Big Marble Farms to sell excess power to City of Medicine Hat’s grid
The City of Medicine Hat will now purchase surplus electricity from Big Marble Farms after the greenhouse officially connected its generators to the city’s power grid.
A ribbon-cutting ceremony marked the milestone on Wednesday, allowing the 55-acre greenhouse to export excess power from its 12-megawatt on-site cogeneration system.
The generators run on natural gas and capture waste heat to help warm the greenhouse.
Until now, Big Marble could only generate electricity for its own use and had to shut the generators down when demand dropped.
