When completed, the site is set to be the home to 13 turbines which will be capable of producing 30 megawatts of "clean green energy", which would be enough power for over 16,000 homes.
The windfarm will be located two-kilometres north of Ashington, near to the Rio Tinto Alcan Lynemouth Smelter.
Keith Anderson, director of ScottishPower's renewable division, said the firm was "delighted" with the "findings of the planning appeal process".
He added: "We now look forward to progressing construction of the project and adding renewable energy generation to the areas long standing industrial heritage."
