Plans for an offshore wind farm near Tiree have been delayed by Scottish Power Renewables.
The company said the Argyll Array scheme had been put on hold for 12 months.
The firm said it would use the time to study reports on the potential environmental impact of the project, alongside other agencies.
There are concerns it could affect basking sharks and seabirds, including Great Northern Divers.
The RSPB has previously said the area is rich in marine life, with dolphins, killer whales and basking sharks all sighted around the island.
It said the area is also regularly used by foraging and passage seabirds and other migratory bird species.
The Argyll Array site is located 5km off the coast of Tiree, and covers about 360 square kilometres.
A lease for the offshore site was granted by the Crown Estate in October last year.
But ScottishPower Renewables said its plans had now been halted for a year.
