One of the largest solar energy initiatives in Minnesota, the Aurora project, has been completed, its owner said Tuesday.

The Aurora project features 16 separate solar power plants in Minnesota that together will provide electricity to Xcel Energy under a long-term contract. Aurora, which cost $290 million, is owned by Enel Green Power North America and can produce 100 megawatts of power, enough for more than 17,000 homes. A megawatt is 1 million watts.
