With a 24-acre bell pepper greenhouse and 24 additional acres under construction, Under Sun Acres is a greenhouse located in the province of Ontario (Canada), which operates 365 days a year and exports products throughout North America. In 2014, the company applied for the CHPSOP 2 (Combined Heat and Power Standard Offer Program), a program that aims to support the generation of energy from cogeneration plants and, after being approved, installed a 13.3 MW plant. The electricity produced is sold to the grid, the heat is used to heat the greenhouse and the CO2 is released for plant growth. With a 94% efficiency and a perfect integration with the greenhouse, we can consider this plant to be highly efficient.
