BC Hydro names contractor for 500-MW Revelstoke Unit 5

BC Hydro awarded a contract to Peter Kiewit Sons Co. for civil works and a penstock for a 500-MW unit to be added to 1,980-MW Revelstoke Dam on the Columbia River in British Columbia.

Although the value of the contract was not disclosed, capital cost estimates for the entire Revelstoke Unit 5 project ranged from C$280 million to C$350 million (US$290 million to US$363 million). (HNN 7/31/07)

Peter Kiewit was selected in October from a solicitation in which BC Hydro called for: construction of civil works, including removal of some concrete, supply and placement of reinforced concrete for the generator, and embedding of turbine parts and related works; and the supply and installation of a steel penstock, connecting it to existing top and bottom penstock sections already on the dam’s face.

Construction for the new unit is to begin by year’s end. The targeted in-service date for the unit is October 2010.

In addition to bids for the Unit 5 work, BC Hydro asked for optional pricing for the civil works and penstock for the possible addition of a sixth turbine-generator at Revelstoke. However, Accenture Business Services for Utilities, a service provider to BC Hydro, declined to comment on prices submitted for a sixth unit.
