Teesside A&B will cover an area approximately 600 kilometres square and with 400 turbines. It will be 165 kilometres from the UK's coast, one of the country's furthest from shore.
Despite the distance from shore, the project is located in relatively shallow waters. Depths in the whole zone range between 18 and 63 metres.
The Forewind consortium, comprising SSE, RWE Innogy, Statkraft and Statoil, is developing the project. Its 2.4GW Creyke Beck A&B projects, also part of the Dogger Bank zone, were approved in February.
Forewind said the Teesside A&B projects could create up to 4,750 jobs, mostly in the northeast region of England.
The 7.2GW Dogger Bank zone also includes the 2.4 GW Teesside C&D projects, currently in the consultation phase.
Forewind will now be required to make a final investment decision on the project, which may prove difficult, as there is uncertainty over the levels of support the government will make available.
RenewableUK chief executive Maria McCaffery said: "The ambition of the industry needs to be matched by a vision from Government which is backed up by firm commitments on the levels of financial provision which will be available. The industry is set to play its part — but it needs a fair wind from Westminster in order to do so."
