The Alberta Utilities Commission on Sept. 16 approved an application from ATCO Power Canada Ltd. for a finding that the company has met the statutory requirements of discontinuing the operation of the Rainbow Lake Power Plant.
“After consideration of the record of the proceeding, and for the reasons outlined in this decision, the Commission finds that ATCO Power has met the requirements,” said the Sept. 16 order.
Alberta Power (2000) Ltd., a wholly owned subsidiary of ATCO Power, is the owner of the Rainbow Lake Power Plant. The plant is located approximately 12 kilometers southeast of Rainbow Lake, and consists of three simple-cycle natural gas-fired turbines. The three units have a capacity of 26 MW, 40 MW and 21 MW, respectively. Units 1 and 2 began operation prior to June 1971. Unit 3 was added in 1993.
ATCO Power filed an application, on behalf of Alberta Power (2000) Ltd., with the commission to provide notification of the planned discontinuance of operations, disconnection, decommissioning and salvage of the Rainbow Lake plant. The application was registered on Aug. 29, 2016. ATCO Power stated that the power plant would formally cease operations on Nov. 13, 2016.
ATCO Power said it had consulted with Alberta Environment and Parks (AEP) and would be following its guidance for the discontinuance of operation, disconnection, decommissioning and salvage of the plant. ATCO Power stated an application for the demolition, salvage, remediation and reclamation would be submitted to AEP following the completion of the current environmental site assessment and demolition planning activities.
