Plans to expand a Highland Perthshire hydroelectric station have been pulled after a series of objections over the impact on migrating salmon.

Local firm RDA Architects submitted plans for the SSE power station between Pitlochry and Killiecrankie last November.

The architects described the scheme as “sympathetic” but it drew criticism from Tay District Salmon Fisheries Board, who told Perth and Kinross Council officers it “posed significant risks” for young salmon migrating out of the River Tummel and adult fish returning.

In the organisation’s objection to the council, Dr David Summers said smolts (juvenile salmon) and near fully grown salmon were known to pass Clunie for up to eight months a year, and questioned the viability of the power station only running for the other four.
