The Courtenay Wind Farm near Jamestown will cost about $300 million. North Dakota's Public Service Commission in August gave Xcel Energy permission to buy the project from Geronimo Energy, which had problems securing financing.
Xcel earlier had agreed to buy all power produced from the 100-turbine wind farm that will have the capacity to power up to 105,000 homes.
KQDJ radio reports that a ground-breaking ceremony was scheduled Friday. The project should be completed next year.
