Scotland's largest offshore wind park is to be officially opened by Prince Charles later.
Beatrice Offshore Wind Farm, located approximately 1
The £ 2.65 billion project, which involves 84 enormous turbines, came fully online in May, achieving 588 MW of power.
It is Scotland's largest renewable energy source.
Development, construction and operation were led by SSE Renewables in a joint venture with Copenhagen Infrastructure Partners and Red Rock Power Limited.
Construction started in May 2016 and SSE said it was completed on time and £ 100m under budget.
Part of the project revolved around the rebuilding of buildings in Wick, Caithness City where around 90 employees will look after the operation and maintenance of the wind farm during its 25-year lifespan.
Prince Charles, known in Scotland as the Duke of Rothesay, will visit the offices of Beatrice Offshore Windfarm Limited and SSE Renewables in Wick to mark the official opening.
The two waterfront buildings used for the Wick base were originally designed by the renowned Scottish architect Thomas Telford for use in the herring industry.
The electricity produced by Beatrice travels along undersea cables and underground cables before arriving on land near Keith in Moray and connecting to the Blackhillock transformer station.
Great, but how big?
The world's largest offshore wind park is Walney, off the coast of Cumbria. It is said to be capable of generating sufficient power for 600,000 homes.
Two other offshore sites have more impact than Beatrice:
- The London Array, located 10 miles north of Ramsgate in the Thames Estuary.
- Gemini Wind Farm, in the Netherlands.
The others in the top 10, in order of production, are:
- Good Wind, in Germany
- Gwynt y Mor, outside Llandudno in Conwy county.
- Race Bank, off the coast of Norfolk and Lincolnshire.
- Greater Gabbard, off the coast of Suffolk and Essex.
- Dudgeon, off the Norfolk coast.
- Veja Mate, in Germany
Claire Mack, CEO of Scottish Renewables, said the scale of the project was "truly staggering".
"Scotland has a quarter of Europe's offshore wind resource and Beatrice represents one of the first steps in tapping it," she said.
"As our offshore wind projects continue to expand, we will see the environmental and economic benefits of offshore winds growing across Scotland, with jobs and investments transforming communities, as they already are in Wick."
She added: "With the right support from the government, a supply chain that is competitive in price, quality and schedules and the industry's commitment, the offshore wind has a bright future in Scotland as we work to meet some of the world's most challenging climate change targets. and build a smart energy system with renewable energy at heart. "
The Beatrice project is the fourth largest offshore wind farm in the world, with only two projects in England and one outside the Netherlands generating more energy.
However, the Beatrice array is built in deeper water, with mantle foundations each weighing in at around 1,000 tonnes installed at sea depths of up to 183 feet.
Earlier this month, it was announced that wind power production in Scotland was at a record high during the first six months of 2019.
Figures from Weather Energy calculated the energy produced by turbines could power every home in Scotland and parts of Northern England .  WWF Scotland described the trend as a "wind power revolution".
