Reasons for a Federal Assessment

On July 30, 2010, it was determined that an environmental assessment was required in relation to the project because the Parks Canada Agency considered providing federal lands and Natural Resources Canada considered providing financial assistance to the proponent.

Project Description (as posted in the Notice of Commencement)

BC Hydro is proposing to install a large-scale energy storage unit near the town of Field, B.C., to enhance supply reliability for the townsite of Field. The energy storage unit will be installed at the Yoho National Park Operations Centre, located approximately 4 kilometres west of Field. The primary components and structures of the proposed project are a large-scale energy storage battery (1 MW) together with the associated control systems and interfaces and connections to the existing electrical grid. A small propane-fuelled emergency generator (~175 kW) will also be installed to maintain internal battery heat when the battery is discharged below 20 percent storage capacity.

Final Decision

A decision was taken on June 10, 2011 and was that the authorities may exercise any power or perform any duty or function with respect to the project because, after taking into consideration the screening report and taking into account the implementation of appropriate mitigation measures, the authorities are of the opinion that the project is not likely to cause significant adverse environmental effects.
