The Berwick Bank project, one of the world's largest offshore wind farms, has been approved by the Scottish government.
The huge North Sea development, 23 miles off the east coast, could generate enough electricity to power every household in Scotland - twice.
Reacting to news of the 4.1GW development's approval, Aberdeen & Grampian Chamber of Commerce’s chief executive Russell Borthwick said: “This is great leap forward for Scotland’s offshore wind industry – with fantastic opportunities ahead for the energy workforce and the world-class supply chain based here.
“Projects of this scale are essential to a successful energy transition – decarbonising our energy system while reindustrialising our economy.
“Businesses in the North-east of Scotland – our ports, service companies and firms pivoting from oil and gas to renewables – stand ready to help in driving major projects like these forward.
“That said, we hope the Scottish Government has learnt lessons from Berwick Bank. If we want to accelerate the transition, we cannot have projects sitting on the ministers’ desks awaiting consent for well over two years. Resources need to be beefed up and decisions must be made more swiftly.
“The next challenge for this project sits with the UK Government in ensuring they are big and bold when it comes to the next Contracts for Difference round – so that projects like this can move through consent to build and on to powering homes and businesses.”
The BBC reports Deputy First Minister Kate Forbes said: "The decision to grant consent to Berwick Bank is a major step in Scotland's progress towards achieving net zero and tackling the climate crisis, as well as supporting national energy security and growing our green economy."
UK Energy Secretary Ed Miliband said: "We welcome this decision which puts us within touching distance of our offshore wind targets to deliver clean power by 2030 – boosting our mission to make Britain a clean energy superpower."
He added it marked a "huge step forward" in the UK's energy security and "getting bills down for good".
Scottish Conservative net zero and energy spokesman Douglas Lumsden highlighted the importance of a mix of energy sources, including oil and gas, in providing affordable power and energy security in Scotland.
He said: "Scotland will only prosper with a realistic energy policy that draws on nuclear, oil and gas and renewables.
"The hostility of both the SNP and Labour governments to North Sea oil and gas is costing an estimated 400 jobs a fortnight and increasing our reliance on imported fossil fuels."
SSE Renewables said the project could create thousands of jobs and inject £8.3billion into the economy over its lifetime.
