Culliton Creek

VVI Construction is proud to have been a part of the construction of The Culliton Creek Hydro Facility which is a 15-megawatt, run-of-river hydroelectric project located 20 kilometres north of Squamish. The facility will produce 74 gigawatt-hours of renewable, emissions-free electricity annually, enough to power about 5,900 homes. The project includes four main components:

  • Intake: Earth fill embankment and concrete spillway with inflatable weir to divert water from Culliton Creek.
  • Penstock: A 3.2-kilometre-long pipe (mostly buried) to deliver water downstream to the powerhouse.
  • Powerhouse: Reinforced concrete structure housing two 7.5 megawatt turbines and related equipment, and a concrete/rip-rap tailrace to return flow back to Culliton Creek.
  • Transmission Line: 12.6 kilometres of 69 kilovolt wood-pole transmission line.

The project is on the traditional territory of the Squamish Nation and Tsleil-Waututh Nation. An Impact Benefit Agreement for the project was negotiated between BluEarth Renewables and the Squamish Nation.

During peak construction periods on the project, there were approximately 80 workers on site. Members of the Squamish Nation made up 13% of the total workforce.

Greater than 80% of the development and procurement costs for the project were sourced in British Columbia, with an estimated $3 million spent locally in the Sea to Sky corridor. About 20 local vendors contributed goods and services to the project, including at least four Squamish Nation businesses.

Work on the Culliton Creek Hydro Project has been ongoing since 2002. The project has undertaken a rigorous permitting and review process, including an environmental review process which involved more than 12 federal, provincial, local and First Nations authorities and included the following:

  • Fish & Fish Habitat
  • Hydrology, Geomorphology, Instream Flow Requirements
  • Wildlife & Wildlife Habitat
  • Vegetation
