Natural Resources Canada (NRC) has granted environmental approval to development of six hydroelectric plants in Cloudworks Energy Inc.’s Harrison Hydro project near Harrison Lake in British Columbia.
The federal environmental agency declared September 19 that the project, totaling 151.8 MW, is not likely to cause significant adverse environmental effects. It also required Cloudworks to carry out mitigation measures to address birds, fish, air and water quality, surface and bedrock features, vegetation, and noise levels.
For its review, the NRC’s Canadian Environmental Assessment Agency divided the six run-of-river plants into two groups according to location:
o Lower Lillooet project: 27.6-MW Douglas Creek, 25-MW Fire Creek, and 21-MW Stokke Creek; and
o Upper Harrison project: 16.7-MW Tipella Creek, 33.5-MW Upper Stave River, and 28-MW Lamont Creek.
NRC said Indian and Northern Affairs Canada, Fisheries and Oceans Canada, and Transport Canada previously ruled the projects were not likely to have significant environmental effects. Working in parallel with the federal agencies, British Columbia’s Environmental Assessment Office also issued environmental certificates approving the plants. (HNN 10/5/06)
Cloudworks said preliminary work began in February on a construction camp for the six plants. The developer expects construction to be complete in November 2010.
All six plants are to deliver power through a new substation at the north end of Harrison Lake, which will connect with a 360-kV transmission line of BC Hydro. BC Hydro awarded power purchase contracts in July 2006 to Douglas Creek, Fire Creek, Stokke Creek, and Tipella Creek, grouped under the name Kwalsa Energy LP; and to Upper Stave River and Lamont Creek, grouped under the name Upper Stave Energy LP.

Andritz VA Tech Hydro to supply turbine-generators
Andritz VA Tech Hydro announced it received a US$50 million order from contractor Peter Kiewit Sons Co. to supply a total of 14 turbine-generators to the six Harrison Hydro plants.
The manufacturer is to supply eight identical six-jet Pelton turbines with a maximum output of 13 MW, plus inlet valves, generators, and digital speed governors to the Kwalsa group plants, Douglas Creek, Fire Creek, Stokke Creek, and Tipella Creek.
Of the Upper Stave group plants, VA Tech Hydro is to supply two vertical five-jet Peltons of 15 MW each for Lamont Creek, and three horizontal Francis turbines of 12 MW each and a horizontal Francis of 5 MW for Upper Stave River. That equipment also will include inlet valves, generators, and digital speed governors.
To help fill the order and to serve the fast pace of hydro development in British Columbia, Andritz VA Tech Hydro said it would open a new branch office in the Vancouver area in late 2007.
