PIERRE, S.D. -

The largest solar farm in South Dakota is gearing up to start producing electricity.

Officials held a ribbon-cutting ceremony Monday for the 9-acre, $2 million solar farm at the Pierre airport, after about two months of construction. The Capital Journal reports it will provide enough power for about 200 Pierre households.

The project is a joint venture involving the city of Pierre, Minneapolis-based Geronimo Energy and Sioux Falls-based Missouri River Energy Services. The solar farm is expected to start generating power by the end of the week.

University of South Dakota researchers will study the facility's energy output.
