Stanton Bros. Ltd. set to become first agricultural supplier into Ontario grid

The infrastructure needed to scrub methane gas produced by the digester is installed at the Stanton dairy farm near Ilderton.

An Ilderton-area dairy farm is set to become the first agricultural contributor to Ontario’s natural gas grid, with only minor steps remaining to connect to the pipeline passing along the front property line.

“We’re very close. Our end of the project is complete. We’ve got gas flowing to the road,” explained Murray Logan of Rural Green Energy, a Guelph-based company working alongside Shakespeare-based Stonecrest Engineering and the farm’s owners on this first-in-the-province enterprise.

Stanton Bros. Ltd. began its foray into biogas-fuelled renewable energy production with an on-farm digester powering three 250-kilowatt electricity generators. The facility takes in both on-farm and off-farm organic wastes.

This summer a second biodigester was completed. Instead of powering generators, however, the methane from this unit is purified and pressurized and sent out the laneway to connect to the natural gas grid.

Stonecrest engineer Nicholas Hendry is scheduled to explain the details of the project during Outdoor Dairy Days, presented by Canada’s Outdoor Farm Show Sept. 21-22.

There are currently methane biodigesters feeding Ontario’s natural gas grid operated by municipal or industrial interests in the Niagara Region, GTA and Leamington. In British Columbia and Quebec, there are already on-farm biodigesters supplying what’s identified as renewable natural gas (RNG). But Stanton Bros. is the first operator of an on-farm digester in Ontario to install the necessary infrastructure to supply RNG.

Pipeline operator Enbridge is constructing a compound at the road, Logan said, to test the gas from the biodigester and further purify if necessary to meet the provincial grid specifications. But the contract signed by Stanton Bros. for supplying the grid isn’t with Enbridge. Instead, it’s with British Columbia-based utility Fortis. Logan told Farmtario the natural gas regulator in BC approved the Fortis/Stanton Bros. contract in the spring of 2020.

“We’re excited about it,” Logan said. “With all the regulations and getting the necessary contracts and approvals, it has taken a long time getting to this point.”
