GE Jenbacher Engines Powering First North American Commercial Greenhouse Plant
North America’s first GE-designed greenhouse cogeneration plant recently held its grand opening ceremony; Canadian government and business leaders were in attendance for this event. Great Northern Hydroponics, a division of Detroit-based Soave Enterprises, installed the 12MW commercial greenhouse power plant at Soave’s 55-acre tomato greenhouse complex in Kingsville, Ontario.
The power plant, powered by four of GE Energy’s Jenbacher gas engines cogeneration modules, was among seven natural gas-fueled combined heat and power (CHP) projects approved by the Ontario Power Authority in 2006 to showcase how advanced cogeneration technologies could help make industrial plants more energy independent, improve local grid reliability and support Canada’s clean and renewable energy goals. Surplus power from the greenhouse power plant is being sold to the local grid under a 20-year contract with the Ontario Power Authority. The plant supplies enough electricity to Ontario’s transmission grid to power 12,000 to 15,000 Canadian homes annually.
In addition to generating power and heat to support greenhouse operations, the power plant also treats the gas engines’ exhaust, enabling CO2 from the exhaust to be recycled and applied as a special fertilizer to enhance greenhouse crop production. “Our inaugural greenhouse cogeneration project was made possible because of Ontario’s commitment to energy efficiency and initiatives to add significant amounts of energy from cogeneration to the provincial power grid,” said Guido van het Hof, president of Great Northern Hydroponics. The cogeneration plant allows Soave to control its greenhouse operating expenses and improve its competitive position against other growers in North America, van het Hof explained.
The project also will support Ontario’s renewable energy goals because high efficiency, dispatchable cogeneration projects—including the Soave Hydroponics project—are helping the integration of renewable energy projects into the grid, van het Hof added. The Soave plant features four ecomagination-certified, JMS 620 Jenbacher gas engines, heat recovery and exhaust treatment equipment, noise abatement and systems controls. The complete greenhouse cogeneration system was supplied by DDACE Power Systems, GE’s Jenbacher engine distributor for eastern Canada. H.H. Angus and Associated Ltd. of Toronto provided engineering services for the North American reference plant.
