The nearest transmission line to Pebble Beach is only a 230kV line, and even then, the line would need to be branched off ran out there (forgetting about the need to upgrade the entire regional network to fully upgrade the area to a redundant 500kV line), and Mount Edziza is in the middle of nowhere, with the nearest line being a 283kV line, with no 500kV line anywhere nearby.
In comparison, Site C is very well connected to the existing BC Hydro high voltage transmission system, and is scheduled for additional upgrades.

Furthermore, hydroelectric power is extremely cost-effective to operate and facilities have long service lives, both of which are attractive to BC Hydro as an operator, not just a power purchaser.
With that said, the cost of Site C is truly remarkable compared to the amount of power it will produce. 680MW, if that's accurate, honestly isn't very much production capacity for a facility allegedly to exceed $10B in capital costs. [Edit: the
Site C website says that dam will produce about 1,100MW and the estimated construction cost was $7.9B($2011)]
For comparison, the Revelstoke Dam has a production capacity for 2,480MW. Adding the planned sixth turbine would increase that to nearly 3,000MW. That would be roughly comparable to the output of the six CANDU nuclear reactors at Ontario's Pickering nuclear generating station that produce about 3,200MW. For futher comparison, the massive Bruce Nuclear Power Station in Ontario is the world's largest nuclear power plant by number of operational reactors (8) and is the second largest nuclear power complex in the world by installed generating capacity: a staggering 6,388MW(!). But since Japan shut down its Kashiwazaki-Kariwa in 2011, Bruce Power has become the world's largest operating nuclear power facility by generating capacity and reactor count.
I would like nuclear power to at least be considered among the range of potential options. There is a strong argument for nuclear in the context of a decarbonizing economy and the generating capacity that will be required to support mass adoption of electric consumer vehicles and commercial heavy transportation. The CANDU reactors in particular are a safe, efficient, and reliable design with the added benefit of being able to use unenriched uranium and a range of spent nuclear from light water reactors, including waste that is being stored on-site until permanent disposal site(s) are established. CANDU reactors can also use the nuclear material from decommissioned nuclear weapons and have the capability to breed thorium fuel for use in potential thorium reactors, should those reach commercial viability.
Nuclear produces no GHGs and can readily replace coal, oil, and gas for base-load grid power, complimenting intermittent production from renewables. With that said, I doubt that we will ever see a new nuclear power plant built in Canada, let alone BC. The real untapped renewable resource will be the steam shooting out the ears of environmental activists should nuclear power be proposed along the most seismically active parts of the coast.
