The facility will develop blades of up to 70 metres in length for offshore turbines. It will also be able to manufacture and test the blades.
The EDA said the project would look for "production efficiencies" that would boost manufacturing of wind blades in the US.
Acting US commerce secretary Rebecca Blank said: "Strengthening research and development in support of an innovation economy is vital to creating jobs and maintaining global competitiveness.
"This EDA grant will provide cutting-edge technologies that will advance wind energy generation and serve as a catalyst for job creation in rural Maine."
Currently, the longest blades in development are for the Vestas V164 7MW turbine. The machine is set to be tested this year.
