Transmission Access Charge Deferral Account True-up
ATCO Electric Ltd. (“ATCO”) applied to the AUC for approval of its 2014 transmission access charge deferral accounts (“TACDA”) true-up, which it proposed to collect through Rider G. Each electric distribution company is charged by the Alberta Electric System Operator (“AESO”) for transmission services in relation to customers in their distribution service areas. ATCO’s TACDA collects these charges as a flow-through of the AESO’s tariff charges during its performance based regulation term.
ATCO applied for a net 2014 TACDA refund of $4.225 million, set out as follows:
ATCO proposed to refund the 2014 TACDA effective from January 1, 2016 to December 31, 2016.
The AUC accepted ATCO’s calculations as reasonable noting that the cost allocation methodologies were also reasonable, or were previously approved by the AUC in prior decisions. The AUC directed ATCO to identify any under-frequency load shedding credit amounts as a separate column in its future TACDA applications.
ATCO submitted that a twelve-month collection period would result in a maximum change to customers’ monthly bills of 3.3 percent, and would therefore not constitute a rate shock. The AUC agreed with ATCO’s submissions.
Accordingly, the AUC approved ATCO’s application as filed, to refund $4.225 million to customers effective January 1, 2016 to December 31, 2016.
