The fish farm located in Loch Odhairn is operated by the Scottish Salmon Company.

In March 2007, Scottish and Southern Energy proposed to build a converter station above the village and to use Gravir as the Western Isles landfall for a sub-sea interconnector cable, to export electricity generated from two proposed large scale windfarms at Eishken and Pairc across the Minch to mainland markets.

On the Lewis side, it would enter the mouth of Loch Odhairn at the fish farm and run up the length of the sealoch under the shore at its head, by the old schoolhouse, and then be buried across crofts to the hilltop to the converter station.

One network of overhead lines or pylons would run to the planned Pairc windfarm and to Eishken.

Another run of overhead lines on wooden poles would leave Gravir by following the village road heading for the sub-station by the River Creed.
