Scotland's biggest offshore wind farm has begun generating power.
Seagreen, which is located about 27km (17 miles) off the Angus coast in the North Sea, has been in development for more than a decade.
When fully operational, it will have 114 turbines and generate 1.1 gigawatts (GW) of electricity - enough to power about one million homes.
Each will have a maximum tip height of 187m (614ft), which is about twice the height of the tower housing Big Ben.
Seagreen is also the deepest wind farm to be fixed to the seabed in the world.
The £3bn project is a joint operation between SSE Renewables and TotalEnergies, and it is expected to be completed next year.
The companies say it will eventually displace more than two million tonnes of carbon dioxide from electricity generated by fossil fuels every year.
At the peak of its construction, the project is expected to support about 3,000 jobs directly and indirectly.
The turbines' jackets - or foundations - were assembled at the Port of Nigg on the Cromarty Firth.
