ABOUT AUX ENERGY
Sustainable energy made simpler.
AUX Energy makes sustainable energy simple and affordable for the municipalities, businesses, and Indigenous communities driving Ontario’s economic future. A Hydro One company, built to deliver outcomes — not just install equipment.
Solving Ontario's energy challenges, one project at a time.
AUX Energy exists to make sustainable energy affordable and accessible for Ontario’s customers — and to support Ontario’s broader economic future through reliable, lower-cost power.
We work with municipalities under net-zero pressure, commercial and industrial operators chasing operational savings, and Indigenous communities building energy sovereignty. Our role is to make complex things simple: solution design, financing navigation, turnkey delivery, and long-term operations — all under one accountable partner.
A Hydro One company, AUX brings the operational rigour of Ontario’s primary transmission utility to every deployment. Our balance sheet, our scale, our regulatory expertise — they all work for the customer.
Mission & Values
What we stand for.
Four principles that guide how we deliver sustainable energy for Ontario.
Integrity
Honest assessments and transparent financial models — we’ll tell you when a project doesn’t make economic sense for your bottom line.
Affordability
We’re paid to deliver customer savings, not to sell equipment. Every project we ship has a Day-1 economic case.
Simplicity
We turn complex things — financing, regulation, interconnection, operations — into a clear path forward for our customers.
Outcomes
Immediate savings, 25-year reliability, and measurable economic alignment with your operational goals.
Utility-grade scale. Customer-grade simplicity.
AUX brings utility-scale operational rigour to every sustainable energy deployment — backed by the balance sheet, regulatory expertise, and Ontario reach of a Hydro One company.
When you partner with AUX, you’re working with a team that’s accountable, well-capitalized, and structurally aligned with Ontario’s sustainable energy future. We don’t deliver pitches — we deliver projects that pencil out.
