No drama with these llamas: New security guards patrol Sarnia Solar

Grazing sheep have protection at Enbridge solar site

It sounds like something AI dreamed up after too much sun—llamas and solar panels working in perfect harmony.

But this isn’t AI-generated whimsy. It’s the real (and really delightful) story of how Enbridge’s Sarnia Solar Project is managing its vegetation this year.

Meet the new guardians of the solar farm: two no-nonsense llamas named Leland and Callum. They’ve joined the team this season to protect the flock of 227 sheep tasked with grazing the site—and they’re surprisingly well-suited for the job.

“Llamas are incredibly effective and surprisingly fierce when it comes to protecting their herd,” says Ian Robertson, plant manager of Enbridge’s Sarnia, Tilbury, and Amherstburg solar sites in Ontario. “They’ve got strong herd instincts, and if a predator shows up, they’ll sound the alarm and stand their ground. They’re basically natural-born bodyguards.”

Like traditional guardian dogs, llamas offer protection, but they bring a few extra perks. They can handle the local climate, require little training and even pitch in on grazing.

That makes them an ideal fit for the Sarnia Solar Project, where sustainability, low-impact solutions and animal-powered land management all come together.

This is the second season of the project’s grazing program, launched in 2024 through a partnership with local farmers Brent and Meika Pelleboer of Angus Farms. The Pelleboers introduced 270 Rideau Arcott sheep to an 85-acre section of the 80-megawatt site to handle vegetation management the old-fashioned way—by eating it.

The approach helps keep grass and weeds from shading the solar panels, improving efficiency without the need for mowers or herbicides. It also supports biodiversity, with native plants like clover and wildflowers thriving and pollinators tagging along.

“The more we do this, the more we learn about how nature-based solutions can support clean energy in smart, sustainable ways,” says Robertson.

The sheep, for their part, have become local celebrities, even landing the cover of Enbridge’s 2024 Sustainability Report. But this year, it’s the llamas stealing the spotlight.

“It’s not every day you see a solar project guarded by llamas. It reminds us that energy infrastructure and environmental stewardship really can go hand in hand—and hoof in hoof,” Robertson says.
