The Los Cocos and Quilvio Cabrera projects in Pedernales province, in the south of the country, have a combined capacity of 33MW. The projects use Vestas 1.8MW turbines.
They were developed by domestic power companies Punta Cana-Macao and EGE Haina at a cost of around $100 million.
Gamesa is also developing a wind project on the island. Last year, the Inter-American Development Bank (IADB) announced a loan of $50.7 million for the $127-million Parques Eolicos del Caribe.
In addition to Gamesa the consortium includes Dominican real estate firm Grupo Delta Intur, and businessmen Aquiles Mateo and Miguel Angel Muniz.
The projects will comprise 25 Gamesa G90 turbines and be located close to the northern coast of the Dominican Republic, which shares the island of Hispanola with Haiti.
The Caribbean nation introduced laws in 2007 designed to encourage renewable-energy generation, but it is only now that projects are receiving the funding they need to get off the ground.
