Hatfield oversees the environmental management of the Waneta Expansion Project

Jul 26, 2012

Construction on the Waneta Expansion Project began in the fall of 2010, with completion projected for 2015. The Project, which is located on the Pend d’Oreille River in southeastern British Columbia, includes the addition of a second powerhouse located immediately downstream from the Waneta Dam and its existing powerhouse. The new powerhouse will share the existing dam’s hydraulic head and generate power from flow that would otherwise be spilled. Two Francis turbine units will be installed to produce up to a combined maximum capacity of 335 megawatts, stepped-up to 230 kV at the powerhouse and delivered to BC Hydro’s Selkirk Substation through a new 10 km transmission line.

Hatfield is responsible for the overall environmental management of the Waneta Expansion
Project. Hatfield has been involved since the pre-construction planning phase, and is on-site overseeing and managing environmental protection during Project construction. To date, there have been no major environmental incidences, and creative planning and mitigation have protected a variety of Listed Species (e.g., herptiles and birds), bears and their cubs, deer and moose and their newborn, and the aquatic environment. Hatfield will continue to be on-site through substantial completion of the Project managing final powerplant commissioning and site restoration.
