Canyon Creek Pumped Hydro Energy Storage Project

This pumped hydro storage project was proposed by Turning Point Generation. The project will create two small off-stream water reservoirs – one atop a hill and one at the bottom. These two lakes will be connected by a pipeline with pumps, turbines and generating equipment near the bottom reservoir in a powerhouse. The storage capacity of this project is 75 MW for up to 37 hours of generation and 64MW of pumping. It is expected to begin operation in August 2021. 

The upper reservoir will be located in the southeast corner of the Obed Mountain Coal Mine surface lease. It will be created by utilizing the existing topography and building a berm to impound water. It will cover up to 40 hectares (90 acres), and hold up to 2.5M m3 of water when full. A small intake house adjacent to the berm will house safety shut-off gates and supporting equipment. 

The off-stream man-made lower reservoir will be located on a lowland plateau near the Athabasca River. In recent development, project developers decided to move the lower reservoir further away from the Athabasca River to minimize impact to the local biodiversity zone. It will cover up to 32 hectares (79 acres). The project will require a fill of fresh water, which is planned to be sourced from the Athabasca river. Once constructed it will be filled and each year a small amount of make-up water will be needed to compensate for evaporation.

The project received approval by the Alberta legislature on December 11, 2018, and was then approved by the Alberta Utility Commission on December 21, 2018.
