The project, which was initially developed by Infinergy, involved installation of 59 wind turbines with a combined power generation capacity of up to 177 MW near Dufftown.
Following approval from the Scottish ministers in December 2011, the project was awarded a Contract For Differences (CfD) in February 2015 at a strike price of £82.50 per megawatt-hour.
However, due to advancement of improved turbine technology, the company has later filed an application to redesign and boost capacity of the project to approximately 200MW.
Upon completion in 2018, the 200MW wind park is expected to generate clean electricity required to power up to 138,000 households.
EDF Energy CEO Vincent de Rivaz said: "Today’s announcement, just weeks before the international conference on climate change in Paris, confirms EDF Energy’s commitment to lead in UK investment in low carbon electricity.
"That means investment in wind and nuclear electricity generation with an increasing focus on the development of Scottish renewables.
"In taking on the development of the largest planned onshore wind project in Scotland, we intend to boost its output using our world-leading research and development expertise."
With the new deal, EDF Energy Renewables, which is a joint venture between EDF Energy and EDF Energies Nouvelles, will partner with Infinergy to develop and construct the wind power plant.
EDF Energies Nouvelles CEO Antoine Cahuzac said: "With around 700 MW of wind projects in construction and operation in the UK as well as a large portfolio in development, EDF Energy Renewables is keen to work with Infinergy to start the building of this great project and progress the planning applications."
Infinergy expects the new power plant to contribute to the Scottish Government’s renewable energy targets to ensure greater diversity and security of electricity supplies.
