Nordex will supply 81 AW125 3MW turbines to an unnamed customer with installation expected to begin in early 2017.
It is the first publicised order Nordex has received for Acciona-designed wind turbines.
Acciona Wind Power had a strong presence in the Americas, prior to the merger.
Nordex closed its US factory in 2014 in a restructuring move and only 11.7% of its orders in 2015 were from the Americas region.
The Acciona 3MW platform has been installed at a number of other Texan wind projects, including the 300MW Green Pastures site owned by private asset manager Capital Dynamics, and the 165MW Cameron site owned by Swedish furniture firm Ikea.
