Renewable energy · High voltage · South Australia
We terminate and joint high voltage cables.
We work on substations and switchgear. We do the work most electricians can't.
01 · About
The future of renewable energy at Earthed.
Earthed started in the Adelaide Hills, founded by Caleb Vears in 2024 off the back of ten years working in distribution power systems with a strong focus on renewable energy. Since then Earthed has worked alongside some of the world's leading renewable energy companies, right here in South Australia. We hold a real focus on maintaining a healthy working environment, using our craft to implement strict safe operating procedures inside our in-house safety system. Our clients get the confidence of knowing Earthed was there.
