Change to City of Lethbridge Electric utility Charges “Rider C”
Effective January 1, 2013 Rider C will be increased from a charge of $0.003 per kWh to a charge of $0.0053 kWh.
How does this affect my electric bill?
Example – an average residential consumer using 650 kWh per month was charged $1.95 for Rider C in 2012. In 2013 this will increase to $3.44.
Why is this happening?
The new provincial rate structure for the collection of transmission costs was approved effective July 1, 2011. In 2012 the provincial government froze all transmission and distribution costs while they conducted a review of electric charges. The review has been completed and the Alberta Electric System Operator (AESO) has posted the new rider that will affect all customers. The City of Lethbridge passes on the costs as we are advised of them.
What will happen next?
Rider C will continue to be adjusted as required
