Proposed seismic upgrades to the Strathcona and Ladore dams on the Campbell River hydroelectric system, along with an already approved project to strengthen the John Hart dam, could cost a total of $1.17 billion to $1.74 billion, according to B.C. Hydro estimates.
In June, B.C. Hydro submitted proposals for Strathcona and Ladore improvements to the B.C. Utilities Commission for approval.
The commission earlier gave the green light to seismically upgrade the John Hart dam, estimated to cost $646 million to $923 million. The cost range covers the time from when the project was initiated in 2014 to its completion in 2030.
For the Ladore project, cost estimates run from $225 million to $344 million, while the Strathcona project range is $302 million to $474 million.
