The £2.5bn project will feature 102 Siemens wind turbines, which will be installed in the southern North Sea, about 26 miles off the coast.
Construction work is expected to start in 2017, and the project is anticipated be fully operational during 2020.
After completion, the project will generate enough energy for about 500,000 homes or the majority of the households in Suffolk and Norfolk.
The project will likely feature an offshore substation to collect the energy from the turbines and transform it to a form suitable for transfer to shore.
Two offshore export cables, each about 85 km in length, will transfer the electricity to shore and a landfall site with onshore transition pits will link the offshore and onshore cables.
A planned onshore substation adjacent to the existing substation at Bramford, Suffolk, will link the windfarm to the National Grid.
The UK Department of Energy and Climate Change said it will guarantee £119.89 per MWh of electricity for the project.
ScottishPower Renewables, East Anglia ONE project director, Charlie Jordan said: "East Anglia ONE will deliver substantial environmental benefits for the UK, it will stimulate considerable UK investment, and it will support thousands of jobs.
"ScottishPower Renewables is leading the way with its approach of actively working towards a target of at least 50% UK supply chain content over the lifetime of the East Anglia ONE project."
