Canada utility seeks geotechnical surveying, drilling for 1,100-MW Peace River Site C hydro

Canadian utility BC Hydro seeks bids for geotechnical surveying and drilling services for the 1,100-MW Peace River Site C hydroelectric project in British Columbia. Bids in separate solicitations are due June 12 and 14.

BC Hydro submitted an environmental impact statement in January for the US$7.8 billion Site C project, to be located on the Peace River in northeastern British Columbia. Site C would be the third hydroelectric project on the river, joining 2,730-MW G.M. Shrum and 694-MW Peace Canyon Dam.

In 1976, BC Hydro chose Site C after finding Peace River Sites A, B, D, and E were not viable. Site C received an unexpected boost in 2009 when the British Columbia Utilities Commission rejected part of BC Hydro’s renewable energy acquisition plan, but approved study of Site C and a 1,000-MW expansion of the 1,805-MW Mica hydro project.

In the first of two solicitations, RFP 1519, BC Hydro seeks bids by 11 a.m., Pacific time, June 12 to provide geotechnical investigations at the Site C location, 7 kilometers southwest of Fort St. John. Work is to include seismic refraction investigations and petite seismic and downhole seismic profiling investigations on the north and south banks of the river.

In the second solicitation, RFP 1509, the utility seeks bids by 11 a.m., Pacific time, June 14 for drilling of exploratory holes in the existing Adit 5 to investigate and characterize in-situ stresses and rock moduli. Work is to include collection of about 140-millimeter outer diameter, 38-millimeter inner diameter over-cored rock samples and drilling of NQ-sized exploratory holes for deployment of down-hole or up-hole geophysical tools.
