The North Dakota Industrial Commission approved a $500,000 renewable energy grant for a greenhouse project planned for the Spiritwood Energy Park Association industrial park near Jamestown, N.D., according to Connie Ova, CEO of the Jamestown/Stutsman Development Corp.

The project will use waste heat from the 99-megawatt Spiritwood Station to heat the greenhouse. Waste carbon dioxide from the Dakota Spirit AgEnergy ethanol plant would also be fed into the greenhouse to increase production. The grant will facilitate research associated with the CO2 capture and transportation system, according to Jonathan Russo, business development manager for the North Dakota Department of Commerce.

Plans for the 30-acre commercial greenhouse were announced in September with a tentative plan to begin construction in the spring of 2021. The project is being developed and would be operated by Houweling Tomatoes.

Plans call for the completion of the project by the fall of this year if construction begins this spring as planned.

The cost for the project is estimated between $30 million and $35 million. When operational, the greenhouse would support about 100 jobs while producing 20 million pounds of produce each year.
