The 315MW Sheringham Shoal offshore wind farm has received consent from the UK government's Department of Business, Enterprise and Regulatory Reform (BERR).
This consent means the developer, joint-venture company Scira Offshore Energy, is a step closer to constructing the wind farm on the 35 km2 site in the Greater Wash.
It is now just awaiting the investment decision from its majority-owner, StatoilHydro.
Scira Offshore Energy is 55 per cent owned by StatoilHydro headquartered in Norway, and 45 per cent owned by Dutch company Evelop - a subsidiary of sustainable energy company Econcern.
The StatoilHydro management board will make the final investment decision on the project before the end of this year.
If sanctioned, construction will begin in 2009 with the wind farm becoming operational in 2011.
The proposed wind farm will consist of 88 turbines with an annual electricity production of around 1.1TWh, enough energy to power around 220,000 homes.
