere as all electricity suppliers face different costs for transporting electricity across the grid in different parts of Great Britain.
It means a Western Isles household pays around 15% more than a family in Glasgow using the same amount of electricity.
North of Scotland grid operator SSE wants these transport costs to be flattened out so that there is one standard charge for every customer across Great Britain.
