Fortis commissions 335-MW Waneta hydropower plant expansion

A 335 MW expansion of British Columbia’s Waneta hydropower complex has been completed, according to majority owner Fortis Inc.

Fortis, which bought a 51% share of the US$900 million project in August 2010, developed the expansion in partnership with Columbia Power and Columbia Basin Trust (CPCBT) — which is wholly owned by the provincial government.

The facility is located near the Waneta Dam on the Pend d’Oreille River. The expansion project also included the construction of a 10-kilometer-long, 230 kV transmission line.

Energy generated at the plant will be sold to BC Hydro and FortisBC under a 40-year power purchase agreement. reported in October 2010 that SNC-Lavalin had been awarded a $575.6 million contract to design and build the Waneta expansion after Fortis concluded definitive agreements for the project with CPCBT earlier that month.

The Aecon Group was named to work jointly with SNC-Lavalin on the plant’s construction later in November 2010.
