How Just Energy Operates in ENMAX’s Service Areas
Two types of companies work together to ensure you can power your home: utility companies and energy providers. Retail electricity providers (REPs), like Just Energy, are the companies you actively choose to sell you the electricity your household uses. You buy your electricity through an energy plan and pay the plan’s stated rates. REPs also manage your account, including billing, contracts, and customer service.
Utility providers like ENMAX Power handle the physical delivery of electricity. ENMAX owns and operates the local power grid, including substations, transmission lines, poles, and meters. It ensures electricity reliably reaches homes, reads your meters, and responds to outages or infrastructure issues. ENMAX is your mandatory utility provider if you live within its service area.
How to Contact ENMAX
Contact ENMAX for meter issues and questions or to report an outage. For emergencies like downed or sparking power lines, call 911.

Does ENMAX offer electricity plans?

Is there a way to lower TDU charges from ENMAX?
No, you can’t lower ENMAX TDU charges because they’re set and regulated by the Alberta Utilities Commission. Everyone in your area pays the same TDU charges regardless of their energy provider.
